Embedded systems are devices used to control, monitor or assist the operation of equipment, machinery or larger systems. In electronics industry, numerous devices have been designed having a some sort of microprocessor or a corresponding processor as the basic functional component. This processor can be positioned in connection with a microcontroller, wherein it has some peripherals positioned in the same microchip. These devices are also called an embedded system. The term "embedded" reflects the fact that these components are an integral part of the overall system. Embedded systems generally are developed around custom hardware, require high quality and reliability, and frequently deal with real-time or multi-tasking environments for specific applications. Embedded computer systems typically include a processor to run the code, a non-volatile memory to store the code, and a volatile memory to store data and temporary information the code uses. In most systems the volatile memory is random access memory (RAM) and the non-volatile memory is programmable read only memory (PROM). An embedded computer system is a computer which is physically embedded within a larger system and whose primary purpose is to maintain some property or relationship between the other components of the system in order to achieve the overall system objective. Embedded systems are now used in a wide variety of systems, such as aircraft, automobiles, appliances, weapons, medical devices, and computer peripheral devices. Actually, embedded systems include almost any device, which employs a microprocessor and/or a microcontroller and is not directed only to general-purpose computation. Examples of embedded systems may include cellular phones, set-top boxes, and PDA (personal digital assistant) etc.
