What is an Embedded System?

An embedded system is some combination of computer hardware &

software, either fixed in capability or programmable, that is specifically

designed for a particular kind of application device

Embedded System Design : H/W +S/W

Application Software

OS (porting or design)

Device Driver

Hardware (target platform)

One of the first recognizably modern embedded systems wasthe Apollo Guidance Computer, developed by Charles StarkDraper at the MIT Instrumentation Laboratory

An early mass-produced embedded system was the AutoneticsD-17 guidance computer for the Minuteman missile, releasedin 1961

Since these early applications in the 1960s, embedded systemshave come down in price and there has been a dramatic rise in

processing power and functionality.

The first microprocessor for example, the Intel 4004, wasdesigned for calculators and other small systems but still

required many external memory and support chips. In 1978National Engineering Manufacturers Association released a"standard" for programmable microcontrollers, includingalmost any computer-based controllers, such as single boardcomputers, numerical, and event-based controllers.

Embedded systems are designed to do somespecific task, rather than be a general-purposecomputer for multiple tasks. Some also havereal-time performance constraints that must bemet, for reasons such as safety and usability;

others may have low or no performancerequirements, allowing the system hardware tobe simplified to reduce costs.

Thus embedded systems contain programmedinstruction running via processor chips. Theyperform control, protection & monitoring tasks.

In broad terms embedded systems areprogrammable devices or systems which aregenerally used to control or monitor things likeprocesses machinery, environmental

equipment & communications.
