An
example of multiple-constants multipliers.
the use of common subexpressions leads to further reductions in the number of
adders, compared to implementation using separate constant multipliers. 9 The
following example illustrates such a case.
EXAMPLE
4.5
Consider the simultaneous computation of P1 = 9X, P2 = 13X, P3 = 18X,
and P4 -" 21X.
An implementation using separate constant multipiers requires six
adders. By decomposing the products as ...
