Basics of microprocessor

Basic’s of Microprocessor

Introduction• The ease with which computers can process data, store and retrieve it painlessly have made in office and business environments.• Computers can perform all of this because of its brain- the microprocessor.• It is the microprocessor that carries out the machines-instructions as per the program.

Microprocessor Basic• A microprocessor is also called as a CPU is

a multipurpose, programmable logic device(IC) that reads binary instructions from a storage device called memory, accepts binary data as input and process data according to those instructions and provides result as output.

There are some basic characteristics of microprocessor that define the power and capacity of microprocessor

The basic characteristics are given below:

1. Instruction sets2. Word Size3. Clock Speed

Instruction Set• The possible operations a

microprocessor can execute it is determined through its instruction set.

• Programs are written for a microprocessor based on its instruction set.

Word Size• The number of bits processed in

single instruction depend upon the word size of a microprocessor.

• The word size determines the amount of information that can be processed and the amount of RAM memory that can be accessed.

Clock Speed• It is also called clock rate, the clock speed is the

speed at which a microprocessor executes instructions.

• Every computer contains an internal clocks that regulates the rate at instruction which

• Instructions are executed and synchronizes all the various type of computer.

• SIMP computer understands 10 instructions, and any program are written for its
