Interfacing a legacy data bus with a wideband data bus utilizing an embedded bus controller

摘要

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 bus to a wideband data bus involves providing a hybrid bus controller/remote interface unit as an interface between the two buses. In operation, the legacy interface suitably receives data intended for a legacy node from a wideband data bus capable node. The legacy data is converted in the legacy interface/remote interface unit to at least one legacy word having a legacy format for transmission on the legacy data bus. The legacy interface may be further configured to receive a reply to the wideband data bus capable node message from the legacy component on the legacy data bus, and to forward the reply to the wideband data bus capable node component.
