PURPOSE:To perform debugging processing only for some of input and output interruptions when the other central processor is unable to operate, by checking whether the other central processor is able to operate or not, by using a program for an operating system test. CONSTITUTION:When a central processor 2-0 performs necessary debugging processing, the execution interruption point of one operation system A is determined and the central processor 2-0 executes the operation system A. When the execution reaches the execution interruption point X, the processing of the central processor 2-0 is branched to the processing of a debugger 5 after the state at the execution interruption point X is saved. Through the processing of the debugger 5, a check on whether the other central processor 2-1 is able to operate or not is made. When not, only specific input and output interruptions are permitted to perform debugging processing. |
