摘要: Briefly, a processor and a method to calibrate a temperature reading of a digital thermometer. The calibration is done by using a first temperature value measured by an analog temperature sensor located at one point on the processor die and a second temperature value measured by a digital temperature sensor located at a second point of the processor die.

摘要: A method includes measuring a temperature of a device, determining a voltage applied to the device, determining a leakage power for the device in real time based on the measured temperature and determined voltage and estimating an active power for the device. The method also includes adding the determined leakage power and the estimated active power to estimate a total power value associated with the device, and controlling the device based on the total power value.

摘要: In an embodiment, a processor includes multiple cores and a power controller. The power controller may include a hardware duty cycle (HDC) logic to cause at least one logical processor of one of the cores to enter into a forced idle state even though the logical processor has a workload to execute. In addition, the HDC logic may cause the logical processor to exit the forced idle state prior to an end of an idle period if at least one other logical processor is prevented from entry into the forced idle state. Other embodiments are described and claimed.

摘要: A system for measuring and managing thermal operations of a processor core on a semiconductor die using a sensor positioned in a hotspot of the processor core. A measured temperature reading is determined based upon a temperature sensed by the sensor. Interrupt signals and a software readable register indicating temperature information provide feedback about the thermal environment to the processor. Based upon the measured temperature reading, the interrupt signals direct the processor to modify operation.

摘要: For one disclosed embodiment, a plurality of processor cores may be on a semiconductor die. The processor cores may have at least one corresponding temperature sensor. Circuitry on the semiconductor die may generate thermal event indications based on sensed temperatures from multiple temperature sensors of multiple processor cores. A thermal event indication may indicate that a sensed temperature exceeds a temperature point. Central management logic on the semiconductor die may receive thermal event indications based on sensed temperatures from multiple temperature sensors of multiple processor cores. The central management logic may modify operation of one or more of the processor cores in response to a thermal event indication. Other embodiments are also disclosed.

摘要: A processing platform and a method of controlling power consumption of a central processing unit of the processing platform are presented. By operating the method the processing platform is able to set an upper performance state limit and a lower performance state limit. The upper performance state limit is based on a central processing unit activity rate value and the lower performance state limit is based on a minimum require of the operating system to perform operating system tasks. The performance state values are varying within a range of the lower and upper limits according to a power management policy.
