摘　　要：为了满足机载嵌入式系统自主可控要求,针对全国产化软硬件的差异,提出了一种基于RapidIO交换网络的软件通信方法,解决了RapidIO网络管理与通信中间件的国产化适配问题,构建了与进口软硬件一致的应用软件运行环境,最大程度地支持应用软件的可移植、可重用。测试验证与工程应用表明,所提方法支持应用软件从进口芯片到国产化替代的平滑迁移,基于RapidIO总线的通信服务与进口件功能一致,能够有效提升国产化系统的集成效率。In order to meet the autonomous and controllable requirements of airborne embedded system,a software communication method based on RapidIO switching network is proposed to solve the problems of adapting RapidIO network management and communication middleware to domestic chip,so as to build an application software operating environment consistent with imported chip and software.It supports the portability and reuse of application software.The test verification and engineering application show that the proposed method supports the smooth migration of application software from imported chip to domestic substitute.The communication service based on RapidIO bus has the same function as the imported chip,which can effectively improve the integration efficiency of the domestic system.
