23 ## 1.1 Objectives and ambition
24
25
26 Throughout this Grant Proposal, you will note that we are making
27 significant use of ideas from the early days of Computing. Due to
28 the limitations of physical technology at that time, these ideas were
29 categorised into "technology that was beyond delivery". Industry-standard
30 computing from then to today missed many of those opportunities and
31 has consequently ploughed narrow "technological ruts" in an incremental
32 fashion that has detrimentally impacted and constrained all world-wide
33 Computing end-users as a result. Modern hardware technology performance
34 is now allowing us to revisit the best of the "Sea of ideas" from the
35 history of the past 60 years of computing. Our Grant Application is
36 therefore based on firm, practical proven foundations, backed up by a
37 real-world customer requirement: Advanced high-accuracy GPS Sensor-Fusion,
38 to prove the core's capabilities and energy efficiency.
39
40
41 We have chosen to evolve core technology to develop a Next-Generation
42 Supercomputer-scale Microprocessor family based on an existing
43 2-decades-proven base (the Power ISA), with Advanced Cray-style Vectors,
44 providing energy-efficient advanced computational power by a unique
45 methodology not currently being achieved by any current general-purpose
46 computing device. We have been working on this strategy for over three
47 years and our grant application is now evolutionary but was revolutionary.
48
49
50 Libre-SOC has, for over three years, been backed by EU Funding through
51 NLnet and now NGI POINTER, and at the core of our work we have been
52 developing a novel Draft Vector ISA Extension to the OpenPOWER ISA,
53 called SVP64. https://libre-soc.org/openpower/sv/svp64/ and an enhanced
54 processor core architecture on which it will run.
55
56
57 As an aside we must acknowledge the research work of IBM labs who designed
58 and then Open-Licensed their Power ISA: the foundation on which we have
59 been building. Standing on the shoulders of greatness is never a bad
60 place to start.
61
62
63 SVP64 contains features and capabilities never seen in any Instruction
64 Set Architecture (ISA) of the past sixty years. With NLnet's help we have
65 TRL (3) implementations and simulations demonstrating a 75% reduction in
66 the program size of core algorithms for Video and Audio DSP Processing
67 (FFT, DCT, Matrix Multiply), and these still need optimized, which if
68 successfully expanded to general-purpose algorithms would result in huge
69 power savings if deployed in mass-volume end-user products.
70
71
72 Why we are leveraging the Power ISA as the fundamental basis instead of
73 "completely novel non-standard computing architecture" requires some
74 explanation, best illustrated by reference to other historic high
75 capability designs. Aspex Microelectronics ASP was a 4096-wide SIMD
76 Array of 2-bit processors. It could be programmed at a rate of one
77 instruction per 5-10 days. Elixent also had a similar 2D Grid Array of
78 4-bit processors. Both were ultra-power-efficient (2 orders of magnitude
79 for certain specialist tasks) but were impossible to program even for the
80 best programming minds and required critical assistance from a severely
81 limited pool of specialists for best exploitation. The Industry-standard
82 rate for general-purpose High-Level programming (C, C++) is around 150
83 lines of code per day, not 5-10 days per line of assembler. We seek to
84 deliver a much more accessible "general-purpose" Microprocessor that
85 contains Supercomputing elements and consequently stands a much more
86 realistic chance of general world-wide adoption (including Europe).
87
88
89 An additional insight: OpenRISC 1200 took 12 years to reach maturity.
90 The team developed the entire processor architecture, low-level software
91 and compiler technology, entirely from scratch. We considered this
92 approach and, due to the long timescales, rejected it, choosing
93 instead to leverage and be compatible with a pre-existing Open ISA:
94 OpenPOWER. We also considered RISC-V however it turns out to be too
95 simplistic (https://news.ycombinator.com/item?id=24459041) and it is
96 far too late to retrospectively add Supercomputer-grade power-efficient
97 functionality to its design or instruction set. With the IBM-inspired
98 Power ISA already being a Supercomputer-grade ISA, it is a natural fit for
99 an energy-efficient Cray-style Vector upgrade, and comes with 25 years
100 of pre-existing software, libraries, compilers and customers. By being
101 backwards-compatible with the existing Power ISA 3.0 (which is now an
102 Open ISA managed by the OpenPOWER Foundation), European businesses will
103 benefit from that pre-existing decades-established stability and pedigree.
104
105
106 As hinted at, above: Great hardware is nothing without the corresponding
107 compiler technology and support libraries. Consequently we need to engage
108 with Compiler Service Companies (Embecosm Gmbh, Vrull.eu) to evaluate the
109 feasibility of adding Vectorisation support to gcc, llvm and low-level
110 standard libraries. Whilst Libre-SOC has already demonstrated TRL (3)
111 successful assembly-level SVP64 algorithms (MP3 CODEC in particular),
112 assembler is far too low-level for general-purpose compute. C, C++
113 and other programming language support is required to be evaluated
114 and developed. Also given that the Libre-SOC Core is being long-term
115 designed for energy-efficient 3D GPU and Video Processing workloads,
116 two 3D Vulkan Drivers (Kazan and MESA3D) need to be taken beyond
117 proof-of-concept (TRL 2/3).
118
119
120 We consider it strategically critical to develop processors in an entirely
121 transparent fashion. The current Silicon Industry chooses secrecy to mask
122 technology shortcuts and restrictive cross licencing, which inevitably and
123 systematically fails to provide trustable hardware: Intel's Management
124 Engine; Qualcomm making 40% of the world's smartphones vulnerable to
125 hacking; Apple drive-by Zero-day Wireless exploits; Super-Micro being
126 delisted from NASDAQ for failing to be able to prove the provenance of
127 all hardware and software components. We consider Libre / Open Hardware
128 ASICs and the full Libre/Open VLSI toolchain itself to be fundamental
129 to end-user trust and security as well as Digital Sovereignty.
130
131
132 In addition to this, Libre-SOC has already been developing Mathematical
133 Formal Correctness Proofs for the HDL of its early prototype designs,
134 which, in combination with unrestricted access to the HDL Source Code,
135 allow third parties including customers to perform their own verification
136 of the ASIC's purpose (as opposed to the customer having to trust a
137 manufacture that inherently has a direct conflict-of-interest in the form
138 of its Shareholders and profits). Furthermore, we aim to experiment with
139 built-in "tamper-checking" circuits that, on running a test programme on
140 our evaluation test bed, will provide an Electro-Magnetic "signature".
141 By publishing this "signature" and the test programs, customers can
142 verify that their purchased ASICs have the same EMF "signature" and can
143 detect immediately if the ASIC has been tampered with. In addition we
144 will continue existing (TRL 2) research into Hardware-level Speculative
145 Execution mitigation techniques. We feel that the full combination of
146 these objectives meets the Hardware Security requirements of this Call.
