An Analysis of Processor-Memory Interconnection Networks

An interference analysis of the interconnection networks (IN´s) for tightly coupled multiprocessors is presented in this correspondence. The interconnections considered are crossbars and delta networks. Two situations are examined: when a memory module is equally likely to be addressed by a processor and when a processor has a favorite memory. It is shown that for a higher rate of favorite requests, the delta networks perform close to a crossbar.
