What is Control Unit(CU)?
CU stands for Control Unit. It is one of the fundamental parts of the CPU. The main work of the CU is to tell the most efficient method to work. It guides all the related operations to the individual parts of the processor. Some basic operation performed by it includes taking guidelines, controlling sequential execution, managing information stream in the correct course, directing and observing the time needed amid the preparing and taking care of different functions, etc. It controls the operations of the processor. It informs the ALU, I/O devices, and the RAM how to respond to the command that has been sent to the processor. A control unit directs the system and executes instructions entered by the user.
Functions of Control Unit(CU)
Below are some functions of CU.
- Controls how data is sent through the CPU’s various components.
- Receives and transmits control signals from other devices.
- Interprets commands, controls processor time, and regulates.
- Decode, fletch, carry out the order, and store the results, among other responsibilities.
- Interprets directions and directives.
Difference Between ALU and CU
The most essential component of a computer is the Central Processing Unit. It is popularly known as CPU. It is used to process instructions. The principal component of the CPU is the Arithmetic Logic Unit and Control Unit. In this article, we will learn what is the main difference between ALU and CU.