147
148
149 This strategy does not end with just the HDL: thanks (again) to NLnet
150 we have been collaborating already with Chips4Makers, LIP6 and CNRS
151 (all funded by EU Grants), to advance the state-of-the-art for European
152 VLSI Tool Technology, which is important to European Silicon Sovereignty.
153
154
155 https://www.europarl.europa.eu/RegData/etudes/BRIE/2020/651992/EPRS_BRI(2020)651992_EN.pdf
156
157
158 We are however significantly concerned that the LIP6 Department, as
159 an Academic body, is inevitably underfunded, particularly when it is the
160 sole provider of Libre/Open VLSI Silicon-proven software in the whole
161 of Europe. This is why we have included an Engineering Supplement for
162 LIP6 and CNRS in the Libre-SOC budget, to contract engineering support
163 for them and to avoid employment complications due to the French Civil
164 Service Regulations, which lack the flexibility needed. These engineers,
165 who are in high demand, will work for Libre-SOC/RED Semiconductor Ltd
166 but be fully available to assist in the development work covered by the
167 grant being done by LIP6 and CNRS.
168
169
170 The consequential effect of this tool development will be to help
171 create VLSI tools that can be directly substituted for the existing
172 commercial (and geopolitically constrained) tools from companies such as
173 Cadence and Mentor, giving a Euro-centric independence from “technology
174 constraining” acts.
175
176
177 We are currently awaiting the return of our first 180 nm architecture
178 test ASIC (TRL 4) from TSMC, through IMEC. It is the first major
179 silicon in Europe of its size (5.1 x 5.9 mm^2 and 130,000 cells)
180 to be entirely developed using a Libre-Licensed VLSI ASIC toolchain,
181 and the world's first Power ISA 3.0 outside of IBM to reach Silicon in
182 over 12 years. We have already started to push (drive) the evolution of
183 Europe's only silicon-proven Libre/Open VLSI toolchain, something this
184 Grant application will support and will allow LIP6 and CNRS to enhance
185 it to lower geometries and larger ASIC sizes which will be critical to
186 European businesses' Digital and Silicon Sovereignty.
187
188 For the avoidance of confusion the use of the word "Cell" refers to a
189 bounded piece of electronic design that when used together, like bricks,
190 form larger more complicated electrical functions.
191
192 To help advance Digital Sovereignty, LIP6 and CNRS need to once
193 again push the boundaries of the Libre/Open VLSI toolchain, coriolis2
194 Place-and-Route, https://coriolis2.lip6.fr and HITAS/YAGLE Static Timing
195 Analyser https://www-soc.lip6.fr/equipe-cian/logiciels/tasyagle/ both
196 of which are, at the lower 360 and 180 nm geometries, at TRL 9, but are
197 at TRL 2 for lower geometries 90, 65, 45 nm and below.
198
199
200 Chips4Makers (also NLnet funded) created FlexLib Libre/Open Cell
201 Libraries which allows porting of Standard Cell Libraries to any geometry.
202 An NDA'd TSMC 180nm version of FlexLib was created for the Libre-SOC
203 180nm test ASIC. To achieve our objectives, RED Semiconductor,
204 Libre-SOC, LIP6 and CNRS will need to
205 create smaller geometry ports of FlexLib. These Cell Libraries need to
206 be tested in actual Silicon, and consequently we will be working with
207 IMEC as a sub-contractor and partner to deliver MPW Shuttle Runs for
208 these critical Libraries, using Libre-SOC Cores as a "proving-ground".
209

211
212
213 In addition, NLnet, a Stichting / Foundation, has been so successful
214 in supporting "Works for the Public Good" that we feel that their approach
215 and service fulfilment are extremely relevant to this Call. During the
216 36 month duration of the proposal, NLnet is in a position to engage
217 with Libre/Open Hardware and Software developers which, for our team,
218 will mitigate the risk of unanticipated issues requiring specialist but
219 small-scope funding, that yet still meets the well-defined objectives
220 of this Call.
221
222 To put all of this to practical use, Helix Technologies, by defining
223 an advanced GPS Correlator, will set a Computational capability objective
224 for the core technology and be a Reference test-bed. Helix will then
225 be able to carry out the comparative studies which show that the core
226 technology meets significant performance/watt improvements. The ultimate
227 destination for some of these devices will be Satellites (Space).
228
229 Summary of why our work is pertinent to Call HORIZON-CL4-2021-DIGITAL-EMERGING-01-01:
230
231
232 * High-performance energy-efficient computing: SVP64 is a Cray-style Vector ISA. Cray-style Vector ISAs are known to produce smaller and more compact programs. Smaller programs means less L1 Cache misses, and overall, smaller L1 Caches are needed. This results inherently in greatly-reduced power consumption, whilst also remaining practical and general-purpose programmable.
233 * Targeted applications: We are developing a general-purpose Hybrid Architecture suitable for 3D, Video, Digital Signal Processing, Cryptographic applications, AI and many more. As it is general-purpose it covers all these areas. However in certain areas "specialist" instructions are needed (particularly 3D) and we seek additional funding to complete them. This includes Helix's high-accuracy GPS application which qualifies as a step-improvement in "Sensor fusion".
234 * Hardware-software co-design and Libre/Open Hardware-Software: as all participants are trained as Software Engineers, we inherently and automatically bring Software Engineering practices and techniques to Hardware design, and consequently achieve a far greater effectiveness and flexibility. Additionally, all participants are long-term contributors to Libre/Open Software and Hardware Projects. This shall continue throughout this Grant proposal. The involvement of RED Semiconductor Ltd brings further semiconductor hardware experience, bringing balance to the overall team.
235 * Moore's Law and changing Economics: as a general-purpose Cray-style Vector Supercomputer ISA, what we are designing may deploy either "Fast and Narrow" back-end (internal) micro-architecture, or "Slow and Wide": huge numbers of SIMD ALUs running at a much slower clock rate. The beauty and elegance of a Vector ISA is that, unlike SIMD ISAs such as AVX-512, NEON and to a partial extend SVE2, is that the programmer doesn't need to know about the internal micro-architecture, but their programs achieve the same throughput, even on larger geometries.
236 * Hardware-based security: We consider it deeply unwise to follow the false practice of "adding more complexity to achieve more security". Security is achieved through simplicity and transparency. Simplicity: we studied historic Supercomputer designs dating back to 1965 (CDC 6600) where pure pragmatism required simpler and more elegant designs. Transparency: Fully Libre/Open designs that customers can themselves verify by running Formal Correctness Proofs (where those tools are also Libre/Open Source). Fully Libre/Open VLSI toolchains and Cell Libraries (no possibility of insertion of spying at the Silicon level). "Tripwires" embedded into the silicon to gauge area-local EMF "Signatures". Additionally, we already have work underway into Out-of-Order Execution and seek to explore Speculative Execution Mitigation techniques at the hardware level, to increase security. These are practical achievable demonstrable ways to achieve Hardware-based trust.
237 * Security and Safety-critical Guidelines: Due to our overall approach, although potentially inherently achievable by others utilising our work as the basis for ongoing Research, the main participants consider it out of scope due to practical time constraints. Security Certification typically takes 5 to 7 years: The scope of this project is only 3. NLnet however may fund work that does indeed take into account these criteria.
