Paper Abstract

Optical systems capable of performing arithmetic operations in parallel on arrays of binary input data are discussed. Data obtained from the truth-tables for the implemented operations are stored as holograms used in the systems. These data (or their reduced form) correspond to either the sum of products or the product of sums logical expressions relating each of the bits of the result to the input bits. Using the operations of addition and multiplication as examples it is shown that the number of holograms that must be recorded is considerably reduced when the input and output data are in binary-coded residue representation rather than in direct binary representation.
