DYNAMIC FREQUENCY SCALING IN MULTI-PROCESSOR SYSTEMS

Title:

DYNAMIC FREQUENCY SCALING IN MULTI-PROCESSOR SYSTEMS

Document Type and Number:

WIPO Patent Application WO/2016/041509

Kind Code:

A1

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.
