Rivos was formed from a bunch of ex-Apple CPU engineers. I'm sure they would feel more comfortable with a closer to AArch64 derived design as well.

- gchadwick 3y agoThey might also know a bunch of techniques to give high performance that only work if you've got nice 32-bit only aligned instructions!
- kajiryoji 3y agoHaha that'd be a little counterintuitive given all 32-bit aligned is the trivial case for decoding variable length instructions, unless you're thinking about prefetching/branch prediction etc
- lmm 3y ago> all 32-bit aligned is the trivial case for decoding variable length instructions That's the point? You can go faster if everything is 32-bit aligned, i.e. you don't have variable length instructions.
