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。
In order to solve the problem that Mesh mesh can not meet the needs of on-chip interconnection in some cases, Mesh mesh is extended to triangles and hexagons. Based on the analysis of the static characteristics of different structures and revealing the internal relations of different structures , Based on the globally uniform stochastic communication model, the dynamic characteristics of different structural networks are analyzed by changing the network size and changing the communication strength. Finally, the link cost is used to represent the communication cost. Using the technical index of the network unit cost delay load capacity proposed in this paper, The overall performance of different interconnect structures are compared and their respective applications are pointed out. The experimental results show that good performance can not be achieved by directly using any form of two-dimensional grid interconnection directly on a large-scale, large-scale on-chip multiprocessor.
