Function of alu
WebThe ALU is a part of the CPU where various computing functions are performed on data. ALU performs arithmetic operations such as addition, subtraction, multiplication, division, and logical operations. The result of an operation is stored in internal memory of CPU. The logical operations of ALU promote the decision-making ability of a computer. WebDec 9, 2016 · An arithmetic logic unit (ALU) is a major component of the central processing unit of a computer system. It does all processes related to arithmetic and logic operations that need to be done on instruction words. In some microprocessor architectures, the ALU is divided into the arithmetic unit (AU) and the logic unit (LU). Advertisements
