RV64X: a free, open source GPU for RISC-V

A group of enthusiasts are proposing a new set of graphics instructions designed for 3D graphics and media processing. These new instructions are built on the RISC-V base vector instruction set. They will add support for new data types that are graphics specific as layered extensions in the spirit of the core RISC-V instruction set architecture (ISA). Vectors, transcendental math, pixel, and textures and Z/Frame buffer operations are supported. It can be a fused CPU-GPU ISA. The group is calling it the RV64X as instructions will be 64-bit long (32 bits will not be enough to support a robust ISA).

There's a lot of activity around RISC-V, and with it being open and freely usable, a lot of - at first - cheaper, embedded uses will be taken over by RISC-V, hopefully followed by more performant use cases in the near future.
