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...

Rick,

I am no expert when it comes to floating point but I think there is a tool at your disposal that can help answer this: the .objdump. I'm assuming you know how to create one for Nios II -- it will show you what happens in the GNU FP libs... is it possible to get the equivalent for the arm processor and take a look?

Don't forget that several users have posted various bits of FP hardware to this forum that should integrate nicely with Nios II; perhaps another part of your analysis could include wiring one of these up, comparing performance again, and then factor in the cost (from additional LE usage) to make things fair?
