Can Nios Read 128-bit-wide data?

I'm trying to add a new module.Gernerally saied , it is a RAM ， 128-bit-wide( that means 1 Word = 128 Bit)， 512Word. I also add a NIOS II Processor， and try to read ...

What exactly is your requirement?

If your requirement is that you must read a 128-bit data word in one clock cycle then you are going to have to either use a DMA controller or write your own little hardware component to do it.

If you're just trying to be efficient, using a DMA controller may not be the best solution if at the end of the day you've got to read the data using the NIOS anyway. Typically DMA is used when you need to transfer a large amount of data in as short amount of time as possible.
