What is an Embedded SystemAuthor

An embedded system is a very small computer that gets buried in a larger system.

  • One example would be the small computers that control the engine in an automobile.
  • Another would be the tags that manufacturers attach to shipping containers

The term embedded systems is not in many job descriptions today, but embedded systems will strongly influence the architecture of most of tomorrow's software development.

Embedded systems have a few common traits

  • Small memory footprint or at least limited memory
  • Real time requirements. They respond to events in the real world. They have to respond within some small time limit or their response is useless. This is also called event driven programming

Analysts who write specifications for embedded systems very often use state machines to specify system behaviour
