Global memory in the Pave Pace architecture

The Boeing Company is involved in independent research and development activity targeted at studying the partitioning and system control protocols of the Pave Pace architecture. One aspect of the system being investigated is the use of data coupling, involving the implementation of a globally accessible memory called the system virtual memory (SVM) for each computational bus in the system. The use of this SVM would have a dramatic impact on system control protocols, fault tolerance, and software partitioning in the resulting system design. The SVM described is a version formalized from the Air-to-Air Attack Management contract. Specific topics include a conception description of the SVM; a summary of its operation and intended use; and its impact on system control protocols, fault tolerance and failure recovery, and software partitioning.<>
