Abstract:
An analog translator for the IEEE 1394 serial bus, comprising:a plurality of ports, wherein a plurality of analog devices can be connected to said ports; a status register for indicating which subset of said plurality of analog devices are connected to said ports, wherein each of said plurality of analog devices is assigned to a separate bit in the status register; a configuration ROM for storing information related to said subset of the plurality of analog devices that are connected; a controller for setting bits of the status register to designate status of the subset of analog devices that are connected, reading the status of the set status register, and recording on the configuration ROM a connection information of the subset of the analog devices that are connected, wherein said configuration ROM refers to the bit status of the status register, when an analog device is connected to the port; a 1394 interfacing unit for receiving a packet data from the IEEE 1394 bus, checking whether the packet data corresponds to a node thereof, and disintegrating packet data and removing a header from the packet data when the packet data corresponds to the node thereof; a storing unit for storing a payload data removed from the header; a destination unit extractor for decoding the payload data and extracting a destination information corresponding to the payload data; and a data translating unit for translating the extracted destination information into an analog signal.
