摘要
采用ARM架构的嵌入式CPU,完成了多媒体浏览器的设计与实现。首先在Intel XscalePXA270上搭建一个完整的嵌入式Linux操作系统平台,包括bootloader、内核以及文件系统的裁减与移植,并且开发了相关的驱动程序,如蓝牙驱动、触摸屏驱动、矩阵键盘驱动、SD/MMC卡的驱动以及LCD显示屏的驱动等,用于完成系统基本的输入输出功能;然后在系统上移植了QT4用于设计应用程序和友好的GUI界面,并在此基础上开发/移植了图象浏览、视频播放、日历时间、文本浏览等功能软件;最后设计了友好的GUI界面,将这些软件有机的组织在一起,形成了完整的多媒体浏览器系统。
Under the architecture of ARM embedded CPU, a multimedia browser system was designed and implemented. Based on the embedded platform of Intel Xscale PXA 270, firstly, a complete embedded Linux OS platfoim was built up for controlling the system, including bootloader for system,kernel and filesystem, and the drivers such as Bluetooth, touch screen, keyboard, sd/mmc card and LCD were developed; Then QT4 was ported to design user GUI and applications; the applications for picture, video, time, file were furthermore implemented. The client software in B/S architecture was designed for functional validation.
