A class of interconnection networks based on some existing permutation networks is described with applications to processor to memory communication in multiprocessing systems. These networks, termed delta networks, allow a direct link between any processor to any memory module. The delta networks and full crossbars are analyzed with respect to their effective bandwidth and cost. The analysis shows that delta networks have a far better performance per cost than crossbars in large multiprocessing systems.
