A pipelined computer usually has "pipeline registers" after each stage. These store information from the instruction and calculations so that the logic gates of the next stage can do the next step. This arrangement lets the CPU complete an instruction on each clock cycle. See more In computer engineering, instruction pipelining is a technique for implementing instruction-level parallelism within a single processor.

Also note that you always need to save all signals (control and data) between one stage and another.

WebThe CPU multiplier (sometimes called the “CPU ratio”) expresses the CPU’s performance as a multiplier of the CPU Base Clock (or BCLK) speed. A CPU multiplier of 46 and a base clock of 100 MHz, for example, results in a clock speed of 4.6GHz.
