What is ALU?

Find out about this building block of computing circuits.

By Vinod

In computing, an ALU (Arithmetic Logic Unit) is a digital electronic circuit which conducts operations on binary numbers in arithmetic and bitwise logical ways.

The latter operates on binary numbers in terms of individual bits whilst numbers are covered through the arithmetic processes.

ALU is classified as combinational logic which means that the output is solely dictated by the present input only. Sequential logic in comparison can register both past and present logic in sequence. Therefore, the output of the ALU will change as the input changes in synchronisation.
