Because
NCL is a uniform and consistent logic, the NCL
version of the same DIMS circuit can be optimized.
Figure 28 is the NCL version of the DIMS full
adder.

The DIMS full adder counterpart can be optimized
to the full adder circuit shown in Figure 29 with
expression transforms entirely within the context
of NCL.

Full adder circuits can be combined in the evident
way to form a ripple carry adder as shown in Figure
30.
