摘　　要：详细介绍了一种基于ARM7内核处理器开发的USB主机系统。实现读取一个U盘的数据并写入另一个U盘的功能。系统硬件方案设计具有成本低、功耗小、速度快等特点。在软件上,系统完成了USB主机控制器驱动程序、核心驱动程序以及用户软件的设计,可很好地完成设备的枚举、配置等功能;系统支持Mass Storage类协议,并建立了精简的FAT文件系统,可以完成U盘上文件的读取,使USB应用脱离个人电脑具有普遍意义。论文就USB主机系统作了总结和分析,并对嵌入式USB主机的发展前景作了展望。This paper introduces a based on the ARM7 core processor developed USB host system. Implementation of a U disk data read and writes another U disk function. System hardware design has the advantages of low cost, small power consumption, speed etc.. In the software, the system completed the USB host controller driver, the core driver and user software design, well completion equipment enumeration, configuration and other functions; the system supports Mass Storage protocol, and the establishment of a FAT simplified file system, can complete the U disk file read, so that the application of USB detachment the personal computer has universal significance. Research of USB system are summarized, and the embedded USB host development prospects
