Abstract: Systems and methods relate to performing address translations in a multithreaded memory management unit (MMU). Two or more address translation requests can be received by the multithreaded MMU and processed in parallel to retrieve address translations to addresses of a system memory. If the address translations are present in a translation cache of the multithreaded MMU, the address translations can be received from the translation cache and scheduled for access of the system memory using the translated addresses. If there is a miss in the translation cache, two or more address translation requests can be scheduled in two or more translation table walks in parallel.

Abstract: A comparand that includes a virtual address is received. Upon determining a match of the comparand to a burst entry tag, a candidate matching translation data unit is selected. The selecting is from a plurality of translation data units associated with the burst entry tag, and is based at least in part on at least one bit of the virtual address. Content of the candidate matching translation data unit is compared to at least a portion of the comparand. Upon a match, a hit is generated.
