It's fair to say that x86 or x86-64 instructions are also emulated by some lower-level machine which maps the small number of registers onto a larger register file and translates instructions into something else.
- formerly_proven 2y agoNot in the same sense that the typical minicomputer CPU used microcode, no.
- kragen 2y agoi agree, but i also think it's fair to say that the i386 and amd64 instruction sets are the native machine code they implement. both of these contradictory points of view are useful oversimplifications of reality that are useful for certain purposes
