ESII: Intro and Overview 10 What is an Embedded System? What is an Embedded System? � There is no concise definition of an embedded system There is no concise definition of an embedded system � But here are some common characteristics … But here are some common characteristics … � specialized specialized to an application domain, single application or specific task (=> to an application domain, single application or specific task (=> less flexible but probably more efficiently to design) less flexible but probably more efficiently to design) � Underlies many and Underlies many and tight constraints tight constraints (later) (later) � Designing Designing an embedded system is typically more an embedded system is typically more challenging challenging than than designing a general- designing a general -purpose computer purpose computer � Interacts with the real world � Interacts with the real world Interacts with the real world => designing embedded software requires the Interacts with the real world => designing embedded software requires the => designing embedded software requires the => designing embedded software requires the consideration of more constraints than designing software for general consideration of more constraints than designing software for general- - purpose computers purpose computers � By far By far higher volume higher volume than general than general- -purpose computers. Example: a single purpose computers. Example: a single luxury car has already >100 embedded systems luxury car has already >100 embedded systems l l h h l l d d 100 100 b dd d b dd d t t � Market revenue Market revenue for ES is by far higher than it is for general for ES is by far higher than it is for general- -purpose purpose computers (billions instead of millions) computers (billions instead of millions) � New application areas evolve each day � New application areas evolve each day … New application areas evolve each day New application areas evolve each day … � By exploiting the specific characteristics and by limitation to the known By exploiting the specific characteristics and by limitation to the known requirements an ES can be designed more efficiently => no requirements an ES can be designed more efficiently => no unnecessary overhead unnecessary overhead unnecessary overhead unnecessary overhead http://ces.itec.kit.edu J.
