The Graph Search Machine (GSM): A VLSI architecture for connected speech recognition and other applications.

A new architecture is proposed for efficiently computing a variety of kernel operations for many speech recognition functions. The essential elements of this architecture are a fast accumulator- minimum selector and a writable control store. Using a single GSM, real time connected word recognition of 500 templates is possible. Parallel GSM configurations are easily made for larger vocabularies. The architecture supports other applications including string matching, character recognition and sorting. A low cost single chip VLSI design is under way using 1.75micron custom logic.
