x86 vs ARM; Vector and Matrix Extensions; How do they compare?

• ara

  5 304 7.5 C

  The PULP Ara is a 64-bit Vector Unit, compatible with the RISC-V Vector Extension Version 1.0, working as a coprocessor to CORE-V's CVA6 core (by pulp-platform)

  

yeah, ara also currently doesn't work, but that it exist is already really cool, and will likely get fixed and completed in the future

• riscv-v-spec

  43 858 6.0 Assembly

  Discontinued Working draft of the proposed RISC-V V vector extension

  

And this isn't just some theoretical or something unlikely to happen - the official spec already contains such a bug. If the writers of the spec can't get things right, even with the small amount of code in the spec, I don't have high hopes that less informed programmers will. RVV being absurdly complicated (IMO, compared to SVE2 and AVX10) doesn't help its cause here.
