configuration of nois2

I would read the Avalon documentation on this page first: http://www.altera.com/literature/quartus2/lit-qts-sopc.jsp (http://www.altera.com/literature/quartus2/lit-qts-sopc.jsp)

There is also this document that talks about hooking up an external master (DSP device): http://www.altera.com/literature/an/an397.pdf (http://www.altera.com/literature/an/an397.pdf)

What you are looking for are details on creating Avalon masters. As long as your master follows the Avalon switch fabric specification you should be all set. Sorry I can't be of more help but there is no single answer for the question you have asked.
