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

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, LIP6 and CNRS will need to
204 create smaller geometry ports of FlexLib. These Cell Libraries need to
205 be tested in actual Silicon, and consequently we will be working with
206 IMEC as a sub-contractor and partner to deliver MPW Shuttle Runs for
207 these critical Libraries, using Libre-SOC Cores as a "proving-ground".
208

210
211
212 In addition, NLnet, a Stichting / Foundation, has been so successful
213 in supporting "Works for the Public Good" that we feel that their approach
214 and service fulfilment are extremely relevant to this Call. During the
215 36 month duration of the proposal, NLnet is in a position to engage
216 with Libre/Open Hardware and Software developers which, for our team,
217 will mitigate the risk of unanticipated issues requiring specialist but
218 small-scope funding, that yet still meets the well-defined objectives
219 of this Call.
220
221 To put all of this to practical use, Helix Technologies, by defining
222 an advanced GPS Correlator, will set a Computational capability objective
223 for the core technology and be a Reference test-bed. Helix will then
224 be able to carry out the comparative studies which show that the core
225 technology meets significant performance/watt improvements. The ultimate
226 destination for some of these devices will be Satellites (Space).
227
228 Summary of why our work is pertinent to Call HORIZON-CL4-2021-DIGITAL-EMERGING-01-01:
229
230
231 * 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.
232 * 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".
233 * 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.
234 * 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.
235 * 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.
236 * 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.
237 * 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.
238
239
240 Additional notes:
241
242
243 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.
244 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 ## 1.2 Methodology
256
257
258 * 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.
259 * LIP6 likewise discloses all source code at https://gitlab.lip6.fr/vlsi-eda
260 * LIP6's toolkit containing existing large-geometry Cell Libraries and test benches at https://gitlab.lip6.fr/vlsi-eda/alliance-check-toolkit.
261 * CNRS's HITAS/YAGLE is also Open Source https://www-soc.lip6.fr/equipe-cian/logiciels/tasyagle/.
262 * Symbiyosys and its subcomponents for Formal Correctness Proofs are Libre/Open https://symbiyosys.readthedocs.io/.
263 * GPS GNSS-SDR is also Open Source https://gnss-sdr.org/ and can be adapted for Helix's requirement
264 * Chips4Makers FlexLib is also Open Source https://gitlab.com/Chips4Makers but the NDA'd "ports" are not.
265 * 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.
266
267
268 This methodology is based on an established process that has already
269 allowed us to deliver demonstrable software and hardware results,
270 the manifestation of which is our 180nm architecture test chip now
271 in manufacture. This has involved a significant amount of cooperative
272 development among the applicants, and others beyond, and the development
273 of core supporting technology that this grant application can now
274 efficiently build upon.
275
276
277 We refer to other supporting technology sources further in this
278 application and whilst they are not the core team they will critically
279 contribute to the overall success. In particular, these groups can be
280 supported by NLnet, whose "Works for the Public Good" remit is 100%
281 compatible with the full transparency objectives (that the project's
282 participants are already committed to) which will help by providing
283 additional non-core-team development on an on-demand basis, on the back
284 of NLnet's already-trusted commitment to fulfil European Union objectives
285 under Grant Agreements No 825310 and 825322.
286
287
288 Additionally, Libre-SOC is working closely with the OpenPOWER Foundation
289 ISA Working Group Chair, having attended regular bi-weekly meetings for
290 over 18 months. As mentioned above, the entirety of our work of greater
291 than 3 years on this Vector Extension, SVP64, is entirely transparent
292 and open: https://libre-soc.org/openpower/sv/svp64/. Both NLnet
293 (and StandICT.eu through a proposal under consideration at the time of
294 writing) are supporting our efforts to submit the Draft SVP64 and its
295 subcomponents through the RFC (Request for Change) process being developed
296 by the OpenPOWER Foundation. For long-term stability and impact it is a
297 necessary prerequisite that Draft SVP64 become an official part of the
298 Power ISA: this decision is however down to the OpenPOWER Foundation
299 and requires considerable preparation and planning, which this Grant
300 will help support.
301
302
303 One huge benefit of Libre-SOC's core being Power ISA 3.0 Compliant is that
304 IBM contributed a huge patent pool through the OpenPOWER EULA. Compliant
305 Designs enjoy the protection of this patent pool. By contributing SVP64
306 to the Power ISA it falls under this same umbrella. Libre-SOC shall be
307 entering into an agreement with the OpenPOWER Foundation, here, as part
308 of the ISA RFC process. European businesses clearly benefit from the
309 long-term stability of this arrangement.
310
311
312 Whilst we clearly need, ultimately, to prove our design's power-efficiency
313 in silicon, we would however consider it unwise and extremely costly to
314 tape-out to Silicon without having gone through a proper early-evaluation
315 process, weeding out ineffective strategies and designs. To that end, we
316 learned from Jeff Bush's work on the Nyuzi 3D core to perform estimates
317 on power consumption and clock cycles. This is a highly-effective
318 feedback process that allows identification and targeting of the most
319 urgent (inefficient) areas, and we have taken it on-board and adopted
320 it throughout the project.