238 * ASIC (Chip) prototyping: We are developing RTL including High-Level (core designs) as well as Low-Level (Cell Libraries). Nobody in any European Company will use a Cell Library if it has not been demonstrated as Silicon-Proven. As we already did with the 180nm ASIC, the best way to prove that a Cell Library (and an innovative approach - using Libre/Open VLSI toolchains) works is to do an actual ASIC.
239
240
241 Additional notes:
242
243
244 1. With regard to "Improve by two orders of magnitude the performance/watt for targeted Edge Applications", subject to Moore's Law and other limitations, such as geometry of devices we are moving in this direction, and whether we can achieve it will be subject to the available manufacturing processes we can afford during the scope of this Grant. We have already achieved one magnitude of improvement in simulation (TRL 3) of FFT, DCT and other DSP calculations. As already indicated above, the output of our design can be run on many different geometries of significantly-different performances.
245 2. You will note that a significant number of our technology collaborators and the technology and services that we rely on are already funded by EU Grants. Through RED Semiconductor Ltd, we are going to be the conduit to commercial realisation of value for this investment, with subsequent commercial benefits of employment and tax revenues across the EU. We know not to lose sight of the fact all EU funding is fundamentally focused on future commercial success.

254
255
256 ## 1.2 Methodology
257
258
259 * Everything that Libre-SOC does is published as Libre/Open Information at https://libre-soc.org/ - source code (https://git.libre-soc.org) is open and available under the LGPLv3+ License and other appropriate Libre/Open Licenses.
260 * LIP6 likewise discloses all source code at https://gitlab.lip6.fr/vlsi-eda
261 * LIP6's toolkit containing existing large-geometry Cell Libraries and test benches at https://gitlab.lip6.fr/vlsi-eda/alliance-check-toolkit.
262 * CNRS's HITAS/YAGLE is also Open Source https://www-soc.lip6.fr/equipe-cian/logiciels/tasyagle/.
263 * Symbiyosys and its subcomponents for Formal Correctness Proofs are Libre/Open https://symbiyosys.readthedocs.io/.
264 * GPS GNSS-SDR is also Open Source https://gnss-sdr.org/ and can be adapted for Helix's requirement
265 * Chips4Makers FlexLib is also Open Source https://gitlab.com/Chips4Makers but the NDA'd "ports" are not.
266 * To solve the above problem, all Libre/Open Developers will work with an Academic "Ghost" version, called C4M-FreePDK45 https://gitlab.com/Chips4Makers/c4m-pdk-freepdk45. This "ghost" version will allow full (parallel-track) collaboration between Libre/Open Developers and those Participants creating "real" GDS-II Files, without violating Foundry NDAs.
267
268
269 This methodology is based on an established process that has already
270 allowed us to deliver demonstrable software and hardware results,
271 the manifestation of which is our 180nm architecture test chip now
272 in manufacture. This has involved a significant amount of cooperative
273 development among the applicants, and others beyond, and the development
274 of core supporting technology that this grant application can now
275 efficiently build upon.
276
277
278 We refer to other supporting technology sources further in this
279 application and whilst they are not the core team they will critically
280 contribute to the overall success. In particular, these groups can be
281 supported by NLnet, whose "Works for the Public Good" remit is 100%
282 compatible with the full transparency objectives (that the project's
283 participants are already committed to) which will help by providing
284 additional non-core-team development on an on-demand basis, on the back
285 of NLnet's already-trusted commitment to fulfil European Union objectives
286 under Grant Agreements No 825310 and 825322.
287
288
289 Additionally, Libre-SOC is working closely with the OpenPOWER Foundation
290 ISA Working Group Chair, having attended regular bi-weekly meetings for
291 over 18 months. As mentioned above, the entirety of our work of greater
292 than 3 years on this Vector Extension, SVP64, is entirely transparent
293 and open: https://libre-soc.org/openpower/sv/svp64/. Both NLnet
294 (and StandICT.eu through a proposal under consideration at the time of
295 writing) are supporting our efforts to submit the Draft SVP64 and its
296 subcomponents through the RFC (Request for Change) process being developed
297 by the OpenPOWER Foundation. For long-term stability and impact it is a
298 necessary prerequisite that Draft SVP64 become an official part of the
299 Power ISA: this decision is however down to the OpenPOWER Foundation
300 and requires considerable preparation and planning, which this Grant
301 will help support.
302
303
304 One huge benefit of Libre-SOC's core being Power ISA 3.0 Compliant is that
305 IBM contributed a huge patent pool through the OpenPOWER EULA. Compliant
306 Designs enjoy the protection of this patent pool. By contributing SVP64
307 to the Power ISA it falls under this same umbrella. Libre-SOC shall be
308 entering into an agreement with the OpenPOWER Foundation, here, as part
309 of the ISA RFC process. European businesses clearly benefit from the
310 long-term stability of this arrangement.
311
312
313 Whilst we clearly need, ultimately, to prove our design's power-efficiency
314 in silicon, we would however consider it unwise and extremely costly to
315 tape-out to Silicon without having gone through a proper early-evaluation
316 process, weeding out ineffective strategies and designs. To that end, we
317 learned from Jeff Bush's work on the Nyuzi 3D core to perform estimates
318 on power consumption and clock cycles. This is a highly-effective
319 feedback process that allows identification and targeting of the most
320 urgent (inefficient) areas, and we have taken it on-board and adopted
321 it throughout the project.
322
323
324 Part of that involves Peter Hsu's cavatools (another NLnet Grant) which
325 is (at present) a cycle-accurate Simulator for RISC-V. A (new) NLnet
326 Grant (not yet approved at the time of writing) is targeted at porting
327 cavatools to the Power ISA. This proposal would allow NLnet-funded work to
328 be extended into 3D, Video, DSP and other areas, to simulate (test) out
329 the feasibility, power-efficiency and effectiveness of different Custom
330 SVP64 Extensions to the Power ISA, long before they reach actual Silicon.
331
332
333 # 2 Impact
334
335
336 ## 2.1 Project’s pathways towards impact
337
338
339 The core of modern computing is the capability of the computational
340 element of the systems and the microprocessors they are based around.
341 Every twenty years there has been a significant evolutionary step in the
342 technical concepts employed by these microprocessor devices. For example
343 the last big step was the concept of RISC (Reduced Instruction Set)
344 processors. These developments have been driven by many forces from
345 cost of devices to limitations of the available technology of the time.
346
347
348 The Libre-SOC core is capable of becoming the next significant step
349 change in microprocessor speed, technology, and reduction in equivalent
350 computational power (Watts).
351
352
353 To illustrate this, we need to go back in history to early computing.
354 The first microprocessors were reliant on expensive core then bipolar
355 memory and even with the advent of DRAMS (Dynamic Random-Access Memories)
356 the primary focus of microprocessor processor core designs was to
357 optimise the minimal use of memory and focus on the power of the core.
358 Over time, memory became cheaper and reliance on memory to improve
359 processing increased with techniques like RAMdisk stores were developed.
