How fast are fpgas

Microsoft, no doubt in cooperation with Intel, has implemented using FPGAs in its datacenters and has a network of Microsoft is touting big benefits in terms of performance of Bing search, which now is computed partially by FPGAs, and flexibility. Whether this trend continues remains to be seen. So are these previously esoteric FPGAs about to go mainstream?

I think that for FPGAs to really take off two things are needed:. Intel is working hard on these issues, but these are very large hurdles to take.

If you're really that concerned with speed, though, why are you even considering a discrete logic processor? Until recently I was writing some VHDL for very fast pipelined FFTs which would have gone onto a Zynq or , never got around to finishing the project, company is about to go into administration, but ball park estimate for the high speed parts was MHz maybe even MHz.

Will have to put that project on the back burner for now. This is good though I don't want to solder 's. Any advice? Posts: Country:. I hadn't even checked the prices for the high end Zynq parts let alone the cost of a fps camera. Got a few Spartan3 dev boards knocking around and they manage 50MHz with no problems and even MHz if you are careful.

Designs that utilise the FPGA's internal architecture features e. Without lots of work, a video processing pipelines will run at about MHz. Gaze not into the abyss, lest you become recognized as an abyss domain expert, and they expect you keep gazing into the damn thing. Quote from: MK14 on August 04, , am.

I have run stuff on a Virtex Ultrascale at MHz, but this was only a handful of counters to provide triggering signals to other components. You synthesize your design in the target technology a particular FPGA and let the static timing analysis tools tell you what the minimum clock period is.

Or, you add constraints to the design in the first place, and then the tools will let you know whether they're met or not. The speed that your CPU will run will be based on your longest flop-to-flop delay in your synthesized design. These added together form the critical path of your timing, which you can inspect in the timing report output by the place-and-route tool. There are entire design disciplines devoted to making architectures that minimize this delay to get the most out of a given process - pipelining, parallel execution, speculative execution, and so forth.

For example a -2 Xilinx Artix is a ' MHz' part roughly speaking although it's capable of higher clock rates for highly-pipelined designs. When you interact with the FPGA synthesis and place-and-route tools, you will need to give constraints for your design. These tell the tool flow the target flop-to-flop delay you're trying to achieve. Get to know SDC - it will help you get the results you want. Altera and Xilinx have online communities for help with how to use SDC syntax and many other topics.
