TRACKING MEMORY ACCESSES WHEN INVALIDATING EFFECTIVE ADDRESS TO REAL ADDRESS TRANSLATIONS

摘要

According to embodiments of the present disclosure, a method for invalidating an address translation entry in an effective address to real address translation table (ERAT) for a computer memory can include receiving a first invalidation request. According to some embodiments, the method may also include determining that a first entry in the ERAT corresponds with the first invalidation request, wherein the ERAT has a plurality of entries, each entry in the plurality of entries having an indicator. In particular embodiments, the method may then determine that a first indicator associated with the first entry indicates that the first entry is not being used by any of a plurality of memory access entities (MAE), wherein a first MAE can concurrently use a same entry as a second MAE. The first entry may then be invalidated in response to determining that the first entry is not being used.

1. A method for invalidating an address translation entry in an effective address to real address translation table (ERAT) for a computer memory, the method comprising:
receiving a first invalidation request; determining that a first entry in the ERAT corresponds with the first invalidation request, wherein the ERAT has a plurality of entries, each entry in the plurality of entries having an indicator; determining that a first indicator associated with the first entry indicates that the first entry is not being used by any of a plurality of memory access entities (MAE),
wherein a first MAE can concurrently use a same entry as a second MAE; and invalidating the first entry in response to determining that the first entry is not being used.
