Open Source RVV (Vector Unit) implementations

[Sean Halle]

Have any groups released an open source implementation of RVV?

[Tommy Murphy]

Some of the XuanTie open-source RISC-V implementations (or maybe just the C906?) implement RVV but only the pre-ratification v0.7.1 version. But maybe it could be a starting point for somebody who wants to implement the ratified RVV standards?

I compiled a (non-exhaustive) list of RVV cores (both from academia and industry) in a GitHub issue here: https://github.com/tum-ei-eda/muriscv-nn/issues/10.

Great resource, Fabian.  Thank you :-)
