Write portion of frame buffer

Hi i would like, when i receive a new frame, to select the central part of it (clip) and store it in memory. The position where i save this piece of frame should depend on the frame number like this...

Thanks for your reply!

i think i need an interface between the video streaming(Avalon ST interface) coming from the clipper, and the memory controller (Avalon MM interface).

es.

Frame 1 --> Clipper --> write this data at location 1 in memory --> Frame Reader

Maybe using a dma or i need a custom component?
