IEEE 1394 is a serial bus architecture for high-speed data transfer, serial meaning that information is transferred one bit at a time. Parallel buses utilize a number of different physical connections, and as such are usually more costly and typically heavier. [6] IEEE 1394 fully supports both isochronous and asynchronous applications.
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.
Other competing standards for external drive connectivity include eSATA, ExpressCard, FireWire (IEEE 1394), and most recently Thunderbolt. Another use for USB mass storage devices is the portable execution of software applications (such as web browsers and VoIP clients) with no need to install them on the host computer. [64] [65]
Drivers for OHCI-compliant FireWire 400 (IEEE 1394-1995) host controllers are removed, although they are available from Microsoft Support. Windows 8.x comes with drivers for FireWire 800 (IEEE 1394b-2002). [38] DirectDraw emulation, previously deprecated, now exhibits significant performance degradation in certain legacy games. [39]
Application software is allowed to access operating system APIs, but never should access any level lower. In the context of FireWire cameras, the high level drivers are responsible for the protocol. The low level drivers and the interface boards put the definitions of the standard IEEE 1394 into effect.
MMC driver: mmcblk: storage driver for MMC media (SD cards, eMMC chips on laptops, etc.) mmcblk0: first registered device; mmcblk0p1: first registered device's first partition; SCSI driver, also used by libATA (modern PATA/SATA driver), USB, IEEE 1394, etc.: sd: mass-storage driver (block device) sda: first registered device
Originally developed by the Personal Computer Memory Card International Association (), the ExpressCard standard is maintained by the USB Implementers Forum ().The host device supports PCI Express, USB 2.0 (including Hi-Speed), and USB 3.0 (SuperSpeed) [2] (ExpressCard 2.0 only) connectivity through the ExpressCard slot; cards can be designed to use any of these modes.
The Serial Bus Protocol 2 (SBP-2) standard is a transport protocol within the Serial Bus, IEEE Std 1394-1995 (also known as FireWire or i.Link), developed by T10. [1] Original work on Serial Bus Protocol started as an attempt to adapt SCSI to IEEE Std 1394-1995 serial interface. Later on it was recognized that SBP-2 may have a more general use ...
