Microprocessor,Microcomputer,Microprocessor Characteristics and Features of Microprocessor

Introduction To Microprocessor

Microprocessor:-

• A microprocessor is a central processing unit build on a single IC.

• It consists of very small transistors fabricated on a single semiconductor IC.

• One or more microprocessors typically serve as a CPU in a computer system.

Microcomputer:-

•Microcomputer is a digital computer in which there is one microprocessor which acts as a  CPU.
•Examples: A desktop computer, palmtop, notebook, laptop, etc.

Characteristics of Microprocessor:-

•INSTRUCTION SET:

•The set of instructions that a microprocessor can understand.

•BANDWIDTH:

•The number of bits processed in a single instruction.

•CLOCK SPEED:

The number of operations performed by the processor per second.

•Width of data bus:

•It defines the number of bits that can be transferred through data bus.

•Width of Address Bus:

•This parameter decides the memory addressing capability of the microprocessor.

•Interrupt Capability:

•This feature interrupts the microprocessor whenever a task which is more prior than the one being done by microprocessor arrives.

•Microprocessor is interrupted and the contents are saved in the stack register and the current address is saved on the program counter.

Features of Microprocessor

•Low Cost

•Small Size

•Low Power Consumption
