Abstract
The authors present a number of low power FIR filter
implementations. The implementations are based on processing
coefficients in a non-conventional order using both direct form
and transpose direct form realisation of FIR filters. The paper
describes the overall filter architecture of each implementation
and their key components. An overall power reduction of up to
34% is reported as compared to a conventional filter
implementation. A power profile of the main contributing
components in each implementation is also provided.
1. Introduction
One of the fastest growing areas in the computing industry is
