Short for Arithmetic Logic Unit, the ALU is a complex digital circuit with an AU (Arithmetic Unit) and a LU (Logic Unit). Multiple Arithmetic Logic Units are in a computer, including multiple ALU's in the CPU (Central Processing Unit), GPU (Graphics Processing Unit), and FPU (Floating-...
The arithmetic/logic unit (ALU) handles all arithmetic operations and logical operations. Its math functionality is based on four types of operations (addition, subtraction, multiplication and division). Logical operations typically involve some type of comparison (such as of letters, numbers or specia...
Typically, the ALU has direct input and output access to the processor controller, main memory (random access memory orRAMin a personal computer) andinput/outputdevices. Inputs and outputs flow along an electronic path that is called abus. The input consists of an instruction word, sometimes cal...

The main components of a CPU are the ALU, registers and control unit. The basic functions of the ALU and register are labeled in the above “basic elements of a processor section.” The control unit is what operates the fetching and execution of instructions. ...
While the ALU is a fundamental component of allprocessors, the design and function of an ALU may vary between different processor models. For example, some ALUs only perform integer calculations, while others are designed to handle floating point operations as well. Some processors contain a single...
