Description: An arithmetic logic unit is a combinational digital electronic circuit that performs arithmetic and bitwise operations on integer binary numbers. This is in contrast to a floating-point unit , which operates on floating point numbers. An ALU is a fundamental building block of many types of computing circuits, including the central processing unit of computers, FPUs, and graphics processing units . A single CPU, FPU or GPU may contain multiple ALUs. The inputs to an ALU are the data to be operated on, called operands, and a code indicating the operation to be performed; the ALU's output is the result of the performed operation. In many designs, the ALU also has status inputs or outputs, or both, which convey information about a previous operation or the current operation, respectively, between the ALU and external status registers.