360 This cheap memory also resulted in the evolution of RISC and similar
361 computing technology concepts. Today the problem is epitomized by speed,
362 where microprocessors have evolved to be much faster than the fastest
363 memories, and to increase performance, the state of the art computing
364 requires coming full-circle: once again minimising the use of memory,
365 which is now a log jam, and looking again at the core optimisation
366 solutions devised in the 1960’s by luminaries such as Seymour Cray.
367 The Libre-SOC core is an optimal adoption of this category of core
368 processor performance enhancement.
369
370
371 Libre-SOC has the benefit that its development relies on fundamental
372 research that has been known and proven for nearly 60 years. SVP64 has
373 input from and takes on-board lessons learned from NEC SX-Aurora, Cray-I,
374 Mitch Alsup's MyISA 66000, RISC-V RVV Vectors, MRISC32, AVX-512, ARM
375 SVE2, Qualcomm Hexagon and TI's DSP range, as well as other more esoteric
376 Micro-architectures such as Aspex's Array-String Processor and Elixent's
377 2D Grid design.
378
379
380 As a Hybrid (merged) CPU-VPU-GPU Micro-architecture (similar to
381 ICubeCorp's IC3128) there is a huge reduction in the complexity
382 of 3D Graphics and Video Driver and overall hardware. NVidia, ARM
383 (MALI), AMD, PowerVR, Vivante: these are all dual (ISA-incompatible)
384 architectures with staggering levels of hardware-software complexity.
385 Like ICubeCorp's design, Libre-SOC 3D and Video binaries are executed
386 directly on the actual main (one) core.
387
388
389 The end-result here is, if deployed in mass-volume products world-wide
390 including for European end-users of ubiquitous Computing devices, a
391 significant energy saving results on a massive scale, particularly in
392 battery-operated (mobile, tablet, laptop) appliances. Demonstrating this
393 however requires, ultimately, that we actually create real silicon,
394 and measure its performance and power consumption.
395
396
397 ## 2.2 Measures to maximise impact - Dissemination,
398 exploitation and communication
399
400
401 As the Libre-SOC core is the result of a Libre/Open Source project
402 by default all of our development work has been published for the last
403 four years. This was also a requirement of our EU funding through NLnet.
404 In addition we have undertaken a full program of conference presentations,
405 technology awareness activities and cooperation with key bodies such as
406 the OpenPOWER Foundation and OpenPOWER Members (Libre-SOC is participating
407 in a world-wide Open University Course about the OpenPOWER ISA, an
408 activity led by IBM). Examples:

423
424 Luke Leighton also releases videos of his Libre-SOC talks on
425 youtube https://www.youtube.com/user/lkcl and a full list of all
426 conferences (past and present) are maintained on the Libre-SOC website
427 https://libre-soc.org/conferences/
428
429
430 The Libre-SOC bugtracker (where we track our TODO actions) is
431 public access (https://bugs.libre-soc.org), and the Mailing
432 lists are also public access (https://lists.libre-soc.org).
433 LIP6's alliance/coriolis2 mailing lists are also public access
434 (https://www-soc.lip6.fr/wws/info/alliance-users)
435
436
437 These are ongoing activities that actively encourage world-wide Open
438 Participation, and shall remain so indefinitely. We will continue to
439 grow these activities along with a commercial thread of publicity by RED
440 Semiconductor Ltd to publicise and determine product family opportunities
441 where RED Semiconductor Ltd will focus on potential product and market
442 development built upon the Libre-SOC core technology.

445 ## 2.3 Summary
446
447
448 ### Specific needs
449
450
451 Modern computing technology is designed in secrecy and released to
452 the market without the ability of the user base to vet or validate.
453 When problems arise it is usually due to “discovery” and usually
454 driven by technical curiosity or malice. What is clear is that to those
455 on the inside these problems were visible from the outset, however
456 time resource and unwillingness to explore (and unethical Commercial
457 pragmatism) has left these vulnerabilities open to be exploited. As a
458 general principle we have taken the view that any new design should be
459 open to review and able to be corrected (every design has some bugs)
460 before mass adoption and the inevitable loss and crisis.
461
462
463 In practical terms: as indicated in sections above there have
464 been a number of security incidents involving ubiquitous computing
465 devices, impacting millions to hundreds of millions of end-users,
466 world-wide. Qualcomm failed last year to provide adequate secure firmware,
467 leaving 40% of the entire world's Android smartphones vulnerable to
468 attack. With the majority of smartphones being "fire-and-forget" products
469 with non-upgradeable firmware, the end-user's only solution is to throw
470 away a perfectly good electronics product and purchase a new one.
471 For Intel products - all Intel products - the exact same thing has
472 occurred (Master Firmware Key, Spectre, Meltdown), but at an unfixable
473 hardware level, and there are no replacement Intel products that can be
474 purchased in the market to "fix" their fundamental design flaws.
475
476
477 Not only that, but all of the ubiquitous Computing products (Apple, Intel,
478 IBM, NVidia, AMD being the most well-known) are 100% non-EU-based. As far
479 as EU Digital Sovereignty is concerned, this is an extremely serious
480 and alarming situation, compounded by critical Foundries and know-how
481 to run those Foundries also not being part of a Sovereign European remit.
482
483
484 If that was not enough, Foundries and the Semiconductor Industry requires
485 NDAs that at the minimum prohibit full publication of Academic results,
486 stifling innovation and research, in turn driving up the cost for EU
487 businesses of the cost of ASIC products by creating artificial cost,
488 overhead and knowledge barriers.
489
490
491 The entire Computing and Semiconductor Industry needs a new approach.
492
493
494 Taking the initiative, the end goal of the Libre-SOC/RED Semiconductor
495 Ltd project is therefore to deliver high performance, security auditable,
496 supercomputer class computing devices to the market. As this is not
497 currently available it will prompt a step change in low power (Watts)
498 high performance computing. This will be achieved through:
499
500
501 * Energy/Power consumption measurement: we need to verify that performance/watt is lowered
502 * Draft SVP64 inclusion in Power ISA: this is needed to indicate "Official long-term Status"
503 * Auditability and Transparency: needed for end-users and EU businesses to trust the hardware.
504 * Power ISA 3.0 Interoperability: to leverage over 2 decades of existing business software tools.
505 * FPGA and Simulator demonstrators: to demonstrate feasibility of the HDL and the ISA
506 * VLSI toolchain and Cell Library: MPW Shuttle runs are needed to reach "Silicon-proven" status
507 * NLnet mini-grants: Effectively this is a "Reserve" budget for the Project, managed by NLnet
508
509
510 ### Dissemination, exploitation and Communication
511
512 Energy/Power consumption measurement:
513
514
515 Just as Jeff Bush showed by publishing Nyuzi Research at Conferences we
516 shall follow the same proven incremental performance/watt measures and
517 procedures, and publish the results.
518
519 https://ieeexplore.ieee.org/document/7095803/
520
521
522 Draft SVP64 inclusion in Power ISA:
523
524
525 We are already working with the OpenPOWER ISA Working Group, and have
526 already begun publishing the Draft SVP64 Specification as it is being
527 developed. This will become official RFCs (Request for Changes) leading
528 to adoption. This includes development of Compliance Test Suites,
529 low-level libraries, compilers etc. which shall be announced through
530 Conferences, Press Releases (by RED Semiconductor Ltd, NLnet and the
531 OpenPOWER Foundation) and standard Libre/Open development practices
532 (Mailing list Announcements).
