Detailed explanation-1: -What Is an ALU? An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs.
Detailed explanation-2: -The arithmetic logic unit is split into AU (arithmetic unit) and LU (logic unit). The operands and code used by the ALU tell it which operations have to perform according to input data. When the ALU completes the processing of input, the information is sent to the computer’s memory.
Detailed explanation-3: -relation to central processing unit The ALU carries out basic arithmetic and logic operations, and the control section determines the sequence of operations, including branch instructions that transfer control from one part of a program to another.
