    using BRAM for loading pixels

    I'm doing image processing...i want to store my pixel values in BRAM...i have used rs 232 to take each pixel from PC to fpga.. i want to store each of these pixels into BRAM of virtex4 fpga if i'm using core generator is it necessary i have to use a .coe file?? can't i store pixels which are...

    Interfacing between ISE and EDK

    hello I'm doing image processing on FPGA. I have written VHDL code for UART and this is how I'm going to input my pixels. This code is working. Next I want to store pixels into DDRSDRAM for this I'm planning to use EDK because writing hardware interface will probably take a long time. I'm doing...

    [SOLVED] To send text file through rs232 to fpga

    hello everyone, i had written uart receiver module and baud generator module for baudrate:9600 bps in vhdl. This code is working properly for all 1 digit values. Now i want to send a text file containing datas such as eg: 123 56 234 175 34 100 how do i send this through rs232...

    To send a grayscale image from PC to fpga via RS232

    oky Sckoran so r u telling me i can send an image as such through hyperterminal?? My image files are in image file formats. I tried b/w 2 PCs but i cant do it. i havent got a data array. The 1 got through matlab is not like the pixels in my image. there are some pixels missing and all. (i found...

    To send a grayscale image from PC to fpga via RS232

    Thank u very much 4 ur ideas Sckoran Hyperterminal can take text files. It has worked 4 PC 2 PC communication. Now i only need 2 convert my image into a text file. And then write a vhdl code 4 receiving each pixel. Problem is the conversion of image to text file.

    To send a grayscale image from PC to fpga via RS232

    Is it possible to send a grayscale image matrix from PC to fpga via RS232. If yes, how do i input this matrix in hyperterminal?? i'm planning to store the image pixel values in a text file. Is there any particular format in which i need to store these pixels, like binary, ascii etc?? I'm doing...
