It is the electronic circuit that functions as the CPU of computer and provides computational control. They are also used in advanced electronic systems such as printers, automobiles etc. The microprocessor is one of the type of ultra large integrated circuit. The modern microprocessor consists of transistors which act as a electronic amplifier, oscillator, or switches in addition to other components such as registers, diodes, capacitors and wires. All these components are packed into an area having the size nearly a postage stamp.
The microprocessors consists of several different sections:
-The arithmetic/logic unit(ALU) performs several calculations on numbers and makes logical decisions.
-Registers are memory locations which stores the temporary information's.
-The control unit(CU) deciphers the programs.
-Buses carries digital information through out the chip and computer.
-Local memory is used for on-chip computations.
-Cache memory is used to speed up data access on external storage devices.
The modern microprocessor uses the bus width of 64 bits i.e 64 bits of date can be transferred at a time. The crystal oscillator of the microprocessor provides clock signal to coordinate the activities of the microprocessor. The clock speed in the microprocessor allows billions of instructions to be executed every second.
