Abstract

PURPOSE:To process instructions efficiently, by processing the time lag between actual instruction exeuction and prefetch in two processing levels of preinterruption and current interruption and by executing instructions one by one till current interruption in case of preinterruption. CONSTITUTION:An execution processing device 4 executs an instruction A and accepts a preinterruption signal 21 in the interval of this execution and issues a start-up signal, and prefetch of an instruction which is the next instruction to the instruction A is restarted by a prefetch processing device 3. All bits of the address of the instruction B and those of the address set for address search are compared with each other, and the instruction A is regarded as executed when the signal 1 is outputted. Thus, since all bits of the address of an instruction C coincide with those of the address set for address search, a current interruption signal 22 as the preprocessing of the instruction is given to the execution processing device 4 from the prefetch processor.
