ABSTRACT:
A synchronizing circuit synchronizes the asynchronous ready signals for two separate microprocessor subsystems that are running synchronously as part of a fault tolerant computer system. Duplicated synchronization circuits, confined in a master-slave arrangement, are utilized with the duplicate microprocessors. Storage and gating circuitry are used to provide the precise timing signals required for such synchronization.