533
534
535 Auditability and Transparency:
536
537
538 Using symbiyosys we have already established a number of Formal
539 Correctness Proofs for the TRL 3 HDL used in the 180nm ASIC: This
540 needs to be extended right the way throughout all future work and be
541 published for other OpenPOWER Foundation Members and European businesses
542 to be able to independently verify the correct functionality of not just
543 Libre-SOC ASIC designs but other Power ISA 3.0 compliant designs as well.
544 Libre-SOC HDL and the associated Formal Correctness Proofs are published
545 as-they-are-developed in real-time and consequently dissemination is
546 implicit and automatic.
547
548
549 For the Silicon-level "EMF signature" measurement system Libre-SOC
550 will define and publish Reference Standards, test applications and
551 methodology documentation. RED Semiconductor Ltd will establish
552 and make available a "expected results" database for its commercial
553 products, as part of its Product Application Documentation, so that
554 European Businesses may independently verify that their commercial
555 off-the-shelf RED Semiconductor Ltd products have not been tampered with
556 at the Silicon level. (It is beyond the scope of this Grant however RED
557 Semiconductor Ltd will publish its overall Quality Standards Strategy).
558 In concept, the "EMF Signature" strategy is very similar to Hewlett
559 Packard's "Signature Analysis Strategy" that has been around since
560 1949. https://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1977-05.pdf
561
562
563 Power ISA 3.0 Interoperability:
564
565
566 Standing on the shoulders of Giants (IBM and other OPF Members in
567 this case) is always a good starting point. The familiarity and
568 decades-long-term stability of the existing Power ISA 3.0 gives us a vast
569 existing-established user audience to whom we can provide training and
570 experience upgrades from an existing high-level of knowledge. In this
571 we already have the cooperation of IBM (through the OpenPOWER University
572 Education Course that Libre-SOC has helped to create - to be first run
573 from 18th-29th October 2021).
574
575
576 We will take the Interoperability further at a practical level
577 by developing a Libre/Open Power ISA 3.0 "Compliance Test
578 Suite" that meets the OpenPOWER Foundation documented standards
579 (https://openpowerfoundation.org/openpower-isa-compliance-definition/)
580 and make it entirely public and available to all without limit, and invite
581 other OpenPOWER Foundation Members to participate in its development
582 and use. This will then be, again, announced through Press Releases
583 and Mailing List as well as Conference Presentations.
584
585
586 FPGA and Simulator demonstrators:
587
588
589 Again: all new software tools created, and existing ones used and modified
590 to both develop and use resultant devices will be published as an inherent
591 part of the OpenSource real time publishing strategy.
592
593
594 VLSI Toolchain and Cell Library verification:
595
596
597 Again: the results of the development are, to date and in the future,
598 part of Libre/Open Source projects, and are therefore fully-visible, even
599 though they are Hardware-related we treat them as Open Source Software.
600 Conference presentations shall therefore be given, announcements on
601 Mailing Lists, as part of the overall communications strategy.
602
603
604 In this particular case however, the communication has to involve the
605 results of the MPW Shuttle runs, testing the actual ASICs, because it
606 is critical to demonstrate and communicate that the Cell Libraries are
607 Silicon-Proven and that the VLSI tools were capable of successfully
608 creating that Silicon-Proven layout. However the caveat here: anything
609 involving NDA'd material as required by the Foundry has to remain
610 confidential (note that this is not something that can be addressed
611 within the funding scope of this Call)
612
613
614 NLnet mini-grants:
615
616
617 NLnet's website has already been established with communication facilities
618 for around 19 years. NLnet are experienced in the effective evaluation
619 and management of small-scale Grants. They are also extremely familiar
620 with the work that we are doing, and with the detail of EU Grant
621 Procedures. Following those procedures they will add a new section to
622 the website for Grant Proposals that inherently meet the objectives of
623 this Call, and will use their existing communications infrastructure to
624 maximum benefit.
625
626
627 ### Expected results
628
629
630 Energy/Power consumption measurement:
631
632
633 We anticipate in the actual ASIC a significant measurable reduction in
634 performance/watt. Early predictions shall be based on Instruction-level
635 Simulations, but these need to be validated against the "real thing".
636 Due to the iterative process (outlined by Jeff Bush) we simply cannot
637 state exactly in advance the full magnitude of improvement that will
638 occur. The process itself, and how it was successfully applied, however,
639 will be considered to be part of the results themselves as part of
640 publications online and at Conferences.
641
642
643 Draft SVP64 inclusion in Power ISA:
644
645
646 The ultimate outcome here is that SVP64 becomes an officially-adopted
647 part of the OpenPOWER ISA, including a full compliance test suite,
648 documentation in a future revision of the official Power ISA Technical
649 Reference Manual. This process is, however, by necessity and being an
650 extremely important responsibility of the OpenPOWER Foundation (not of
651 any of the Participants), very slow and outside of our control, and may
652 take longer than the 36 month duration of the Grant to complete.
653
654
655 Therefore, the critical Milestone shall be our submission to the
656 OpenPOWER Foundation's ISA Working Group, as well as the development of
657 the required Compliance Test Suites. Both of these shall be published
658 under appropriate Libre/Open Licenses.
659
660
661 Auditability and Transparency:
662
663
664 We will have completed the Formal Correctness Proofs and published them
665 and the results of running them against the Libre-SOC HDL. We will also
666 have received the ASICs back from MPW Shuttle runs, which will contain
667 "EMF detection" wires routed strategically throughout it, and run the
668 pre-arranged unit tests that will create "Signatures" that shall be
669 recorded and published. This task is another critical reason why we
670 need actual Silicon, because only with an ASIC can we demonstrate the
671 viability of Signature Analysis (and similar) Strategies for ASICs.
672
673
674 Power ISA 3.0 Interoperability:
675
676
677 We will have completed an implementation of the Compliance Test
678 Suite as a Libre-Licensed application that can test multiple different
679 implementations: FPGA, Simulators (including our own as well as qemu), and
680 actual Silicon implementations including IBM POWER9, POWER10, Microwatt.
681 In addition we will have extended our own interoperability "Test API"
682 that allows comparisons of any arbitrary user-generated application
683 against any other arbitrary Power ISA compliant devices (whether FPGA,
684 Simulator, or Silicon): the OpenPOWER Compliance Test Suite implementation
685 shall simply be one of those applications.
686
687
688 We expect the Libre-SOC core to pass the full OpenPOWER ISA 3.0 Test
689 Suite, and the results to be published. We will also communicate with
690 OpenPOWER Foundation Members and make them aware of the existence of
691 the Test Suite and document how it may be used to test their own Power
692 ISA 3.0 implementations for Compliance.
693
694
695 FPGA and Simulator demonstrators:
696
697
698 Successful software simulation (emulation) of the augmented Power 3.0 ISA
699 with the Draft SVP64 Extensions, and successful demonstration of the HDL
700 of a multi-core SMP processor implementing the same, running in a large
701 FPGA (the size of the commercially-available FPGAs constraining what
702 is possible, here). Each shall help verify the other's correctness.
