Microprocessor is an electronic circuit that is based on integrated chip IC. Microprocessor has all the functions of a Central processing Unit (CPU) of a computer. It either used single chip for that or multiple chips are also used. Microprocessors are a multi-purpose device. It performs three functions – accepts digital data as input, processes the data and stores it in the storage devices – registers and gives the output. First commercial microprocessor was developed by Intel in 1960's and it was a 4 bit microprocessor. Microprocessor performs with three main steps fetch, decode and execute methods. Use of microprocessor is not limited to a particular area instead it is has diverse applications. They include small and large scale applications. Some of them are discussed below:
Used in cars that is in its accessory parts, in toys, test instruments, computers.
Finds applications in electrical circuit breakers, switches, smoke alarm battery, radio.
Devices like – DVD player, cell phones other audio-visual components use microprocessors.
Broadcast systems, satellite communication, automotive, home security systems also use microprocessor.
Also used in washing machines, i-pod, remote control and other electronic devices.
Microprocessors are ICs so they find applications in household items like refrigerator, microwave ovens, cell phones , others.
Aerospace vehicles , nuclear reactors and also in some instruments like – function generators, frequency counter and spectrum analyzers.
Digital cameras, lifts, remote control cars, games console, traffic light system all uses microprocessors for their functioning.
