Abstract

A 2-D optical three-stage Clos interconnection network, which is made up of a number of feasible crossbars of medium size, is implemented for dynamic data communications. The network is nonblocking and can handle a large number of communication lines (compared with crossbar networks of realizable size). Both one-to-one and one-to-many routing algorithms are discussed. Applications based on the Clos network are proposed for SIMD (single instruction multiple data) parallel computations and four-level programmable logic arrays (PLAs).
