PCIe and Scaler II IPs

Hi, I’m working on a project that transfers an image via PCIe to a Scaler II IP, processes it, and then sends it back to the host computer. My initial plan was to connect the PCIe IP to two mSGDMA ...

Hi Danield,


Thanks for reaching out.


Allow me some time to investigate your issue. I shall come back to you with the findings.

As you are using Agilex 7 I-Series, are you using F-Tile or R-Tile? Do you need to use the MCDMA IP, or can you switch to the F/R-Tile AVST IP?


Thanks.

Best Regards,

Ven

    Hi Ven,

    I’ve already found a solution.

    To answer your questions:

    • I’m using the R-Tile.
    • I didn’t specifically need the MCDMA. my goal was to find a solution that works regardless of the device or PCIe IP being used.
    • I preferred sticking with a PCIe IP that supports a memory-mapped interface, as I find it more flexible and convenient.

    The solution I settled on was transferring the image to an EMIF and connecting two Frame Buffer II IPs to it. one configured as a Frame Reader to send the image to the video IPs, and the other as a Frame Writer to return the processed image from the video IPs back to the EMIF.

    Best regards,
    Daniel
