Intelligent Systems

• What is Embedded System in General?

It is a combination of Computer Hardware, Software and perhaps additional Mechanical Parts, designed to perform a Specific Function.

• Gadgets are increasingly becoming Intelligent and Autonomous.

• The Intelligence of these Smart Devices resides in Embedded Systems.


Desktop Vs Embedded System

• In contrast to Desktops that performs a Variety of Tasks, an Embedded System performs a Single, Well-Defined Task.

• The System has a Processor, Associated Peripherals, and Software for a Specific Purpose.

• For example, in a Mobile Phone the Embedded Processor needs to Process Voice (to Send and Receive Speech Signals) as well as implement Communication Protocols.

• The Hardware is Custom Built for the Specific Purpose.
