    摘要: An interface circuit that can disconnect a loop connection among nodes. The interface circuit includes ports, which are connected to bus cables, a state machine and a port controller, which is connected to the ports and the state machine. The state machine determines that a loop connection exists when a process in a predetermined state has been stacked for a predetermined time. When a loop connection exists, the port controller electrically disconnects a port on the loop.

    摘要: An interface circuit including an interface controller operated by at least a system power supply or an external power supply. A switch is connected between an interface controller and a system power circuit for conducting system power. The interface controller includes a control signal generating circuit for generating a control signal that closes the switch at a timing that does not affect data transmission performed by the interface circuit in accordance with a trigger signal, which indicates that the system power has gone on. Similarly, the switch is opened at a time when data transmission will not be affected.

    摘要: A packet transfer control circuit is a part of a node in a network of nodes, in which packets of data are passed between the nodes. The packets include normal packets and write packets, and each packet includes a header portion and a data portion. The transfer control circuit includes an identification circuit which identifies if the data portion of a write packet is blank and a processor with a memory connected to the identification circuit. If the write packet is blank, as determined by the identification circuit and the processor is holding data for transmission to another node, the processor puts the data into the data portion of the packet, zero fills if the there is not enough data to fill the data portion, updates the header with the new addressee, and then passes the write packet on to the other nodes.

    摘要: An IEEE 1394 compliant bus controller transfers data packets between connected nodes. The controller includes a processor which divides a series of data into blocks and then stores the blocks in multiple packets (one block per packet). The packets are then transferred over the bus from a source node to a destination node at equal intervals until the entire series of data has been transferred. An initialization prohibition unit prohibits initialization of the nodes during the data transfer which may be caused, for example, by hot plugging (connecting a new node to the bus) during the data transfer.
