Abstract
Systems and methods for cache replacement are disclosed. Techniques are described that determine a re-reference interval prediction (RRIP) value of respective data blocks in a cache, where an RRIP value represents a likelihood that a respective data block will be re-used within a time interval. Upon an access, by a processor, to a data segment in a memory, if the data segment is not stored in the cache, a data block in the cache to be replaced by the data segment is selected, utilizing a binary tree that tracks recency of data blocks in the cache.
