<strong>PCIe</strong> <strong>Devices</strong><br />
n<br />
Same definition as for PCI and PCI-X devices<br />
with the following additions/modifications<br />
l<br />
l<br />
<strong>PCIe</strong> devices must be compliant with ‘legacy’ operating<br />
system plug-and-play software utilities<br />
– Means PCI enumeration, configuration, device driver,<br />
application, and, if applicable, interrupt utilities<br />
– <strong>PCIe</strong> devices (accept the Root Complex) must implement PCI<br />
required and optional configuration space<br />
• May optionally implement <strong>PCIe</strong> optional configuration space<br />
Connections between <strong>PCIe</strong> compliant devices is now over a<br />
serial link<br />
– Communications over the link is controlled by an <strong>PCIe</strong> three<br />
layer protocol stack<br />
