Abstract
PURPOSE: To simplify the investigation of cause when linkage operation among processors is debugged and a fault occurs, by making it possible to stop other random subprocessors at the same time under the stop condition of a random processor.
CONSTITUTION: Subprocessors 1, 2 and 3 operate independently one another at a usual time. Subprocessors 1, 2 and 3, having stop control registers 4, 5 and 6 respectively, are mutually connected by stop signal transfer means 10. Further, respective processors are provided with stop control registers and stop signal generators 7, 8 and 9 which generate a stop condition signal under the condition given by the above-mentioned stop signal transfer means. Now, when subprocessor 1 is to stop, the stop signal of subprocessor 1 is transferred to subprocessors 2 and 3 via stop signal transfer means 10, so that subprocessors 2 and 3 will stop simultaneously with subprocessor 1.
