We read in newspapers that a doctor had successfully transplanted a cardiac pacemaker in his patient’s chest by sitting around 200 kilometres away. Also we know about driverless cars that could take us to the destiny by using its inbuilt navigation systems. Embedded microprocessors or micro controllers are the brain behind these.
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.
IN THE DRIVING SEAT
There are several tasks in which real time OSs beat their desktop counterparts hands-down. A common application of embedded systems in the real world is in automobiles because these systems are cheap, efficient and problem free. Almost every car that rolls off the production line these days makes use of embedded technology in one form or the other.RTOSs are performed in this area due to their fast response times and minimal system requirements.
Most of the embedded systems in automobiles are rugged in nature, as most of these systems are made up of a single chip. Other factors aiding their use are the low costs involved, ease of development, and the fact that embedded devices can be networked to act as sub modules in a large system. No driver clashes or ‘system busy’ condition happen in these systems. Their compact profiles enable them to fit easily under the cramped hood of a car.
