This is the groundwork for the half adder . The next step is the operational logic, which of course falls upon macros: /* Full adder macros */ /* Out = (A ^ B) ^ cin */ #define FULL_ADD_OUT( a ...

making it feasible to construct any type of complicated logic IC reliably. In addition, more complex functional units such as a full adder, and MUX and DEMUX circuits are successfully demonstrated ...
