  • Computing unit assembly and a method and a system for synchronizing computing units of an aircraft
    Patent number: 11599141
    Abstract: A synchronizing system including a generation unit for generating a synchronizing pulse from data of an independent clock, the synchronizing pulse being generated in a periodic manner, transmission links to transmit the synchronizing pulse to all the computation units, and in each of the computation units, a control element to compare the synchronizing pulse that has been received to a pulse generated by an internal clock of the computation unit and to detect a compliance or a lack of compliance, a scheduler of each of the computation units activating a sequence of partitions when the synchronizing pulse is received, and this only if the control element has detected a compliance. The synchronizing system is configured to synchronize the computation units in a reliable and accurate manner and to increase the operating safety of these computation units.
