Recently I am dealt with a problem of construction PCI of the bridge for DC.
Having seen a code from dreamcast/dev/g2 and written test fragments for the analysis of conditions of bus G2.
I managed to develop the electronic scheme of the device.
It consists from:
SRAM Bufer for PCI DMA
At present I am engaged in its debugging.
At the first stage the main thing is debugging of a part responsible for access to configuration space PCI and io ports.
For me there is opened a question with realization of interruptions.
