Connecting single PCI device to FPGA by Unknown on Jul 16, 2007			Not available!
Hi everyone, I am very new to the PCI bus system but currently, my project requires me to access and control a single PCI32 device using the FPGA. The PCI device that I am trying to access is a PCI-32bit device working at 33MHz and the FPGA that I am using is a Spartan-3 FPGA. I would like to implement a simple hardware-based controller and would like to avoid implementing any cpu architecture on the FPGA. I believe finding a core is the easiest way to do this. If my understanding about the PCI bus system is correct, I believe I would need a core that could make your FPGA to interface and control a PCI32 device. However, I have tried looking at several PCI32 controller cores on the web, but it seems to me that most of the cores are for turning your FPGA into PCI32 device BUT not to control another PCI32 device. Please advise if my understanding is wrong. I would greatly appreciated any opinion from any of you on what is the easiest way to control a single PCI32 device using an 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.

Connecting single PCI device to FPGA by Unknown on Jul 18, 2007			Not available!
Hi, Thank you very much for the replies guys. My project aim is to get an FPGA to be able to communicate with the PC through a 1394b interface. To do this I am using a TSB82AA2 Lynx chip and a TSB81BA3 chip as a 1394b interface controller. Quoting from the datasheet: "The TSB82AA2 OHCI-Lynx operates as the interface between a 33-MHz/64-bit or 33-MHz/32-bit PCI local bus and a compatible 1394b PHY-layer device". Therefore, the FPGA will have to be interfaced as a PCI local bus to the TSB82AA2. Currently I am facing two problems: 1. How to control the Lynx Chip as PCI local bus, and 2. How, if Im using a PCI core, to actually connect the signals from the PCI core to the TSB82AA2 as both have the same exact signals on them. (For example, signal Request is an input on FPGA core as well as on the TSB82AA2) Thank you very much! Yasir p/s: Pankaj Pailwar, could you please explain: "A PCI32 device can be controlled just by using some simple buffers" Looks very interesting.
