摘　　要：针对USB主机嵌入式的需求,研究和设计了基于SL811的嵌入式USB主机系统。通过USB主从控制芯片SL811,把一个基于ARM7的嵌入式系统做成一个带USB接口的主机。用C语言编写USB主机驱动程序,通过交叉编译器arm-linux-gcc和arm-elf-tools分别对U-Boot和uCLinux进行移植及编译,从而实现嵌入式USB主机对U盘的读写操作。An embedded USB host system based on the SL811 is researched and designed.The system can make an embedded system of the ARM7 into a host with USB interface by an USB host/slave-controlling chip of SL811.The drive program of the USB is written in C language.Then the U-Boot and uCLinux are grafted and compiled by arm-linux-gcc and arm-elf-tools cross-compiler respectively. The operation of reading and writing U dish of embedded USB host are achieved.
