N2 - Digital Signal Processing (DSP) often involves multiplications with a set of coefficients. This paper presents a novel multiplier design methodology for performing these coefficient multiplications with very low power dissipation. Given bounds on the throughput and the quantization error, our approach scales the original coefficients to enable the partitioning of each multiplication into a collection of smaller multiplications with shorter critical paths. Significant energy savings are achieved by performing these multiplications in parallel with a scaled supply voltage. Dissipation is further reduced by disabling the multiplier rows that do not affect the multiplication's outcome. We have used our methodology to design a low-power parallel multiplier for the Fast Fourier Transform. Simulation results show that our approach can result in significant power savings over conventional multipliers.
