Arithmetic logic unit
In computing, an arithmetic logic unit (ALU) is a digital circuit that performs arithmetic and logical operations. The ALU is a basic building block of the central processing unit (CPU) of a computer, even the simplest microcontrollers contain one for purposes such as timing.
Mathematician John von Neumann proposed the ALU concept in 1945.
