基于ARM的嵌入式藏文电子阅读器的设计与实现

Design and implementation of embedded Tibetan e-reader based on ARM

为推动民族文字信息化的发展,利用ARM9嵌入式开发平台,通过扩展SDRAM模块、USB模块、以太网控制模块和触摸屏模块,结合QT技术,设计了一款嵌入式藏文电子阅读器。论文给出了系统的总体架构,硬件实现原理框图及软件设计流程。实验结果表明,该系统成功实现了全藏化的阅读器应用程序界面,并可以支持TXT、HTML、PDF、DOC格式的藏文电子书的正常显示、阅读和编辑,同时可进行BMP、JPEG、PNG等格式的图片文件的浏览,系统运行稳定、安全可靠,使用便携灵活。

To promote the development of national characters＇ informatization, an embedded Tibetan E-reader which combined with QT technology is designed, It is based on ARM9 embedded development platform and extend SDRAM module,USB module, Ethernet control module and touch screen module. The architecture of the system, hardware principle diagram and software design process are described. In the test, the system successfully achieved graphic user interface of tibetan reader application program, and can display, read and edit Tibetan e Book such as TXT, HTML, PDF, DOC format, at same time images including BMP, JPEG, PNG can be browsed, the system is proved to be stable, reliable, portable and flexible.
