Transfer data from pc to fpga through fibra channel

Hello, 

 

 

I am looking for a solution to transfer images from PC to my FPGA board. I am using the Terasic DE5-Net board with a Stratix V FPGA. The board is connected by the USB Blaster cable to the PC.  

 

Is it possible to transfer the images via the fibra channel ?  

 

If you have any other ideas, please let me know.  

 

Thank you for your help.  

Morrison

You don't provide enough detail for anyone to give an informed answer. How big are the images? How fast to you need to transfer? How far?

 

Does it have to be this board? If so, it has 3 interfaces: RS422, SFP and PCIe.

 

RS422 is simple but slow. You could use an RS422 to USB cable.

 

The PCIe is fast but you would have alot of work to do.

 

I've never used SFP but I suspect it is not simple either.

Since that board supports OpenCL, you can use OpenCL for easy and fast communication with the board via PCI-E.

MRodr3, you don't say what you want to do with the images, but OpenCL is probably your best option as HRZ says. If you've never used it before, I'm not sure you will find it easy at first, but the "DE5-Net OpenCL User Manual" below gives a pretty good idea of what you need to do.
