摘要： Embodiments of the invention relate to improving exit latency from computing device processor core deep power down. Processor state data may be maintained during deep power down mode by providing a secondary uninterrupted voltage supply to always on keeper circuits that reside within critical state registers of the processor. When these registers receive a control signal indicating that the processor power state is going to be reduced from an active processor power state to a zero processor power state, they write critical state data from the critical state register latches to the keeper circuits that are supplied with the uninterrupted power. Then, when a register receives a control signal indicating that a processor power state of the processor is going to be increased back to an active processor power state, the critical state data stored in the keeper circuits is written back to the critical state register latches.

摘要： Embodiments of the invention relate to energy efficient and conserving thermal throttling of electronic device processors using a zero voltage processor state. For example, a processor die may include a power control unit (PCU), and an execution unit having power gates and a thermal sensor. The PCU is attached to the thermal sensor to determine if a temperature of the execution unit has increased to greater than an upper threshold, such as while the execution unit is processing data in an active processor power state. The PCU is also attached to the power gates so that upon such detection, it can change the active processor power state to a zero processor power state to reduce the temperature of the execution unit. When the sensor detects that the temperature has decreased to less than a lower threshold, the PCU can change the processor power state back to the active state.

摘要： Embodiments of the invention relate to increased energy efficiency and conservation by reducing and increasing an amount of cache available for use by a processor, and an amount of power supplied to the cache and to the processor, based on the amount of cache actually being used by the processor to process data. For example, a power control unit (PCU) may monitor a last level cache (LLC) to identify if the size or amount of the cache being used by a processor to process data and to determine heuristics based on that amount. Based on the monitored amount of cache being used and the heuristics, the PCU causes a corresponding decrease or increase in an amount of the cache available for use by the processor, and a corresponding decrease or increase in an amount of power supplied to the cache and to the processor.

摘要： Some implementations provide techniques and arrangements to migrate threads from a first core of a processor to a second core of the processor. For example, some implementations may identify one or more threads scheduled for execution at a processor. The processor may include a plurality of cores, including a first core having a first characteristic and a second core have a second characteristic that is different than the first characteristic. Execution of the one or more threads by the first core may be initiated. A determination may be made whether to apply a migration policy. In response to determining to apply the migration policy, migration of the one or more threads from the first core to the second core may be initiated.

摘要： With the progress toward multi-core processors, each core is can not readily ascertain the status of the other dies with respect to an idle or active status. A proposal for utilizing an interface to transmit core status among multiple cores in a multi-die microprocessor is discussed. Consequently, this facilitates thermal management by allowing an optimal setting for setting performance and frequency based on utilizing each core status.
