[attachment=48306]
Definition for: embedded system
A combination of hardware and software which together form a component of a larger machine.
An example of an embedded system is a microprocessor that controls an automobile engine.
An embedded system is designed to run on its own without human intervention, and may be required to respond to events in real time.
Application Areas
Automobiles
engine management, trip computer, cruise control, immobilizer, car alarm,
airbag, ABS, ESP, …
Building Systems
elevator, heater, air conditioning, lighting, key card entries, locks, alarm systems, …
Agriculture
feeding systems, milking systems, …
Space
satellite systems, …
Input and Output
Required to communicate with outside world
PC System:
Keyboard
Monitor
Parallel port (printer port)
Serial port + USB
Embedded System:
Sensors (e.g. in automobile: acceleration sensor, seat sensor)
Actuators (e.g. in automobile: valves for airbags)
