Abstract

A new Benes network control algorithm is presented. Unlike the original looping algorithm, the new algorithm is not recursive. In this algorithm (N x N) Benes network is viewed as a concatenation of two subnetworks SN1 and SN2. The first (log N - 1) stages of a Benes network correspond to SN1, and the remaining log N stages correspond to SN2. SN1 is controlled by a full binary tree of set partitioning functions, called a Complete Residue Partition Tree, and SN2 is bit controlled. The new control algorithm sets switches one stage at a time, stage by stage.