321
322
323 Part of that involves Peter Hsu's cavatools (another NLnet Grant) which
324 is (at present) a cycle-accurate Simulator for RISC-V. A (new) NLnet
325 Grant (not yet approved at the time of writing) is targeted at porting
326 cavatools to the Power ISA. This proposal would allow NLnet-funded work to
327 be extended into 3D, Video, DSP and other areas, to simulate (test) out
328 the feasibility, power-efficiency and effectiveness of different Custom
329 SVP64 Extensions to the Power ISA, long before they reach actual Silicon.
330
331
332 # 2 Impact
333
334
335 ## 2.1 Project’s pathways towards impact
336
337
338 The core of modern computing is the capability of the computational
339 element of the systems and the microprocessors they are based around.
340 Every twenty years there has been a significant evolutionary step in the
341 technical concepts employed by these microprocessor devices. For example
342 the last big step was the concept of RISC (Reduced Instruction Set)
343 processors. These developments have been driven by many forces from
344 cost of devices to limitations of the available technology of the time.
345
346
347 The Libre-SOC core is capable of becoming the next significant step
348 change in microprocessor speed, technology, and reduction in equivalent
349 computational power (Watts).
350
351
352 To illustrate this, we need to go back in history to early computing.
353 The first microprocessors were reliant on expensive core then bipolar
354 memory and even with the advent of DRAMS (Dynamic Random-Access Memories)
355 the primary focus of microprocessor processor core designs was to
356 optimise the minimal use of memory and focus on the power of the core.
357 Over time, memory became cheaper and reliance on memory to improve
358 processing increased with techniques like RAMdisk stores were developed.
359 This cheap memory also resulted in the evolution of RISC and similar
360 computing technology concepts. Today the problem is epitomized by speed,
361 where microprocessors have evolved to be much faster than the fastest
362 memories, and to increase performance, the state of the art computing
363 requires coming full-circle: once again minimising the use of memory,
364 which is now a log jam, and looking again at the core optimisation
365 solutions devised in the 1960’s by luminaries such as Seymour Cray.
366 The Libre-SOC core is an optimal adoption of this category of core
367 processor performance enhancement.
368
369
370 Libre-SOC has the benefit that its development relies on fundamental
371 research that has been known and proven for nearly 60 years. SVP64 has
372 input from and takes on-board lessons learned from NEC SX-Aurora, Cray-I,
373 Mitch Alsup's MyISA 66000, RISC-V RVV Vectors, MRISC32, AVX-512, ARM
374 SVE2, Qualcomm Hexagon and TI's DSP range, as well as other more esoteric
375 Micro-architectures such as Aspex's Array-String Processor and Elixent's
376 2D Grid design.
377
378
379 As a Hybrid (merged) CPU-VPU-GPU Micro-architecture (similar to
380 ICubeCorp's IC3128) there is a huge reduction in the complexity
381 of 3D Graphics and Video Driver and overall hardware. NVidia, ARM
382 (MALI), AMD, PowerVR, Vivante: these are all dual (ISA-incompatible)
383 architectures with staggering levels of hardware-software complexity.
384 Like ICubeCorp's design, Libre-SOC 3D and Video binaries are executed
385 directly on the actual main (one) core.
386
387
388 The end-result here is, if deployed in mass-volume products world-wide
389 including for European end-users of ubiquitous Computing devices, a
390 significant energy saving results on a massive scale, particularly in
391 battery-operated (mobile, tablet, laptop) appliances. Demonstrating this
392 however requires, ultimately, that we actually create real silicon,
393 and measure its performance and power consumption.
394
395
396 ## 2.2 Measures to maximise impact - Dissemination,
397 exploitation and communication
398
399
400 As the Libre-SOC core is the result of a Libre/Open Source project
401 by default all of our development work has been published for the last
402 four years. This was also a requirement of our EU funding through NLnet.
403 In addition we have undertaken a full program of conference presentations,
404 technology awareness activities and cooperation with key bodies such as
405 the OpenPOWER Foundation and OpenPOWER Members (Libre-SOC is participating
406 in a world-wide Open University Course about the OpenPOWER ISA, an
407 activity led by IBM). Examples:

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

443
444 ## 2.3 Summary
445
446
447 ### Specific needs
448
449
450 Modern computing technology is designed in secrecy and released to
451 the market without the ability of the user base to vet or validate.
452 When problems arise it is usually due to “discovery” and usually
453 driven by technical curiosity or malice. What is clear is that to those
454 on the inside these problems were visible from the outset, however
455 time resource and unwillingness to explore (and unethical Commercial
456 pragmatism) has left these vulnerabilities open to be exploited. As a
457 general principle we have taken the view that any new design should be
458 open to review and able to be corrected (every design has some bugs)
459 before mass adoption and the inevitable loss and crisis.
