Paper Abstract

In this paper, we propose a digital optical arithmetic processor design based on symbolic substitution using holographic matched and space-invariant filters. The proposed system performs Boolean logic, binary addition and subtraction in a highly parallel manner, i.e., the processing time depends on the word size but not on the array size. A skew problem occuring when symbolic substitution is applied to binary addition and subtraction with space-invariant systems is addressed and its solution is suggested. Crosstalk in symbolic substitution is described and new symbols which can prevent the crosstalk are introduced. System analysis and fundamental limitations of the proposed system are also presented.
