Abstract
A processor for generating a Walsh transform by computing M combinations of M input values ??substantially simultaneously where M = 2 ? N ? and the input values ??are twos complement binary values has N stages electrically connected in series each stage having a cross network of M electrical conductors in a predetermined pattern connected to a set of M / 2 butterfly circuits the butterfly circuits having means for calculating sums and differences through their corresponding cross networks of submitted values ??and submit the sums and differences to corresponding ladders of the cross network of the next stages. The input values ??are presented to the first-stage cross-network serially and with the least significant bits first and substantially simultaneously with this the Walsh transform of the input values ??is serially generated by the N-th stage butterfly circuits.
