摘　　要：介绍了一种基于硬盘MP3播放器的USB海量存储类主机的设计与实现方案。该方案利用SL811HS芯片在Sig-matel公司的STMP3560DSP架构下实现了USB各层协议,并在此基础之上构建了支持fat16与fat32文件系统的usbmassstorage主机。实验与测试结果表明:该方案具有良好的稳定性和兼容性,能够支持多款闪存盘与数码相机。A scheme for the design and implementation of USB Mass Storage host based on hard disk MP3 player is mainly described. Under the architecture of STMP3560 DSP manufactured by Sigmatel, this scheme implements each layer of the USB protocols with SL811HS chip. On this foundation, the USB host of mass storeage is constructed which supports two file systems（FAT16 and FAT32）. The result of experiment shows that this design can be used to transfer data stably, supporting a number of flash disks and digital cameras.
