- yjftsjthsd-h 4y agoSomehow I doubt that they're much more friendly about it. At a technical level, though it's an interesting question; I'm actually pretty curious to know whether you could make a processor that's pure amd64 without the legacy 32-bit mode... I suspect it would be a fair bit of work from the software side to support that, but it's probably possible. But I'm no ISA designer:) Edit: Or is 32-bit x86 so old that you could "just" clone it because all the patents have expired?
- ZiiS 4y agoamd64 uses Intel IP; even if you removed all legacy modes.
- Steltek 4y agoHistorically, Intel and AMD had an exclusive IP sharing agreement with each other. That would not extend to other parties.
- wolpoli 4y agoSo it means the entity wanting to develop an amd64 processor will need licenses from both Intel and AMD. I don't see how this could practically happen through.
- Pet_Ant 4y agoI don't know how far you'd get with an amd64 core that didn't support x86. I mean you couldn't run Windows on it. You probably could run Surface as it's almost certainly legacy-free as it can run on ARM.
