摘　　要：针对现有大规模的综合化电子信息系统中RapidIO节点管理实时性不强、CPU资源占用多的问题,提出了一种基于port write事件触发的RapidIO节点动态管理方法。该方法利用RapidIO交换芯片的port write包上报退网或者入网的节点信息,通过该信息动态管理RapidIO网络中的所有节点。工程应用实测结果表明,该方法实时性高,CPU资源占用少。A dynamic management method for RapidIO nodes based on port-write event triggering is proposed to address the issues of low real-time management and CPU resource occupancy in large-scale integrated electronic information systems.This method utilizes the port-write packet of the RapidIO switching chip to report the information of nodes that have retired or entered the network,and dynamically manages all nodes in the RapidIO network through this information.The actual engineering application results show that this method has high real-time performance and low CPU resource consumption.
