[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.

Switching algebra is easily visualized using ... gate passed as an input to the final AND of the circuit. The half adder now is: We can reduce the gate count considerably by introducing an XOR ...

In the latest technology developed by MicroAlgo, they have successfully implemented the FULL adder operation using CPU registers based on quantum gate computers. A FULL adder is a fundamental ...
