Abstract
Systems and techniques for selectable slice mapping in shared cache levels are described. In one example, a processor includes a cache system having a shared cache level of a hierarchy of cache levels and slice hashing circuitry associated with the shared cache level. The shared cache level includes multiple slices accessible by threads running on multiple processor cores. The slice hashing circuitry assigns memory addresses used by a particular thread to a subset of the multiple slices closest to the processor core on which the thread runs. The assignment of the slice subset is based on the latency requirements or the data usage of the thread in at least one implementation. The described techniques improve tail latencies for multiple core systems and alleviate the need for additional interconnections for shared cache levels.
