    Hi ,
    I am realizing a project which consists in making a program in VHDL of
    the treatment of image (detection of face in a stream video / image)
    in VHDL and implement it on FPGA Xilinx Spartan III.

    ...Now the problem is here : I need to extract a part of my origin
    image which is stored in a ROM. but I am clamped !!
    Can anyone helps me to program this extraction PLEASE !! & thank
    you very much ..i appreciate it


    have a great day

    1. You need to know how is the mapping of your image in the ROM
    2. Write a read ROM process for the ROM(read the ROM spec. and some
    basic vhdl book)
    3. Make FSM to read where you want from the ROM to your RAM/what every
    your treatment for the image
