What is Arithmetic Logic Unit(ALU)?
ALU stands for Arithmetic Logic Unit. It is a very essential part of the CPU. It performs all the basic arithmetic (addition, subtraction, multiplication, and division) operations and logical operations. The ALU typically designed in such a way that it has direct input and output access to the random access memory (RAM). In modern computers, the ALU is itself is divided into two categories:
- Arithmetic Unit (AU)
- Logic Unit (LU)
Functions of ALU
Below are some functions of the Arithmetic Logic Unit(ALU).
- Input operands, adding operands, accumulated results, and shifting results can all be stored in the ALU.
- ALU subunits carried out gated circuits regulate the flow of data and the operations. A series of adding, subtracting, and shifting operations are used for division and multiplication.
- It performs arithmetic operations like addition, subtraction, multiplication, and division operations also it performs logical operations.
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.
