The xHCI eliminates host memory based USB transaction schedules, enabling zero host memory activity when there is no USB data movement. The xHCI reduces the need for periodic device polling by allowing a USB 3.0 or later device to notify the host controller when it has data available to read, and moves the management of polling USB 2.0 and 1.1 ...
Open Host Controller Interface (OHCI) [1] is an open standard.. Die shot of a VIA VT6307 Integrated Host Controller used for IEEE 1394A communication. When applied to an IEEE 1394 (also known as FireWire; i.LINK or Lynx) card, OHCI means that the card supports a standard interface to the PC and can be used by the OHCI IEEE 1394 drivers that come with all modern operating systems.
USB 3.0 SuperSpeed – host controller (xHCI) hardware support, no software overhead for out-of-order commands; USB 2.0 High-speed – enables command queuing in USB 2.0 drives; Streams were added to the USB 3.0 SuperSpeed protocol for supporting UAS out-of-order completions USB 3.0 host controller (xHCI) provides hardware support for streams
Most initial boards shipped without USB headers due to a fault with the integrated USB controller. Manufacturers included PCI USB cards to cover this shortcoming. A later refresh of the chipset had the USB problem remedied. [2] AMD-8000 series chipset AMD-8111 Apr 2004 Opteron: 800 (HT 1.x) AMD-8131 AMD-8132 Hardware RNG
Host Controller Interface (USB), an interface that enables a USB host controller to communicate with a driver; Host Controller Interface (Bluetooth) in Bluetooth protocols; Host Controller Interface (non-volatile memory), an interface that enables SATA Express / NVM Express SSDs to communicate with a driver
One USB xHCI controller supporting three USB 3.0 ports, two SSCI ports, and two HSIC ports; One USB xDCI controller supporting one USB 3.0 port; Integrated LPE audio controller; Integrated image signal processor supporting three MIPI CSI ports and 13 MP ZLS sensors; Integrated memory card reader supporting SDIO 3.0, eMMC 4.51, and SDXC
The Yangtze FCH features support for two USB 3.0 ports, two SATA 6 Gbit/s ports, as well as the xHCI 1.0 and SD/SDIO 3.0 protocols for SD-card support. [60] Both chips feature DirectX 11.1-compliant GCN -based graphics as well as numerous HSA improvements.
Inter alia with Windows 10 and 8, this can be fixed by forcing the correct drivers to reload during Safe Mode. [9] In Windows 8, Windows 8.1 and Windows Server 2012, the controller driver has changed from msahci to storahci, [10] and the procedures to upgrade to the AHCI controller is similar to that of Windows 7.
