FGPA = Field Programmable Gate Array.

Basically, you can create a custom "CPU" for your particular workflow. Imagine the GPU didn't exist and you couldn't multiply vectors of floats in parallel on your CPU. You could use a FPGA to write something to multiply a vector of floats in parallel without developing a GPU. It would probably not be as fast as a GPU or the equivalent CPU, but it would be faster than doing it serially.

Another way to put it: you can create a GPU with a FPGA, but not vice versa.

Thanks. But what's the capacity of this particular FPGA? How much can it "do" ? Surely it can't emulate a dozen Xeons; so what's the upper bound on what can be done on this FPGA?
