Embodiments described include systems, apparatuses, and methods using sectored dynamic random access memory (DRAM) cache. An exemplary apparatus may include at least one hardware processor core and a sectored dynamic random access (DRAM) cache coupled to the at least one hardware processor core.

Partner-aware virtual microsectoring for sectored cache architectures

A cache memory eviction method includes maintaining thread-aware cache access data per cache block in a cache memory, wherein the cache access data is indicative of a number of times a cache block is accessed by a first thread, associating a cache block with one of a plurality of bins based on cache access data values of the cache block, and selecting a cache block to evict from a plurality of cache block candidates based, at least in part, upon the bins with which the cache block candidates are associated.

Dead block predictors for cooperative execution in the last level cache

An apparatus and method are described for implementing an exclusive lower level cache (LLC) policy within a computer processor. For example, one embodiment of a computer processor comprises: a mid-level cache circuit (MLC) for storing a first set of cache lines containing instructions and/or data; a lower level cache circuit (LLC) for storing a second set of cache lines of instructions and/or data; and an insertion circuit for implementing a policy for inserting or replacing cache lines within the LLC based on values of use recency and use frequency associated with the lines.
