Abstract
Some implementations disclosed herein provide techniques for caching memory data and for managing cache retention. Different cache retention policies may be applied to different cached data streams such as those of a graphics processing unit. Actual performance of the cache with respect to the data streams may be observed, and the cache retention policies may be varied based on the observed actual performance.
Claims23
A processor, comprising:
- a cache;
- first logic to determine performance of the cache;
- and
- second logic to apply a retention policy to the cache and to vary the retention policy in response to the determined cache performance.
1 more element
A system, comprising:
- a cache having locations to store data in accordance with one or more retention policies;
- first logic to determine performance of at least a subset of the cache locations;
- and
- second logic to vary the one or more retention policies in response to the determined performance.
1 more element
A method, comprising:
- retaining elements of a cache in accordance with a cache retention policy;
- observing performance of the cache;
- and
- varying the cache retention policy in accordance with the observed performance of the cache.
