DapTechnology has extended the OHCI functionality in order to address certain limitations and to offer hardware support for the AS5643 protocol layer including its specific transmission timing requirements. We use our own FireLink Extended IP implementation which is fully OHCI compliant yet offers extra benefits referred to as Extended OHCI.
While standard implementations require significant host software support, the FireLink® Extended with the Mil1394 option can support this layer with significantly better timing as well as reduced host resource utilization. Examples of typical applications in aerospace & defense for the FireLink® Extended with Mil1394 option include command & control systems for space-based vehicles, missile guidance platforms, fighter aircraft flight control, as well as its implementation in avionics & IFE platforms for business and commercial aircraft.
For more information about the Extended OHCI functionality and FireLink® Extended please refer to the IP core section.
