How does the fetch execute cycle work
WebThis video shows the operation of a simple computer, breaking down the fetch/decode/execute cycle into the actions on an individual bus.The program in memory... 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.

WebJun 14, 2024 · The Fetch-Decode-Execute cycle of a computer is the process by which a computer: fetches a program instruction from its memory, determines what the instruction wants to do, and carries out those actions. This cycle is repeated continuously by the central processing unit (CPU), from bootup to when the computer is shut down. WebThis is a multi-step process in which instructions are fetched, decoded, executed, and then stored. The result of this cycle allows an instruction to be executed by the CPU allowing …
