How do you access RAM in a standard micro controller? With a function? No. You just define some variables and the linker "places" these into the RAM. Since NIOS *is* a standard micro controller it's the same method here. Tell the linker to use your RAM as for the rwdata or the stack or the heap...

In case you already have a RAM for your variables and want to use an additional RAM you have to use pointers for reading and writing to the additional RAM, as Daixiwen said.
