摘　　要：随着现代信息系统任务量的日益庞大,系统对通信带宽、响应速度和可靠性的要求越来越高,通常采用高速高可靠的串行RapidIO总线来完成系统中诸如信号处理模块、数据处理模块、网络交换模块上所有节点之间的互联入网、数据传输,其中节点入网是网络通信的首要和重要条件,某个节点入网失败将导致该节点无法进行后续通信,所以节点入网成功率尤为重要。为提高节点入网成功率,文中介绍了一种兼容国产和进口串行RapidIO总线交换芯片的通信系统,该系统在节点不重新启动的情况下可以高效并可靠地纠错串行RapidIO总线状态,使得各节点可以100%成功入网,提高系统的实时性、稳定性和可靠性。An increasingly large amount with the task of modern information system,the system of communication bandwidth,response speed and reliability of the demand is higher and higher,so usually adopt high⁃speed serial RapidIO bus with high reliability to complete in the system,such as signal processing module,data processing module and network exchange module interconnection between all nodes on the net,data transmission,node access is the primary and important condition of network communication.In order to improve the success rate of node access to the network,a communication system compatible with domestic and imported serial RapidIO bus switching chip is introduced in this paper,which can correct the serial RapidIO bus state efficiently and reliably without restarting the node,reaching 100%success of each node access to the network,and improving the real⁃time stability and reliability of the system.
