  • Multiple computer system with combiner/memory interconnection system employing separate direct access link for transferring information packets
    Patent number: 5363484
    Abstract: A combiner/memory system interconnects a plurality of computer systems using for example the new HIPPI standard link. The combiner system includes it's own internal storage for rapid shared access to all connected computer systems. The combiner/memory system includes a smart switch for reading header information, arbitrating messsages and connecting computers to each other or to the internal shared storage. The system also includes a mechanism for synchronization of cooperating processes.

  • Method and apparatus for diagnosing net interconnect faults using echo pulsed signals
    Patent number: 5278841
    Abstract: System speed boundary tests are made on nets interconnecting field programmable logic without any external testing equipment or special printed circuit board layout for such a test. Only a single net interconnecting all field programmable logic in a ring is employed. The tests are made for opens and shorts and localize faults to a particular net. Nets interconnecting field programmable logic are tested utilizing the information stored in the circuit design file and the reprogrammability of the field programmable logic to construct a circuit that is then implemented in the field programmable logic and tests all interconnecting nets.
