VHDL and SOPC together

Hello,

i'm currently working on cyclone III (ep3c120f780c7n) development board and try to do something without any idea on how to realize it

i made working the following project "cycloneIII_3c120_dev_niosII_standard" with the simple_socket_server and the web_server

now i would like to reuse this design but for a more specific application,

I have a camera (mt9m011) which is working after an I2C configuration and send me some pixels datas

what I want to know is : (how) can I put my vhdl code in that design to keep pixels in the ddr2 and then send this datas to the PC

any ideas is welcome because I am working on this since weeks without result and I don't understand verilog code as the top level code

thanks in advance

    Hello,

    1> Regarding loading the Camera Pixel Data to DDR:

    You can add a custom module, It has to do the following

    a) takes input from the camera sensor,

    b)write it into a fifo wrt to camera_clk and then read from the fifo wrt[with respect to] ddr_clk

    c) Then write it to the ddr by designing a simple avalon bus interface that supports the DMA component already available in the SOPC builder in VHDL/verilog

    DMA component is instanced to your design in the SOPC along with the custom component [above explained] you designed.
