Interconnects
PCIe
PCIe is a third generation I/O architecture that enables cost competitive, next
generation I/O solutions providing industry leading price/performance and feature
richness. It is an industry-driven specification.
PCIe defines a basic set of requirements that comprehends the majority of the targeted
application classes. High-end application requirements such as Enterprise class servers
and high-end communication platforms are delivered by a set of advanced extensions
that compliment the baseline requirements.
To guarantee headroom for future applications of PCIe, a software-managed
mechanism for introducing new, enhanced capabilities in the platform is provided.

Config/OS
PCIe Stack Structure
The PCIe physical layer consists of a differential transmit pair and a differential receive
pair. Full-duplex data on these two point-to-point connections is self-clocked such that
no dedicated clock signals are required.
The bandwidth of this interface increases linearly with frequency.
