fpga hdmi Image processing based on Zybo Z7 HDMI Input/Output Demo

[Jianchao]

Hi there,

I got a problem that I want to implement a image process algorithm on zybo z7 board, and I used the provided HDMI input/ouput demo as RX/TX interface, but the demo project is not editable.

The HDMI signal will be decoded to 24-bit RGB signal after the div2rgb module, and I want to add a module to do some adjustments on the RGB signal, and then connect the processed RGB signal to the rgb2dvi module.

So, is there any suggested solution to add customize design into the demo project?

Thanks in advace !

Hello @Jianchao,
What exactly do you mean by not editable?
For the image processing part, it might be easier for you to create a custom IP (via HDL or HLS) that uses an AXI4-Stream interface and connect it to the video_in port instead of vid_io_out. Your algorithm may introduce latency and by processing data from vid_io_out, your data (vid_data) may no longer correspond to your synchronization signals (vid_hblank and vid_hsync).
