ABSTRACT:
A central processing unit has a plurality of control sections; a device for selectively operating and unoperating the control sections by an external interrruption signal; and a device for processing an interruption sequence with respect to the interruption signal by the operations of the control sections in a state in which the control sections are operated. The control processing unit may be constructed such that the control sections are composed of two control sections and one of the two control sections processes a normal instruction sequence and is unoperated by the interruption signal, and the other of the two control sections is operated at the times of the normal instruction and interruption and processes the interruption sequence in addition to the normal instruction.
