Abstract
A data processing systemincludes an address translation cacheto store a plurality of address translation entries. Eviction control circuitryselects a victim entry for eviction from address translation cacheusing an eviction control parameter. The address translation cachecan store multiple different types of entry corresponding to respective different levels of address translation within a multiple-level page table walk. The different types of entry have different eviction control parameters assigned at the time of allocation. Eviction from the address translation cache is dependent upon the entry type, as well as the subsequent accesses to the entry concerned and the other entries within the address translation cache.
