Connecting an RSA-Coprocessor to a NiosII System

Hi, I designed a rsa coprocessor in Verilog which has to take inputs and put outputs directly into Memory (since arguments are quite large, about 5 or 6 and 1024 bit each). So I made the Coprocessor ...

I have to connect it to other entities within SoPC Builder (i.e. the coprocessor should access to the SDRAM Altera IP core - via the Avalon Masters, I think, and I have connected it with them by now) and on the other side it should be accessible in some way by the processor for programming and control purposes (setting the data address, asserting the start signal, return the done signal and the return value address)...so I think I should have a mechanism to let the processor "see" the coprocessor input and output wires (start, reset, done, DATA_ADDRESS, DATA_LENGTH, RETURN_ADDRESS) in some way...
