PS/2, serial port, parallel port, game port, etc., and host power consumption was not an important consideration at the time. When USB was originally developed in 1995, it was targeted at desktop platforms to stem the proliferation of connectors that were appearing on PCs, e.g.

The xHCI architecture was designed to support all USB speeds, including SuperSpeed (5 Gbit/s) and future speeds, under a single driver stack. The OHCI and UHCI controllers support only USB 1 speed devices (1.5 Mbit/s and 12 Mbit/s), and the EHCI only supports USB 2 devices (480 Mbit/s).
Define an extensible architecture that provides an easy path for new USB specifications and technologies, such as higher bandwidth interfaces, optical transmission medium, etc., without requiring the definition of yet another USB host controller interfaceĪrchitectural details Support for all speeds. target host controller power, performance and cost trade-offs for specific markets Provide the ability for different markets to differentiate hardware capabilities, e.g. Enable hardware "fail-over" modes in system resource constrained situations so devices are still accessible, but perhaps at less optimal power/performance point. Eliminate the "Companion Controller" model. Eliminate register writes and minimize register reads for normal data transfers. Minimize host memory accesses, fully eliminating them when USB devices are idle. Decouple the host controller interface presented to software from the underlying USB protocols. A device level programming model that is fully consistent with the existing USB software model. Efficient operation – idle power and performance better than legacy USB host controller architectures. the Open Host Controller Interface (OHCI), the Universal Host Controller Interface (UHCI), and the Enhanced Host Controller Interface (EHCI)) on many counts.įollowing are the key goals of the xHCI architecture: The xHCI is a radical break from the previous generations of USB host controller interface architectures (i.e. XHCI improves on the pre-existing Open Host Controller Interface (OHCI) and the Universal Host Controller Interface (UHCI) architectures most prominently in handling a wider range of speeds within a single standard, in managing resources more efficiently for the benefit of mobile hosts with limited power resources (such as tablets and cell phones), and in simplifying support for mixing of low-speed and high-speed devices. The specification is also referred to as the USB 3.0 host controller specification. ( April 2014) ( Learn how and when to remove this template message)ĮXtensible Host Controller Interface ( xHCI) is a computer interface specification that defines a register-level description of a host controller for Universal Serial Bus (USB), which is capable of interfacing with USB 1.x, 2.0, and 3.x compatible devices.