460
461
462 In practical terms: as indicated in sections above there have
463 been a number of security incidents involving ubiquitous computing
464 devices, impacting millions to hundreds of millions of end-users,
465 world-wide. Qualcomm failed last year to provide adequate secure firmware,
466 leaving 40% of the entire world's Android smartphones vulnerable to
467 attack. With the majority of smartphones being "fire-and-forget" products
468 with non-upgradeable firmware, the end-user's only solution is to throw
469 away a perfectly good electronics product and purchase a new one.
470 For Intel products - all Intel products - the exact same thing has
471 occurred (Master Firmware Key, Spectre, Meltdown), but at an unfixable
472 hardware level, and there are no replacement Intel products that can be
473 purchased in the market to "fix" their fundamental design flaws.
474
475
476 Not only that, but all of the ubiquitous Computing products (Apple, Intel,
477 IBM, NVidia, AMD being the most well-known) are 100% non-EU-based. As far
478 as EU Digital Sovereignty is concerned, this is an extremely serious
479 and alarming situation, compounded by critical Foundries and know-how
480 to run those Foundries also not being part of a Sovereign European remit.
481
482
483 If that was not enough, Foundries and the Semiconductor Industry requires
484 NDAs that at the minimum prohibit full publication of Academic results,
485 stifling innovation and research, in turn driving up the cost for EU
486 businesses of the cost of ASIC products by creating artificial cost,
487 overhead and knowledge barriers.
488
489
490 The entire Computing and Semiconductor Industry needs a new approach.
491
492
493 Taking the initiative, the end goal of the Libre-SOC/RED Semiconductor
494 Ltd project is therefore to deliver high performance, security auditable,
495 supercomputer class computing devices to the market. As this is not
496 currently available it will prompt a step change in low power (Watts)
497 high performance computing. This will be achieved through:
498
499
500 * Energy/Power consumption measurement: we need to verify that performance/watt is lowered
501 * Draft SVP64 inclusion in Power ISA: this is needed to indicate "Official long-term Status"
502 * Auditability and Transparency: needed for end-users and EU businesses to trust the hardware.
503 * Power ISA 3.0 Interoperability: to leverage over 2 decades of existing business software tools.
504 * FPGA and Simulator demonstrators: to demonstrate feasibility of the HDL and the ISA
505 * VLSI toolchain and Cell Library: MPW Shuttle runs are needed to reach "Silicon-proven" status
506 * NLnet mini-grants: Effectively this is a "Reserve" budget for the Project, managed by NLnet
507
508
509 ### Dissemination, exploitation and Communication
510
511 Energy/Power consumption measurement:
512
513
514 Just as Jeff Bush showed by publishing Nyuzi Research at Conferences we
515 shall follow the same proven incremental performance/watt measures and
516 procedures, and publish the results.
517
518 https://ieeexplore.ieee.org/document/7095803/
519
520
521 Draft SVP64 inclusion in Power ISA:
522
523
524 We are already working with the OpenPOWER ISA Working Group, and have
525 already begun publishing the Draft SVP64 Specification as it is being
526 developed. This will become official RFCs (Request for Changes) leading
527 to adoption. This includes development of Compliance Test Suites,
528 low-level libraries, compilers etc. which shall be announced through
529 Conferences, Press Releases (by RED Semiconductor Ltd, NLnet and the
530 OpenPOWER Foundation) and standard Libre/Open development practices
531 (Mailing list Announcements).
532
533
534 Auditability and Transparency:
535
536
537 Using symbiyosys we have already established a number of Formal
538 Correctness Proofs for the TRL 3 HDL used in the 180nm ASIC: This
539 needs to be extended right the way throughout all future work and be
540 published for other OpenPOWER Foundation Members and European businesses
541 to be able to independently verify the correct functionality of not just
542 Libre-SOC ASIC designs but other Power ISA 3.0 compliant designs as well.
543 Libre-SOC HDL and the associated Formal Correctness Proofs are published
544 as-they-are-developed in real-time and consequently dissemination is
545 implicit and automatic.
546
547
548 For the Silicon-level "EMF signature" measurement system Libre-SOC
549 will define and publish Reference Standards, test applications and
550 methodology documentation. RED Semiconductor Ltd will establish
551 and make available a "expected results" database for its commercial
552 products, as part of its Product Application Documentation, so that
553 European Businesses may independently verify that their commercial
554 off-the-shelf RED Semiconductor Ltd products have not been tampered with
555 at the Silicon level. (It is beyond the scope of this Grant however RED
556 Semiconductor Ltd will publish its overall Quality Standards Strategy).
557 In concept, the "EMF Signature" strategy is very similar to Hewlett
558 Packard's "Signature Analysis Strategy" that has been around since
559 1949. https://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1977-05.pdf
560
561
562 Power ISA 3.0 Interoperability:
563
564
565 Standing on the shoulders of Giants (IBM and other OPF Members in
566 this case) is always a good starting point. The familiarity and
567 decades-long-term stability of the existing Power ISA 3.0 gives us a vast
568 existing-established user audience to whom we can provide training and
569 experience upgrades from an existing high-level of knowledge. In this
570 we already have the cooperation of IBM (through the OpenPOWER University
571 Education Course that Libre-SOC has helped to create - to be first run
572 from 18th-29th October 2021).
