frame buffer writer and reader only mode

Hi dear,
I'm triyng to realize a system in which one frame buffer (write mode), stores data in one external memory. Then by the NIOS I would like to buffer this data in another area of memory and then by a second frame buffer (read mode) I would like to send this frame to the CVO.
The pipe should be something like this TPG - w_frame_buffer - NIOS - r_frame_buffer - cvo.
Does some example design exist like this?

I'm at the moment reading the writer frame buffer from nios. But I'm not able to generate a correct stream video by the reader frame buffer.


Thanks

    Hi,


    As I understand it, you have some inquiries related to the frame buffer which has NIOs as intermediate. Sorry as I am not aware of any specific example like this. Based on my understanding, generally the setup that I have come across does not have NIOs to transfer the data from frame buffer. For example, one setup would looks like TPG -> de-interlacer -> frame buffer -> CVO.


    Please let me know if there is any concern. Thank you.
