    摘要: A cache memory of the present invention includes a second cache memory that is operated in parallel with a first cache memory, a judgment unit which, when a cache miss occurs in both of the first cache memory and the second cache memory, makes a true or false judgment relating to an attribute of data for which memory access resulted in the cache miss, and a controlling unit which stores memory data in the second cache memory when a judgment of true is made, and stores the memory data in the first cache memory when a judgment of false is made.

    摘要: The cache memory in the present invention includes a prediction unit 39 which predicts, based on the progress of the memory access outputted from the memory, a line address which should be prefetched next. The prediction unit 39 includes: a prefetch unit 414 which prefetches data of the predicted line data, from the memory to the cache memory; and a touch unit 415 which sets the predicted line address to the cache entry, as a tag, and validates the valid flag, without loading data from the memory into the cache memory

    摘要: A cache memory system which readily accepts software control for processing includes: a cache memory provided between a processor and memory; and a TAC (Transfer and Attribute Controller) for controlling the cache memory. The TAC receives a command which indicates a transfer and an attribute operation of cache data and a target for the operation, resulting from the execution of a predetermined instruction by the processor, so as to request the operation indicated by the command against the address to the cache memory.