573
574
575 We will take the Interoperability further at a practical level
576 by developing a Libre/Open Power ISA 3.0 "Compliance Test
577 Suite" that meets the OpenPOWER Foundation documented standards
578 (https://openpowerfoundation.org/openpower-isa-compliance-definition/)
579 and make it entirely public and available to all without limit, and invite
580 other OpenPOWER Foundation Members to participate in its development
581 and use. This will then be, again, announced through Press Releases
582 and Mailing List as well as Conference Presentations.
583
584
585 FPGA and Simulator demonstrators:
586
587
588 Again: all new software tools created, and existing ones used and modified
589 to both develop and use resultant devices will be published as an inherent
590 part of the OpenSource real time publishing strategy.
591
592
593 VLSI Toolchain and Cell Library verification:
594
595
596 Again: the results of the development are, to date and in the future,
597 part of Libre/Open Source projects, and are therefore fully-visible, even
598 though they are Hardware-related we treat them as Open Source Software.
599 Conference presentations shall therefore be given, announcements on
600 Mailing Lists, as part of the overall communications strategy.
601
602
603 In this particular case however, the communication has to involve the
604 results of the MPW Shuttle runs, testing the actual ASICs, because it
605 is critical to demonstrate and communicate that the Cell Libraries are
606 Silicon-Proven and that the VLSI tools were capable of successfully
607 creating that Silicon-Proven layout. However the caveat here: anything
608 involving NDA'd material as required by the Foundry has to remain
609 confidential (note that this is not something that can be addressed
610 within the funding scope of this Call)
611
612
613 NLnet mini-grants:
614
615
616 NLnet's website has already been established with communication facilities
617 for around 19 years. NLnet are experienced in the effective evaluation
618 and management of small-scale Grants. They are also extremely familiar
619 with the work that we are doing, and with the detail of EU Grant
620 Procedures. Following those procedures they will add a new section to
621 the website for Grant Proposals that inherently meet the objectives of
622 this Call, and will use their existing communications infrastructure to
623 maximum benefit.
624
625
626 ### Expected results
627
628
629 Energy/Power consumption measurement:
630
631
632 We anticipate in the actual ASIC a significant measurable reduction in
633 performance/watt. Early predictions shall be based on Instruction-level
634 Simulations, but these need to be validated against the "real thing".
635 Due to the iterative process (outlined by Jeff Bush) we simply cannot
636 state exactly in advance the full magnitude of improvement that will
637 occur. The process itself, and how it was successfully applied, however,
638 will be considered to be part of the results themselves as part of
639 publications online and at Conferences.
640
641
642 Draft SVP64 inclusion in Power ISA:
643
644
645 The ultimate outcome here is that SVP64 becomes an officially-adopted
646 part of the OpenPOWER ISA, including a full compliance test suite,
647 documentation in a future revision of the official Power ISA Technical
648 Reference Manual. This process is, however, by necessity and being an
649 extremely important responsibility of the OpenPOWER Foundation (not of
650 any of the Participants), very slow and outside of our control, and may
651 take longer than the 36 month duration of the Grant to complete.
652
653
654 Therefore, the critical Milestone shall be our submission to the
655 OpenPOWER Foundation's ISA Working Group, as well as the development of
656 the required Compliance Test Suites. Both of these shall be published
657 under appropriate Libre/Open Licenses.
658
659
660 Auditability and Transparency:
661
662
663 We will have completed the Formal Correctness Proofs and published them
664 and the results of running them against the Libre-SOC HDL. We will also
665 have received the ASICs back from MPW Shuttle runs, which will contain
666 "EMF detection" wires routed strategically throughout it, and run the
667 pre-arranged unit tests that will create "Signatures" that shall be
668 recorded and published. This task is another critical reason why we
669 need actual Silicon, because only with an ASIC can we demonstrate the
670 viability of Signature Analysis (and similar) Strategies for ASICs.
671
672
673 Power ISA 3.0 Interoperability:
674
675
676 We will have completed an implementation of the Compliance Test
677 Suite as a Libre-Licensed application that can test multiple different
678 implementations: FPGA, Simulators (including our own as well as qemu), and
679 actual Silicon implementations including IBM POWER9, POWER10, Microwatt.
