In this brief, we present a digital based reconfigurable finite impulse response (FIR) filter architecture. It provides flexible and low power consumption to the FIR filters with wide range of accuracy and tap length. The approach is well suited when the filter order is fixed and not changed for particular applications, and efficient trade-off between power savings and filter performance can be made using the proposed architecture. Generally, FIR filter has large amplitude variations in input data and coefficients. Considering the amplitude of the filter coefficients and inputs, the proposed FIR filter dynamically changes the filter order.
