  • Distributed multiple clock system and a method for the synchronization of a distributed multiple system
    Patent number: 5295257
    Abstract: A method for synchronizing a distributed multiple clock system in which the first clock to reach a first predetermined number of counts generates a polling request signal. The remaining clocks compare the content of their counters to determine if they are in synchronization with the clock that generated the polling request signal. Each clock will place itself inactive if it determines it is out of synchronization with the active clocks. The first active clock to reach a second predetermined number of counts will generate a synchronization interrupt signal which resets a counter in each clock to zero. A start subroutine readmits inactive clocks when after a synchronization interrupt signal is generated its counts are within a predetermined readmittance range or its counter counts up to a third predetermined value.
