  • Hi Xu Wei,
    If you are asking about video frame scaler, there is a scaler unit in the display subsystem.

    Thanks. May I know if there is any other standalone hardware module (or EDMA implementation)?

    Yes, You could ISP in TDA3x for scaling operation.

    In addition, there is a scalar in DSS as well, which you could use for inline scaling with display.

    The scaling module in TDA3x device is the Resizer(RSZ), which is in the ISP, which is in the ISS megacell (Imaging Subsystem). You should obtain the full ISS chapter that is not currently part of the TRM. There in the Resizer you can do upscaling, do downscaling, filtering, horizontal and vertical flipping and all kinds of similar things.

    Thanks,

    Alex
