Why FPGA
I'm not sure why folks hype the use of FPGA as a sign of performance. Except in the rarest of cases, field programmable devices merely serve as a way of producing custom devices without the overhead of full foundry silicon production. That's primarily a matter of production cost versus volume demand, but devices implemented on FPGA are often slower than what could be achieved by well designed dedicated foundry silicon, because the FPGA inevitably has a generic architecture that may not be optimal for any given function. However using FPGA does ensure that no third party has knowledge of your device function or internals, so it can be useful for protecting IP.
