Abstract

In this paper, we present a new method for the implementation of pipelined finite impulse response (FIR) adaptive digital filter (ADF). The proposed method reduces the length of the critical path, while simultaneously limiting the latency and the maximum delay of the coefficients of the FIR ADF to two and a fourth of the order of the filter, respectively. The latency of the proposed method is also independent of the order of the filter. Furthermore, since the FIR filter portion of the ADF incorporates only a single delay element, the proposed pipelining method can also be applied to pipelined IIR ADF
