摘要
RapidIO是一种针对高性能嵌入式系统芯片级、板级互联而设计的总线技术,广泛应用于航空电子系统。为了实时地管理RapidIO网络,提出了基于预置带宽与硬件事件的管理方法,设计并实现了分布式系统网络管理软件,实现不同规模网络的动态管理与容错处理。测试验证与工程应用表明,所提方法解决了大规模网络的动态管理问题,能够满足机载嵌入式系统强实时、高性能、高可靠的应用需求。
RapidIO is a bus technology designed for high-performance embedded system chip-level and board-level interconnection,which is widely used in avionics systems.In order to manage the RapidIO network in real time,a management method based on preset bandwidth and hardware events is proposed,and a distributed system network management software is designed and implemented.Thus,the dynamic management and fault-tolerant processing of networks of different scales can be realized.The test verification and engineering application show that the dynamic management problem of large-scale network is solved,and it can meet the application requirements of strong real-time,high performance and high reliability of airborne embedded systems.
