| 摘 要： | 设计开发的基于ARM处理器可同时实现网络收音机和MP3播放器功能的嵌入式平台。利用S3C2440芯片的特点,以ARM处理器及其外围模块为硬件平台,采用嵌入式Linux作为操作系统,用MPLAYER播放软件,实现了MP3播放器及网络收音机的全部功能。在软件方面,为了更好支持对音频数据的播放,在Mplayer源码中添加Madlib库和Live协议包。测试结果表明,系统性能良好,具有较好的市场应用前景。

| Abstract: | An embedded platform has been designed based on ARM processor,which realizes the functions of Ethernet radio and MP3 player.Based on the characteristics of S3C2440,the system is designed by using ARM processor and some outer module as hardware platform,using embedded Linux as operation system,and using Mplayer as Ethernet broadcast software.In order to support a smooth process of data,the Madlib and live protocols has been added to the source software,Mplayer.The test results indicate that the performance o... |
