What is CPU?
Central Processing Unit (CPU) controls the all
operation of the computer. It is also called the
Brain of the computer and System Unit.
The CPU is responsible for handling all
instructions it receive from hardware and
software running on the computer.
• The brain of a computer system where
calculations and decisions are made.
• The main part of the computer that manages,
stores and use data.
Components of CPU
Two main components
Arithmetic logic unit
Control unit
Other components
• Register
• Cache
….etc
ALU ( Arithmetic logic Unit)
• The unit that performs arithmetic operations such as
addition, subtraction, multiplication.
• The unit performs logic instructions such as comparison
( AND, OR and NOT operations )
• ALUs are designed to perform integer calculations.
FPU ( Floating Point Unit )
• ALUs typically do not perform division operations, as the
result may b a “ floating point” numbers.
• Division operations are usually handled by the FPU.
