Abstract

Symbolic substitution (S.S.) is a parallel technique for pattern replacement within a binary array. S.S. can be used in optical architectures to perform many different operations^[1]. There are several different ways to implement hardware which performs S.S. operations. This paper presents four different optical architectures based on S.S., and the strengths and weaknesses of each architecture are analyzed. This paper will deal only with architectural issues, leaving the detailed issues of implementation to future studies.
