Updated: 02/07/2022 by Computer Hope The steps performed by the computer processor for each machine language instruction received. The machine cycle is a four-process cycle that includes reading and interpreting the machine language, executing the code, and then storing that code. Tip The process of cycling instructions may also be known as the E-cycle (execution cycle), I-cycle (instruction cycle), fetch-decode-execute cycle, or fetch-execute cycle.
Below is an example of a machine cycle performing the steps mentioned above for a math problem.
Improvements with pipeliningEarly computer processors needed to wait until an instruction completed all four stages before beginning work on the next instruction. However, today's computers use pipelining, which allows the processor to begin fetching a second instruction before it has completed the machine cycle for another instruction.