680 In addition we will have extended our own interoperability "Test API"
681 that allows comparisons of any arbitrary user-generated application
682 against any other arbitrary Power ISA compliant devices (whether FPGA,
683 Simulator, or Silicon): the OpenPOWER Compliance Test Suite implementation
684 shall simply be one of those applications.
685
686
687 We expect the Libre-SOC core to pass the full OpenPOWER ISA 3.0 Test
688 Suite, and the results to be published. We will also communicate with
689 OpenPOWER Foundation Members and make them aware of the existence of
690 the Test Suite and document how it may be used to test their own Power
691 ISA 3.0 implementations for Compliance.
692
693
694 FPGA and Simulator demonstrators:
695
696
697 Successful software simulation (emulation) of the augmented Power 3.0 ISA
698 with the Draft SVP64 Extensions, and successful demonstration of the HDL
699 of a multi-core SMP processor implementing the same, running in a large
700 FPGA (the size of the commercially-available FPGAs constraining what
701 is possible, here). Each shall help verify the other's correctness.
702 This will be a rapid iterative cycle of development and shall always
703 produce early results, feeding back to continued improvement.
704
705
706 VLSI Toolchain and Cell Library verification:
707
708
709 Multiple demonstrator 2-core ASICs and a proven path to an 8-core ASIC
710 (as we anticipate that the 8-core is likely to be beyond the scope of the
711 Grant due to Silicon costs). Where the 2-core ASIC MPW is multi-purpose
712 (proving the HDL, proving the VLSI toolchain, proving the Cell Library)
713 and shall use the FPGA and Simulations to check its correctness before
714 proceeding, the 8-core shall remain in FPGA only, due to cost, but a
715 VLSI Layout for the 8-core will still be attempted, in order to "test
716 the limits" of the VLSI tools. If funding was available we could take
717 the 8-core to full MPW rather than just to FPGA and GDS-II. As the 8
718 core Layout develops, if it (and the coriolis2 toolchain) progresses
719 to viability in the 36 months one option might be for RED Semiconductor
720 to apply for a EUR 500,000 NLnet mini-grant, payment terms to meet
721 requirements set by IMEC, from their budget allocated under this proposal.
722
723
724 NLnet mini-grants:
725
726
727 NLnet will receive and review potentially hundreds of small Grant
728 Proposals to ensure that they meet both the Call's Objectives and meet
729 NLnet's responsibilities as a Stichting / Foundation to fund "Works
730 for the Public Good". They shall request that the successful Grant
731 Applicant create Milestones and that Grant Applicant communicate those
732 results, thus requiring that it is the Grant Applicant that fulfils the
733 requirement herein. This process is already established and already in
734 effect under Grant Agreements No 825310 and 825322.
735
736
737 In the case of the Participants, if we need "reserve" budgets for
738 unforseen activities, we commit to following that exact same procedure
739 and thus also shall meet the Objectives of this Call (examples include
740 the MPW 8-core, above). We are aware that new technology beneficial to
741 the project may not be currently apparent but will be available within
742 the 36 months duration, and the methodology of funding it through NLnet
743 may prove optimal and a cost-effective use of EU funds, as NLnet would
744 (as they do now) only draw the budget down as needed.
745
746
747 ### Target groups
748
749
750 Due to our Open real time publishing of the Libre-SOC project, our work
751 can be forked by anyone at any time as a starting point or as a building
752 block for new projects, potentially taking the ideas and concepts in any
753 direction. These can be individuals or teams and they can be academics
754 or industrialists, the point being that if we trigger a step change in
755 the technology everyone should be able to benefit.
756
757
758 This is in addition to our own commercialisation plans.
759
760
761 Open Source methodology leads to Open standards which leads to Open
762 understanding and rapid adoption of new ideas in academia and industry.
763 The Eurocentric nature and benefit of the work should not be overlooked
764 either.
765
766
767 ### Outcomes
768
769
770 As the development chain includes elements of commercialisation, beyond
771 the immediate benefit to similar projects by the enhancement of the
772 Libre/Open Source tool chain and the educational uplift provided directly
773 and by example to other groups and European businesses and Educational
774 Establishments planning Software-to-Silicon projects, the most direct
775 outcome will be the availability, as devices in the market through RED
776 Semiconductor Ltd, of a new concept in supercomputing power that is also
777 completely security auditable and transparent.
778
779
780 We are already aware of a commercial venture formed recently, who are
781 aware and already benefiting from our work over the last three years to
782 improve the Software-to-Silicon toolchain, that is now focusing on the
783 finessing of the toolchain and its human interface to widen access to the
784 methodology and IMEC are using our architectural test chip, currently in
785 production, to validate and test their new cloud based chip design suite.
786 The outcomes are already happening and are bound to magnify.
787
788
789 ### Impacts
790
791
792 We believe the market demand for our step change in core architecture
793 thinking is so great it will force the world's leading microprocessor
794 companies to follow. The result will be a greater step change in the
795 performance and security of computer hardware across the world.
