摘　　要：本文对综合显示控制系统基于FC故障注入的容错设计的健壮性进行分析,使用故障注入设备通过FC总线向综合显示控制系统注入十种故障模式,统计视频处理单元的在线状态以及屏幕切换功能的完整性以进行健壮性分析,进而挖掘系统FC总线设计的薄弱环节,最终给出提高系统设计可靠性水平的建议。The robustness of the fault-tolerant design of the integrated display control system is analyzed based on FC fault injection.By injecting 10 fault modes into FC,the integrity of the screen switching function with good online sta-tus of VPU is counted to evaluate the robustness.Furthermore,the weak links of FC bus design are explored to improve the system design and enhance the robustness.
