基于多层树形结构的PCIE总线配置技术研究

摘要

不同于以往的PCIE总线直接挂载设备的配置方式,研究了基于多层树形结构的PCIE总线配置技术,通过两层拓扑结构详细阐述了树形PCIE总线的配置过程,并通过对设备的扫描和访问测试实验证实了配置技术的有效性.%Different from the usual technology of mounting the device directly to the PCIE bus,this article introduces a configuration technology which is based on multilevel tree structure.The detailed process of configuration is showed by configuring a two-level tree of PCIE bus,the experimental result performed on scanning and testing device demonstrated the effectiveness of proposed technology.
