EMBEDDED SYSTEM

INTRODUCTION Over the past decade, there has been a steady increase in

the number of applications that demand customized computer systems that offer high performance at low cost.

These applications are, more often than not, characterized by the need to process large amounts of data in real time.

Examples include consumer electronics, scientific computing, and signal processing systems. Constraints on performance, cost and power make software implementations of data processing algorithms for such systems infeasible.

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.

EMBEDDED SYSTEMS : THE DESIGN

A system can be defined as a group of devices or artificial objects or an organization forming a network especially for distributing something or serving a common purpose .

To embed a system into some object means to make that system an integral part of the object.

Examples include DSP processors in hand-held communication devices, programmable controllers installed in robots or cars, and video signal processors in television sets.

EMBEDDED SYSTEM LIFE CYCLE

Component acquisition

Because an embedded system may be more application-driven than a typical technology-driven desktop computer design, there may be more leeway in component selection.

System certification Embedded computers can affect the safety as

well as the performance the system.

Therefore, rigorous qualification procedures are necessary in some systems after any design change in order to assess and reduce the risk of malfunction or unanticipated sys system failure.

Logistics and repair Whenever an embedded computer design is

created or changed,

it affects the downstream maintenance of the product.

A failure of the computer can cause the entire system to be unusable until the computer is repaired.

Upgrades

Because of the long life of many embedded systems, upgrades to electronic components and software may be used to update functionality and extend the life of the embedded system with respect to competing with replacement equipment.

EMBEDDED INTERNET: Used in everything from consumer electronics to industrial

equipment, embedded systems —small, specialized computer systems stored on a single microprocessor — are playing a major role in the growth of the Internet and the boom of wireless communication channels.

Due in part to embedded systems, more and more consumer products and industrial equipment are becoming Internet-friendly.
