Various methods and systems provide interfaces between legacy data buses such as MIL-STD 1553 buses and wideband data buses such as IEEE 1394 data buses. One technique for interfacing a legacy device to a wideband data bus includes the broad steps of receiving legacy data in a legacy format from the legacy device, acquiring a timeslot on the high-speed data bus for at least a portion of the legacy data, embedding the portion of the legacy data into the timeslot to thereby transmit the portion of the data on the wideband data bus, repeating the acquiring and embedding steps until all of the received data is transmitted on the wideband data bus. The timeslot may be, for example, an immediate timeslot obtained via an interrupt-type request, or an acknowledge-accelerated arbitration requested timeslot occurring during a recurring access window.
