摘　　要：根据实际应用中嵌入式系统常需要具备USB主机功能而大多数微处理芯片没有集成这一功能的实际情况,提出了一套基于S3C44B0X和SL811HST的系统解决方案。本系统以ARM7核心板加USB扩展板为硬件实现方法;在ucLinux系统下实现USB驱动程序的编写和加载。该系统成本低廉,运行稳定,适合应用于手持式设备上及野外工作场合。According to the fact that embedded system needs have the function of USB host in practical application but most micro- processing chip usually has not, a scheme has been put forward to the system based on S3C44BOX and SLSllHST.This system use core board of ARM7 and expand board of USB as the way of hardware＇s method ;write USB driver and load it under ucLinux system. This system has the advantages of low cost and stable operation. It can be used in handheld devices and fieldwork occasions.
