Low Power and High Speed Dadda Multiplier using Carry Select Adder with Binary to Excess-1 Converter

As the digital electronic systems are getting better with the advancement in technology day by day; there is a need to build faster and more power-efficient multipliers, which are the major building block in most of the digital processing systems. Dadda tree multiplier is one of the effective multipliers consuming low power and quite faster than other multipliers i.e. Vedic, Wallace and booth redix4 multiplier. In this paper, we have designed a Dadda tree multiplier with carry select adder followed by binary to excess-1 converter which makes it much faster and power efficient. The results for this multiplier are comparatively better considering other existing multipliers.
