write in VHDL (or Verilog or SystemC), synthesize you piece of
hardware, plugin into PCI, have fun with most performant (in terms of 
speed)and efficient (in terms of energy consumption) solution

I like C, but in this context C can be replaced with any compiled language.

from my point of view C has the only advantage of running on nearly 
every platform. As I said above any of compiled languages would speed up
the code.

my 2 cents
