WebAug 7, 2016 · The four steps which the CPU carries out for each machine language instruction: fetch, decode, execute, and store. Each of these steps would typically happen in a different cycle. "Execute" is a complicated process involving some sub-steps and plenty of transistors, but for most instructions it can still be done in a single cycle.