703 This will be a rapid iterative cycle of development and shall always
704 produce early results, feeding back to continued improvement.
705
706
707 VLSI Toolchain and Cell Library verification:
708
709
710 Multiple demonstrator 2-core ASICs and a proven path to an 8-core ASIC
711 (as we anticipate that the 8-core is likely to be beyond the scope of the
712 Grant due to Silicon costs). Where the 2-core ASIC MPW is multi-purpose
713 (proving the HDL, proving the VLSI toolchain, proving the Cell Library)
714 and shall use the FPGA and Simulations to check its correctness before
715 proceeding, the 8-core shall remain in FPGA only, due to cost, but a
716 VLSI Layout for the 8-core will still be attempted, in order to "test
717 the limits" of the VLSI tools. If funding was available we could take
718 the 8-core to full MPW rather than just to FPGA and GDS-II. As the 8
719 core Layout develops, if it (and the coriolis2 toolchain) progresses
720 to viability in the 36 months one option might be for RED Semiconductor
721 to apply for a EUR 500,000 NLnet mini-grant, payment terms to meet
722 requirements set by IMEC, from their budget allocated under this proposal.
723
724
725 NLnet mini-grants:
726
727
728 NLnet will receive and review potentially hundreds of small Grant
729 Proposals to ensure that they meet both the Call's Objectives and meet
730 NLnet's responsibilities as a Stichting / Foundation to fund "Works
731 for the Public Good". They shall request that the successful Grant
732 Applicant create Milestones and that Grant Applicant communicate those
733 results, thus requiring that it is the Grant Applicant that fulfils the
734 requirement herein. This process is already established and already in
735 effect under Grant Agreements No 825310 and 825322.
736
737
738 In the case of the Participants, if we need "reserve" budgets for
739 unforseen activities, we commit to following that exact same procedure
740 and thus also shall meet the Objectives of this Call (examples include
741 the MPW 8-core, above). We are aware that new technology beneficial to
742 the project may not be currently apparent but will be available within
743 the 36 months duration, and the methodology of funding it through NLnet
744 may prove optimal and a cost-effective use of EU funds, as NLnet would
745 (as they do now) only draw the budget down as needed.
746
747
748 ### Target groups
749
750
751 Due to our Open real time publishing of the Libre-SOC project, our work
752 can be forked by anyone at any time as a starting point or as a building
753 block for new projects, potentially taking the ideas and concepts in any
754 direction. These can be individuals or teams and they can be academics
755 or industrialists, the point being that if we trigger a step change in
756 the technology everyone should be able to benefit.
757
758
759 This is in addition to our own commercialisation plans.
760
761
762 Open Source methodology leads to Open standards which leads to Open
763 understanding and rapid adoption of new ideas in academia and industry.
764 The Eurocentric nature and benefit of the work should not be overlooked
765 either.
766
767
768 ### Outcomes
769
770
771 As the development chain includes elements of commercialisation, beyond
772 the immediate benefit to similar projects by the enhancement of the
773 Libre/Open Source tool chain and the educational uplift provided directly
774 and by example to other groups and European businesses and Educational
775 Establishments planning Software-to-Silicon projects, the most direct
776 outcome will be the availability, as devices in the market through RED
777 Semiconductor Ltd, of a new concept in supercomputing power that is also
778 completely security auditable and transparent.
779
780
781 We are already aware of a commercial venture formed recently, who are
782 aware and already benefiting from our work over the last three years to
783 improve the Software-to-Silicon toolchain, that is now focusing on the
784 finessing of the toolchain and its human interface to widen access to the
785 methodology and IMEC are using our architectural test chip, currently in
786 production, to validate and test their new cloud based chip design suite.
787 The outcomes are already happening and are bound to magnify.
788
789
790 ### Impacts
791
792
793 We believe the market demand for our step change in core architecture
794 thinking is so great it will force the world's leading microprocessor
795 companies to follow. The result will be a greater step change in the
796 performance and security of computer hardware across the world.
797
798
799 Additionally the confirmation of Silicon-proven Cell Libraries and
800 a European-led functional Libre-Licensed VLSI toolchain in lower
801 geometries will significantly reduce the cost of ASIC development for
802 European businesses and reduce to zero the risk of critical dependence
803 on non-Sovereign (geo-politically constrained) Commercial VLSI tools
804 and Cell Libraries.

869 Objectives:
870
871
872 To manage the people who put in supplementary (by timescale) proposals
873 intended to support the core objectives of our proposal, ensuring that
874 those proposals also honour and meet the objectives outlined in the
875 original call:
876
877 https://ec.europa.eu/info/funding-tenders/opportunities/portal/screen/opportunities/topic-details/horizon-cl4-2021-digital-emerging-01-01
878
879
880 This will allow us to address and deploy new ideas and concepts not
881 immediately available to us at the time of this submission, and have
882 them properly vetted by an Organisation both familiar with our work,
883 and already trusted by the EU to fulfil the same role for other EU Grants.
884
885
886 Description of work:
887
888
889 These descriptions effectively mirror the light-weight grant mechanism
890 NLnet manages for the NGI research and development calls (EU Grants
891 825310 and 825322) and does not deviate from those pre-established
892 procedures except to define the context of the work to be carried out
893 by the Grant Recipient to fall within the criteria defined by this call
894 (HORIZON-CL4-2021-DIGITAL-EMERGING-01-01) not those of the previous Grants
895
896
897 * To include on the NLnet website a dedicated Call for mini-grant (EUR 50,000) Proposals, meeting the criteria of this existing Call (HORIZON-CL4-2021-DIGITAL-EMERGING-01-01) where the wording shall be written by NLnet and approved by the EU.
898 * To analyse and vet the Proposals to ensure that they match the criteria, through a multi-stage process including validating appropriateness to the Libre-SOC Project and running each application through an Independent Review by the EU.
899 * To notify successful Applicants, to ensure that they sign a Memorandum of Understanding with attached pre-agreed Milestones, and to fulfil Requests for Payment on 100% successful completion of those same pre-agreed Milestones.
900 * To produce Audit and Transparency Reports and to engage the services of Auditors to ensure compliance.
901
902
903 Deliverables:
904
905
906 Again these deliverables are no different from NLnet's existing
907 deliverables to the EU under Grant Agreements 825310 and 825322
908
909
910 * 1.1. A functioning Call-for-Proposals on the NLnet website.
911 * 1.2. Inclusion of the new CfP within the existing NLnet infrastructure
912 * 1.3. Progress Reports and Independent Audit Reports to the EU

937 by the OPF ISA WG within their Request For Change (RFC) Process, and to
938 deliver them.
939
940
941 Description of work:
942
943
944 * Extend Draft SVP64 into other areas necessary for fulfilment of this Call (including Zero-Overhead Loop Control)
945 * Prepare SVP64 Standards Documentation for RFC Submission, including identifying appropriate subdivisions of work.
