Abstract [en]

Multiple constant multiplication (MCM), i.e., realizing a number of constant multiplications using a minimum number of adders and subtracters, has been an active research area for the last decade. Almost all work has been focused on single rate FIR filters. However, for polyphase interpolation and decimation FIR filters there are two different implementation alternatives. For interpolation, direct form subfilters lead to fewer registers as they can be shared among the subfilters. The arithmetic part corresponds to a matrix vector multiplication. Using transposed direct form subfilters, the registers can not be shared, while the arithmetic part has the same input to all coefficients, and, hence, the redundancy between the coefficients is expected to be higher. For decimation filters the opposite holds for direct form and transposed direct form subfilters. In this work we discuss the trade-off between adders/subtracters and registers, and present implementation results for area, speed, and power for different realizations
