HiI have a DDR3 Memory with the HMC. I have som important Data (Nios Instruction and Data) and some nonimportant Data (from external). Both process have to write into the RAM. I now realized, that this would be possible with the HMC sind I have there two Avalon Busses. But the problem is, both are pointing on the same Memory with different adresses. I'm ok with different adresses. But the Problem is the following: I want to use Avalon_0 for my NIOS and Avalon_1 for external Data. How do I set a maximum size of Avalon_0/1 so that they don't get overridden by the heap etc?

You could try use the address span extender to create a window like view into the Avalon interface so that the masters see different base addresses. And you can split the memory to 2 logically.
