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).

  6. A network is nonblocking if, regardless of what state the network is currently in, any pair of idle input–output terminals can be connected without having to reroute any existing connections.
  7. A network is called a rearrangeable network if it can perform all possible connections between inputs and outputs by rearranging its existing connections. However a rearrangeable network can still be blocking.