946 * Create presentations and explanatory material for OpenPOWER Foundation ISA WG Members to help with their Review Process
947 * Complete OPF ISA WG RFC submission requirements and submit the RFCs (Note: Compliance Test Suites are also required but are part of Work Package 3)
948 * Publish the results of the decision by the ISA WG (whether accepted or not) and adapt to feedback if necessary
949 * Repeat for all portions of all SVP64 Standards.
950
951
952 Deliverables:
953
954
955 Note: some of these deliverables may not yet be determined due to
956 the OpenPOWER Foundation having not yet finalised and published its
957 procedures, having not yet completed their Legal Review. In addition,
958 although we can advise and consult with them, it will be the OPF ISA
959 WG who decides what final subdivisions of SVP64 are appropriate (not
960 the Participants). This directly impacts and determines what the actual
961 Deliverables will be: They will however fit the following template:
962
963
964 * 2.1. Publish report on appropriate subdivisions of SVP64 subdivisions into multiple distinct OPF RFCs
965 * 2.2. Publish presentations and explanatory materials to aid in the understanding of SVP64 and its value
966 * 2.3. Attend Conferences to promote SVP64 and its benefits
967 * 2.4. Complete the documentation and all tasks required for each SVP64 RFC and submit them to the OPF
968 * 2.5. For each RFC, publish a report on the decision and all other permitted information that does not fall within the Commercial Confidentiality Requirements set by the OpenPOWER Foundation (these conditions are outside of our control).

1255 Objectives:
1256
1257
1258 To improve coriolis2 for lower geometries (to be decided on evaluation)
1259 such that it performs 100% DRC-clean (Design Rule Check) GDS-II files
1260 at the chosen geometry for the chosen Foundry, for each ASIC.
1261
1262
1263 Note: Commercial "DRC" will confirm that the GDS-II layout meets timing,
1264 electrical characteristics, ESD, spacing between tracks, sizes of vias
1265 etc. and confirms that the layout will not damage the Foundry's equipment
1266 during Manufacture.
1267
1268
1269 Description of work:
1270
1271
1272 Please Note: Work Packages 7, 8 and 9 are highly interdependent and
1273 will cross fertilise their results in an iterative manner as the design
1274 complexity increases, starting from smaller rapid-prototype test ASIC
1275 layouts and progressing to full designs.
1276
1277
1278 * The main focus (absolute priority) should be put on timing closure
1279 that becomes critical in the lower nodes. And if we can only achieve
1280 this alone, it will be a great success. That entails:
1281 - Improve the clock tree (change from H-Tree to a dynamically
1282 balanced one).
1283 - Improve High Fanout Net Synthesis.
1284 - Prevent hold violations.
1285 - Resizing of the gates (adjust power).
1286 - Logical resynthesis along the critical path, if needed.
1287 - Add a whole timing graph infrastructure.
1288 * To be able to implement those features has deep consequences on P&R:
1289 - We must have an "estimator" of the timing in the wires
1290 (first guess: Elmore).
1291 - The placer algorithm SimPL needs to be upgraded/rewritten
1292 to take on more additional constraints (adding and resizing
1293 gates on the fly).
1294 * Better power supply. Control of IR-drop.
1295 * Protection against cross-coupling.
1296 * During all that process, we must work on a stable database.
1297 So correct speed bottleneck only in algorithms built upon it,
1298 not the DB itself. For this kind of design, it is acceptable
1299 to run a full day on a high end computer.
1300 * Start a parallel project about to redesign the database (providing a backward
1301 compatibility API to Hurricane). But we must not make depend the timing closure
1302 on the database Rewrite.
1303
1304
1305 Deliverables:
1306
1307
1308 The key deliverables are measured by the successful passing of DRC
1309 (Design Rule Checks) against Commercial VLSI tools (Mentor, Synopsis), and
1310 is so critically inter-dependent on all components working 100% together
1311 that there can only be one deliverable, here, per ASIC Layout. Completion
1312 of sub- and sub-sub-tasks shall however be recorded in an easily-auditable
1313 Standard Libre/Open Task Tracking Database (gitlab, bugzilla) and
1314 appropriate structured progress reports created. As is the case with
1315 all Libre/Open Projects, "continuous" delivery is inherent through the
1316 ongoing publication of all source code in real-time. Full delivery is
1317 expected around 30 months.

1350 and to test the resultant ASICs. This to confirm that the advancements
1351 to the entire coriolis2 VLSI Toolchain is in fact capable of correctly
1352 producing ASICs at both smaller geometries than it can already do,
1353 and at much larger sizes than it can already handle. To publish reports
1354 that serve to inform European Businesses and Academic Institutions of
1355 the results such that, if successful, those Businesses will potentially
1356 save hugely on the cost of development of ASICs, and the dependence
1357 on geo-political commercial tools is mitigated and the EU's Digital

1572
1573 These are the subcontracting costs for the participants
1574

1587 |4790000 | total |
1588
1589 (1) These software and compiler costs are to develop extremely specialist
1590 software, where it is Industry-standard normal to spend EUR 25 million
1591 to achieve TRL (9). Contracting of an extremely small pool of specialist
1592 Companies (Embecosm Gmbh, Vrull.EU) is therefore Industry-standard normal
1593 practice. All of the Compiler / Software Contracting shall be with
1594 Companies that are part of the European Union.
1595
1596 (2) IMEC is one of Europe's leading Sub-contractors for ASIC MPW Shuttle
1597 runs, and they handle the NDA relationships with Foundries that are almost
1598 impossible to otherwise establish.

1662 # 3.2 Capacity of participants and consortium as a whole
1663
1664
1665 The majority of the consortium have been working together for over
1666 three years on the precursor technical development of the Libre-SOC core
1667 project, the evolution of which is the lynch-pin and "proving-ground"
1668 of this grant application. The public record of their achievements
1669 and team involvement can be found in their public Open Source record
1670 https://libre-soc.org/.
1671
1672 The Libre-SOC team are internationally experienced software professionals
1673 who have strong familiarity with state of the art software to silicon
1674 technologies. They have been supported by two of the co-applicants labs
1675 CNRS and LIP6 (The applicants being Sorbonne Université and Affiliated
1676 Entity, CNRS), and many other European based technology development
1677 groups, which each provide key elements of the project from specialist
1678 programs such as coriolis2, alliance, HITAS, YAGLE and more, and the
1679 manufacturing expertise of Imec. Their versatility and experience with
1680 Libre/Open Source Software also means that they can adapt to unforeseen
1681 circumstances and can navigate the ever-changing and constantly-evolving
1682 FOSS landscape with confidence.
1683
1684 The above is critically important in light of the requirement to
1685 demonstrate access to critical infrastructure, resources and the
1686 ability to fulfil: with the sole exception of NDA'd Foundry PDKs
1687 (Physical Design Kits), the entirety of this project is Libre/Open
1688 Source, both in the tools it utilises, components that it uses, and
1689 the results that are generated. With there being no restriction on
1690 the availability of Libre/Open Source software needed to complete the
1691 project, the Participants correspondingly have no impediment. We also
1692 have a proven strategy to deal with the NDA's: a "parallel track" where
1693 at least one Participant (Sorbonne Université, LIP6 Lab) has signed
1694 TSMC Foundry NDAs, and consequently there is no impediment there, either.
1695
1696 Sorbonne Université (SU) is a multidisciplinary, research-intensive
1697 and world class academic institution. It was created on January 1st
1698 2018 as the merger of two first-class research intensive universities,
1699 UPMC (University Pierre and Marie Curie) and Paris-Sorbonne. Sorbonne
1700 Université is now organized with three faculties: humanities, medicine
1701 and science each with the wide-ranging autonomy necessary to conduct
1702 its ambitious programs in both research and education. SU counts 53,500
1703 students, 3,400 professor-researchers and 3,600 administrative and
1704 technical staff members. SU is intensively engaged in European research
1705 projects (163 FP7 projects and 195 H2020 projects). Its computer
1706 science laboratory, LIP6, is internationally recognized as a leading
1707 research institute.
