A storage management apparatus, a storage management method, a processor, and a computer system are disclosed. The storage management apparatus includes: a translation look-aside buffer configured to store a plurality of cache entries; an address translation unit configured to translate a virtual address specified by a translation request to a corresponding translation address based on one of the plurality of cache entries; and a control unit coupled to at least one translation look-aside buffer and configured to expand an address range mapped to the selected cache entry. According to embodiments of this disclosure, a translatable address range of the translation look-aside buffer can be expanded, a hit rate of the translation look-aside buffer can be increased, and an execution time of address translation can be reduced, thereby improving performance of the processor and the system.
