Abstract: The disclosed embodiments provide an apparatus that controls a cooling system for a computer system. During operation, the apparatus monitors a temperature signal from the computer system to determine a trend for the temperature signal. Then, a filter parameter for a trend-based filter is selected based on the trend. Next, the temperature signal is filtered using the trend-based filter to generate a filtered temperature signal which is then passed through a controller to generate a control signal for the cooling system.

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 said another location. The look-up table contains a list of processed temperature sensor values, and/or a list of temperatures representing the temperature at said another 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 said another location. Other embodiments are also described and claimed.

Abstract: Exemplary embodiments of methods and apparatuses to manage a power of a data processing system are described. One or more constraint parameters of a system are monitored. The data processing system is forced into an idle state for a first portion of a time while allowed to operate for a second portion of the time based on the one or more constraint parameters, wherein the system is forced into the idle state in response to comparing a target idle time to an actual idle time. The target idle time of the system is determined, in one embodiment, based on the one or more constraint parameters. The actual idle time of the system may be monitored to take into account interrupts which disrupt an idle time and idle times resulting from no software instructions to execute. The system may be allowed to operate based on comparisons of the target idle time and the actual idle time.
