Multiple constant multiplication (MCM) has been shown to be an efficient way to reduce the number of additions and subtractions in FIR filter implementations. However, for polyphase decomposed FIR filters and filter banks, the problem can be formulated in three different ways. Eitheras one MCM block with all coefficients, one MCM block for each subfilter, or as a matrix MCM block. In this work we compare the approaches in terms of complexity, both for the MCM blocks and for the remaining hardware, suchas structural additions and delay elements.
