    Help design a video system with multiple cameras

    I need to read data from several camera and dump them into either high speed USB or Giga-E.
    Total Camera bandwidth 140Mb/s

    Cameras--FPGA---RAM(at least 16Mb)
    MCU with USB+GIGAE.

    One way is to use FPGA for everything including USB and GIGAE, but I have to write too much verilog code.
    I want to use the MCU that already has USB/GIGE feature, so FPGA put the data into RAM and MCU send it out through USB/GIGE. The problem is how does the MCU interface with the RAM? What is the optimal way?
    Seems it must go through FPGA so the read/write does not interfere. MCU has 16bit DDR1,2 interface logic. The RAM does not have dual interface like FIFO. right?

    Thank you

    I do not get the part where you say FPGA put the data in RAM and send it out through USB/GIGE.Please give some more details about that..

    Re: Help design a video system with multiple cameras

    This is all too vague. How many cameras? What standard are they? How do you get the camera data into ram?
