[Phillip] wanted to play with the C preprocessor. He decided to do that by creating a 4 bit full adder. We know this is pretty useless in everyday life, but it was a great learning experience.

Now we have the final full adder circuit design. As nice as this design appears, it is not practical as an accumulator, e.g. a register for adding many bits at one time. If you want to add a 32 ...

An elementary electronic circuit in the arithmetic logic unit (ALU) of the CPU that adds one bit to another. The output of the half-adder is a result of 0 or 1 and a carry of 0 or 1. Additional ...

A FULL adder is a fundamental arithmetic unit in classical digital circuits, used to perform the addition of two or more binary numbers. In classical computers, the design and implementation of a FULL ...
