    project on image processing in vhdl

    you have to put the image in matlab and get the matrix then convert it to binary values in a file and then read from the text file with binary values into vhdl

    how to load image to a block ram

    hello sir.....
    thank you for replying......

    if i do this whatever you said....
    then i would convert the image in matrix form in text file......

    but after that
    should i have to enter the matrix data in VHDL manually?????

    if it is then it is very tuff to enter data into VHDL....because i have to download that code on FPGA.....SPARTAN 3....and there are only 16 input pins.........

    so how can i enter data in VHDL..........?????

    if you get my problem and you know the solution of it....
    plz help me

    many thanks in advance

    vhdl progam on image processing

    you can convert to matrix then send this data to FPGA and then will put them in Ram .when you need to process just read back from Ram to use.I did my thesis about digital filter using this way. good luck

    image processing in vhdl

    thank you sir for your good suggestion.....

    did you mean that i can directly load matrix to FPGA RAM.......????????
    how can i do it????????
    should i have to write any program for that?????

    plz guide me sir

    fpga load an image into block ram

    yes using the i/o ports of your board you can send the image matrix to the ram....
    but i doubt whetther you can send the complete image (such large data) to ram of of your FPGA board i would suggest you to first see the ram size available on board.....And then proceed with your work.....

    It all depends on what kind of application you r working upon(for example some times you will have to write C codes to synchronize the data transmision and reception between board(that would work at faster clk) and parallel port(that works slowly) ).... It would be better if you would tell what you r working at so that the forum members can guide you in a better way....

    image processing vhdl example

    hello sir .........
    first of all for positive respone and suggestions.........

    i m working on a project motion estimation. in that i have to compare the two images for getting some motion vector . so i have to load the image that is i converted into matrix form. so now i have to call this data in my program.

    i have to download this program on FPGA kit.

    so, i m not understanding that how can i call this data in my program.?????
    should i have to store data in signal in VHDL program........or is ther any other
    option to store data directly to FPGA block ram or anything else...........

    i hope you got my point ........
    and help me also

    thanks in advance

    Image Processing in VHDL

    belong to size of the image,if small you can use block ram or if about 128 and bigger you shoud have a module ram interface and use external ram on board (if available) or connect a ram to FPGA.
