DM355 IPIPE resizing

Sebastian Kruber

Hi,

In my application I store 768x480p60 frames from CCDC to SDRAM. My TFT can only display 720x480 resolution, so I am using IPIPE to rescale the frame.

Unfortunaly sometimes some strange artefacts appear on the resized frame.

It looks like the frame is shifted by a couple of byte at certain line.

Does anyone know how this can be possible and how I can make the arctifact vanish?

Best regards,

Sebastian

    Hi,

    I am still working on this one. The frame ripping appears less now, as I transfered a lot of my interrupt handling stuff to SRAM, but its still there!

    What exactly is happening here?

    I know that if I have too much load on my SDRAM, the VPBE does get its data too late sometimes and wrong pixel appear on my screen. But this kind of ripping the frame appart is realy strange to me.
