Final year project question, PCIe interface to GPIO?

Hello everyone, My group members and I are starting our final year project for computer engineering this week and I have a question about PCIe data transfers to the FPGA. We are provided with...

Sorry, two of your ideas will not work;

  • PCIe support requires specialized transceivers that do not exist on these boards.

  • OpenCL support is specific to a small range of latest-generation boards.

But 1GbE might be ok - at least the kits support that.

What is the data rate you need to achieve to your host PC?

Cypress just released their EZ-USB FX3 kit

This $49 kit has a USB 3.0 controller on it, and should provide >100MB/s transfers (depending on your PC).

The kit can be interfaced to the HSMC connector on the DE2-115 via an HSMC adapter board

which is also $49 (although when I ordered my kit, I just requested this board, and they sent it to me).

The kit already comes with Altera interface examples. I haven't tested them yet, but I will, so if you decide to go this route and get stuck, you can ask for advice.

Cheers,
