摘要： Techniques for improving the quality or fidelity of a digital signal transmitted via a two-wire bus interconnect utilizing an open-terminal configuration at one or both end devices of the bus interconnect are disclosed. An intermediate two-wire bus is used to connect two open-terminal-based two-wire busses. A bus adapter device is utilized at each end of the intermediate two-wire bus, whereby the bus adapter device communicates signaling on the corresponding open-terminal-based two-wire bus using open-terminal ports and communicates signaling on the intermediate two-wire bus using push-pull ports. The bus adapter device can utilize control logic to implement a state machine or other function to control the interactions between the different two-wire buses. The bus adapter devices may be implemented as interchangeable integrated circuit devices that can change configuration based on connection, thereby permitting their implementation at either end of a bus transmission system.

摘要： Transmit-side active signal management circuitry applies one or more active signal management processes to a digital signal at a transmit side of an interconnect. At the receive side of the interconnect, receive-side active signal management circuitry applies one or more corresponding active signal management processes, as appropriate, to the received digital signal to recover the information represented by the original digital signal. The interconnect can include a cable used to transmit the signals between a source device and a destination device, whereby one or both of the transmit-side active signal management circuitry and the receive-side active signal management circuitry is implemented at a corresponding cable receptacle of the cable. Alternately, one or both of the transmit-side active signal management circuitry and the receive-side active signal management circuitry can be implemented at a cable adaptor, thereby permitting the use of a passive cable interconnect to transmit the signal.

摘要： A crossbar routing arrangement is disclosed for use in a digital system having three or more buses. An associated method is also disclosed. The routing arrangement is configured for transferring a set of data received from any particular one of the buses to any other selected one of the buses and includes a control arrangement associated with each bus for dividing the set of data into at least first and second subsets of data and for adding self-routing signals to each data subset which signals identify the selected bus. A switching arrangement is configured for directing the first and second data subsets in a predetermined way responsive to the self-routing signals. The control arrangement cooperates with the switching arrangement to transfer the data subsets over physically distinct data transfer paths defined between the switching arrangement and the control arrangements. In accordance with one feature, the configuration of the routing arrangement provides for linear expansion whereby to service buses having increased width and/or to service an increased number of buses in a cost effective manner while, in either instance, maintaining high data throughput.
