What would be awesome if instead of a Rosetta-like (or qemu-user-like) compatibility layer, the chip supported multiple ISAs natively.
The only company that has the rights to do both ARMv8 and amd64 is.. AMD :)
- Symmetry 7y agoThat would be nice but NVidia got in legal trouble with x86 patents when they tried to do that with their Project Denver. https://en.wikipedia.org/wiki/Project_Denver https://en.wikipedia.org/wiki/Project_Denver
- mappu 7y agoMost of the original x86_32 patents have now expired, that was sufficient to let Microsoft build the emulation layer for WoA. It might be more feasible now, except in the last ~5-10 years there's been a push to make many PC apps x86_64 only (e.g. Ubuntu dropping i386 support), so the benefit isn't quite as wide any more.
- floatboth 7y agoDo software implementations have to care? qemu implements like every ISA out there..
- mappu 7y agoPresumably so, or Microsoft would have extended the WoA compatibility to x86_64 as well.
