The control unit of a microprocessor _________________.
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices on how to respond to a program's instructions.
The basic functionality of
the Microprocessor is to do processing. Microprocessor performs two type of
operations called Arithmetic and Logic. So the basic functionality unit which
consists of Arithmetic ( Addition, Subtraction, Multiplication & Division)
and Logic (AND, OR, NOT) is called Arithmetic Logic Unit.
The Central Processing Unit (CPU) is also known as the microprocessor or processor. The processor contains three sections called the Arithmetic Logic Unit (ALU), the Control Unit and Registers. Control unit: The Control Unit makes decisions and sends the appropriate signal down its lines to other parts of the computer.
