Abstract
There is provided address translation circuitry and a method for performing address translation. The address translation circuitry is responsive to receipt of a first address and an identifier to perform an address translation from the first address to a second address by performing a translation table walk comprising one or more translation lookups in a plurality of translation tables that are indexed based on a corresponding portion of the first address. The address translation circuitry is further configured to perform a metadata table walk to determine metadata specific to the identifier and associated with the address translation. The metadata table walk comprises one or more metadata lookups in a plurality of metadata lookup tables, each of the one or more metadata lookups corresponds to one of the one or more translation lookups and is indexed based on a same portion of the first address as that translation.
