Zusammenfassung:A request storing unit in a PF port stores an expanded request. A PF port entry selecting unit controls two pre-fetch requests expanded from the expanded request to consecutively be input to a L2-pipe. When only one of the expanded two pre-fetch requests is aborted, the PF port entry selecting unit further controls the requests such that the aborted pre-fetch request is input to the L2-pipe as the highest priority request. Further, the PF port entry selecting unit receives the number of available resources from a resource managing unit in order to select a pre-fetch request to be input to a pipe inputting unit based on the number of available resources.
