Abstract:An embedded system is any device controlled by instructions stored on a chip. These devices are usually controlled by a micro processor that executes the instructions stored on a read only memory(ROM) chip.
Embedded systems are computer systems that monitor, respond to, or control an external environment. This environment is connected to the computer system through sensors, actuators, and other input-output interfaces. It may consist of physical or biological objects of any form and structure. Often humans are part of the connected external world, but a wide range of other natural and artificial objects, as well as animals are also possible.
Embedded systems control engine management systems in automobiles, monitor home heating systems and regulate the quiet operation and the even distribution of laundry in washing machines. They are the heart of toys like Furby and Tamagotchi, of golf balls that cannot get lost and of gas pumps at gasoline stations that advertise nearby restaurants on video. Above all, state-of-the art communications equipment like WAP mobile telephones, MP3 players, set-top boxes and Net devices would not be possible without these powerful miniature brains.