796
797
798 Additionally the confirmation of Silicon-proven Cell Libraries and
799 a European-led functional Libre-Licensed VLSI toolchain in lower
800 geometries will significantly reduce the cost of ASIC development for
801 European businesses and reduce to zero the risk of critical dependence
802 on non-Sovereign (geo-politically constrained) Commercial VLSI tools
803 and Cell Libraries.

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

936 by the OPF ISA WG within their Request For Change (RFC) Process, and to
937 deliver them.
938
939
940 Description of work:
941
942
943 * Extend Draft SVP64 into other areas necessary for fulfilment of this Call (including Zero-Overhead Loop Control)
944 * Prepare SVP64 Standards Documentation for RFC Submission, including identifying appropriate subdivisions of work.
945 * Create presentations and explanatory material for OpenPOWER Foundation ISA WG Members to help with their Review Process
946 * 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)
947 * Publish the results of the decision by the ISA WG (whether accepted or not) and adapt to feedback if necessary
948 * Repeat for all portions of all SVP64 Standards.
949
950
951 Deliverables:
952
953
954 Note: some of these deliverables may not yet be determined due to
955 the OpenPOWER Foundation having not yet finalised and published its

957 although we can advise and consult with them, it will be the OPF ISA
958 WG who decides what final subdivisions of SVP64 are appropriate (not
959 the Participants). This directly impacts and determines what the actual
960 Deliverables will be: They will however fit the following template:
961
962
963 * 2.1. Publish report on appropriate subdivisions of SVP64 subdivisions into multiple distinct OPF RFCs
964 * 2.2. Publish presentations and explanatory materials to aid in the understanding of SVP64 and its value
965 * 2.3. Attend Conferences to promote SVP64 and its benefits
966 * 2.4. Complete the documentation and all tasks required for each SVP64 RFC and submit them to the OPF
967 * 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).

1254 Objectives:
1255
1256
1257 To improve coriolis2 for lower geometries (to be decided on evaluation)
1258 such that it performs 100% DRC-clean (Design Rule Check) GDS-II files
1259 at the chosen geometry for the chosen Foundry, for each ASIC.
1260
1261
1262 Note: Commercial "DRC" will confirm that the GDS-II layout meets timing,
1263 electrical characteristics, ESD, spacing between tracks, sizes of vias
1264 etc. and confirms that the layout will not damage the Foundry's equipment
1265 during Manufacture.
1266
1267
1268 Description of work:
1269
1270
1271 Please Note: Work Packages 7, 8 and 9 are highly interdependent and
1272 will cross fertilise their results in an iterative manner as the design
1273 complexity increases, starting from smaller rapid-prototype test ASIC
1274 layouts and progressing to full designs.
1275
1276
1277 * The main focus (absolute priority) should be put on timing closure
1278 that becomes critical in the lower nodes. And if we can only achieve
1279 this alone, it will be a great success. That entails:
1280 - Improve the clock tree (change from H-Tree to a dynamically
1281 balanced one).
1282 - Improve High Fanout Net Synthesis.
1283 - Prevent hold violations.
1284 - Resizing of the gates (adjust power).
1285 - Logical resynthesis along the critical path, if needed.
1286 - Add a whole timing graph infrastructure.
1287 * To be able to implement those features has deep consequences on P&R:
1288 - We must have an "estimator" of the timing in the wires
1289 (first guess: Elmore).
1290 - The placer algorithm SimPL needs to be upgraded/rewritten
1291 to take on more additional constraints (adding and resizing
1292 gates on the fly).
1293 * Better power supply. Control of IR-drop.
1294 * Protection against cross-coupling.
1295 * During all that process, we must work on a stable database.
1296 So correct speed bottleneck only in algorithms built upon it,
1297 not the DB itself. For this kind of design, it is acceptable
1298 to run a full day on a high end computer.
1299 * Start a parallel project about to redesign the database (providing a backward
1300 compatibility API to Hurricane). But we must not make depend the timing closure
1301 on the database Rewrite.
1302
1303
1304 Deliverables:
1305
1306
1307 The key deliverables are measured by the successful passing of DRC
1308 (Design Rule Checks) against Commercial VLSI tools (Mentor, Synopsis), and
1309 is so critically inter-dependent on all components working 100% together
1310 that there can only be one deliverable, here, per ASIC Layout. Completion
1311 of sub- and sub-sub-tasks shall however be recorded in an easily-auditable
1312 Standard Libre/Open Task Tracking Database (gitlab, bugzilla) and
1313 appropriate structured progress reports created. As is the case with
1314 all Libre/Open Projects, "continuous" delivery is inherent through the
1315 ongoing publication of all source code in real-time. Full delivery is
1316 expected around 30 months.
