even though PCI is truly typical it typically doesn’t see experimentation by amateurs since of its high performance nature. ChaN chose to develop a system to demonstrate that PCI is within the reach of hobbyists. He does this with just 1 GAL, 2 identity comparators, as well as 4 latches. To pull this off a couple style guidelines have to be violated. For example: There is no configuration register so the target address has to be set with DIP switches. Something you would never see in genuine life. ChaN has been publishing electronics jobs for rather a few years as well as his site is well worth even more investigation.
