| 摘 要： | 研究了利用嵌入式软件在便携设备中融入多种通信应用。基于Linux实时操作系统,采用了C/S模式、UDP协议及多线程技术等,综合运用JAVA、C以及汇编语言,开发了一种运行于ARM9嵌入式处理器的实时语音全双工通信和数据传输系统。在系统服务器设计了MySQL数据库作为客户端之间传输控制信息的转发点,进而完成交互通信功能。测试结果表明,该系统在局域网内通信可靠,实现了ARM-ARM的实时语音通话和文件传输。

| Abstract: | Integrating multiple applications of communication into portable device by using embedded software is proposed. Based on Linux real-timeoperating system (RTOS) and through adopting C/S mode,UDP protocol and multi-thread technology, utilizing Java,C and assembly language, a real-timesystem of full-duplex voice communication and data transmission over ARM9 embedded processor is developed. As the transfer point of transmittingcontrol information among clients, the system server in which MySQL database is desig... |
