According to an aspect of the embodiment, when data on a cache RAM is rewritten in a storage processing of one thread, an determination unit searches a fetch port which holds a request of another thread, checks whether a request exists whose processing is completed, whose instruction is a load type instruction, and whose target address corresponds to a target address in a storage processing. When the corresponding request is detected, the determination unit sets a re-execution request flag to all the entries of the fetch port from the next entry of the entry which holds the oldest request to the entry which holds the detected request. When the processing of the oldest request is executed, a re-execution request unit transfers a re-execution request of an instruction to an instruction control unit for the request held in the entry in which the re-execution request flag is set. |
