has ~n/2 rows, the bit-array obtained by the simplification discussed here is
preferable to radix-4 recoding since it does not require recoding and multiple-
generation networks. Squarers for two's complement operand are obtained in a
similar manner.

Constant and Multiple-Constant Multipliers
If one of the operands of a multiplication is constant, the multiplication P = X x C
can be described by
P -- ~ X
X Cj
2 j 4.45
{jICj=I}
where the set {j } corresponds to all the ones' in the binary representation of C.
Consequently, the number of rows of the bit-matrix is reduced ...
