Qsys SPI interface on Stratix III

Hello,

Here is what I am trying to do. I have a ROM and a NIOS II processor that reads from the ROM. Then I need an SPI interface between the NIOS II and an outside of the FPGA component to pass the data that NIOS II read from the ROM. How can I do that? I am a newby concerning Qsys tool and the components are there but I really don't know how to connect them and automate the procedure that I've just explained. I would be grateful for any help.

Thanks
