Method, system, and apparatus for dynamic thermal management
View Patent ↗A method, apparatus, article of manufacture, and system, the method including, in some embodiments, processing a computational load by a first core of a multi-core processor, and dynamically distributing at least a portion of the computational load to a second core of the multi-core processor to reduce a power density of the multi-core processor for the processing of the computational load.
1. A method comprising:
processing a computational load by a first cluster of at least two associated cores of a multi-core processor; and
throttling a processor pipeline of the multi-core processor to support dynamic power and performance optimizations by dynamically distributing at least a portion of the computational load to a second cluster of at least two associated cores of the multi-core processor to reduce a power density of the multi-core processor for the processing of the computational load in order to trade levels of activity and power of the first cluster of the multi-core processor for increased activity in the second cluster of the multi-core processor.
2. The method of claim 1 , wherein the dynamic distributing occurs at a predetermined frequency.
3. The method of claim 1 , wherein the dynamic distributing occurs at an adaptive frequency.
4. The method of claim 1 , wherein the dynamic distributing is based on a temperature response of the multi-core processor.
5. The method of claim 4 , wherein the temperature response includes at least one of a predetermined operating temperature of the multi-core processor, an adaptive operating temperature of the multi-core processor, and combinations thereof.
6. The method of claim 1 , wherein the dynamic distributing occurs at a frequency greater than a thermal time constant associated with a temperature response of the multi-core processor.
7. The method of claim 1 , wherein a temperature of the second cluster is lower than a temperature of the first cluster.
8. The method of claim 1 , further comprising dynamically distributing at least a portion of the computational load from the second cluster back to the first cluster.
9. The method of claim 1 , wherein the dynamic distributing is based on a relationship between a migration frequency and a temperature response of the multi-core processor.
