嵌入式设备驱动程序独立加载技术

针对嵌入式软件开发的特点,运用独立加载技术实现对嵌入式系统驱动程序代码的独立加载和升级。设备驱动程序独立加载技术打破了多个嵌入式软件模块合编成单个目标文件的传统模式,将各个软件模块进行独立和分离,通过硬件自动扫描引擎自动检测硬件设备,程序加载器构建设备链表和驱动程序链表,并根据配置信息分别加载相应的驱动程序和应用程序,实现多个嵌入式设备驱动程序的独立加载。嵌入式设备驱动程序独立加载技术的研究和应用为各系统组件和应用模块的独立开发以及软件模块动态扩展和独立升级提供了捷径,降低了嵌入式软件协作的人力和时间成本。

The Independent Loading Technology for Embedded Device Drivers

The embedded software module independent loading technology implements the independent loading respectively of drivers. Not the same as the traditional mode which compile some embedded software modules into one object file, the embedded software module independent loading technology achieved through separating the software module independently, detecting hardware equipments automatically by hardware auto scan engine, constructing the equipment list and driver list by programme loader and loading corresponding drivers and applications respectively according to configuration information. The application and research of the embedded software module independent loading technology provide a shortcut for the independent development of system groupware and application modules, dynamical expanding and independent updating of software module. It also reduces the cost of person and time in software cooperation.
