摘要
本文讨论了对输入图形进行特定的编码和对器件采用不同的读写模式。仅用单个 BSO—PROM(Bi_(12)SiO_(20)单晶普克尔效应光读出器件)便实现了两个二值图形间的所有 Boolcan 逻辑,而且不需要时序地改变器件的外加电压(极性和大小),从而大大提高了 PROM 用于光逻辑运算的速度。还将这种 PROM 成功地用于光学符号代换、矩阵外积及互连网络之中。
A special coding for input patterns and different read/write modes for BSO-PROM(Pockel's read-out optical effect modulator) are discussed.Only a single BSO-PROM device is needed to realize all the Boolean logic between two binary patterns.The sequential changes of the bias voltage (polarity and amplitude) are avoided,so that the logic operation speed with PROM is greatly raised.The applications of BSO-PROM for OSS (optical symbolic substitution),MOPC(matrix outer product calculation) and NI (network interconnection) are also implemented.
