Nios2 Performance

I just ran some benchmarks for an ARM922 and a NIOS2/f. Both were run with the same code and ran at 90MHz. I did benchmarks for interger multiply, integer divide, floating point multiply, and float...

Floating point calculations without floating point hardware is never fast. The fact that the ARM uses a barrelshifter for the floating point calculations would suggest it would have a speed advantage. The hardware that you used with the 'f' core was intended for integer math. Tacking a floating point device onto a Nios II core would close the gap.
