Introduction To Micro controller System

Embedded systems are controllers with on chip control. They consist of micro controllers, input and output devices, memories etc., on chip and they can be used for a specific application.

A small computer designed in a single chip is called a single chip microcomputer. A single chip microcomputer typically includes a microprocessor RAM, ROM, timer, interrupt and peripheral controller in a single chip. This single chip microcomputer is also called as micro controller; These Micro controllers are used for variety of applications where it replaces the computer. The usage of this microcomputer for a specific application, in which the micro controllers a part of application, is called embedded systems.

Embedded systems are used for real time applications with high reliability, accuracy and precision, Embedded systems are operated with Real Time Operating systems like Wince, RT Linux, VxWorks, PSOS, etc..,

Embedded systems are very popular these days Most of the Electrical, Electronics, Mechanical, Chemical, Industrial, Medical, Space and many more areas have the embedded systems in their applications
