Definition[]

In computing, an arithmetic logic unit (ALU) (also called arithmetic and logic unit) is a digital circuit that performs arithmetic and logical operations.

Overview[]

The ALU is a fundamental building block of the central processing unit (CPU) of a computer, and even the simplest microprocessors contain one for purposes such as maintaining timers. The processors found inside modern CPUs and graphics processing units (GPUs) have inside them very powerful and very complex ALUs; a single component may contain a number of ALUs.
