An Adder-Segmentation-based FIR for High Speed Signal Processing

An advanced adder-segmentation-based FIR filter design for high speed signal processing is proposed in this paper. In the proposed method, the critical path delay is shortened through adder segmentation. An analysis for the optimization of adder segmentation is also proposed, which can be used for critical path delay balance to maximize the performance of FIR filters. The evaluation results show that the proposed design can achieve up to 30.7% and 22.8% reduction in area-delay-product (ADP) and energy-delay-product (EDP) when compared with the existing FIR filters.
