| Abstract: | 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. |
