Isn't this the Cathedral vs Bazaar debate all over again? All designs have flaws, but at-least with something like the C910 you can open a PR to fix it going forwards.
Sure the first revisions of a new design will be buggy, but over time with iteration and continuous improvement they'll only get better.
I don't think too many folks will be designing new RISC-V cores from scratch, in the same way that very few people build their own OS's. It'll be contributing features and bugfixes to existing designs (and designing custom extensions).
- camel-cdr 2y agoMost RISC-V processors are proprietory, the C910 is partially open source, excluding the draft vector extension implementation where the bug was located.
- dpeckett 2y agoYeh it's a shame T-HEAD didn't release the source for the draft vector extension. Admittedly they had their reasons. While it might be true, and remain true for high-end designs, we're really seeing a proliferation of mid-to-low end RISC-V SoCs out of china based on open source IP.
