ABSTRACT
The paper proposes a hierarchical algorithm for low power
implementation of digital filters. The algorithm processes data and
coefficients in blocks of fixed sizes. During the manipulation of each
block, coefficients are segmented into two primitive components.
The accumulative effect of processing a sequence of blocks and
segmentation results in up to 80% reduction in power consumption
compared to conventional filtering. The paper describes the
implementation of the hierarchical algorithm, its constituent
components and the power evaluation environment developed.
Results are provided which demonstrate the effectiveness of the
