Abstract

We discuss our cascaded correlator-based optical numeric processor and its projected performance (our goal is a numeric processor and not a general-purpose optical processor). We use symbolic substitution (for parallelism on long words and arrays of words), the modified signed-digit number representation (for speed, i.e. reduced carries), and a new encoding and substitution architecture to improve performance.
