WebEdit. The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetch-execute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions. It is composed of three main stages: the fetch stage, the decode stage, and the execute stage. Web—The clock cycle time or clock period is just the length of a cycle. —The clock rate, or frequency, is the reciprocal of the cycle time. Generally, a higher frequency is better. Some examples illustrate some typical frequencies. —A 500MHz processor has a cycle time of 2ns. —A 2GHz (2000MHz) CPU has a cycle time of just 0.5ns (500ps).

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.
