Cache-Speichervorrichtung zum Speichern von Daten

摘要

The storage device comprises a cache memory which is indexed by the cache index and group information of the virtual address. The real address converted from the virtual address contains first and second group information. If the marking of the cache entry addressed according to the above standard by indexing of the cache memory does not correspond with the real address, indexing is carried out again using the second group information associated with the real address (and using the cache index of the virtual address). If the marking of the cache entry addressed in this way still does not correspond with the real address, a cache miss is signalled.
