    The standard nios design given with the kit uses the SD-Ram as main memory for the Nios CPU.

    If you use the small library/driver versions you should be able to get something that will fit in the internal memory.

    You should also be able to use the sram (I've no idea how big that might be!).

    thank you!

    there is no SD-ram ,only has DDR2 ,SRAM,FLASH.

    the example of "dk" use ddr2 in the project,but I think that is not a good example

    DDR2 is sdram and can be used by the Nios CPU. I don't see where the problem is.
