摘　　要：随着信息技术的发展,DSP技术应用越来越广泛。其运算结果往往需要送到计算机中显示或存储。传统的通讯技术一般采用串口通讯。随着数据通讯量的增加,串口通讯越来越成为整个系统工作的瓶颈。本文所介绍的USB通讯技术通讯速率可达8Mbps,能较好地解决这一通讯瓶颈问题。With the development of information technology, the application of DSP technology is used more and more widely. The result usually need send to computer for displaying or saving. The customer communication technology usually use serial communication. With the increasing of data traffic, serial communication become the choke point of system working. The communication speed of the USB communication technology this paper puts forward can achieve 8 Mbps, and it can well resolve the problem.
