1 March 1999Synthetic correlation-based modified signed-digit trinary logic processing
An optical implementation using a correlation technique for modified signed-digit (MSD) trinary logic processing is presented. In particular, a synthetic matched filter (SMF) correlator model is used to demonstrate the realization of the carry-propagation-free trinary MSD addition. It is shown that proper encoding of the MSD numerals are of utmost importance for the correlator model to work. The developed method is expected to have far-reaching application in the optical higher radix numeric and logic processing.
