+--bitser.primatives.slice.SubtractorSlice
Implements a subtraction for two LSB (Least Significant Bit) first, signed, serial data inputs within a ser-by-parallel CSD coded multiplier.
The control signal must be asserted HI during the LSB to ensure proper reseting of the core for the next data word.
