(I'm not sure if your "but" is a retort, or an addendum. Assuming retort...) We can consider one more level of implementation machinery, but I fail to understand how uops aren't another form of instruction, and CPU internal gobbledygook like register files, caches, etc. aren't another form of state. It doesn't seem so fuzzy.
- rzzzt 5y agoThe difference is that you don't get to access the uops machine, subsets/sequences of that instruction set are offered as (macro-)instructions instead. Programming happens on the idea of a CPU.
