摘　　要：介绍了基于TMS320C6713型DSP控制的通用串行总线(Universal Serial Bus,简称USB)嵌入式主控制器SL811HS的设计方案;给出硬件设计电路和软件设计流程。由于USB协议的复杂性,因此重点介绍了驱动程序设计在数据传输时对各种状态的判断和处理,尤其是Bulk-Only协议中CBW包的传输。实验证明,该方案可实际用于野外数据采集系统。It is a very important application that ultra-large capacity data collection-storage system controlled by DSP chip.This article mainly describes the design of host controller chip SL811HS controlled by DEC6713,the connection of hardware design, software design programmes and the specific process.Because of the complexity of USB protocol,it is focused on the design of the drivers,judgement and handling of data transmission in various states,especially the transmission of CBW package in BULK-Only protocol.Finally,the experimental results proved that the design can be used in field data collection system.
