2. Embedded System A microprocessor or microcontroller based system designed to perform one or more dedicated functions with real time computing constraints   Emb edded systems is combination of hardware and software  i.e. an electronic system that has a computer software that is embedded in a computer hardware. A hardware platform is generally a micro controller or processor in which the program is dumped. The hardware has its own software. They are either Machine code (hex code) or Programming code ( C, C++ code). For example, take 8051 controller. Here we embed program into it and it performs the task as per the program instructions . Design of an embedded product has to be optimized to reduce size, cost, weight and improve reliability and performance

3. Due to their compact size, low cost and simple design aspects made embedded systems are very popular and encroached into human lives and have become indispensable. They are found everywhere from kitchen ware to space craft . Application area Biomedical Instrumentation – ECG Recorder, Blood cell recorder, patient monitor system Communication systems – pagers, cellular phones, cable TV terminals, fax and trans receivers, video games and so on. Peripheral controllers of a computer – Keyboard controller, DRAM controller, DMA controller, Printer controller, LAN controller, disk drive controller . Industrial Instrumentation – Process controller, DC motor controller, robotic systems, CNC machine controller, close loop engine controller, industrial moisture recorder cum controller . Scientific – digital storage system, CRT display controller, spectrum analyser .

4. Consumer Electronics Household applications Biomedical systems Home automation Microwave ovens, Television, DVD Players & Recorders, Audio players,Integrated systems in aircrafts and missiles Cellular telephones Electric and Electronic Motor controllers Engine controllers in automobiles Calculators Medical equipments Videogames Digital musical instruments, etc.
