GENERALIZED DIGITAL MULTIPLIER AND DIGITAL FILTER EMPLOYING THE MULTIPLIER

摘要

P Generalized numerical multiplier and digital filter implementing it. / P P The multiplier of the invention comprises N shift registers RD0,..., RDN-1 containing the words xi on B bits, N ADCO conditional adders, ..., AdCN-1 each adding to the partial sum they receive a constant coefficient ai, conditionally to the value of the bit xi ,, j they receive from the associated register RDi, and an adder -accumulator AdAc. The digital filter using such a multiplier further comprises an input register, parallel words. / P P Application to digital filtering. / P
