摘　　要：为了满足越来越多的人们随时随地享用信息服务的需求,提出了一种高性能的PDA。它基于T I开放式多媒体应用平台(OMAP)设计,采用嵌入式L inux作为操作系统,采用移植的Q top ia作为窗口软件系统,采用针对OMAP优化了的多媒体协议栈等作为中间件,并采用QT/E作为开发特定应用软件的工具。该PDA除具有常规的功能外,还支持移动环境下的摄像、视频播放等多媒体应用,并提供蓝牙、GPS、3G、SD IO模块的升级接口,以支持无线互联网络等应用。In order to meet more and more people＇s needs of information service anywhere and anytime, a PDA is proposed in this paper. It is designed on the basis of TI＇s open multimedia application platform（OMAP）, adopting embedded Linux as the operation system and migrating Qtopia as the window＇s software system, adopting optimized multimedia protocol stacks for OMAP as the middleware, and adopting QT/E as the tool developing specific application software. Besides the usual functions, it can be used as a digital camera, multimedia player and so on. The PDA also provides interfaces of Bluetooth,GPS,3G,SDIO for wireless network applications and other. The design is feasible after thoroughly argumentation, and takes advantage of dual- core proeessor＇s excellent performance. It has features of multifunetion, low power consumption, easy expansion and convenient operation.
