A civil onboard module watchdog design method based on an X86 architecture

The invention belongs to the technical field of computer communication. An X86 architecture processor platform and the related content of BIOS coding and logic design are designed, a new watchdog using method is invented for the application of the X86 architecture platform in an airborne embedded environment, the BIOS is coded through the BIOS, and the GPIO type of the processor is configured to be an SCI interrupt pin; and according to the airborne embedded environment requirement, the watchdog signal is logically coded, the watchdog signal is enabled, and an interrupt signal is triggered. According to the invention, the flexibility and the configurability of watchdog signal application are realized, and a method is provided for applying an X86 platform to an airborne embedded environment. 本发明属于计算机通信技术领域，设计X86架构处理器平台，BIOS编码和逻辑设计的相关内容，针对X86架构平台在机载嵌入式环境中的应用，发明了种新的看门狗使用方法，通过BIOS对BIOS进行编码，处理器GPIO类型配置成为SCI中断管脚；并根据机载嵌入式环境需要，在逻辑里对看门狗信号进行编码处理，对看门狗信号进行使能，触发中断信号。本发明解决了看门狗信号应用的灵活性和可配置型，为X86平台应用于机载嵌入式环境提供了方法。
