Systems and methods for cache optimization

A method comprising:

• initializing, by a cache controller of a processing circuitry of a computing device, cache memory with allocated cache lines;
• setting an initial aging policy based on age of one or more of the cache lines within the cache memory;
• and
• determining whether a hint or an instruction having attributes to indicate a level of aging has been received, wherein the aging field comprises a multi-bit age field, wherein the hint at an instruction level includes attributes indicating plural age levels.

At least one computer-readable medium having stored thereon instructions which, when executed, cause a computing device to perform operations comprising:

• initializing, by a cache controller of processing circuitry of the computing device, cache memory with allocated cache lines;
• setting an initial aging policy based on age of one or more of the cache lines within the cache memory;
• and
• determining whether a hint or an instruction having attributes to indicate a level of aging has been received, wherein the aging field comprises a multi-bit age field, wherein the hint at an instruction level includes attributes indicating plural age levels.
