What is an embedded system?An embedded system is a microprocessor usedas a component in another piece of technologyIt is used in things like:• cell phone• digital camera• appliances• car antilock brake system
What an embedded system is not• An embedded system is not a microprocessorused in a “traditional” computing application– desktop– laptop– workstation
4 Major types of embedded systems1. General– similar to traditional computer systems, in a smaller package– PDA’s– portable games2. Communications– cell phones3. Signal Processing– video and audio4. Control– real time feedback control– automotive– aerospace– appliances
Benefits of embedded systemsEmbedded system applications have benefits overtraditional applications. These include:• cost• reliability• safety• real time critical• interface to environment through sensors andactuators• “hybrid” behavior – interaction of continuousdynamics with logic and ﬁnite state machines
