PROBLEM TO BE SOLVED: To prevent deterioration in performance or increase in power consumption by switching threads at an optimum timing or by optimum frequency.;SOLUTION: A pre-fetch buffer bank 101 includes a plurality of buffer entries and stores a plurality of instructions concerning respective threads. The instruction fetched about each thread is transmitted to a multiplexer (mux) 105 via interconnects T0, T1, T2, T3. The multiplexer 105 selects one instruction corresponding to the selected thread, on the basis of a selection line from thread picker logic 110. The thread picker logic may determines which thread is to be selected, i.e., which instruction of the thread is to be performed, on the basis of the expression of the fetched instruction which is to be provided by a thread block indicator 115 and/or a decoded indication or a decoder 120.;COPYRIGHT: (C)2010,JPO&INPIT
