Abstract – An embedded system is a system that has embedded software in computer hardware dedicated for an application. Embedded systems are electronic systems that contain microprocessor or microcontroller, but we do not think of them as computers. We all are surrounded by an embedded system from everywhere. Embedded system finds applications in each and every field. An embedded system has three main components. First one is its hardware which include embedded processor, peripheral,input output devices. Embedded hardware is the heart of embedded system.Second part is the software that is ROM,flash memoryor media card. This is the brain of an embedded system. Third part is a Real Time Operating Systems (RTOS).The RTOS supervises the application software and control the access to system resources. This Technology based on the advancement made in development of IC fabrication process. It smartly integrate electronics, electrical & Mechanical components on a single silicon wafer similar to integrated circuit technology Basically Embedded system believes in Good things comes in small packet. To satisfy today’s market demand miniaturization is the only solution. The miniaturized devices are particularly suited for biomedical & aerospace application due to their minute size & weight. Embedded systems are characterized by special feature.Embedded system have to work against some deadlines and are constrained for power.This systems need to be highly reliable.Some embedded system have to operate in extreme environmental conditions such as very high temperatures and humidity.
