| Popis: | This letter proposes a new distributed arithmetic (DA) algorithm for low-power finite-impulse response (FIR) filter implementation. The characteristic of the proposed algorithm is that the FIR filters using the proposed algorithm do not need to employ two's complement representation in lookup tables as well as multiply-and-accumulation blocks. Thus, the proposed algorithm can minimize the dynamic power consumption of the FIR filters. The experimental results show that the lowpass FIR filter using the proposed algorithm achieves 29% and 26% power consumption reduction compared to that using the conventional algorithm for zero-mean random inputs and speech inputs, respectively. |
