<p>For memory bandwidth analysis, researchers generally discard requests that are notaccepted during a memory cycle. This assumption simplifies the analysis and producesnegligible discrepancies with actual results for a system with a non-hierarchicalinterconnection network. However, the assumption, "the requests that are not occupiedduring a memory cycle are discarded," cannot be used for a multiprocessor system with ahierarchical interconnection network (HIN), because the error introduced assumption canbe several orders of magnitude higher than the actual bandwidth. An improved analyticalmodel to determine the bandwidth of a HIN-based system is presented.</p>
