WebApr 7, 2024 · In practice, every pipeline stage takes one clock cycle. "Latency" is the time from the start of the instruction to the point where the result can be used. For example, it takes some time from starting execution of an instruction x = y * z until an instruction a = b + x can start, because the result of the first instruction must first be available.

"WebPipelining. How Pipelining Works. PIpelining, a standard feature in RISC processors, is much like an assembly line. Because the processor works on different steps of the instruction at the same time, more instructions can be executed in a shorter period of time. A useful method of demonstrating this is the laundry analogy. " - Shuffling instructions cpu pipeline
