Re: Zvediv extension discussions

I hope that these discussions will begin with algorithms and applications that need the additional performance, and proceed to analyze how proposed instructions address the greater need.

In the Graphics/ML SIG, we also discussed matrix operations as well.  We talked about a single matrix opcode with various functions like vector-matrix, matrix-matrix, and dot product functions, among others.  Just some initial ideas... 

The Zvediv extension would be a great start to get dimensionality to vectors, and we would want to keep matrices in mind when reviving the effort.

I am hearing renewed interest in adding a dot-product extension to the RISC-V Vectors. This includes everything from adding a handful of FP and Int dot-product instructions all the way to completing the Zvediv extension.

What is the most efficient way to revive the efforts in these areas? Can we reconvene the Vector TG meetings?

Thanks,
Ken
