1. A method of communicating across a distributed multiprocessing system having a first node with a first processor and a first real memory location and a second node with a second processor and a second real memory location, the first and second nodes are connected to a central signal routing hub by first and second communication links, respectively, said method comprising the steps of;

  • indexing the first and second nodes to define different destination addresses for each of the nodes;

    processing information within the first processor of the first node for capturing a signal having an instantaneous value;

    addressing the instantaneous value of the signal using at least one of the destination addresses;

    transmitting the instantaneous value of the signal from the first processor of the first node across the first communication link toward the hub without storing the instantaneous value in the first real memory location of the first node to eliminate any unnecessary duplication of stored data and without the instantaneous value of the signal being requested, thereby defining a sending node;

    receiving the instantaneous value of the signal along with the destination address within the hub;

    identifying the destination address for the transmitted instantaneous value within the hub;

    sending the instantaneous value of the signal without modification, without storing, and without the instantaneous value of the signal being requested from the hub over at least one of the communication links to at least one of the first and second nodes associated with the destination address, thereby defining at least one addressed node; and

    storing the instantaneous value of the signal within the real memory location of the addressed node for subsequent processing or evaluation wherein the step of storing the instantaneous value of the signal is further defined as storing the instantaneous value of the signal only moments before the addressed node requires the instantaneous value for the subsequent processing or evaluation.
