On the Performance of Interleaved Memories with Multiple-Word Bandwidths

Past studies of the performance of interleaved memory systems are extended in this note by adopting a more general model that assumes a system of N memory modules, each of which is made up of b submodules.

Abstract

Past studies of the performance of interleaved memory systems are extended in this note by adopting a more general model. The model assumes a system of N memory modules, each of which is made up of b submodules. Successive memory addresses are assigned to sequential submodules, modulo Nb. For increased effective memory bandwidth a so-called conflict buffer of size L + 1 is assumed to exist for storing address conflicts.
