Abstract: The work portrays about the design of the Dadda multiplier using 4:2 compressor techniques. The three design techniques, namely conventional design, optimized design using exclusive OR with multiplexer and a further optimized design with less number of critical paths with gates are implemented. All the three designs are implemented in Dadda multiplier and wallace tree multiplier and their performances are compared. The performance metrics measured are area, power consumption, delay and transistor count and these parameters are efficient in dadda multiplier compared to wallace tree multiplier with the above three design techniques. The designs are using behavioral modeling and the results are taken in the 180nm Cadence tool. The result shows that the Dadda multiplier performs better in terms of delay, area and transistor count for all three designs than the Wallace tree multiplier.
