Abstract:
A method for automatically transitioning a processor to another performance level in a demang-based system. The invention provides for the automatic adjustment of processor frequency while preserving system responsiveness. The performance-level policy algorithm of the present invention detects increased processor utilization quickly enough that tranistion to a higher performance level is comparable to maximum system performance. The performance-level is comparable to maximum system performance. The performance-level policy algorithm of an embodiment of the present invention delays processor transition to a lower performance level so that quick reversals in demand do not precipitate unnecessary transitioning.
Abstract:
Various embodiments are generally directed to an apparatus, method and other techniques for detecting active and semi-active workloads during execution on a platform processing device and enabling a duty cycle process to reduce thermal output and power consumption, and align unaligned activity. In various embodiments, the duty cycle processing may be enabled during an active workload when thermal output or power consumption is above a thermal threshold or power consumption threshold that is below an efficient operating point for the platform processing device. The duty cycle processing may also be enabled during semi-active workloads when the workload causes the platform processing device to be underutilized and unaligned. The duty cycle processing may comprise enabling a forced idle period for the platform processing device. Other embodiments are described and claimed.
Abstract:
A method for managing thermal condition of a thermal zone that includes multiple thermally controllable components include determining thermal relationship between the components and reducing temperature of a first component by reducing thermal dissipation of a second component.
Abstract:
The present invention relates to a platform power management scheme. In some embodiments, a platform provides a relative performance scale using one or more parameters to be requested by an OSPM system.
Abstract:
A technique to change a thermal design power (TDP) value. In one embodiment, one or more environmental or user-driven changes may cause a processor's TDP value to be changed. Furthermore, in some embodiments a change in TDP may alter a turbo mode target frequency.
