Risc-v gpu

Is there anyone out there working on V extension GPU ?

The V extension is still in draft. It is a CPU instruction set extension, not a GPU, but you could do some software accelerated graphics using it. There are a number of companies involved with the V extension committee, and it is a fair assumption that most of them are looking at V extension implementations. A few of these were announced at the recent RISC-V Summit.

I haven’t looked at them all, but there are at least four that talk about vector support, UC Berkeley, Esperanto, VectorBlox, and ETH Zurich. Not all of those are straight V extension implementations, some are experimental, and some are proprietary.

It will likely be awhile before anything is commercially available, and even longer before anything is available to consumers.

Thank you Jim.
