Abstract: 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.

Abstract: An electronic device may include a display and display control circuitry. The display may be calibrated to compensate for changes in display temperature. Display calibration information may be obtained during manufacturing and may be stored in the electronic device. The display calibration information may include adjustment factors configured to adjust incoming pixel values to reduce temperature-related color shifts. During operation of the electronic device, display control circuitry may determine the temperature at different locations on the display. The display control circuitry may determine the temperature at a given display pixel using the temperatures at the different locations on the display. The display control circuitry may determine adjustment values based on the temperature at the display pixel. The display control circuitry may apply the adjustment values to incoming pixel values to obtain adapted pixel values, which may in turn be provided to the display pixel.

Abstract: A linked multiple independent control system can include two or more independent controllers configured to cooperatively control operating points of a system. In one particular embodiment, the linked multiple independent control system can control operating temperatures of a computing device. In one embodiment, the independent controllers can operate in parallel to develop control effort signals that are used by the computing device to affect operating parameters of one or more components included in the computing device. In another embodiment, independent controllers can have independent temperature thresholds that can affect control effort signals only from the related controller.

Abstract: 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.
