摘要： Several local IEEE1394 buses are bridged together over a second bus type to create a global bus wherein each local bus node is able to address nodes across the global bus without the local nodes being aware of the bridging operation. A bridging device operates by translating local bus node addresses to a global bus for communication over the second bus type. Alternatively, the local bus node identification process is controlled by the bridging device operating as the root node to cause the local nodes to be identified with a node address that is unique for the global network. The second bus type operates as a backbone for the global network and can be any type of communication bus or network with capability to transport the local bus traffic. The bridging devices that interface the local IEEE1394 buses to the backbone contain portals specific to each bus type that can communicate data between the dissimilar buses.

摘要： A method and apparatus for receiving packets from a node within a first network in accordance with a first protocol. A descriptor associated with each received packet is read by a direct memory access (DMA) controller that stores the received packet. A value for a controllable parameter is selected to efficiently communicate the content of the received packet over a second network that operates in accordance with a second protocol. The information in the received packet is then organized into newly formed packets, the size of which makes them efficient for communication over the network in the second protocol. The newly formed packets are stored in a transmit line buffer and associated with a Protocol Descriptor. The Protocol Descriptor provides information to a transmit controller to allow the transmit controller to select and aggregate packets from the transmit line buffer in order to make efficient use of the second protocol.

摘要： USB 2.0 supports communication in low-speed (LS), full speed (FS) and high speed (HS). In the full speed mode, the wire segment between a hub and a device is terminated via a pull-up resistor 480 on the D+ data line on the downstream end of the segment. In the high-speed mode, both signal wires are terminated by the LS/FS driver 420 generating a single-ended zero via resistors 490. The device emulates a disconnect, while it operates in the high-speed mode, by activating the pull-up resistor 480. Including the D+ pull-up resistor is practically equivalent to an open end, enabling a reliable disconnect detection in the hub using the disconnection envelop detector 460. Detection of an (emulated) disconnect, triggers the reset en enumeration process. This allows the device to report a change in functionality without the user having to physically remove the device from the bus.
