[REVANASIDHA]

Dear Sir/Madam

 

 

My name is Revanasidha K Jambgi i am doing a project is to implement image processing algorithms such as (Sobel edge detection and color reduction for single image data) on FPGA

I have NEXYS3

board which has spartan 6. I request you to help me regarding this. I have  to load the image file into the FPGA board and should have an access toeach pixel of the image. Please send me the snap shots of the process. ORwrite me where i can get this stuff. I searched in web for days together
 but couldn’t find it.

Hello,

 

You can send a file to FPGA using Adept: http://www.digilentinc.com/Products/Detail.cfm?Prod=ADEPT2

I will tell you step by step how to do it:

1. Connect the board by USB and turn on the power. This means that the FPGA and RAM is powered.

2. Transfer the Image to memory using Adept -> Memory tab. On the right side you can see SPI Flash, BPI Flash and RAM options and you should select the memory that you want to use.

 

 

After this step, your image is saved in your memory and then you can write the FPGA with your configuration (data processing component). This will not delete the data from the memory.

 

3. Program the FPGA with your configuration (data processing component).

 

Unfortunately, if you want to use RAM memory, we don't have an example for Nexys3 but you can use NexysOnBoardMemCtrl.vhd file from the Nexys2: http://www.digilentinc.com/Data/Documents/Reference%20Designs/OnBoardMemCfg.zip
