Coprocessor Feature

    Hi Sir,


    I have gone through with the example applets provided in Visual applets installation directory and found an example in the path "C:\Program Files\SiliconSoftware\VisualApplets_3.2\Examples\Processing\CoProcessor\CoprocessorMedian" and the particular operator 'DMA From PC' has used in it. I Like to use the same feature in Marathon VCL framegrabber and noticed that the mentioned operator is only available for either VD1/VD4 framegrabbers. I wonder why it is not available for latest framegrabbers. Is there any alternative available? Can you please reply on this?

    Hello JSuriya,


    The DMAFromPC operator does only exist for "pretty old" VD1 frame grabbers.

    mE5 marathon/ironman is not supporting this operator for co-processor functionality.

    While the DMA approach could potentially support GB/s in the downstream (Host-PC-Memory to Grabber) there is a non DMA way to upload images with around 10 MB/s using an alternative register interface instead of DMA.
    What data-rates do you expect for your application?
    I know that 10 MB/s is pretty limited.


    Best regards,
