Program behavior and the performance of interleaved memories

[摘要] One of the major factors influencing the performance of an interleaved memory system is the behavior of the request sequence, but this is normally ignored. This report examines this issue. Using trace driven simulations it is shown that the commonly used assumption, that all requests are equally likely to be to any module, is not valid. The duality of memory interference with paging is noted and this suggests the use of the Least-Recently-Used Stack Model to model program behavior. Simulation shows that this model is quite successful. An accurate expression for the bandwidth is derived based upon this model.
