    To stream video data from fpga to fx3

      To stream video data from fpga to fx3 what changes should be made in image sensor interface an75779 using it as a reference.

          Hello,

           

          - When FPGA is used between image sensor and the FX3, the UVC class specific headers can be added in the FPGA and FX3 acts as a slave FIFO interface passing the data over to the PC host. In this case, refer to the AN65974 application note for data transfer related part of the firmware. The descriptor and the request handling complying to UVC class still remains the same as in AN75779.

            hello sir , i want to stream data from fpga in yuy2 format to host pc , will the above explanation be enough for this or i have to create another interface for that.

              Hello,

               

              The YUY2 data from the image sensor will be padded up with the UVC headers in the FPGA. The data sent out by the FPGA will be treated as a raw data by the FX3 which passes it onto the host. There is no need to create a separate interface for this. The UVC based descriptor information is sufficient. The UVC class specific requests should be handled and communicated to the FPGA which should in turn pass it onto the image sensor (if necessary).
