On-Chip Memory Required?

Hello all, I am new to NIOS, but quite familiar with FPGAs otherwise. I'd like to setup a NIOS II processor on a design that is already in place. I'd like to keep the on-chip memory usage to a bare...

I understand the SOPC requirement for _some_ ram, for use as cache or registers, etc. But I would like to reserve most of the M9K blocks for other purposes, and it looks like on a EP3C25 I can only get about 32K before it is over utilized. And I just know the end code will need more space, considering the demo programs take 10-15k at least.

So, its not a problem to store my fpgaconfig + code on the CFI or EPCS flash, and it will automatically copy the NIOS code to a DDR or other off-chip if I so choose? Good to know... now to just figure out how to get it to work!

Any further insight will be highly regarded! Thank you!
