信号处理系统中RapidIO网络配置管理方法研究

Research on RapidIO Network Configuration Management Method in Signal Processing System

随着航电系统一体化平台的发展,航电系统中的RapidIO多采用串行I/O和基于交换的拓扑结构。设计了一种基于RapidIO交换网络的信号处理系统,采用PowerPC8548E作为I^(2)C的主设备完成RapidIO交换设备的上电初始化,依据系统的RapidIO网络配置,利用RapidIO维护操作实现对网络上设备枚举和路由配置等功能。这种配置方法灵活,性能优良,不仅能满足系统的应用需求,同时使系统在可重构性、可扩展性、可维护性等性能指标上均获得了显著的改善。

With the development of the integrated platform of avionics system,RapidIO in avionics system mostly adopts serial I/O and switching-based topology.This paper designs a signal processing system based on RapidIO switching network,using PowerPC8548E as the host of I^(2)C to complete the power-on initialization of RapidIO switching equipment,according to the RapidIO network configuration of the system,the use of RapidIO maintenance operation to achieve the functions of enumeration and routing configuration of devices on the network,this configuration method is flexible and has excellent performance,which can not only meet the application requirements of the system,but also make the system reconfigurable,expandable,performance indicators such as maintainability have been significantly improved.
