PCI Express
For over a decade the computing industry has evolved around a standard board-level or chip-to-chip interconnect specification – PCI (Peripheral Component Interconnect).
PCI Express (PCIe) is the newest generation interconnect that reflects an industry trend to replace legacy shared parallel buses with high-speed point-to-point serial buses. PCIe enables faster and more scaleable transmission rates with reduced complexity and costs, while keeping pace with increasing processor and I/O bandwidth requirements.
To help chip designers easily and quickly incorporate PCIe into their designs, Mentor Graphics offers a full line of silicon proven, highly configurable PCIe IP cores.

A Technology-Laden Communications Interface for the Future
The increasing I/O bandwidth requirement and decreasing real-estate requirements of the end product necessitate the adoption of faster I/O interconnect technology. The latest PCI Express technology is the third generation of the Peripheral Component Interconnect (PCI) standard aimed at driving faster and more scalable transmission rates than PCI and PCI-X.
This paper provides an overview of the PCI Express technology including configuration and applications. Comparisons in terms of protocols between PCIe and PCI/PCI-X are also described.

PCI Express is the latest generation I/O technology for high performance chip-to-chip interconnect applications. The overall performance of the PCI Express system depends on how quickly the data flows from node to node and how efficiently the data flows from end to end.
This paper describes the conditions that affect the performance in PCI Express and the special role replay buffers play in achieving high performance. Further, how to decide the appropriate size of the replay buffers for your particular needs will also be discussed.
