Definition Edit

Embedded systems are specialized computer systems that are part of a larger system or machine.[1]

An embedded system is

[a] system that performs or controls a function, either in whole or in part, as an integral element of a larger system or subsystem.[2]

Overview Edit

An embedded system may be thought of as a special-purpose computer system, which is completely encapsulated by the device it controls. It is often designed to perform dedicated functions and subject to resource-limitation constraints as part of a mechanical device.

Often embedded system programs are implemented in read-only memory and are not intended to be generally reprogrammable. (In contrast, general-purpose computing systems, such as PCs, execute a wide variety of functions and are easily reprogrammed.) Most embedded systems use a mix of various firmware items that supplement the software running on the volatile memory portion of the system.

Virtually all appliances that have a digital interface — for example, watches, microwaves, video cassette recorders (VCR), digital video disc (DVD) players, and 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.
