摘　　要：介绍了1种基于ARM11嵌入式平台和嵌入式Linux内核,界面美观、操作便捷的高保真无损音乐播放器的设计。它支持WAV、FLAC和APE3种无损压缩格式音乐;还可通过触摸屏实现浏览音乐目录,控制音乐的播放、暂停和调节播放进度等控制功能;它支持外接移动硬盘、SD卡和优盘等大容量存储设备。在开发平台上已实现采样位数16或24,采样率上限48kHz的WAV、FLAC和APE高保真音乐播放。The design of High-Fidelity lossless music player which is based on ARM 11 embedded platform with embedded Linux kernel is presented. It supports 3 kinds of lossless compression format including WAV, FLAC and APE. Functions such as browsing music directories, music playback or pause and adjusting playback progress have been realized by tapping the touch screen. Extemal mass storage devices such as mobile hard disk, SD card and USB flash disk are also supported. High-Fidelity lossless music （WAV, FLAC and APE）playback has already been realized on the development platform with music sampling bits 16 or 24 and sampling rate lower than 48 kHz.
