An address processing section allocates addresses of desired data in a main memory, input from a control block, to any of three hit determination sections based on the type of the data. If the hit determination sections determine that the data stored in the allocated addresses does not exist in the corresponding cache memories, request issuing sections issue transfer requests for the data from the main memory to the cache memories, to a request arbitration section. The request arbitration section transmits the transfer requests to the main memory with priority given to data of greater sizes to transfer. The main memory transfers data to the cache memories in accordance with the transfer requests. A data synchronization section reads a plurality of read units of data from a plurality of cache memories, and generates a data stream for output by a stream sending section.
