Master Thesis on Cyclone V with DDR3 - Image Processing

Rather than spin your own board for your project, why not just use a devkit with some add on expansion boards?

This one has two HSMC expansion ports so you can have two daughterboards:

Here's a motor control HSMC daughter board:

Or if you can't find an HSMC daughter board that will do exactly what you need, why don't you go ahead and spin your own

HSMC daughter board

and leverage one of the pre-existing FPGA development kits for interfacing with it.
