介绍了一种微处理器系统运行参数的存储方法,并且在多款微处理器系统下进行参数存储使用。本方法借助系统已有的数据存储芯片,硬件上节省了器件成本;软件复用存储芯片读写代码,节省代码,可以快捷地查找当前在用参数和历史的备份参数。通过在多款微处理器系统上的使用效果来看,该方法具有运行参数存储稳定、开机启动时参数加载可靠等特点,未出现因运行参数读取失败导致系统死机的情况。

In the paper,a method of storing the operating parameters of a microprocessor system is introduced,and stores the parameters in many types of microprocessor systems.With the help of the existing data storage chip of the system,the hardware saves the cost of the device,and the software reuses the read and write code of the storage chip to save the amount of code,which can quickly find the current parameters in use and the historical backup parameters.According to the use effect on several microprocessor systems,it has the characteristics of stable storage of operating parameters and reliable parameter loading when starting up,and there is no case of system crash due to failure of reading operating parameters.
