    that does almost seem to be a something you would expect with pipelining or else you would have some gap of clock cycles between the stages each time the cpu fetches a new instruction.

    how common is the fetch-execute overlapping in modern cpus? it seems common sense to have the next instruction fetched by the time the preceding one is executed unless the code jumps memory locations . .
