When one has a large FPGA available the real-time filtering and FFT an so
one can be done there.   The soft CPU would not have to do much, I'd think
only interface type jobs, network protocol stack and so on.

The best feature of the Nios II soft core is that the C compiler can
synthesize  an FPGA solution for the inner loops.  Another words the Nios
CPU can be extended with special application specific instructions.  With
such extension the soft core becomes a very powerful CPU.    Also Linus
does run on Nios II.  (as it also does on ARM)
