Abstract
Presentation of an efficient architecture for the implementation of a delayed least mean square adaptive filter. For achieving lower adaptation-delay and area-delay-power efficient implementation, we use a novel partial product generator and propose a strategy for optimized balanced pipelining across the timeconsuming combinational blocks of the structure. From synthesis results, we find that the proposed design offers less area-delay product (ADP) and less energy-delay product (EDP) than the best of the existing systolic structures. An efficient fixed-point implementation scheme of the proposed architecture, and derive the expression for steady-state error shows that the steady-state mean squared error obtained from the analytical result matches with the simulation result.
