Two possible forms of numerical truth-table look-up processors using content-addressable optical holographic memories are presented. Application of these processors to performing numerical calculations in direct binary and in binary-coded residue number systems is discussed. Specific examples of the number of input and output bits required and the number of truth-table combinations holographically recorded for computation in both numerical systems are given. Truth-table look-up processing using binary-coded residue is shown to require the recording of dramatically fewer reference patterns than direct binary.
本文介绍了两种使用内容可寻址光学全息存储器的数字真值表查找处理器的可能形式。讨论了这些处理器在直接二进制和二进制编码余数系统中进行数值计算的应用。给出了在这两种数值系统中进行计算所需的输入和输出位数以及全息记录的真值表组合数的具体示例。结果表明，使用二进制编码余数的真值表查找处理所需记录的参考模式比直接二进制要少得多。
