METHOD AND COMPUTER-READABLE MEDIUM FOR DYNAMICALLY MANAGING POWER OF MULTI-CORE PROCESSOR

摘要

A method and a computer-readable medium for dynamically managing power of a multi-core processor of a computing system are provided. The multi-core processor generates a dynamic voltage and frequency scaling (DVFS) table, determines a first index by alternatively selecting either a power budget or a required performance thereof, determines a current thread level parallelism (TLP) of the computing system, selects one of entries according to the current TLP and the first index, and configure first cores and second cores thereof according to a first settings and a second settings of the selected entry.

1. A method for dynamically managing power of a multi-core processor of a computing system, the multi-core processor having a plurality of first cores and a plurality of second cores, and the method comprising:
generating at least a dynamic voltage and frequency scaling (DVFS) table with a plurality of entries, wherein each of the entries comprises a first settings for the first cores and a second settings for the second cores; determining a first index by alternatively selecting either a power budget or a required performance of the multi-core processor; determining a current thread level parallelism (TLP) of the computing system; selecting one of entries according to the current TLP and the first index; and configuring the first cores according to the first settings of the selected entry and configuring the second cores according to the second settings of the selected entry.