1317

1349 and to test the resultant ASICs. This to confirm that the advancements
1350 to the entire coriolis2 VLSI Toolchain is in fact capable of correctly
1351 producing ASICs at both smaller geometries than it can already do,
1352 and at much larger sizes than it can already handle. To publish reports
1353 that serve to inform European Businesses and Academic Institutions of
1354 the results such that, if successful, those Businesses will potentially
1355 save hugely on the cost of development of ASICs, and the dependence
1356 on geo-political commercial tools is mitigated and the EU's Digital

1572 These are the subcontracting costs for the participants
1573

1586 |4790000 | total |
1587
1588 (1) These software and compiler costs are to develop extremely specialist
1589 software, where it is Industry-standard normal to spend EUR 25 million
1590 to achieve TRL (9). Contracting of an extremely small pool of specialist
1591 Companies (Embecosm Gmbh, Vrull.EU) is therefore Industry-standard normal
1592 practice. All of the Compiler / Software Contracting shall be with
1593 Companies that are part of the European Union.
1594
1595 (2) IMEC is one of Europe's leading Sub-contractors for ASIC MPW Shuttle
1596 runs, and they handle the NDA relationships with Foundries that are almost
1597 impossible to otherwise establish.

1661 # 3.2 Capacity of participants and consortium as a whole
1662
1663
1664 The majority of the consortium have been working together for over
1665 three years on the precursor technical development of the Libre-SOC core
1666 project, the evolution of which is the lynch-pin and "proving-ground"
1667 of this grant application. The public record of their achievements
1668 and team involvement can be found in their public Open Source record
1669 https://libre-soc.org/.
1670
1671 The Libre-SOC team are internationally experienced software professionals
1672 who have strong familiarity with state of the art software to silicon
1673 technologies. They have been supported by two of the co-applicants labs
1674 CNRS and LIP6 (The applicants being Sorbonne Université and Affiliated
1675 Entity, CNRS), and many other European based technology development
1676 groups, which each provide key elements of the project from specialist
1677 programs such as coriolis2, alliance, HITAS, YAGLE and more, and the
1678 manufacturing expertise of Imec. Their versatility and experience with
1679 Libre/Open Source Software also means that they can adapt to unforeseen
1680 circumstances and can navigate the ever-changing and constantly-evolving
1681 FOSS landscape with confidence.
1682
1683 The above is critically important in light of the requirement to
1684 demonstrate access to critical infrastructure, resources and the
1685 ability to fulfil: with the sole exception of NDA'd Foundry PDKs
1686 (Physical Design Kits), the entirety of this project is Libre/Open
1687 Source, both in the tools it utilises, components that it uses, and
1688 the results that are generated. With there being no restriction on
1689 the availability of Libre/Open Source software needed to complete the
1690 project, the Participants correspondingly have no impediment. We also
1691 have a proven strategy to deal with the NDA's: a "parallel track" where
1692 at least one Participant (Sorbonne Université, LIP6 Lab) has signed
1693 TSMC Foundry NDAs, and consequently there is no impediment there, either.
1694
1695 Sorbonne Université (SU) is a multidisciplinary, research-intensive
1696 and world class academic institution. It was created on January 1st
1697 2018 as the merger of two first-class research intensive universities,
1698 UPMC (University Pierre and Marie Curie) and Paris-Sorbonne. Sorbonne
1699 Université is now organized with three faculties: humanities, medicine
1700 and science each with the wide-ranging autonomy necessary to conduct
1701 its ambitious programs in both research and education. SU counts 53,500
1702 students, 3,400 professor-researchers and 3,600 administrative and
1703 technical staff members. SU is intensively engaged in European research
1704 projects (163 FP7 projects and 195 H2020 projects). Its computer
1705 science laboratory, LIP6, is internationally recognized as a leading
1706 research institute.
1707
1708 LIP6 is a Joint Research Unit of both SU (Sorbonne Université)
1709 and CNRS. Both entities invest resources within LIP6 so CNRS is then
1710 an Affiliated Entity linked to SU. According to SU-CNRS agreement
1711 regarding LIP6, SU, as a full partner, manages the grant for its
1712 Affiliated Entity, CNRS.
1713
1714 RED Semiconductor Ltd has been established as a commercialisation vehicle,
1715 sharing the Libre principles of the core Libre-SOC team and bringing
1716 Semiconductor industry commercial management and technology experience.
1717 This includes the founders of two successful semiconductor companies
1718 and a public company chairman. There is also a cross directorship of
1719 Luke Leighton (of Libre-SOC) giving the company an extensive technology
1720 market and leadership experience.
1721
1722 NLnet is a Netherlands based public benefit organisation that brings
1723 to the table over 35 years of European internet history and well over
1724 two decades of unique real-world experience in funding and supporting
1725 bottom up internet infrastructure projects around the world - engaging
1726 some of the best independent researchers and developers. NLnet has
1727 funded essential work on important infrastructure parts of the internet,
1728 from the technologies with which the answers from the DNS root of the
1729 internet can now be trusted, all the way up to key standards for email
1730 security, transport layer security, email authenticity, and a lot more
1731 - on virtually every layer of the internet, from securing core routing
1732 protocols to browser security plugins, from firmware security to open
1733 source LTE networks.
