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 the needs of more and more people to access information services anytime, anywhere, a high-performance PDA is proposed. It is based on TI’s open multimedia application platform (OMAP) design, embedded Linux as the operating system, using ported Q top ia as the windowing software system, multimedia protocol stack optimized for OMAP as the middleware and QT / E as a tool for developing application-specific software. In addition to its regular functions, the PDA supports multimedia applications such as camera and video playback in a mobile environment and provides an upgrade interface for Bluetooth, GPS, 3G and SDIO modules to support applications such as wireless Internet.
