Introduction of embedded system• An embedded system is a microprocessor-

based system that is incorporated into a device to monitor and control the functions of the components of the device.

• An embedded system is a special-purpose system in which the computer is completely encapsulated by the device it controls.

• an embedded system performs pre-defined tasks, usually with very specific requirements.

Deepak chouhan 4

History• One of the first recognizably modern

embedded systems was the Apollo Guidance Computer, developed by Charles Stark Draper at the MIT Instrumentation Laboratory.

• An early mass-produced embedded system was the Autonetics D-17 guidance computer for the Minuteman missile, released in 1961.

Microcontroller• A microcontroller is a small computer on

a single integrated circuit containing a processor core,memory,and programmable input /output peripherals.

• Microcontroller are designed for embedded applications in contrast to the microprocessor used in personal computer or other general purpose applications.
