Low-Area and High-Throughput Architecture for an Adaptive Filter Using Distributed Arithmetic

A high-performance implementation scheme for a least mean square adaptive filter is presented. The architecture is based on distributed arithmetic in which the partial products of filter coefficients are precomputed and stored in lookup tables (LUTs) and the filtering is done by shift-and-accumulate...
