I've been working on implementing this PCI core into the DSP/FPGA dev
card, and have been making good headway interfacing to the PCI core
from the DSP, dispite a lack of in depth knowlege of the PCI core.

I need to interface the 20bit Address bus of the DSP to the 32bit
address space of the PCI bus. My first thoughts were to have a
secondary address register that would hold the upper 12address bits.
This would work okay, if i partition the PCI cards accordingly.

I (personally) only plan to use 1 maybe 2 other PCI cards at a time,
and wont have to worry about trying to access many different address
spaces at once.

However, This may not be the best method. Has anyone ever attempted
this before? Or can anyone offer any other sugestions? (Besides get a
DSP with external 32bit interface :) )

Thanks,
