Abstract
Techniques are disclosed relating to cache thrash detection. In some embodiments, cache controller circuitry is configured to monitor and track performance metrics across multiple levels of a cache hierarchy, detect cache thrashing based on one or more performance metrics, and modify a cache insertion policy to mitigate cache thrashing. Disclosed techniques may advantageously detect and reduce or avoid cache thrashing, which may increase processor performance, decrease power consumption for a given workload, or both, relative to traditional techniques.
