Paper Abstract

Symbolic substitution was firet proposed by Haung as a mean of utilising the parallelism of optics to perform digital computing. Essentially, it is a combination of recognition and substitution phase. In addition, although synibolic substitution is not restricted to space invariant operations, it is indeed based on the space invariant connectivity of optics. Therefore, holographic associative memory techniques may be alternatively applied to implement a symbolic substitution logic system.
