DM648 PCI master/slave data interchange example code desired

I'm working on a custom PC board containing two DM648 DSP connected to each other via their PCI buses.

I believe the hardware is connected correctly to support PCI communications between the two DSPs, but I'd like to hear any comments about
any difficulties you might have encountered in such a setup. (I am aware of the probable throughput problems from a PCI master)

I'd like to write a C program (using Visual Studio 3.3) that will run on both DSP and demonstrate communications between them across
their shared PCI bus, with one DSP acting as the PCI master and the other acting as the PCI slave.

Is there example code available that could be of help, or is there any application note that would contain an example I could make use of. 
I'm particularly interested in the setup of the PCI control registers of the DSP to enable operation of the PCI interface.

Thanks,
Jim
