Abstract
Address translation circuitry is provided to perform address translation on receipt of a first address to generate a second address. The address translation circuitry comprises a page walk controller configured to perform sequential page table lookups in a plurality of page table levels of a page table hierarchy. Portions of the first address are used to index into sequential page table levels. Cache storage is provided to cache entries comprising translation information retrieved by the sequential page table lookups. An entry in the cache storage further comprises in association with the translation information a re-use indicator indicative of a re-use expectation for subsequent information which is subordinate to the translation information of the entry in the page table hierarchy. The address translation circuitry is configured to modify cache usage for the subsequent information in dependence on the re-use indicator.
