embedded system Last modified: Thursday, December 05, 2002
A specialized computer system that is part of a larger system or machine. Typically, an embedded system is housed on a single microprocessor board with the programs stored in ROM. Virtually all appliances that have a digital interface -- watches, microwaves, VCRs, cars -- utilize embedded systems. Some embedded systems include an operating system, but many are so specialized that the entire logic can be implemented as a single program.

embedded system
An embedded system is some combination of computer hardware and software, either fixed in capability or programmable, that is specifically designed for a particular kind of application device. Industrial machines, automobiles, medical equipment, cameras, household appliances, airplanes, vending machines, and toys (as well as the more obvious cellular phone and PDA) are among the myriad possible hosts of an embedded system. Embedded systems that are programmable are provided with a programming interface, and embedded systems programming is a specialized occupation.
Certain operating systems or language platforms are tailored for the embedded market, such as EmbeddedJava and Windows XP Embedded. However, some low-end consumer products use very inexpensive microprocessors and limited storage, with the application and operating system both part of a single program. The program is written permanently into the system's memory in this case, rather than being loaded into RAM (random access memory), as programs on a personal computer are.

QUESTION: What is an embedded system?
ANSWER: An embedded system is a single-purpose computer built into a larger system for the purposes of controlling and monitoring the system [1]. A general purpose computer (e.g. a personal computer) is defined not to be an embedded system.
Examples: cell phones, DSTV decoders, MP3 players, ABS breaking systems, and satellite guidance avionics.

embedded system Definition
Hardware and software which forms a component of some larger system and which is expected to function without human intervention. A typical embedded system consists of a single-board {microcomputer} with software in {ROM}, which starts running some special purpose {application program} as soon as it is turned on and will not stop until it is turned off (if ever). An embedded system may include some kind of {operating system} but often it will be simple enough to be written as a single program. It will not usually have any of the normal {peripheral}s such as a keyboard, monitor, serial connections, mass storage, etc. or any kind of user interface software unless these are required by the overall system of which it is a part. Often it must provide {real-time} response. {Usenet} newsgroup: {news:comp.arch.embedded}. (1995-04-12)

A combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a dedicated function. In some cases, embedded systems are part of a larger system or product, as in the case of an antilock braking system in a car. Contrast with general-purpose computer.
