Abstract: A computing system with multiple processor cores manages power and performance by dynamic frequency scaling. The system detects a condition when a total number of active processor cores within one or more clusters is less than a predetermined number, and an operating frequency of the active processor cores has risen to a specified highest frequency. The system also obtains ambient temperature measurement of the one or more clusters. Upon detecting the condition, the system increases the operating frequency above the specified highest frequency based on the ambient temperature measurement while maintaining a same level of supply voltage to the active processor cores.

Abstract: A computing system includes a multi-core processor and a core controller. The core controller is for: monitoring utilization of the multi-core processor; calculating a target performance index according to the utilization of the multi-core processor, a target utilization and a first performance index, wherein the first performance index is associated with a first entry of a dynamic voltage frequency scaling (DVFS) table that corresponds to a current setting for the multi-core processor; and selecting a second entry of the DVFS table that corresponds to a target-setting according to the target performance index and a second performance index that is associated with the second entry. The target-setting is used to configure the multi-core processor.
