Abstract
According to the methods and apparatus taught herein, processor caching policies are determined using cache policy information associated with a target memory device accessed during a memory operation. According to one embodiment of a processor, the processor comprises at least one cache and a memory management unit. The at least one cache is configured to store information local to the processor. The memory management unit is configured to set one or more cache policies for the at least one cache. The memory management unit sets the one or more cache policies based on cache policy information associated with one or more target memory devices configured to store information used by the processor.
Claims20
A method of determining cache policies, comprising:
- receiving cache policy information associated with one or more target memory devices configured to store information used by a processor;
- and
- setting one or more cache policies based on the cache policy information.
A processor, comprising:
- at least one cache configured to store information local to the processor;
- and
- a memory management unit configured to set one or more cache policies for the at least one cache based on cache policy information associated with one or more target memory devices configured to store information used by the processor.
A system, comprising:
- a processor having at least one cache configured to store information local to the processor;
- one or more target memory devices coupled to the processor and configured to store information used by the processor;
- and
- a memory management unit included in the processor and configured to set one or more cache policies for the at least one cache based on cache policy information associated with the one or more target memory devices.
