ASB to PCI bridge - wilton peter - Mar 5 5:14:00 2003

Hello All, Could anyone here tell me where I can find some vode on the AMBA/ASB to PCI bridge? I'm using the CARMeN-Xilinx v3 board. There is an ARM7 processor and a PCI slot, connected through a virtex-e FPGA on the board. I want a kind of bridge which can let the ARM processor (with ASB interface) to access the PCI card, Thanks youy kind help in advance and, have a nice day Wilton -- _______________________________________________ Get your free email from http://mail.usa.com |

Hi, I saw an fishbone to PCI bridege at opencores.org. fishbone is a simple embedded bus like ASB. I think u can change fishbon einterface to ASB, and it is not very difficult.

Dear Sir, First of all, thanks your kind information very much. Is it fishbone or Wishbone? I just found Wishbon at opencores. Another question is, It looks like a add-in card application which has a cpu with wishbone interface on that Add-in CARD. But what I'm looking for is something like the north-bridge on the motherboard (with ASB as host interface). I already have the PCI card, which has gnt and idsel signals as inputs, INTA as ouput (as specified in PCI spec.) I want something to control this PCI CARD, not a PCI add-in card with ASB interface. I hope I made myself clear. Could u pls suggest is there anyway to change the wishbone/pci bridge to fulfill my requirement? Or is there any other core available? Thanks again and have a nice day, Wilton ----- Original Message ----- From: hadi khani <> Date: Fri, 7 Mar 2003 22:18:42 -0800 (PST) To: Subject: Re: [fpga-cpu] ASB to PCI bridge > Hi, > > I saw an fishbone to PCI bridege at opencores.org. > fishbone is a simple embedded bus like ASB.

Hi, You are right. It is a PCI controller for Add-in card. I do not know anything else. if u find more let me know. bye --- wilton peter <> wrote: > Dear Sir, > > First of all, thanks your kind information very > much. Is it fishbone or Wishbone?

Hi Wilton, in general there is no big difference between a host-based PCI I/F and a so-called satellite mode PCI I/F(PCI add-in card), with three exceptions ! Both host and satellite PCI I/F have to have a PCI Target I/F and might have (in case of a host - should have) a PCI Master I/F. By the PCI Target I/F the host I/F shares other system resources as host memory for example. THE three exceptions: 1. Arbiter : A host based PCI I/F needs to have a arbiter for the PCI bus. The arbiter determines which if the masters (requesting the bus by REQ#) grants the bus (by GNT#). Arbitration scheme is not determined by PCI specification, but something like (prioritized) round robin is recommended. 2. CLK source: The host based PCI I/F needs to provide the PCI clock for all other PCI I/F's (e.g. slots on the motherboard). 3. INT sink: In order to do something useful in case of a INTA#...INTD#, some kind of interrupt controller in conjunction with a CPU (capable to run an ISR) might be needed :-)! Reset of INTX depends on the device that issued the interrupt. So all you might have to do in your case is to connect the Master I/F of the Wishbone core (backend- or CPU-side) and to 1. configure the PCI target of your PCI card (set base adress register, enable in command register,....) 2. Configure your own target (if memory sharing or something equivalent is necessary) 3. Start the PCI device on your card (e.g. set some register in the PCI target space) Hope that helps a bit.
