Introduction of Microprocessor

A Microprocessor is an important part of a computer architecture without which you will not be able to perform anything on your computer. It is a programmable device that takes in input, performs some arithmetic and logical operations over it, and produces the desired output. In simple words, a Microprocessor is a digital device on a chip that can fetch instructions from memory, decode and execute them and give results.

Basics of Microprocessor:

  • A Microprocessor takes a bunch of instructions in a machine language and executes them, telling the processor what it has to do. Microprocessor performs three basic things while executing the instruction :
  1. It performs some basic operations like addition, subtraction, multiplication, division, and some logical operations using its Arithmetic and Logical Unit (ALU). New Microprocessors also perform operations on floating-point numbers also.

  2. Data in microprocessors can move from one location to another.

  3. It has a Program Counter (PC) register that stores the address of the next instruction based on the value of the PC. The Microprocessor jumps from one location to the other and makes decisions.

What is a Microprocessor ?

  • A microprocessor is a computer processor where the data processing logic and control are included in a single integrated circuit or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer’s central processing unit.
