Subject: [oc] Connecting single PCI device to FPGA
Hi,1. A PCI32 device can be controlled just by using some simple buffers
also; it all depends upon the exact application and the target device.
2. Using the PCI core at opencores also you can control a PCI32 target.
The opencores has a master as well as a target interface. For your
application you just have to remove the target part. Of course you will
have to do a lot because opencores PCI is made for WISHBONE bus. You
will to have to write some converter between WISHBONE and your
processor bus.
3. If you can provide some more details then I may be able to give some
more suggestions.
With regards
