System and method for contention-based cache performance optimization

摘要

A data processing unit, method, and computer-usable medium for contention-based cache performance optimization. Two or more processing cores are coupled by an interconnect. Coupled to the interconnect is a memory hierarchy that includes a collection of caches. Resource utilization over a time interval is detected over the interconnect. Responsive to detecting a threshold of resource utilization of the interconnect, a functional mode of a cache from the collection of caches is selectively enabled.
