I'm also a fan of Itanium. Instruction encoding is a bit weird (41 bits, really?), but many cool ideas to give the compiler more control. My point was that if microcode were the same as simply expanding CISC…
Microcode isn't the same a RISC. With an actual instruction set you are bound to an architecture, microcode changes with the microarchitecture so it can contain optimizations that would break compatibility if used in a…
