Been studying RISC-V for... I think a year now. Bought the booklet outlining the ISA's modules, and have been working down from there.

I have seen various startups and actual products, as well as a bunch of simulators, but I haven't really seen any projects trying to design a RISC-V CPU from the ground up.

Are there any groups doing this? I don't think I'm at a point where I could meaningfully contribute, I'm mostly interested for educating myself.

I guess just making sure my understanding aligns - RISC V being the instruction set, and you are wondering if anyone is building a CPU to implement it?

Came across a couple examples, if that’s what you mean

That's correct. I'm interested in seeing hardware implementations of it.

I know LTT has a bit of a bad wrap these days. But he had a video on RISC V a while ago, in a desktop computer https://youtu.be/vaMxTSm53UU?feature=shared

I'd recommend the Explaining Computers videos on RV over LTT, especially since the guy at EC does a lot more research into RISC-V, and does yearly "state of RISC-V" videos.

Thanks for the recommendation!
