    摘要: A cache memory system including a processing unit and a cache memory which is connected to the processing unit, wherein when a store instruction of storing write data into a certain address is executed, the cache memory system executes selectively one of, a first operation mode of allocating an area of the address to the cache memory in response to a generation of a cache miss due to an access to the address, copying data of the address of the main memory unit to the cache memory and then rewriting the copied data on the cache memory using the write data, and a second operation mode in response to a generation of a cache miss due to the access to the address and storing the write data to the cache memory without copying data of the address of the main memory unit to the allocated area on the cache memory.

    摘要: A memory device that can handle various transmission-source devices and transmission-destination devices without modifying the hardware configuration. The memory device is used to transmit and receive data, and includes a data buffer for storing data output from a data-transmission source and outputting the data to a data-transmission destination serving as the data output destination; a transmission-source address converter for performing arrangement processing on the data output from the data-transmission source when the data-transmission source is a device that passively outputs data; and a transmission-destination address converter for performing arrangement processing on the data to be input to the data-transmission destination when the data-transmission destination is a device to which data is passively input.

    摘要: A cache control method controls data sharing conditions in a processor system having multi-level caches that are in an inclusion relationship. The cache control method indexes an upper level cache by a real address and indexes a lower level cache by a virtual address, and prevents a real address that is referred by a plurality of different virtual addresses from being registered a plurality of times within the same cache. A plurality of virtual addresses are registrable within the upper level cache, so as to relax the data sharing conditions.
