扩展二维网格片上互连性能分析

为了解决Mesh网格在某些情况下不能满足片上网络互连需要的问题,将Mesh网格扩展到三角形和六边形网格,在分析不同结构静态特性并揭示不同结构的内在联系的基础上,基于全局均匀随机通信模型,通过改变网络规模和变换通信强度,分析了不同结构网络的动态特性,最后用链接数表示通信成本,使用该文提出的网络单位成本延迟负载能力这一技术指标,对不同互连结构的综合性能进行了对比,并指出了它们分别适用的场合。实验结果表明,在大规模超大规模片上多处理器中直接单独使用任何形式的二维网格互连均不能取得很好的性能。

Interconnection analysis of extended 2-D grid networks-on-chip

Mesh grid cannot match the need for the net-works-on-chip interconnection in some cases. 2-D mesh grid was extended to 2-D triangle and hexagon grids to reveal the topologic relationship. Load per cost-delay product was proposed by the authors which is a new evaluation to the all-sided performance of interconnection networks-on-chip. After analyzing the networks characteristics of different structures based on the stochastic model by changing the scales and loads,load per cost-delay product was used to anal...
