Full Adder Architecture-- Notes Page -- |
A one-bit full adder will be used in the next few pages as an ongoing
example.
One way to describe the function of a full-bit adder is as a look-up
table. In other words, we can define every mapping of the inputs to
the outputs, and encode them as a case statement in the body of the
process. Here, the logic tables used to generate the outputs,
Sum and Cout, are shown.
