PROCESSING UNIT, INFORMATION PROCESSING DEVICE AND METHOD OF CONTROLLING PROCESSING UNIT

A request storing unit (110) in a PF port (100) stores an expanded request. A PF port entry selecting unit (140) controls two pre-fetch requests expanded from the expanded request to consecutively be input to a L2-pipe (23). When only one of the expanded two pre-fetch requests is aborted, the PF port entry selecting unit (140) further controls the requests such that the aborted pre-fetch request is input to the L2-pipe (23) as the highest priority request. Further, the PF port entry selecting unit (140) receives the number of available resources from a resource managing unit (301) in order to select a pre-fetch request to be input to a pipe inputting unit (200) based on the number of available resources.
