Spooling from FPGA to the PC

That's 960 K bits/second. Some serial cards go that fast.

You can use the parallel port of the computer. in ECP mode. I once reached

4Mbit/sec in an PC to PC communication without using DMA. You can find my program (Delphi 3.0) when searching for FastTransfer.zip. Well, even EPP should do it (theoreticaly 2Mbps).

Have a look at FT2232C from FTDIchip.com. It is a simple USB slave controller that comes with the USB drivers. These drivers provide an UART com port on your PC. So interfacing this with your application is really easy.

If your USB bus is not busy with other peripherals, you can get up to

8Mbit/s. So this should be sufficient for your application.

You could use the PC-interface part of our 'dlk' system construction kit, capable of doing data rates about 400-500 Kbytes/sec via the PC parallel port. All components of the ' dlk ' system construction kit including the source code can be used free of charge for not commercial applications or for evaluation purposes.

So if you have enough I/O´s left for implementing a parallel link to the PC, adapting our sources to Your (Cyclone) needs should do the work.

This sounds like audio data. How about buying an audio card with s/pdif in and hooking your DSP to that via the fpga.
