Hi,
The following two articles are really good:
How PCI express devices talk (Part I): http://xillybus.com/tutorials/pci-expre ... al-guide-1
How PCI express devices talk (Part II): http://xillybus.com/tutorials/pci-expre ... al-guide-2
They clarified my basic doubts/questions about PCIe interface.
Thanks for sharing it.
Regards,
