An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints.It is embedded as part of a complete device often including hardware and mechanical parts. Embedded systems control many devices in common use today.mbedded systems range from no user interface at all, in systems dedicated only to one task, to complex graphical user interfaces that resemble modern computer desktop operating systems. Simple embedded devices use buttons, LEDs, graphic or character LCDs (HD44780 LCD for example) with a simple menu system.
This chapter deals with embedded and real-time space. An embedded system is a device that has a computer inside it, but the user of the device does not necessarily know, or care, that the computer is there. It is hidden. There are a lot more embedded computers out in the world than there are PCs.
