摘要： A high priority path is added to the normal low priority path through a multi-stage switching network. The high priority path is established at the quickest possible speed because the high priority command is stored at the switch stage involved and made on a priority basis as soon as an output port becomes available. In addition, a positive feedback is given to the node establishing the connection immediately upon the making of the connection so that it may proceed at the earliest possible moment. The high priority path is capable of processing multiple high priority pending requests, and resolving the high priority contention using a snapshot register which implements a rotating priority such that no one requesting device can ever be locked out or experience data starvation. A dual priority switching apparatus with input port connections to output port connections uses as asynchronous means to resolve contention under low priority and the absence of blockage conditions, and switches automatically to a priority driven synchronous means of resolving contention. The protocol requires several parallel data lines plus four control lines so that the switching apparatus can be used for networks having a plurality of nodes, each node having a plurality of input and output ports, with a multiplexer control circuit for each output port for connecting any of I inputs to any of Z outputs, where I and Z can assume any unique value greater or equal to two. The switch has a single physical network path element over which either a low priority or high priority path can be established.

摘要： A receiver device is provided with a low latency recovery apparatus for recovering serially transmitted digital data. The receiver device operates asynchronously in respect to a transmitting device. The low latency recovery apparatus synchronizes the receiver device in one clock time to support throughput of high speed transmission messages received from interconnection networks or interface cables. A metastability proof latch is provided. A synchronization method provides individual alignment for each incoming message. There is instantaneous response to back-to-back messages from different sources. Synchronization is accomplished in the receiving device by implementing a clocking system capable of generating N phase-shifted clocks all operating at the same frequency as the incoming data. The N clocks are shifted an approximately equal amount in relation to each other. The data recovery apparatus selects the one of N clocks which is best in synchronization with the incoming serial data and then to receive the message correctly. The apparatus has a two wire interface for serial data and a bracketing control signal. Serial data is synchronized first to the selected clock and then to a local clock. The bracketing control signals when each message recovery is complete and triggers the start of another message recovery in as little as one clock time.

摘要： A method and apparatus for implementing intelligent priority functions at individual switching apparatus devices which comprise switching networks. The intelligent switching functions are capable of operating in real time systems with high efficiency. The switching apparatus has the capability at each stage of the network to make and/or break connections on a priority basis. If a connection is requested at a switch stage and the connection is being used by a lower priority device, the low priority connection is interrupted (broken) and the requested higher priority connection is established. After the high priority connection has completed its usage of the connection, the high priority connection is broken and the lower priority connection is re-established.

摘要： A generic network device includes a serial line switching apparatus for performing either parallel or serial communications amongst multiple nodes over switching networks. An aspect includes the adaptation of standard and proprietary serial interfaces using either optical or electrical transmission media to interface to a parallel switch. The converted serial data is routed to the selected destination through the parallel switch network, where it is received and converted back into a serial optical or electrical interface/protocol. Thus, the combination of the switching adapter and an ALLNODE parallel switching network make it feasible for serial message data to be switched and routed to various destinations. Further flexibility is provided which permits the switching adapter to be personalized to support any one of a number of standard and proprietary serial protocols. A personalization PROM specifies the particular serial protocol that each individual adapter is to support. The parallel switching network becomes a flexible media that interconnects and allows different serial protocols to communicate with each other; i.e., any number of different serial protocols can interface with the same parallel switch network. This allows every node of the parallel system to send and receive messages using its own native protocol. However, a node is not restricted to communicating only with others nodes using the same protocol, but is can communicate with any of the other nodes regardless of the serial protocol they use.

摘要： In a pipelined instruction execution system including a microstore for storing sequences of microinstruction addresses associated with each macroinstruction, a nanostore for randomly storing unique microinstructions, and an execution unit for executing the microinstructions, a no-op/prefetch apparatus, according to the present invention, prevents a microinstruction address, stored in the microstore, from accessing the nanostore and forces a no-op address into the nanostore when the execution unit executes a conditional microbranch instruction. A no-op microinstruction, corresponding to the no-op address, is retrieved from the nanostore and is executed in the execution unit. During the execution of the no-op microinstruction in the execution unit, the no-op/prefetch apparatus permits either the next sequential microinstruction address following the conditional microbranch instruction to access the nanostore or another non-sequential microinstruction address to access the nanostore, the selection of the next sequential microinstruction address or said another non-sequential microinstruction depending upon the outcome of the execution of the conditional microbranch instruction by the execution unit. As a result, when the microstore and the nanostore are utilized, only one cycle of delay, for resolution of the pipeline, will be encountered following the execution of the conditional branch microinstruction by the execution unit. Furthermore, additional real estate is available on the integrated circuit chip on which the instruction execution system is disposed.

摘要： A multi-stage circuit switched network for improving connection establishment using intelligent switching devices. As a transmission makes its way through the network stages, the probability of connecting to a destination increases, i.e., the chance of encountering a blocked device output is decreased. This is opposite of most traditional networks, whose probability for success diminishes with every stage in the connection sequence.

摘要： Disclosed is a new torus switch with low latency performance improves torus network connection time by trying multipaths in one single high speed operation. This multipath approach can be directed at establishing a connection between two specific nodes over various alternate routes simultaneously. If only one route is available, the multipath approach will find that path instantaneously and establish the desired connection with minimal latency. If several links are available, the multipath method establishes the desired connection over only one of the available links and leaves the other options free to be used by other connections. In addition, routing at intermediate torus network stages improves over the wormhole approach.
