Read and Write from FIFO AL422b in Vivado

Hi,

I would like to drive an image sensor (Ov7670 + Al422b) with a Cora z7 and for that I have to read in the image data in the FIFO (Al422b) and read out.
How can I do that in Vivado?

Thanks!

Hi mbiendadannick@yahoo.fr 

You could start by explaining how this frame buffer is supposed to interface with anything... 

what is the clock frequency. How is the data sent? Parallel or serial? Where is the clock coming from. Is there a specific standard used here. 

From the IO side. what signalling is used. 

Share a timing diagram..

Do that first then we can give you more advise. 

I am going to move this to the Video Board.
