This paper introduces four techniques for performing fast decimal addition on multiple binary coded decimal (BCD) operands. Three of the techniques speculate BCD correction values and use chaining to ...

Multipliers play a crucial role in signal processing systems and any improvement in their speed directly enhances the overall system performance. Traditionally, multipliers consist of two main ...
