Definition of microprocessor:
Computer’s Central Processing Unit (CPU) built on a single Integrated Circuit (IC)
is called Microprocessor.
A digital computer with one microprocessor which acts as a CPU is called
microcomputer.
A microprocessor is a multi-purpose, programmable, clock-driven, register based
electronic device that reads binary instruction from storage device called memory
accepts binary data as input and process data according to those instructions and
provide result as output.
Microprocessor acts as CPU in microcomputer. It is present as single IC chip in
microcomputer.
Application of microprocessor:
1. Control Unit for home appliances:
Microwave oven, Washing Machine, Refrigerator, heating system, air
conditioner.
2. Control System for computer peripherals:
Disk driver, Printer, keyboard, Modems.
3. Traffic control system:
Road, air and ocean traffic navigation system
4. Machine Control System:
Robotics, Mobile, Automated guided Vehicle (AVG).
5. Production System:
Assembly line Packing system etc.
Features of Microprocessor:
- Low Cost: Due to integrated circuit technology MP are available at very
low cost. It will reduce cost of a computer system.
- High speed: Due to technology involved in it, the microprocessor can work
at very high speed. It can execute millions of instructions per second.
