EVM6678 Video Input

Hi, guys!

I want to implement some motion estimation tasks on 6678 device.

For that purpose I'm intending to purchase the development board EVM6678.

How could I orginize real-time video input in this target (especially from analog camera)? Only via EMAC?

thank you.

    Sergey,

    You would need to have the output of the camera converted to support one of the high speed interfaces.  EMAC, SRIO and PCIe are the most likely candidates.  The AMC header on the EVM has the SRIO and PCIe pinned out on it.  There is an adapter card for the AMC header to PCIe header.  That said EMAC may be the simplest solution to up and running quickly.

    Thank you.

    But I'm really puzzled why such a condition has been formed into the market, that nobody creates and sells high-performance (I think 6678 for present moment) DSP development boards with popular video interfaces (composite/camera-link, etc.). Because it's absolutely clear, that a complex computer vision algorithm (video stabilization, image fusion, object tracking) needs the maximum DSP performance, and it's simply ridiculous to compare 8000 DaVinci MMACS with 320000 MMACS of Multicore DSP.

    So the only explanation that comes to my mind, that it's US goverment strategy thing )

    Sergey,

    Popular video interfaces tend to be for single channel processing and devices such as DaVinci line are great products for this type of application.  The C6678 focus isn't only video focused though you are correct it's processing power lends itself well to many image processing and vision algorithm task.  The processing power of the device consumes large amounts of data and requires high speed interfaces that can handle a variety of data traffic.  Thus PCIe, SRIO, Hyperlink, and SGMII are the primary interfaces. 

    Best Regards,
