1. A system for pattern recognition comprising:

  • a receiving means receiving a sequence of signals configured in a signal array, including signals denoting an overall pattern;

    a configuring means for configuring said signal sequence into a plurality of signal sub-arrays, each of said signal sub-arrays responding to a portion of said overall pattern;

    a hashing means for mapping each of said digital pattern signal sub-arrays to an address in an associated memory having a set of stored signals corresponding to possible overall patterns;

    a return means for retrieving said possible overall pattern signals from each of said mapped addresses; and

    a combining means for combining said retrieved possible overall pattern signals and generating therefrom identification signals indicative of the overall pattern unanimously indicated by the combination of all of said retrieved possible overall pattern signals.
