基于天脉1操作系统的HKSP6101处理器看门狗驱动的设计与实现

Design and implementation of HKSP6101 processor watchdog driver based on ACoreOSl.X operating system

看门狗机制是防止计算机控制系统出现不可逆转的故障的一个主要措施,合理使用此机制可以较大程度上提高系统运行的可靠性。针对目前天脉一嵌入式操作系统缺乏看门狗驱动具体设计与实现的问题,分析了基于HKSP6101国产处理器的控制接口模块看门狗驱动的框架结构及驱动程序设计流程,主要包括设备访问、寄存器组的读写、中断处理机制等内容。经过多轮测试和大量实际应用,证实该文设计的看门狗驱动程序能够对HKSP6101处理器芯片的系统状态进行稳定监控。

The watchdog mechanism is one of the main measures for anti-interference design of computer control system.The rational use of this mechanism can improve the reliability of the system to a large extent.In view of the lack of specific design and implementation of the watchdog driver in ACoreOSLX embedded operating system,the framework structure and driver design flow of the control interface module watchdog driver based on HKSP6101 domestic processor are analyzed,including device access,register group read and write,interrupt processing mechanism and so on.After many rounds of testing and a lot of practical applications,it is proved that the watchdog driver designed in this paper can stably monitor the system state of HKSP6101 processor chip.