1734
1735 Most recently NLnet is hosting the NGI0 Discovery, NGI0 PET and NGI
1736 Assure open calls as part of the Next Generation Internet research and
1737 development initiative, of which NLnet supports 300+ open source software,
1738 open hardware and open standards projects to build a more resilient,
1739 sustainable and trustworthy internet.
1740
1741 NLnet, a Stichting / Foundation, has been Libre-SOC’s funding source
1742 from the beginning and fundamentally understands our technology and
1743 direction of travel. As well as providing augmentation under existing
1744 EU Grants funding for technology opportunities that we will benefit from
1745 but are yet to be identified, they are a fundamental sounding board that
1746 will be invaluable to the project moving forward.
1747
1748 Helix develops antennas and electronic systems for PNT (Position,
1749 Navigation, Timing) applications. Markets include defence/security,
1750 asset tracking, autonomous systems/vehicles/drones/robotics, critical
1751 infrastructure (network sync – 5G, V2X, etc), fintech (blockchain
1752 timestamping) and many other industrial applications.
1753
1754 Helix solutions defend against the vulnerabilities and threats to
1755 global dependency on GNSS (Global Navigation Satellite Systems), where
1756 disruption to services would cost the world’s major economies £10s
1757 of Billions every single day. Our patented technology enables filtering
1758 antennas to mitigate multi-path, RF and electrical interference and
1759 reduce the impact of jamming and spoofing, meaning that the receiver
1760 electronics becomes a streamlined high performance, low-power/low-cost
1761 correlator/processor to deliver highly accurate and resilience x,y,z
1762 and time data as its output. We are developing sophisticated anti-
1763 jamming/spoofing hardware that uses targeted nulling to ignore jamming,
1764 and enable system-level resilience. This capability can be co-designed
1765 with the receiver chipset for ultimate resilience.
1766
1767 Regarding the extreme high-end computing resources necessary to complete
1768 the exceptionally-demanding task of VLSI development and Layout, we
1769 find that high-end modern laptops and desktop computers (with 64 to
1770 256 GB of RAM) are perfectly adequate. However in the event that our
1771 immediately-accessible computing resources are not adequate, both Sorbonne
1772 Université (LIP6 and CNRS) and Libre-SOC qualify for access to Fed4Fire
1773 (https://www.fed4fire.eu/- grant agreement No 732638) which gives us
1774 direct access to large clusters (100+) high-end servers. Additionally,
1775 we are specifying some of these high-end computers in our budget, and
1776 the software to run on them is entirely Libre-Licensed and within our
1777 combined experience to deploy.
1778
1779 We have established that Embecosm Gmbh and Vrull.eu are some of the
1780 world's leading experts in Compiler Technology. We will put out to
1781 tender a Contract with an initial evaluation phase, followed by a TRL
1782 4/5 Research phase for the prerequisite compilers (gcc, llvm, Kazan,
1783 MESA3D) necessary to support the core design work.
1784
1785 The OpenPOWER Foundation is a part of the Linux Foundation,
1786 and is directly responsible for the long-term protection
1787 and evolution of the Power ISA. Members include IBM, Google,
1788 NVidia, Raptor Engineering, University of Oregon and many more.
1789 https://openpowerfoundation.org/membership/current-members/.
1790
1791 The Chair of the newly-formed ISA Working Group is Paul Mackerras, and
1792 the Technical Chair is Toshaan Bharvani. Both of these people have
1793 been kindly attending bi-weekly meetings with the Libre-SOC Team for
1794 over 18 months, and we have kept them apprised of ongoing developments,
1795 particularly with the Draft SVP64 ISA Extension. They are both going
1796 out of their way to regularly advise us on how to go about a successful
1797 RFC Process for SVP64, and we deeply appreciate their support.
1798
1799 Helix Technology's involvement, as a potential customer and potential
1800 user of the Libre-SOC technology, will give focus to the deliverable of
1801 the project. They have world-leading expertise in Antenna Technology,
1802 and in the mathematics behind the Signal Processing required for
1803 GNSS/GPS. We have deliberately selected them to ensure the ambition of
1804 our overall project.
1805
1806 We therefore have a cohesive cooperative team of experience from concept
1807 to customer product and a supporting cast of specialist technical support
1808 that are an established practiced team.
1809
1810 As a last point: the creation of the teams for this project is critical
1811 for RED Semiconductors Limited and Libre-SOC. We have the benefit of
1812 having the core of an International Technology Headhunter Research
1813 Team amongst the directors of RED Semiconductor Limited, giving us
1814 the capability to ensure the project is fully manned in the required
1815 timescales without the need to externally resource recruitment services,
1816 and this is included in RED’s management manpower.
1817
