The original ARM 32 stuff is clearly out of patents and is not being copied. And it doesn't require new extensions to be commercially viable.

- userbinator 8mo agoand is not being copied Are you sure, especially considering China? I doubt there is any legal barrier, because there are a few existing projects with x86 cores on an FPGA, as well as some SoCs. Here's a 486: https://opencores.org/projects/ao486 https://opencores.org/projects/ao486
- panick21_ 8mo agoOk if China is doing something only for China market that tells you something. As for opencores, yes you can design them, but do any companies making commercial products sell them?
