Providing content-aware cache replacement and insertion policies in processor-based devices

A processor-based device, comprising:

• means for determining a plurality of content costs for each of a plurality of cached data values in a cache memory device, based on a plurality of bit values of each of the plurality of cached data values;
• means for identifying, based on the plurality of content costs, a cached data value of the plurality of cached data values associated with a lowest content cost as a target cached data value;
• and
• means for evicting the target cached data value from the cache memory device;
• wherein the plurality of content costs each comprises a count of occurrences of a specified bit value among the plurality of bit values of a cached data value of the plurality of cached data values.

A method for providing content-aware cache replacement and insertion policies, the method comprising:

• determining, by a cache controller circuit, a plurality of content costs for each of a plurality of cached data values in a cache memory device, based on a plurality of bit values of each of the plurality of cached data values;
• identifying, by the cache controller circuit based on the plurality of content costs, a cached data value of the plurality of cached data values associated with a lowest content cost as a target cached data value;
• and
• evicting, by the cache controller circuit, the target cached data value from the cache memory device;
• wherein the plurality of content costs each comprises a count of occurrences of a specified bit value among the plurality of bit values of a cached data value of the plurality of cached data values.

A non-transitory computer-readable medium, having stored thereon computer-executable instructions that, when executed, cause a processor to:

• determine a plurality of content costs for each of a plurality of cached data values in a cache memory device, based on a plurality of bit values of each of the plurality of cached data values;
• based on the plurality of content costs, identify a cached data value of the plurality of cached data values associated with a lowest content cost as a target cached data value;
• and
• evict the target cached data value from the cache memory device;
• wherein the plurality of content costs each comprises a count of occurrences of a specified bit value among the plurality of bit values of a cached data value of the plurality of cached data values.
