Outlines Steps in ‘Data-Fetch-Execute’ Cycle in a Simple Form

Micro-computer can perform the data read and write operations with the memory. When the memory is receiving data from microcomputer, it is called a WRITE operation, and data is stored into a selected memory location. When the memory is sending data to microcomputer element it is called a READ operation.

As soon as a computer is powered on, it begins the process of the fetch-execute cycle. This cycle is however, from the beginning of the PC startup, the computer is run. The cycle contains 3 main parts.

(i) Fetch next instruction

(ii) Decode instruction

(iii) Run instruction

 

The Fetch Cycle

Fetch execute cycle is the very basic way a computer works. It collects data from the memory and stores it in the MBR as well as setting the program to load the next step.
