Variable Truncated Multiplier with Low Power

Multipliers play a significant part in the DSP architecture. Truncation helps in the reduction of power consumption by disabling a portion of the partial  product. In this paper different multipliers are made to truncate the partial  products variably using a control bit and then compared for power and delay. The comparison results show that the Dadda multiplier shows a  small improvement in power and Baugh Wooley is better in terms of delay.
