Abstract:
Methods and systems for managing synonyms in VIPT caches are disclosed. A method includes tracking lines of a copied cache using a directory, examining a specified bit of a virtual address that is associated with a load request and determining its status and making an entry in one of a plurality of parts of the directory based on the status of the specified bit of the virtual address that is examined. The method further includes updating one of, and invalidating the other of, a cache line that is associated with the virtual address that is stored in a first index of the copied cache, and a cache line that is associated with a synonym of the virtual address that is stored at a second index of the copied cache, upon receiving a request to update a physical address associated with the virtual address.
