Arithmetic Logic Unit


An Arithmetic Logic Unit (ALU) is a digital circuit that performs arithmetic and bitwise logical operations on binary numbers. It is a fundamental building block of the central processing unit (CPU) of a computer. The ALU performs operations such as addition, subtraction, multiplication, division, and logical operations such as AND, OR, NOT, and XOR. The ALU takes two binary inputs and produces a binary output based on the operation performed. The ALU is designed to perform these operations quickly and efficiently, using a combination of hardware and software techniques. The ALU is an essential component of any computer system, and its performance is critical to the overall speed and efficiency of the system.
