"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
