ABSTRACT
The authors present a multiplication algorithm for low power
implementation of digital filters on CMOS based digital signal
processing systems. The algorithm decomposes individual
coefficients into two primitive sub-components. The
decomposition, performed using a heuristic approach, divides a
given coefficient such that a part is produced which can be
implemented using a single shift operation leaving another part
with a reduced wordlength to be applied to the coefficient input
of the hardware multiplier. This results in a significant reduction
in the amount of switched capacitance and consequently power
consumption. The algorithm has been used with a number of
practical FIR filter examples achieving up to 63% saving in
