Honored ContributorWrite 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...

Honored ContributorWhat kind of frames? Ehternet or whatever?
DVI Video Frames Where do frames come from? From a Camera What IP or module are you using? Altera VIP , DDR2 Memory Controller How are you supposed to write into memory? Now i write all the frames into a frame buffer i would in future: Get Video Frame 1 --> Take a small portion of it--> write in position 1 Get Video Frame 2 --> Take a small portion of it --> write in position 2 and so on... Then i would read a video frame composed of those pieces: | 1 | 2 | 3 | 4 | Every time i get for example frame 1, i refresh the portion of video in position 1
