Need some advice about selection of FPGA devices(probably with PCIe interface)

I see. Thanks:)

Interfacing your system to a cell phone is simple. You just use network programming. In which case, what is wrong with talking directly to a NEEK?

If you need more processing power than the NEEK can provide, then your FPGA hardware will always need to reside in a box (big FPGAs need proper cooling). If that box needs to be moved around, then the MaxExpansion cube and a laptop is a good solution. If not, a PCIe card in a desktop is fine.

You're starting by asking the *wrong* question, i.e., "What board?".

The question you first need to answer is "What processing?"

If your algorithms require lots of floating-point performance, then you will need to look at a high-end device, i.e., Stratix V. However, if your processing can be implemented using fixed-point math, then the Cyclone or Arria or earlier Stratix series devices would be ok.

Cheers,

Dave
