Abstract

A data processing system includes a processor, a unit that includes a multi-level cache, a prefetch system and a memory. The data processing system can operate in a first mode and a second mode. The prefetch system can change behavior in response to a desired power consumption policy set by an external agent or automatically via hardware based on on-chip power/performance thresholds.
