Embedded computer system

Embedded computer system is a device which consists of a programmable computer. Examples are fax machines built using a microprocessor. A microprocessor is a single chip CPU (central processing unit). Automobile industry is using microprocessors to control the engine. Microcontrollers were designed later which includes memory and input/output peripherals. For computation-intensive applications, RISC microprocessors are used which 32-bit microprocessors are offering superlative performance. Embedded microprocessors are extensively used in digital television. An antilock brake system (ABS) which reduces skidding of vehicles was developed by embedded computer technology by BMW which is known as BMW 850i. Here an automatic stability control system arbitrates the engine. In an embedded computer system, complex algorithms required. This requires sophisticated user interfaces like global positioning system. Embedded computer system performs in real time and assumes multirate behavior. While designing an embedded computer system, manufacturer should take special care in lowering power consumption and manufacturing cost.
