Introduction To Embedded Systems

A System is a method of organizing and doing one or more specific tasks according to a pre-defined plan or a set of rules. An Embedded system is a computer system, that is a combination of a computer processor, computer memory, and input and output peripheral devices, that has a dedicated function. An Embedded system is a system of hardware and software designed to perform dedicated functions with a large electrical or mechanical system. It can work either as an independent system or as a part of a large system. The Embedded systems are electronic systems that have software and hardware for a dedicated application or for the specific part of an application. An embedded system consists of embedded hardware, the main application software, and a real-time operating system (RTOS) to supervise the application software.

Embedded systems have many applications in consumer, industrial, automotive, home appliances, medical, commercial, and military equipment. Some of the familiar systems that use embedded systems are MP3 players, television sets, mobile phones, video game consoles, digital cameras, GPS receivers, and printers. Your household appliances like microwave ovens, washing machines, and dishwashers have an embedded system to provide flexibility and efficiency to the system.
