对于低成本的嵌入式平台，内存和芯片的性能都是有限的。为了减少多媒体播放列表对资源的占用，文中基于FAT文件系统的特点，提出了一种新的嵌入式多媒体播放列表的解决方案。该方案创新主要体现在两个方面：用文件起始簇号代替文件路径；不缓存文件信息，实时获取文件信息。该方案和传统方案相比具有内存使用大幅减少，响应速度快的特点。在实际的产品中实现了该播放列表方案，测试结果显示播放列表资源占用大幅降低，运行性能良好，能有效地降低产品的成本。

For low cost embedded platform,the performance of memory and chip is finite. In order to reduce the resource occupation of playlist,based on the characteristics of FAT file system,present a new playlist solution for embedded system. This solution includes two innovations:One is that file beginning cluster replaces the file path;Second is to get the file information in real-time,not caching the file information. Compared with traditional solution,this solution reduces the memory occupation and has fast response speed. This new solu-tion has been implemented in the real product. The testing result shows that the new solution has small resource occupied and good per-formance,which can reduce the cost effectively.
