Devices on a FireWire bus can communicate by direct memory access (DMA), where a device can use hardware to map internal memory to FireWire's physical memory space. The SBP-2 (Serial Bus Protocol 2) used by FireWire disk drives uses this capability to minimize interrupts and buffer copies. In SBP-2, the initiator (controlling device) sends a ...
The FireWave is a device that is, essentially, an external FireWire soundcard made by Griffin Technology as a third party accessory for Apple Inc.'s line of personal computers. FireWave uses the FireWire (IEEE 1394) port of the Mac as an audio output to its Dolby Digital sound processing hardware, effectively acting as an external soundcard.
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.

The FireWire interface allows all 8 inputs (counting stereo channels as 2) of the Helix Board 12 FireWire to be sent to a computer for recording, through its ASIO drivers (no drivers are required for the Mac). The main stereo output of your computer can also be sent through the FireWire interface, back to the Helix Board.
If you’re looking to connect a bunch of USB devices—and don’t need Ethernet, SD, VGA, or HDMI connections—look for an adapter with USB 3.0 ports (the current standard for USB-A). How We ...
Download time may take 10-15 minutes over dial-up. Call 1-888-265-5555 to order a CD for faster installation.
Following this approach, application software is in charge of the protocol. Since this solution utilizes the computing resources in a very efficient manner, it is still used in the context of highly specialized, industrial projects. This strategy often leads to problems, using other FireWire devices, as for instance hard disks.
