The Proposed Full-Dadda Multipliers

Vikas Kaushik*, Himanshi Saini

Dadda multipliers require less area and are slightly faster than Wallace tree multipliers. Among tree multipliers, Dadda multiplier is the most popular multiplier. This paper presents a new tree multiplier named Full-Dadda which has a new reduction scheme. This novel reduction scheme results in less number of bit-interconnects and less interconnect area than those in Dadda multiplier. This proposed reduction scheme is also a superior one in terms of regularity, simplicity and alternative use. This regularity and simplicity do not require any extra hardware. The comparative performance analysis of the Dadda and the Full-Dadda multipliers with different operand sizes is presented in this paper. Figures and tables are given to illustrate above advantages of the proposed multiplier.
