摘要： A thermal manager has a digital filter whose input is to receive raw temperature values from a sensor and whose output is to provide processed or filtered temperature values according to a filter function that correlates temperature at the sensor with temperature at another location in the device. The thermal manager has a look-up table that further correlates temperature at the sensor with temperature at the other location. The look-up table contains a list of processed temperature sensor values, and/or a list of temperatures representing the temperature at the other location, and their respective power consumption change commands. The thermal manager accesses the look-up table using selected, filtered temperature values, to identify their respective power consumption change commands. The latter are then evaluated and may be applied, to mitigate a thermal at the other location. Other embodiments are also described and claimed.

摘要： At least certain embodiments of the disclosures relate to methods, devices, and data processing systems for thermal-based acoustic management. In one embodiment, a computer-implemented method defers one or more background tasks during normal operation of a system if the system has a reduced performance feature that allows reduced or throttled performance in a non-user state. The system enters a low power state (e.g., sleep state) to cool the system after a period of normal operation. The system enters a different low power state (e.g., dark wake state) with a reduced performance and performs at least one of the deferred background tasks while in this low power state without needing a cooling mechanism.

摘要： A computing system has a thermal manager that changes a power consuming activity limit in the device based on an estimate of temperature of a target location in the system. There are several temperature sensors that are not at the target location. An estimator computes the target location temperature estimate using a thermal model and, as input to the thermal model, data from the sensors. The thermal model produces different estimates of the target location temperature at different ambient temperatures but without computing or measuring the ambient temperatures. Other embodiments are also described and claimed.

摘要： Methods and apparatuses are disclosed to estimate temperature at one or more critical points in a data processing system comprising modeling a steady state temperature portion of a thermal model at the one or more critical points using regression analysis; modeling the transient temperature portion of the thermal model at the one or more critical points using a filtering algorithm; and generating a thermal model at the one or more critical points by combining the steady state temperature portion of the thermal model with the transient temperature portion of the thermal model. The thermal model may then be used to estimate an instantaneous temperature at the one or more critical points or to predict a future temperature at the one or more critical points.

摘要： Circuitry and techniques for managing a power supply are disclosed. A processor-controlled switch is employed to control the delivery of power to conductors that provide power to an external electronic device wherein the processor controls the switch opening and the switch opening based not only on contemporaneous parameter measurements but also on state information known to the processor. The management circuit can control the power supply without requiring the use of an additional sense wire between the management circuit and the external electronic device.

摘要： One embodiment of the present invention provides a system that facilitates selectively increasing the operating frequency of an electronic circuit, such as a computer system. The system begins by operating in a low-power state with the frequency and voltage of the electronic circuit set to low levels. Upon recognizing the need for performance beyond the low power level, the electronic circuit enters the first-intermediate power state. In this first-intermediate power state, the frequency and voltage are set to first-intermediate levels. Upon recognizing the need for performance beyond the first-intermediate power state, the electronic circuit enters the maximum-sustainable power state. In this power state, the frequency and voltage are set to maximum sustainable levels. Upon recognizing the need for performance beyond the maximum-sustainable power state, the electronic circuit temporarily enters a boosted power state beyond the maximum-sustainable power state. In this boosted power state, the frequency and voltages are set to levels beyond the maximum sustainable levels.

摘要： Exemplary embodiments of methods and apparatuses to provide a cooling arrangement for a system are described. The system includes a component coupled to a heat sink. A signal associated with a temperature control of the component is asserted. A target temperature of the heat sink is adjusted based on the signal. In one embodiment, a temperature control loop of the heat sink is operated. The temperature of the heat sink may be monitored using one or more sensors placed on the heat sink. An operation of the component, a cooling unit coupled to the heat sink, or both, may be adjusted based on a relationship between the temperature of the heat sink and an adjusted target temperature. Adjusting the target temperature of the heat sink based on the asserted signal increases efficiency of the system while decreasing cooling.
