It is usually embedded as part of a complete device including hardware and mechanical parts. Embedded systems have become very important today as they control many of the common devices we use.

Some of the applications of embedded systems are:
* Consumer Electronics: Microwave ovens, digital cameras, CD players, DVD players, washing machines, set top box etc.
* Telecommunications: Telephone switches, cellular phones, web-enabled navigation systems, radios, personal communication devices, PDAs etc.
* Medical: Biologically interfaced systems, Medical control systems, Pacemakers etc.
* Automotive: Engine controllers, anti-lock brake controllers etc.
* Plant control: Robots, plant monitors, industrial process systems, airplane control systems, missile guidance systems etc.
* Home automation: Uses wired- and wireless-networking that can be used to control lights, climate, security, audio/visual, etc.,

However, they also exhibit many non-functional requirements that make the task especially challenging:

• Real-time deadlines that will cause system failure if not met;
• Multi-rate operation
• In many cases, low power consumption
• Low manufacturing cost, which often means limited code size.
• Must be efficient
• Energy efficient
• Code-size efficient (especially for systems on a chip)
• Run-time efficient
• Weight efficient
• Cost efficient
• Dedicated towards a certain application
Knowledge about behavior at design time can be used to minimize resources and to maximize robustness
• Dedicated user interface (no mouse, keyboard and screen)
• Hybrid systems (analog + digital parts).
