INTRODUCTION:Embedded systems are computer systems that form part of a larger system. These systems are ubiquitous and diverse, and include mobile phones, entertainment devices, automobiles, toys, smart cards, medical devices, network switching equipment, sensors, and industrial robots. Many embedded systems are real-time systems and have to react to external events within a defined period of time. Other constraints such as size, energy supply and unit price often severely limit the design space, affecting costs and reliability. This has resulted in an emerging trend to integrate previously isolated systems. As embedded systems are increasingly networked and expected to execute downloaded code, they have become subject to attacks by hackers or viruses. This means that they now face many of the resource management and security issues associated with traditional computing systems, and makes operating systems, and compilers and language techniques increasingly relevant in the embedded domain.
