AbstractThe CMOS technology scaling is leading to the integration of ever more complex systems on silicon. On the other hand, the shrinking of the devices and the reduction of the supply voltage have significantly increased the static power dissipation, that in power budgets of nanometer technologies, cannot be neglected any longer.
In this work, we take advantage of the properties of the Residue Number System (RNS) to implement FIR filters with reduced static and dynamic power consumption. The results show that the RNS filters offer a reduction of 50% in static power dissipation and a total power reduction of 40\% with respect to the corresponding conventional filters.
