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
