An instruction cycle is the basic operational process of a computer. It is the process by which a computer retrieves a program instruction from its memory, determines what actions the instruction dictates, and carries out those actions. This cycle is repeated continuously by a computer's central processing unit (CPU), from
In this tutorial we will learn about different Addressing Modes and Instruction Cycle in Computer Architecture.
Microprocessing unit is synonymous to central processing unit, CPU used in traditional computer. Microprocessor (MPU) acts as a device or a group of devices which do the following tasks. communicate with peripherals devices; provide timing signal; direct data flow; perform computer tasks as specified by the instructions in

This document is to be read in conjunction with the tutorial presented on the. Instruction Fetch Execute Cycle of the Intel processor. The principles are fairly simple and can be easily generalized to any processor or Operating System. It further proceeds to explain what happens when a computer is first switched on till the time
So, the CPU must copy the instruction from memory to the CPU, and once it's in the CPU, it can execute it. The PC is used to determine which instruction is executed, and based on this execution, the PC is updated accordingly to the next instruction to be run. Essentially, a CPU repeatedly fetches instructions and executes
28 Dec 2011 Instruction cycle
- The time period during which one instruction is fetched from memory and execute when a computer given an instruction in machine language.
- Each instruction is further divided into sequence of phases.
- After the execution the program counter is
