External USB introduce a non-destructive image acquisition card design and implementation of the program, and it is used for special occasions image processing and its related fields. For image transmission characteristics, combined with FPGA/CPLD and USB technology, hardware implementation block diagram is given, at the same time gives the FPGA/CPLD Internal Timing Control charts and USB program flowchart, diagram, and some combination of source code, specifically about the topic Difficulties encountered and the corresponding solutions.
