Abstract
A data processing systemincludes a translation lookaside bufferstoring mapping data entriesindicative of virtual-to-physical address mappings for different regions of physical addresses. A hint generatorcoupled to the translation lookaside buffergenerates hint data in dependence upon the storage of mapping data entries within the translation lookaside buffer. The hint generatortracks the loading of mapping data entries and the eviction of mapping data entries from the translation lookaside buffer. The hint data is supplied to a memory controllerwhich controls how data corresponding to respective different regions of physical addresses is stored within a heterogeneous memory system, e.g. the power state of different portions of the memories storing different regions, which type of memory is used to store different regions.
