Aiming to prove it doesn't actually want USB 3.0 all for itself Intel has now made available the 0.9 draft specs of the Extensible Host Controller Interface (xHCI) which is set to be used for the upcoming SuperSpeed USB architecture. This specification describes the registers and data structures used to interface between system software and the USB 3.0-compatible hardware currently in the works and is a vital thing for the quickly deployment of the USB 3.0 standard which is set to offer maximum transfer speed of 4.7 Gb/s.
"The future of computing and consumer devices is increasingly visual and bandwidth intensive," said Phil Eisler, AMD corporate vice president and general manager of the Chipset Business Unit. "Lifestyles filled with HD media and digital audio demand quick and universal data transfer. USB 3.0 is an answer to the future bandwidth need of the PC platform. AMD believes strongly in open industry standards, and therefore is supporting a common xHCI specification."
As previously promised, the xHCI specs are offered for free but only to members of the USB 3.0 Promoter Group and contributor companies that sign an xHCI contributor agreement. A revised xHCI 0.95 specification is also in the works and will be released in Q4.
