| 摘 要： | 提出一种使用UML(统一建模语言)对Linux设备驱动进行分析的方法，借助UML对设备驱动程序模型进行建模并分析，从而明晰设备驱动组件之间的依赖关系，明确设备驱动开发的重点。在此基础上对SDWiFi设备驱动程序模型进行了研究，设计处理器与Wi-Fi芯片之间的SDIO通信接口，移植SDWiFi设备驱动程序。最后使用无线工具包对SDWiFi无线网卡设备进行了配置和测试，测试结果表明SDWiFi无线网卡设备工作正常，通过使用UML对设备驱动程序模型进行建模和分析，可以提高设备驱动程序开发效率。

| Abstract: | A method to model and analyze the device drivers in embedded Linux system using UML was proposed.By using UML modeling method,the dependencies among the device driver components and the focus of the device driver development are clarified.On this basis,the SDWiFi device driver model was studied,the SDIO communication interface between the host and Wi-Fi chips was designed and the SDWiFi device driver was transplanted.At last,the SDWiFi wireless LAN equipment was configured and tested using wireless tools.The test results show that the SDWiFi wireless LAN equipment works properly.The efficiency of the device driver development is improved by modeling and analyzing the device drivers using UML. |
