[1] Not exactly microcode as that term is classically understood, but there isn't really a better term for it that's widely used. What are technically correct but less widely used terms? And how does the current Intel approach differ from classical microcode? Most of my knowledge is from the Intel manuals, so I don't have a context for how it is different than other approaches.
