Abstract: In an embodiment, a processor includes processing cores, and a central control unit to: concurrently execute an outer control loop and an inner control loop, wherein the outer control loop is to monitor the processor as a whole, and wherein the inner control loop is to monitor a first processing core included in the processor; determine, based on the outer control loop, a first control action for the first processing core included in the processor; determine, based on the inner control loop, a second control action for the first processing core included in the processor; based on a comparison of the first control action and the second control action, select one of the first control action and the second control action as a selected control action; and apply the selected control action to the first processing core. Other embodiments are described and claimed.

Abstract: In one embodiment, a processor includes at least one core to execute instructions and a power controller coupled to the at least one core. The power controller may include a first logic to cause the at least one core to exit an idle state and enter into a maximum performance state for a first time duration, thereafter enter into an intermediate power state for a second time duration, and thereafter enter into a sustained performance state. Other embodiments are described and claimed.

Abstract: In one embodiment, a processor includes a plurality of cores, at least two of which may execute redundantly, a configuration register to store a first synchronization domain indicator to indicate that a first core and a second core are associated with a first synchronization domain, and a power controller having a synchronization circuit to cause a dynamic adjustment to a frequency of at least one of the first and second cores to cause these cores to operate at a common frequency, based at least in part on the first synchronization domain indicator. Other embodiments are described and claimed.

Abstract: In one embodiment, a processor includes: at least one core; a stress detector coupled to the at least one core to receive at least one of a voltage and a temperature at which the processor is to operate, calculate an effective stress based at least in part thereon, and maintain an accumulated effective stress; a clock circuit to calculate a lifetime duration of the processor in a platform; a meter to receive the accumulated effective stress, the lifetime duration and a stress model value and generate a control signal based on a comparison of the accumulated effective stress and the stress model value; and a power controller to control at least one parameter of a turbo mode of the processor based at least in part on the control signal. Other embodiments are described and claimed.
