Abstract:

A storage management apparatus, a storage management method, a processor, and a computer system are disclosed. The storage management apparatus includes: at least one translation look-aside buffer, configured to store a plurality of cache entries, where the plurality of cache entries include a plurality of level 1 cache entries and a plurality of level 2 cache entries; and an address translation unit, coupled to the at least one translation look-aside buffer, and adapted to translate, based on one of the plurality of level 1 cache entries, a virtual address specified by a translation request into a corresponding translated address, or when the translation request does not hit any one of the plurality of level 1 cache entries, translate, based on one of the plurality of level 2 cache entries, a virtual address specified by the translation request into a corresponding translated address. In embodiments of the present disclosure, a hierarchical search is performed among the plurality of cache entries based on the virtual address specified by the translation request. Therefore, time required by searching for a cache entry in an address translation process is reduced, efficiency, frequency, and performance of a processor are improved, and power consumption is reduced.
