WebAug 7, 2016 · The purpose of the CPU is to process data. The CPU works by following a process known as ‘fetch, decode and execute’. The CPU fetches an instruction from memory, decodes this instruction and then executes it. The CPU carries out this cycle continuously, millions of times per second. WebThe CPU system first fetches the data and instruction from the main memory and store in the temporary memory, which is known as registers. This phase is known as the fetch …

WebFetch, decode and execute cycle are the three steps that the CPU repetitively performs to complete one program instruction. The instruction cycle comprises three main stages and is also addressed as the fetch-decode-execute cycle or fetch-execute cycle because of the steps involved. They are as follows: 1. Fetch stage. 2. 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 … See more The program counter (PC) is a special register that holds the memory address of the next instruction to be executed. During the fetch stage, the address stored in the PC is copied into the memory address register (MAR) and … See more Each computer's CPU can have different cycles based on different instruction sets, but will be similar to the following cycle: 1.
