The NIOS ISA is a very simple load/store architecture. NIOS is optimized
for a decent implementation in an FPGA and thus it's not very fast. With
a Cyclone 3 it runs at most at some 125 MHz. My 100 MHz NEEK design
measured in a Linux application results in some 50..75 DMIPS.
OTOH you can implement custom instructions that might speed up certain
operations.
