Design Considerations

PCI Express® takes the best features and ideas behind PCI and combines them with more than 10 years of industry “lessons learned.” The result is a robust, scalable, flexible, cost-effective I/O interconnect that will serve the industry for the next 10-15 years.

Key Features

•PCI Express architecture is an industry standard high-performance, general- purpose serial I/O interconnect designed for use in enterprise, desktop, mobile, communications and embedded platforms.

•It is PCI-compatible by using the estab- lished PCI software programming models. PCI Express facilitates a smooth transition to new hardware and allows software to evolve and leverage the advantages of PCI Express features.

•Gen I has a scalable bandwidth of 16 Gigabytes-per-second at its initial signal- ing rate of 2.5GHz. In the future, Gen II promises much higher transfer rates using higher frequency signaling technologies.

•Supports multiple interconnect widths via 1, 2, 4, 8, 12, 16 and 32 lane configura- tions aggregated to match application bandwidth needs.

•Serves new and innovative, hot-plug/ hot-swap add-in card and module devices.

•Delivers unique, advanced features such as Power Management, Quality of Service and other native functions not available in other I/O architectures.
