PCIe

PCI Express is a high performance, general purpose I/O interconnect defined for a wide variety of future computing and communication platforms.

Key PCI attributes, such as its usage model, load-store 5 architecture, and software interfaces, are maintained, whereas its parallel bus implementation is replaced by a highly scalable, fully serial interface.

PCI Express takes advantage of recent advances in point-to-point interconnects, Switch-based technology, and packetized protocol to deliver new levels of performance and features.

Power Management, Quality Of Service (QoS), Hot-Plug/HotSwap support, Data Integrity, and Error Handling are among some of the advanced features 10 supported by PCI Express.
