中文摘要:随着处理器和机载嵌入式实时分区操作系统等相关技术的不断升级换代,IMA系统功能的集成度也越来越高,高集成度增加了系统资源分配的难度,需要通过对系统资源状态进行实时监控和分析进而不断优化系统配置。首先对IMA系统的分区特性进行了深入研究,基于探针插桩监控数据采集技术,提出了一种系统行为和时间资源状态监控的策略。研究了数据监控采集系统的软件架构,在此基础上设计和实现了系统行为监视器和时间资源监视器,并在某民机重点预研课题中进行了应用验证。结果表明,能够有效帮助应用开发者和系统综合者直观分析系统时间性能瓶颈,优化资源配置方案,实现计算资源的负载均衡。对IMA系统资源状态监控及资源配置优化具有一定的指导意义和实用价值。
英文摘要:Integrated modular avionics(IMA) system is widely utilized in the field of civil aircraft airborne avionics system, which is the trend in the aviation field. With the continuous innovation of the technology, the integration degree of IMA system functions is getting higher and higher. It can not only lead to more difficulties of resource allocation, but also bring challenges to the security of the system. This paper does the detailed research on the partition characteristics of IMA system and proposes a systematic behaviour and a strategy of time resource monitoring on the basis of data acquisition technology of probe instrumentation monitoring. In addition, the system architecture of data monitoring and acquisition technology was presented in this paper, which system resource monitor and time resource monitor were designed on the basis. When it comes to the implementation of resource status monitoring, the function and orientation of target and host terminal monitoring and control softwarewere clarified. In the meanwhile, the solution how to view monitoring data by software is also given in this paper. This paper has a certain guiding significance and practical value for IMA system resource status monitoring and resource allocation optimization.
