Abstract

PURPOSE:To exactly execute a retry operation, etc., by starting to processing a fault after the processing of a sub-processing device has ended, when the fault has occurred in a main processing device, in an information processing device consisting of the main processing device and the sub-processing device. CONSTITUTION:When a fault has occurred in a scalar processing part 2 of a main processing device, the cause of its fault is held in a fault cause holding circuit 13, and also an instruction processing inhibit instruction is given to an instruction control part 4. As a result, the instructiin control part 4 stops the instruction processing including a vector instruction sent out by a vector processing part 3 of a sub-processing device. On the other hand, the vector processing part 3 advances the processing in accordance with the vector instruction, and when all is completed, a processing completion signal is sent out to the scalar processing part 2. The scalar processing part 2 receives this signal, sends out a fault processing permission signal to a fault processing part, and the fault processing part starts a retry operation, etc.
