hello all,

i'm developing an application with two or more nios ii processors. there is a scheduller that select a thread to execute on a specific cpu. any thread can run on any cpu. however, there is no support to any cache coherency mechanisms in nios ii, and i can't disable explicitly the cache.

That&#39;s a known problem... If you want, take a look at the erika enterprise multicore support for nios 2 (http://www.evidence.eu.com/nios2) web page, we solved most of these issues related to multicore support in Nios II...

In any case, most Nios II designs are eterogeneous multicores, and migrating tasks over CPUs is not the most efficient thing to do, unless you are doing it for research purposes.
