【摘要】 当前航空电子系统是一个高度综合化、模块化的系统,作为其基础平台的核心处理计算机系统是一个综合数据处理、信号处理和图像处理的实时分布式计算机系统,可靠性要求很高,必须采用容错技术。文章在介绍实时分布式计算机系统硬件和软件结构的基础上,重点对容错技术进行了研究,提出了分层的容错管理策略,并通过具体实例说明了故障监控、故障处理和系统重构的方法。更多还原

【Abstract】 A future avionics will be a highly integrated, modularized system, running on its platform called Integrated Core Processor System (ICPS), which is real time distributed computing system integrated with data processing, signal processing and graphic processing. In order to meet the reliability requirement, fault tolerance techniques are generally used in designing the ICPS. This paper describes the hardware and software structure of the IPCS system, and presents the fault-tolerance management strategies and an example of the process of the fault monitoring, fault processing and system reconfiguring.更多还原
