Honored ContributorNios2 multiprocessor resource usage
For experiments with multiprocessing, I would like to build a multicore Nios2 system with a reasonable number of CPUs, say 16, with at least 4 kilobytes of private on-chip RAM per CPU. Would this f...

Honored ContributorThe processor core uses two M4K blocks if I remember correctly for the register file. The debugger module uses one as well so you might need to go light on dedicated on-chip memories in your design. You have external memory interfaces on that board so I recommend dropping some pipeline bridges into the system if you attempt to hook up 16 processor cores to the memory otherwise the Fmax of your system will take a pretty hefty hit.
See "Increasing System Frequency" in this doc for more information about where to drop the bridges down in your design: http://www.altera.com/literature/hb/nios2/edh_ed51007.pdf
