PROCESSOR

            It is the central processing unit of the computer. It does all the operations of the computer. This is considered like a brain of the computer. All the data’s are available in the form of binary code that is inside the processor.

       ARCHITECTURE OF PROCESSOR

*  CISC [complex instruction set computer]

*  RISC [reduced instruction set computer]

  1. CISC

Every olden processor has this type of architecture. In this the pins are available in the processor and the holes are available in the processor socket. It contains 728 pins

  1. RISC

All the new processor has this kind of architecture. The pins area available on the processor socket and the dots are available on the processor. It contains 478 pins.

FUNCTIONAL UNITS/ PARTS OF THE PROCESSOR

  • ALU
  • CU
  • Floating point unit
  • Core
  • Cache memory
  • Bus interface

ALU

            This is used to perform arithmetical and logical calculations.

CU

            This is used to control all the operations of the computer.

Floating point unit

            This is used to perform only the decimal number calculation of the processor.

CORE

This is the important unit of the processor. It’s used to read the instruction from the input devices and it gives to other units according to the function. It receives the output from the other unit and it executes to the user.

Cache memory

            It’s a small bit of memory which is available in the processor. This is used to increase the speed of the processor.

Bus interface

            This is used to transfer the data
