摘要
针对现有技术对于处理器的监控仅支持在处理器运行之后的自检,而在处理器启动过程中无法针对启动过程中的故障进行定位的问题,本文设计了一种基于MCU的X86系统监控方法,MCU不依赖于X86处理器,与之并行运行,实时对X86系统进行监控,并且MCU运行之后不需要任何人工干预,可对X86运行过程中出现的问题进行声光报警,并指示出出错位置,易于工程维护。
To the question which current technology only support processor monitoring in POST but don’t support error positioning during processor booting,a new approach of monitoring X86 system based on MCU is designed in this paper. Keep parallel operation with CPU but not relying on it,MCU is able to monitor X86 system in real time and totally unmanned after booting. The MCU also provides sound-light alarm and error positioning for easy to maintain.
