Optimized MAC unit design

In this paper, a new multiplier design is proposed which reduces the number of partial products by 25%. This multiplier has been used with different adders available in literature to implement multiplier accumulator (MAC) unit and parameters such as propagation delay, power consumed and area occupied have been compared in each case. From the results, Kogg tone adder has been chosen as it provided optimum values of delay and power dissipation. Later, the results obtained have been compared with that of other multipliers and it has been observed that the proposed multiplier has the lowest propagation delay when compared with Array and Booth multipliers.
