Abstract
In this work we discuss the realization of constant multiplication using a minimum number of carry-save adders. We consider both non-redundant and carry-save representation for the input data. For both cases we present all possible interconnection topologies, using up to six and five adders, respectively. These are sufficient to realize constant multiplications for all coefficients with a wordlength up to 19 bits.
