Abstract
Previous studies on the performance of crossbar multiprocessor systems have assumed a uniform memory reference model. Hot-spots arising in m ultiprocessor systems due to the use of shared variables, synchronizat ion primitives, etc. give rise to nonuniform memory reference pattern. This paper presents an analytical expression for calculating the aver age memory bandwidth of a crossbar multiprocessor system having a hot memory. The expression is verified by simulation results.
