Abstract

PURPOSE:To improve the interruption processing efficiency by securing at least the double structure or more for all working registers and switching these registers when data attending with the interruption processing are saved and restored. CONSTITUTION:An address register AR31, a temporary register TR32, a pipeline register PR33 and a working register WR34 are switched with each other with input of a register saving instruction signal 30 from an instruction control circuit 2. Then data are saved and at the same time an idle register is prepared for the interruption processing. At the same time, a program counter PC9 interrupts the normal processing with the input of an interruption processing start signal 5 and outputs an interruption processing address 7 to an instruction memory 14 after saving an instruction address 11 into a stack STK10. Then the interruption processing is started. In such a constitution, the interruption processing is possible as long as the timing matching operation is possible even in a working mode of a pipeline. Furthermore the data can be saved automatically and all at once just by switching those registers having at least the double structure or more by the signal 30.
