Systems and methods for interfacing legacy equipment to high-speed data buses

A method of transmitting MIL-STD 1553 data over an IEEE 1394 data bus, the method comprising the step of:

• receiving the MIL-STD 1553 data from a legacy device at a remote interface unit;
• initiating an immediate packet transmit request from the remote interface unit to obtain a timeslot on the IEEE 1394 data bus;
• delaying transmission from the remote interface unit on the IEEE 1394 data bus for at least a pre-determined period of time, wherein the pre-determined period of time is based upon the maximum message length allowed on the IEEE 1394 data bus;
• transmitting at least a one-word portion of the MIL-STD 1553 data from the remote interface unit on the IEEE 1394 data bus after the pie-determined period of time has elapsed;
• and
• repeating the initiating, delaying and transmitting steps until all of the MIL-STD 1553 data is transmitted on the IEEE 1394 data bus.

A method of transmitting MIL-STD 1553 data over an IEEE 1394 data bus, the method comprising the steps of:

• receiving the MIL-STD 1553 data from a legacy device at a remote interface unit;
• initiating an acknowledge-accelerated arbitration request from the remote interface unit on the IEEE 1394 data bus to establish a priority window on the IEEE 1394 data bus;
• transmitting at least a portion of the MIL-STD 1553 data on the IEEE 1394 data bus during the priority window;
• and
• repeating the initiating and transmitting steps until all of the MIL-STD 1553 data is transmitted on the IEEE 1394 data bus.

A system for interfacing a legacy device with a high-speed data bus, the system comprising:

• means for receiving data in a legacy format from the legacy device;
• means for acquiring a timeslot on the wideband data bus for at least a portion of the data;
• means for embedding the portion of the data into the timeslot to thereby transmit the portion of the data on the wideband data bus;
• and
• means for repeating the acquiring and embedding steps until all of the received data is transmitted on the high speed data bus.

A system for interfacing a legacy device with a wideband data bus, the system comprising:

• a first code module configured to receive data in a legacy format from the legacy device;
• a second code module configured to acquire a timeslot on the wideband data bus for at least a portion of the data;
• a third code module configured to embed the portion of the data into the timeslot to thereby transmit the portion of the data on the wideband data bus;
• and
• a fourth code module configured to repeat the acquiring and embedding steps until all of the received data is transmitted on the high speed data bus.

A data processing system providing an interface between a legacy bus and a wideband bus, the system comprising:

• a legacy input/output module in communication with the legacy bus;
• a PHY layer module in communication wit the wideband bus;
• a LINK layer module in communication with the PHY layer module;
• and
• a processing module configured to communicate with the legacy I/O module and the LINK layer module via an input/output subsystem, wherein the processing module is operable to receive legacy data from the legacy bus via the legacy I/O module, to request a timeslot on the wideband bus for at least a portion of the legacy data via the LINK module, and to transmit the legacy data on the wideband bus using the timeslot.
