Abstract: Techniques and mechanisms for providing a power state wherein a temperature-based voltage regulation is disabled. In an embodiment, a load circuit receives one or more clock signals, and one or more supply voltages. Power management logic facilitates either one of a first power state and a second power state, each for providing power to the load circuit. The first power state enables each clock signal provided to the load circuitry, and further comprises an enabled state of a functionality to perform inverse temperature dependency voltage regulation. The second power state disables each clock signal provided to the load circuitry, and further comprises a disabled state of the functionality. In another embodiment, during the second power state, each voltage supply provided to the load circuit is regulated in a respective voltage range which enables at least some state of the load circuit to be maintained.

Abstract: In an embodiment, a processor includes a core domain with a plurality of cores and a power controller having a first logic to receive a first request to increase an operating voltage of a first core of the core domain to a second voltage, to instruct a voltage regulator to increase the operating voltage to an interim voltage, and to thereafter instruct the voltage regulator to increase the operating voltage to the second voltage. Other embodiments are described and claimed.

Abstract: Presented are temperature-monitoring supply voltage compensation techniques. Some techniques allow for a supply voltage to be monitored and compensated during a reduced power state, even when a control unit circuit that controls the supply voltage is in the reduced power state.

Abstract: In an embodiment, a processor includes a master counter to store a time stamp count for the processor, and multiple cores each including a core counter to store core time stamp counts. The processor also includes synchronization logic to, in response to a de-synchronization event in a core: obtain a value of the master counter; initiate a first core counter using the value of the master counter, where the first core counter is included in the first core; compare a synchronization digit of the first core counter to a synchronization signal indicating a value of a synchronization digit of the master counter; and in response to a determination that the synchronization digit does not match the synchronization signal, adjust a first subset of digits of the first core counter based on a latency value of the synchronization signal.
