用解析模型对单总线多处理器系统进行性能评价

The Performance Evaluation of the Single Bus Multiprocessors with Analytic Models

性能评价是选择、改进和设计计算机系统的一个重要方面。本文给出了两种不同的、且均带公用存储器的单总线多处理器体系结构，并通过解析模型分析和比较了竞争物理共享资源（全局总线和公用存储器）对两种体系结构性能的影响。

The performance evaluation is important in selecting,improving and designing a computer system. In order to study the effect of the contention for the physically shared resources (buses and memories) on the performance with analytic models, two different common memory organizations corresponding to two multiprocessor architectures are analyzed and compared in this paper.
