Processor

A microprocessor is a small chip that serves as the Central Processing Unit (CPU) of a computer, executing program instructions. Key components of a CPU include an electronic clock, control unit, arithmetic logic unit (ALU), floating point unit (FPU), and various registers. CPU performance is measured in GHz, with examples of processors including Intel Core Duo and Intel Core i7.

CPU STANDS FOR

CENTRAL PROCESSING UNIT


THE CPU (CENTRAL PROCESSING UNIT) IS THE
‘BRAINS’ OF THE COMPUTER.

THE PURPOSE OF THE CPU IS TO CARRY OUT


PROGRAM INSTRUCTIONS (EACH CPU TYPE IS
DESIGNED TO UNDERSTAND A SPECIFIC
GROUP OF INSTRUCTIONS, THE INSTRUCTION
SET).

ON PERSONAL COMPUTERS AND SMALL


WORKSTATIONS, THE CPU IS HOUSED IN A
SINGLE CHIP CALLED A MICROPROCESSOR.
There are huge variations in CPU designs but most will share the
following key components:
▪ An electronic clock
▪ The control unit
▪ An instruction unit which consists of:
▪ The arithmetic logic unit (ALU)
▪ The floating point unit (FPU
▪ Various registers such as the accumulator.
▪ Various buses
▪ The bus management unit
▪An instruction unit consists of:
▪ The arithmetic logic unit (ALU) which executes basic arithmetic
and logical operations on integer data that it is linked to. Examples
of such operations include:
▪ Integer arithmetic operations (addition, subtraction)
▪ Logic operations (AND, NOT, OR, XOR)
▪ The floating point unit (FPU) which performs math functions on
floating point numbers (non-integer numbers).
▪ Various registers such as the accumulator that are used while
instructions are being executed.