1708
1709 LIP6 is a Joint Research Unit of both SU (Sorbonne Université)
1710 and CNRS. Both entities invest resources within LIP6 so CNRS is then
1711 an Affiliated Entity linked to SU. According to SU-CNRS agreement
1712 regarding LIP6, SU, as a full partner, manages the grant for its
1713 Affiliated Entity, CNRS.
1714
1715 RED Semiconductor Ltd has been established as a commercialisation vehicle,
1716 sharing the Libre principles of the core Libre-SOC team and bringing
1717 Semiconductor industry commercial management and technology experience.
1718 This includes the founders of two successful semiconductor companies
1719 and a public company chairman. There is also a cross directorship of
1720 Luke Leighton (of Libre-SOC) giving the company an extensive technology
1721 market and leadership experience.
1722
1723 NLnet is a Netherlands based public benefit organisation that brings
1724 to the table over 35 years of European internet history and well over
1725 two decades of unique real-world experience in funding and supporting
1726 bottom up internet infrastructure projects around the world - engaging
1727 some of the best independent researchers and developers. NLnet has
1728 funded essential work on important infrastructure parts of the internet,
1729 from the technologies with which the answers from the DNS root of the
1730 internet can now be trusted, all the way up to key standards for email
1731 security, transport layer security, email authenticity, and a lot more
1732 - on virtually every layer of the internet, from securing core routing
1733 protocols to browser security plugins, from firmware security to open
1734 source LTE networks.
1735
1736 Most recently NLnet is hosting the NGI0 Discovery, NGI0 PET and NGI
1737 Assure open calls as part of the Next Generation Internet research and
1738 development initiative, of which NLnet supports 300+ open source software,
1739 open hardware and open standards projects to build a more resilient,
1740 sustainable and trustworthy internet.
1741
1742 NLnet, a Stichting / Foundation, has been Libre-SOC’s funding source
1743 from the beginning and fundamentally understands our technology and
1744 direction of travel. As well as providing augmentation under existing
1745 EU Grants funding for technology opportunities that we will benefit from
1746 but are yet to be identified, they are a fundamental sounding board that
1747 will be invaluable to the project moving forward.
1748
1749 Helix develops antennas and electronic systems for PNT (Position,
1750 Navigation, Timing) applications. Markets include defence/security,
1751 asset tracking, autonomous systems/vehicles/drones/robotics, critical
1752 infrastructure (network sync – 5G, V2X, etc), fintech (blockchain
1753 timestamping) and many other industrial applications.
1754
1755 Helix solutions defend against the vulnerabilities and threats to
1756 global dependency on GNSS (Global Navigation Satellite Systems), where
1757 disruption to services would cost the world’s major economies £10s
1758 of Billions every single day. Our patented technology enables filtering
1759 antennas to mitigate multi-path, RF and electrical interference and
1760 reduce the impact of jamming and spoofing, meaning that the receiver
1761 electronics becomes a streamlined high performance, low-power/low-cost
1762 correlator/processor to deliver highly accurate and resilience x,y,z
1763 and time data as its output. We are developing sophisticated anti-
1764 jamming/spoofing hardware that uses targeted nulling to ignore jamming,
1765 and enable system-level resilience. This capability can be co-designed
1766 with the receiver chipset for ultimate resilience.
1767
1768 Regarding the extreme high-end computing resources necessary to complete
1769 the exceptionally-demanding task of VLSI development and Layout, we
1770 find that high-end modern laptops and desktop computers (with 64 to
1771 256 GB of RAM) are perfectly adequate. However in the event that our
1772 immediately-accessible computing resources are not adequate, both Sorbonne
1773 Université (LIP6 and CNRS) and Libre-SOC qualify for access to Fed4Fire
1774 (https://www.fed4fire.eu/- grant agreement No 732638) which gives us
1775 direct access to large clusters (100+) high-end servers. Additionally,
1776 we are specifying some of these high-end computers in our budget, and
1777 the software to run on them is entirely Libre-Licensed and within our
1778 combined experience to deploy.
1779
1780 We have established that Embecosm Gmbh and Vrull.eu are some of the
1781 world's leading experts in Compiler Technology. We will put out to
1782 tender a Contract with an initial evaluation phase, followed by a TRL
1783 4/5 Research phase for the prerequisite compilers (gcc, llvm, Kazan,
1784 MESA3D) necessary to support the core design work.
1785
1786 The OpenPOWER Foundation is a part of the Linux Foundation,
1787 and is directly responsible for the long-term protection
1788 and evolution of the Power ISA. Members include IBM, Google,
1789 NVidia, Raptor Engineering, University of Oregon and many more.
1790 https://openpowerfoundation.org/membership/current-members/.
1791
1792 The Chair of the newly-formed ISA Working Group is Paul Mackerras, and
1793 the Technical Chair is Toshaan Bharvani. Both of these people have
1794 been kindly attending bi-weekly meetings with the Libre-SOC Team for
1795 over 18 months, and we have kept them apprised of ongoing developments,
1796 particularly with the Draft SVP64 ISA Extension. They are both going
1797 out of their way to regularly advise us on how to go about a successful
1798 RFC Process for SVP64, and we deeply appreciate their support.
1799
1800 Helix Technology's involvement, as a potential customer and potential
1801 user of the Libre-SOC technology, will give focus to the deliverable of
1802 the project. They have world-leading expertise in Antenna Technology,
1803 and in the mathematics behind the Signal Processing required for
1804 GNSS/GPS. We have deliberately selected them to ensure the ambition of
1805 our overall project.
1806
1807 We therefore have a cohesive cooperative team of experience from concept
1808 to customer product and a supporting cast of specialist technical support
1809 that are an established practiced team.
1810
1811 As a last point: the creation of the teams for this project is critical
1812 for RED Semiconductors Limited and Libre-SOC. We have the benefit of
1813 having the core of an International Technology Headhunter Research
1814 Team amongst the directors of RED Semiconductor Limited, giving us
1815 the capability to ensure the project is fully manned in the required
1816 timescales without the need to externally resource recruitment services,
1817 and this is included in RED’s management manpower.
1818
