A hierarchial selection hardware synchronization arbitration technique. A plurality of redundant computers each include a sync master counter (38), which is set to reflect the hierarchial selection of each computer. The sync master counter will be inhibited if a sync master signal (60) is present when the computer is activated or if a sync activity signal is present from a higher ranking computer. The computers each have a physical ranking (22, 24, 26, 28) to achieve the hierarchial selection and otherwise can be identical. If the sync master computer generates a fault signal or a fault is detected, then the hierarchial selection of the remaining computers is again commenced. |
