Synchronization in a Multi-Processor Computing System

摘要

In one aspect, a system includes a device controller, processing clusters, and processing elements. The device controller includes a device event status register configured to store bits corresponding to (i) a global event signal provided by an external source and (ii) a device event signal provided by a device event control register. A processing cluster includes a cluster event register configured to store bits corresponding to (i) the global event signal provided by the external source, (ii) the device event signal provided by the device event control register, and (iii) a cluster event signal. A processing element includes an element event register configured to store bits corresponding to (i) the global event signal provided by the external source, (ii) the device event signal provided by the device event control register, (iii) the cluster event signal provided by the cluster event register, and (iv) a processing element event signal.
