Honored ContributorHi, we do have some numbers but nothing close to what you're looking for.
With the 2.6.9 kernel (that came with Nios II Linux v1.3), on a Stratix Development board running at 50Mhz, we were able to achieve roughly 8Mb/s during a Flood Test... there are other numbers as well but nothing that's directly comparable at this point in time. We've also been working on custom instructions to try and optimize the memcopy in uClinux. Some of our tests with the Opencores.org EMAC have shown an increase in throughput under certain conditions (i.e., no hardware multiples in the core). But again, I don't know if we'd ever be able to get up to 70Mb/s throughput... Hope this helps...
