[B]ABSTRACT:[/B]

An embedded system can be defined as the computing device that has computer hardware with software embedded in it as one of its most important component. It may be either an independent system or a part of a larger system. The emergence of embedded systems is a recent development. As a scientific discipline it resembles the state of microelectronics (and VLSI design, in particular) around 1980. Today's challenge is similar to back then, except that the stakes are probably higher. Embedded systems will appear in virtually all devices, and intelligent devices have the tendency to oust their "stupid" counterparts from the market place, just like CD players have ousted gramophone players. Thanks to developments in microelectronics, the computing power of the desktop computers is now becoming available on the palmtops. Embedded systems are heterogeneous. Since they are mixtures of hardware and software, trade-off are important design decisions: do we realize a function in hardware or in software? But embedded systems are more heterogeneous than just combining computer science and digital electronics.
This paper presents an overview of existing modes of Embedded Systems, architecture and their application. A look has also been given to future deployment of Embedded Systems.
