一种分析缓存优化下mesh延时与吞吐量性能的数学方法

A mathematical method for analyzing the latency and throughput of mesh with buffer optimization

片上网络被广泛讨论用于解决大规模片上系统的互连问题。为了满足一定的应用,分析片上网络的性能是必需的。对片上网络的性能分析需要高效而精确的数学分析方法,从而弥补利用系统仿真进行性能分析的低效率。因此本文针对缓存优化下单虚通道的mesh结构提出了一种基于概率分析的数学方法来求其在XY路由下的平均延时及最大吞吐量性能,最后利用系统仿真验证了此方法的准确性。

Network-on-Chip （NoC） is widely discussed to solve the interconneeuon prom^m u s ~ To meet a certain application, performance analyses of NoC are necessary. It needs an efficient and accurate method to analyze the performance because of the inefficiency of system simulations. Thus this paper proposes a probability analysis based mathematical method for mesh with buffer optimization and single virtual channel, it computes the average latency and the maximum throughput of mesh with XY routing, and the accuracy of the method is proved by system simulations in the end.
