You should use a PCI-to-"something" bridge, by "something" I

I doubt that the microcontroller can handle PCI in software way in
role of slave (in master it would be possible).
AFAIK the purpose of this project and list is to design a graphic card,
Renesas stuff are way out of scope and i don't even care about
looking at the datasheet...
PC104+ also has an ISA
section, but that is 16MHz? also too fast for a software slave..
PC104+ or PCI104 is a PCI bus using the same form factor as PC104
and most recent boards have dropped the 2.54mm pitch connector
and keep the 2mm pitch PCI signals, faster.
PC104 (ISA) is very easy to interface with the help of a few TTL parts
(5V tolerant) so the uC can be slow if needed, using a few latches to
do the handshaking and data buffering.
And we didn't even scratch the surface. Hardware and software
are related. PCI(104) is terribly complex.
In comparison, prototyping with ISA/PC104 is a breeze.
One reason why I keep industrial PCs around !
