USB to AXI4

[freetoair]

Hi WangXuan95,

This is not a bug but a suggestion to improve your excellent project. First of all, I would like to say that any of your USB implementations work great on Sipeed Tang Nano 20k development boards. I need to create an interface with a single design for DATV (digital amateur television) that connects to the outside world via two AXI4 interfaces. One is AXI4lite and the other is AXI4 stream. Namely, AXI4lite is needed for configuring registers and debugging, and AXI4 stream is used for transferring transport stream video data. I would like to hear your opinion on whether I need a composite USB interface for this or can it be achieved with two endpoints. I tried to do something with AXI4 fifo but without any major success. Otherwise, the transfer speed of the video transport stream is quite low, at most about 1 Mbit/s.
