QUESTION: PCI to ISA coding? by Richard on Jan 17, 2006			Richard Posts: 9 Joined: Mar 4, 2002 Last seen: Jan 27, 2025
hello, Although I've done PLD design off and on over the past 15 yrs; I've yet to do my first FPGA project. So please bear with my ignorance... I have a legacy ISA motion-control board which needs to be converted to PCI bus format. We cannot redesign the entire motion system; so we need to be able to "replicate" the ISA card on a PCI board. This is to avoid any modification of the software application; other than the bare minimum of changing the addresses of the port I/O, if needed. I should mention that there is -nothing- fancy going on over the ISA bus. All the card/PC does is simple Port-I/O, plus a single IRQ line. No DMA, no memory-type accessing, nothing at all other than port-I/O in a single 8-address block. I have looked at the PLX PCI9052, however it is a costly part, and if I have to do a redesign anyway, I'd very much like to collect all the 74HC glue logic into one part. As well as converting the entire through-hole board into a totally SMT design. So I'm very attracted to the idea of using a single FPGA to perform both the PCI-intfc job of the 9052 and all other logic functions of the board. My questions are these: 1) The PLX part has a "mode" where it basically emulates an ISA bus. Does the OpenCore PCI core have this functionality? Since the application is all about timing of pulses etc., it is important that the card-side of the PCI-interface act just like an 8mhz ISA slot. 2) Is it possible to set up a PCI-card so that it responds to the same port-I/O instructions as an ISA card would ? In other words, can the PCI card be set up so that it looks to the CPU like an I/O port at, say, 3F8. What I'm trying to get at is this: can the PCI card be made to work in place of the ISA card -without- having to modify the application-software in any way? And -without- having to write any sort of seperate 'device driver'. (I cannot modify the software to look for / talk to a device driver. I -can- modify what port-addresses it calls, if need be) It would be a huge benefit if the software didn't need to be touched; as the original programmer is years gone. 3) If I understand the terminology correctly; all I need is a simple "slave" or "target" PCI interface. Is that correct? 4) I also need to emulate an AD7628 dual 8b DAC. I plan on using a counter/PWM setup in the FPGA. If anyone can point to tutorials or examples of how to do this in the most gate-efficient way, that'd be great! If you'd be kind enough to cc replies to my email, I'd be grateful. thanks very much!

Hello Richard. I think that I have solution right for you. I have developed a simple PCI Target core witch suits your requirements exactly. I have done many such projects, all works fine. I can emulate ISA card so no single line of software has to be modified. Addresses and interrupts can be hardwired, or P&P (jumper selectable). All in simple and cheap ALTERA MAX3000 or ACEX1K parts. I can integrate rest of You project in ALTERA CPLD/FPGA I'm sorry for my english. It's not my native language. I live in Poland-Europe. If you interested, please contact me. best regards Wojtek. ----- Original Message ----- From: "Richard" <<A HREF="http://www.opencores.org/mailman/listinfo/pci">metal at fullwave.com</A>> To: <<A HREF="http://www.opencores.org/mailman/listinfo/pci">pci at opencores.org</A>> Sent: Tuesday, January 17, 2006 8:39 AM Subject: [pci] QUESTION: PCI to ISA coding?

Hi Richard, For this type of interface maybe a big CPLD would be better than a FPGA. They are live on powerup and can withstand +5v on their IO's, with new FPGA's ALTERA Cyclone, XILINX Sparten 3E you would need protection such as FET bus switches to protect the PCI pins. The Lattice website has a complete simple PCI target design you can download as long as you agree to use only Lattice parts. I found it a help even though in the end I did my own target design.
