DIRECTED EVENT SIGNALING FOR MULTIPROCESSOR SYSTEMS |
摘要 |
Multi-processor computing device methods manage resource accesses by a signaling event manager signaling processor elements requesting access to a resource to wake up to access the resource when the resource is available or wait for an event when the resource is busy. Processor elements may enter a sleep state while awaiting access to the requested resource. When multiple elements are waiting for the resource, the processor element with a highest assigned priority is signaled to wake up when the resource is available without waking other elements. Priorities may be assigned to processor elements waiting for the resource based on a heuristic or parameter that may depend on a state of the computing device or the processor elements. A sleep duration may be estimated for a processor element waiting for a resource and the processor element may be removed from a scheduling queue or assigned another thread during the sleep duration. |
