SYSTEMS AND METHODS FOR SYNCHRONIZATION OF MULTIPLE PROCESSORS

Abstract:

Methods and systems for synchronization of multiple processing cores of an electronic control system are disclosed. The electronic control system is configured to monitor and control operation of a multicore architecture employing one or more processing cores to generate a time reference signal and/or to synchronize with the time reference signal. In some examples, the system employs a single master processor to generate the reference synchronization signal (e.g., a master sync signal). In examples, a rising edge of the partition time reference signal is used as the marker of reference time zero (e.g., the start of a new partition frame). If a core is out of sync with the master sync signal, that core adjusts one or more timing characteristics to align the associated signal with the reference signal.
