Design on High Speed Data Channel in Pipelining Multiple SIMD Cluster Network Architecture

本文对基于层次总线的ＰＭ－ＳＩＭＤ机群网中的数据传输拓扑进行了研究。改进了传统的数据传输通道设计方式，根据缓冲资源从传输资源中分离的原则，建立了两种虚拟通道模型。理论分析和仿真结果均表明，虚拟通道结构能够改善通道共享性、提高通道吞吐率。

In this paper,the data transmission topo in pipelining multiple SIMD(PM SIMD) cluster network is studied based on hierarchical bus architcture. The conventional model of data transmission between clusters is modified and two models of virtual channel are established, on the basis of the principle of separating buffer resource from transmission resource. After theoretical analysis and computer simulation, it is shown that the architectures of the virtual channel improve the share of the channels between the clusters and increase the throughput of the channels.
