Data A
Data B
Each multiplier operand can be a unique signed or unsigned number.
Two signals, signa and signb, control the representation of each
operand respectively. A logic 1 value on the signa signal indicates that
data A is a signed number while a logic 0 value indicates an unsigned
number.

signed if any one of the operands is a signed value.
