发明名称 ALLOCATING CACHE FOR USE AS A DEDICATED LOCAL STORAGE
摘要 A method and apparatus dynamically allocates and deallocates a portion of a cache for use as a dedicated local storage. Cache lines may be dynamically allocated and deallocated for inclusion in the dedicated local storage. Cache entries that are included in the dedicated local storage may not be evicted or invalidated. Additionally, coherence is not maintained between the cache entries that are included in the dedicated local storage and the backing memory. A load instruction may be configured to allocate, e.g., lock, a portion of the data cache for inclusion in the dedicated local storage and load data into the dedicated local storage. A load instruction may be configured to read data from the dedicated local storage and to deallocate, e.g., unlock, a portion of the data cache that was included in the dedicated local storage.
