Accessing specific memory in DMA

I am trying to interface fpga and yocto in DE2i-150 board using device driver. From software side I am using DMA for memory allocation. I have 3 input data. Two of them are 416 bit long and one is 32...

Thank you for your response. I have resolved that problem. Now I am facing another problem related to onchip memory range. I don't want to use Nios II. I just want to speed up the arithmetic computation I mentioned before using parallel ckt. I have implemented a custom logic for this which I have declared as avalon master. I am accessing memory upto 176byte and No of address bits required is 8. But whenever I am trying to connect custom logic avalon master to onchip memory s2, I am getting the following error: Error: System.gmm_0.avalon_master: shared_memory.s2 (0x0..0x1fff) is outside the master's address range (0x0..0xff). Memory size I have given as 8192byte. How to resolve this issue?
