The order of precedence is less well defined for logic circuits ... Let’s apply switching algebra to the design of a half adder, a core circuit in CPUs. A half adder takes two binary inputs ...

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 ...

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 ...
