Abstract: Providing for address translation in a virtualized system environment is disclosed herein. By way of example, a memory management apparatus is provided that comprises a shared translation look-aside buffer (TLB) that includes a plurality of translation types, each supporting a plurality of page sizes, one or more processors, and a memory management controller configured to work with the one or more processors. The memory management controller includes logic configured for caching virtual address to physical address translations and intermediate physical address to physical address translations in the shared TLB, logic configured to receive a virtual address for translation from a requester, logic configured to conduct a table walk of a translation table in the shared TLB to determine a translated physical address in accordance with the virtual address, and logic configured to transmit the translated physical address to the requester.
