Address translation circuitry responsive to receipt of a first address to perform an address translation between the first address and a second address by performing a predetermined maximum number of sequential lookups , in a plurality of page table levels, wherein the address translation circuitry is configured to: support regular page table levels comprising 2 N entries and large page table levels comprising 2 N*M entries, wherein each sequential lookup in a regular page table level is deemed to be a single level lookup of the predetermined maximum number of sequential lookups and each sequential lookup in a large page table level is deemed to be M level lookups of the predetermined maximum number of sequential lookups; and characterized by performing an intermediate lookup to: retrieve, from a current intermediate page table level of the plurality of page table levels, information indicative of a sequentially next lookup address of a sequentially next page table level and page table level size information indicative of a size of the sequentially next page table level; and when the page table level size information indicates that the sequentially next lookup corresponds to one of the large page table levels and that performing the sequentially next lookup would exceed the predetermined maximum number of sequential lookups, suppress subsequent lookups of the predetermined maximum number of sequential lookups and generate the second address based on the information indicative of the sequentially next lookup address. support regular page table levels comprising 2 N entries and large page table levels comprising 2 N*M entries, wherein each sequential lookup in a regular page table level is deemed to be a single level lookup of the predetermined maximum number of sequential lookups and each sequential lookup in a large page table level is deemed to be M level lookups of the predetermined maximum number of sequential lookups; and characterized by performing an intermediate lookup to: retrieve, from a current intermediate page table level of the plurality of page table levels, information indicative of a sequentially next lookup address of a sequentially next page table level and page table level size information indicative of a size of the sequentially next page table level; and when the page table level size information indicates that the sequentially next lookup corresponds to one of the large page table levels and that performing the sequentially next lookup would exceed the predetermined maximum number of sequential lookups, suppress subsequent lookups of the predetermined maximum number of sequential lookups and generate the second address based on the information indicative of the sequentially next lookup address. retrieve, from a current intermediate page table level of the plurality of page table levels, information indicative of a sequentially next lookup address of a sequentially next page table level and page table level size information indicative of a size of the sequentially next page table level; and when the page table level size information indicates that the sequentially next lookup corresponds to one of the large page table levels and that performing the sequentially next lookup would exceed the predetermined maximum number of sequential lookups, suppress subsequent lookups of the predetermined maximum number of sequential lookups and generate the second address based on the information indicative of the sequentially next lookup address. <EOS>
