-# RISC-V 3D GPU / CPU / VPU
+# Hybrid 3D GPU / CPU / VPU
Creating a trustworthy processor for the world.
See [[3d_gpu/business_objectives]]
-* the project shall be a hybrid CPU-GPU-VPU
-* the project shall be commercial and mass-volume (100 million units
- and above)
-* the project shall be entirely transparent so that end-users will be
- able to trust it
-* the source code shall be available at all times for all components
- for BUSINESS reasons, making development and use of SDKs dead simple
- and aiding and assisting developers AND BUSINESSES in debugging and thus
- hugely saving them money.
-
-Reasoning:
-
-* If the processor is not a hybrid CPU-GPU-VPU, the
- complexity involved in developing a split shared-memory CPU-GPU both
- at a hardware and a software level will be so costly it will jeapordise
- the project.
-* The project is commercial and mass-volume because there are plenty
- of academic designs (none of them reaching production where people
- may benefit), and "Open" designs, created by the Open Hardware
- Community, sadly due to the high cost of producing ASICs, tend to be
- focussed on markets that would have been great about twenty to thirty
- years ago.
-* Transparency is a key business objective. It is a Unique Selling Point
- that the processor is developed in a fashion that, should it be
- independently audited, no opportunity for spying back-door co-processors
- will be found to have "made their way surreptitiously - or overtly -
- into the design". Yes, GCHQ: I know about the conversation you had
- with nCipher (and, to their everlasting credit, that they told you
- to take a hike)
