Abstract
The interconnection network is the key for parallel processing which has been shown to be a fast way to process information. Especially, regular interconnections need a very low space product, so the free-space regular interconnections become the important interconnecting network for the development of massively parallel architectures. One of the most useful and universal regular interconnections is the perfect shuffle.1 it is probably the most used in multistage-interconnection networks, and some other networks can be recast into it. Different combinations of perfect shuffle and exchange box networks also are effective for some algorithms. Some optical perfect shuffle networks have been developed in recent years2–4 and these networks have both advantages and faults. In this paper we propose an optical correlation method for implementing this kind of interconnection, and Fig. 1 depicts the architecture for the optical perfect shuffle.
