Abstract

The authors analyze and evaluate the performance of arrangements of data to be processed in digital optical parallel computing. The authors categorize the ways to arrange the data into two options. One is the spatially expanded bit-pattern arrangement, and the other is the bit-slice one. The arrangements are applied to parallel operations based on the optical array logic (OAL). To evaluate the performance, the number of encoding, that of discrete correlations, that of input images, the size of cluster, and that of shift in digital discrete correlations in OAL are analyzed in case of applying each arrangement. Several guidelines to choose the arrangement for effective implementation of parallel operations are clarified.
