The use of a holographic content-addressable memory system for parallel truth-table look-up digital data processing is analyzed. For binary-coded residue numbers, the operations of 4-, 8-, 12-, and 16-bit addition and multiplication are treated. The minimum probability of error that can be achieved and the corresponding detector threshold settings are determined in each case allowing for the effects of Gaussian distributions in the amplitude and the phase in the recording beams. Resultant probabilities of error for practical conditions are found to be very competitive with those from state-of-the-art nonparallel technologies.
分析了全息内容可寻址存储系统在并行真值表查找数字数据处理中的应用。对于二进制编码的余数，处理了4位、8位、12位和16位的加法和乘法运算。考虑到记录光束中幅度和相位的高斯分布影响，分别确定了每种情况下可实现的最小错误概率以及相应的探测器阈值设置。发现实际条件下的最终错误概率与最先进的非并行技术相比具有很强的竞争力。
