You must be kidding. Normal CPU architectures - the RISC ones - don't have funny things like "microcode" (well, true RISCs don't have it for sure). Majority of CPU architectures nowadays are RISCs. Some legacy ones, like x86, are CISC-translated-to-RISC, as this presentation shows. The native RISC code in them is called "microcode".
