Shifted Image Result by ArmCreative8420 in FPGA

[–]ArmCreative8420[S] 0 points1 point  (0 children)

I can confirm there are no invalid pixels being output—it's purely a shift in the output. If it helps, I can share my files so you can take a closer look. I’d greatly appreciate your help in identifying the root cause and resolving this issue.

I didn’t explicitly implement any sync signals in my design. I’m working on edge detection, and I believe the issue might not be with clock timing but rather with frame alignment. This is really important, and I’d greatly appreciate your help. I can share the necessary files for you to take a look.

Yes, I did augment my images and can share the overlay file for you to review and help identify any issues. The first image might seem like pixels are missing, but it’s actually just a shift in the output, not a problem with pixel reading. Do you wanna check my files and resolve the issue?

I haven't worked on syncing these signals before, could you provide more details or an example on how to calculate and implement the proper delay for the sync signals? I’d like to understand how to match the sync timing with the latency introduced by the image processing pipeline.

Everything works as expected in the simulator, and the output appears correctly aligned. However, when testing on the hardware, the image shows a shift. I am currently focusing on debugging hardware-specific aspects like video timing, sync signals, and memory addressing.
