摘要
A processor includes a plurality of executing sections configured to simultaneously execute instructions for a plurality of threads, an instruction issuing section configured to issue instructions to the plurality of executing sections, and an instruction sync monitoring section configured to, when an instruction-synchronizing instruction is issued to one or more of the plurality of executing sections from the instruction issuing section, monitor completion of execution of the instruction-synchronizing instruction for each of the executing sections, to which the instruction-synchronizing instruction has been issued, thus detecting completion of execution of preceding instructions for the thread to which the instruction-synchronizing instruction belongs. After issuing the instruction-synchronizing instruction, the instruction issuing section stops issuance of succeeding instructions for the thread to which the instruction-synchronizing instruction belongs, until the completion of execution of the preceding instructions for the thread to which the instruction-synchronizing instruction belongs is detected by the instruction sync monitoring section.
