    摘要: An inter-nodal communication system employs full duplex transmission links to connect asynchronously operating nodes. Links between nodes are quiesced to a no-current flow state in the absence of message traffic. The system employs a communication protocol that incorporates time-outs which (1) enable a broken link to be detected at the inception of a message and (2) prevent a receiver from listening to a link which has been quiesced by a transmitter at the other end of a link that is shutting-off. All synchronization messages in the inter-nodal communication network are carried by data links and no additional communication wires are required.

    摘要: A switching array as described for connecting ones of a plurality of data sources to ones of a plurality of data sinks. The array includes source data busses which transmit from a connected source, data words, a connection mask and a connection designator. The connection mask has bit positions that map to individual data sinks. A multiplexer/control circuit module is associated with each individual data sink for controlling the interconnection of the data sink to a source data bus. Each multiplexer/control circuit module is connected to each source data bus and is responsive to an active state connection mask bit and a connection designator on a first source data bus, to establish a connection between an associated sink and the first source data bus. This configuration enables the multiplexer/control circuit module to establish a connection without reference to any other multiplexer/control circuit.
