摘要
DSP的高速运算性能使它在视频处理上具有很大优势,但视频传输数据量非常大,需要高速的接口实现与PC机的连接,为此设计了基于高速DSP视频处理系统的USB传输接口电路.介绍了系统的整体框架,详细论述了构建和实现USB接口电路的方法,给出了系统的软件设计思路.实验表明,设计方案可行,通过USB传输接口可实时实现压缩视频信息的传输.
DSP has advantage of video process because of its high operational capability, but video data are very large, high speed interface is needed, so an USB transfer interface based on high speed DSP has been designed. The whole frame of the system is introduced, the method of construct and implement the interface circuit of USB is discussed, and the software design idea is given. Experiment results show that the design scheme is feasible, and compressed video data can be transferred in real-time through the USB transfer interface.
