Multi-parallel convolvers

Abstract

A scheme for a convolver design, called a multiparallel convolver, that is based on concurrent processing of p adjacent samples that are input simultaneously to the p-parallel convolver is presented. The scheme uses p units, each of which receives the input samples and produces one convolution every p samples; these are called p-phase subconvolvers. The detailed design of the p-phase subconvolvers and of the whole p-parallel convolver is presented and discussed. The scheme can be used for both the bit-parallel and the bit-serial input presentation of each sample. The input sample rate of the p-parallel convolver is p times the sample rate of a standard (1-parallel) convolver implemented using the same integration technology. The number of components required by a p-parallel convolver is approximately p times the number of components required by a standard convolver.<>
