cpu architecture – How many clock cycles do the stages of a simple 5 stage processor take?

Classic 5-stage RISC pipelines are designed around single-cycle latency L1d / L1i, allowing 1 IPC (instruction per clock) in code without cache misses or other stalls. ie the hopefully common / good case. Every stage must have a worst-case critical path latency of 1 cycle, or trigger a stall. Clock speeds were lower back then … Read more
