Honored ContributorYou really should read about the altera streaming interface. it's not that long of a document (see the chapter on streaming) . Know that your FIR input is the "sink" side and the FIR output with signals is the "source" side .
http://www.altera.com/literature/manual/mnl_avalon_spec.pdf See the fir manual as well. You didn't give us enough to know how much you know about FIR filters or Altera products either. Do you know how to design an FIR ? DISPRO is an excellent free software for determining your FIR cofs.
