Since we are in the arena of the FPGA; why not move this functionalities 
to hardware ?

A big plus of this kind of platform is co-designing systems with 
software and hardware. Block the hardware then replicating software 
solutions is not the best way.

Of course, this is the opinion of a hardware designer  ;)
