Introduction An embedded system is a computer system designed

to do one or a few dedicated and/or specific functions

“Embedded System", it constantly evolves with

advances in technology and dramatic decreases in the

cost of implementing various hardware and software

components.

In recent years, the field has outgrown many of its

traditional descriptions.

Basic Principles Almost all the Embedded System applications share a common Embedded System model which includes:

Hardware Layer

System Software Layer

Application Software Layer

Embedded System Designing and Architecture

In order to design an Embedded System certain processes are as followed:

CreationImplementationTestingMaintenance

General Characteristics of Embedded Systems

Perform a single task Usually not general purpose

Increasingly high performance and real time constrainedPower, cost and reliability are important considerationsHW-SW systems

Software is used for more features and flexibility(R.T.O.S)Hardware (processors, ASICs, memory etc. are used for performance and security

Types of Embedded System

General ComputingVideo games, set-top boxes, wearable computers, Automatic tellers

Control SystemsVehicle engines, chemical processes, nuclear power, flight control

Signal Processing Radar, Sonar, video compression

Communication & NetworkingTelephone system, Internet

Economical AspectEconomical metrics are mostly used to determine which COTS should be use or if the systems will be brought into the market.

Importance of Embedded Software

and Embedded Processors

“... the New York Times has estimated that the

average American comes into contact with about 60

micro-processors every day....” [Camposano, 1996]

Latest top-level BMWs contain over 100

microprocessors [Personal communication]

16

It is estimated that each year embedded software is written five times as much as 'regular' software

The vast majority of CPU-chips produced world-wide today are used in the embedded market ... ; only a small portion of CPU's is applied in PC's

... the number of software-constructors of Embedded Systems will rise from 2 million in 1994 to 10 million in 2012;... the number of constructors employed by software-producers 'merely' rises from 0.6 million to 1.1 million.
