What is the right SOPC compenent for dcfifo?

Hi,

what I'm trying to do is the following:


I have an two DCFIFO as mega function outside the nios system .


I would like to have a avalon component(s) that connect to first DCFIFO component and transfers the first DCFIFO data 1000 words to an onboard SRAM.
I would like to have a avalon component(s) that connect to second DCFIFO component and transfers to the second DCFIFO 1000 words from an onboard SRAM.




In the Nios II software . After the transfer is done I would like to get an interrupt in the Nios II.




It would be great if somebody can point me to the exact SOPC components and avalon interface specification I need for this task.


Thanks in advance,
ofer
