I'm hoping for an eventual RISC-VI where all lessons learned in RISC-V are used and the instruction encoding is completely redone from scratch. I doubt it will happen, but it's what I hope for some day.
- ncmncm 4y agoI call this Risc-6: The RISC-V "Good Parts" edition, leaving behind the academic complications and unfortunate premature pessimizations, crystallizing out a single compilation target that is simplest to implement for maximum performance for mainstream implementations. The expensive formal verification work could be inherited by fixed mapping.
- panick21_ 4y ago> instruction encoding is completely redone from scratch Why? That makes no sense. Its like, lets do 100 of man years of work so maybe we can do a few % better on encoding if you will do better at all.
- sylware 4y agoyep, I was more talking about instruction semantics, not really the encoding itself. And even with fixes since software should come as assembly source files ultimately with risc-v, we should be sort of very fine, even if the encoding does change. We are not talking about absurdely and grotesquely complex c++ compiler backends!
