Abstract

PURPOSE:To permit data at the time of the occurrence of a fault to remain in a hing-priority device, by sending a dumping request to the high-priority device on detecting the occurrence of the fault by a low-priority control processor, and by dumping dump data, stored in the low-priority device, to the high-priority device. CONSTITUTION:If a fault occurs in a low-priority device, an error detecting circuit 4 sends a logging stop signal to a micro bus logger 5 to send an interruption signal to a mu-CPU2. The CPU2 stores an RAM8 with a CPU status in the occurrence of the fault and the step of an instruction being executed, and bus data, etc., in the occurrence of the fault are left in the logger 5. Then, the mu-CPU2 sends a dump request to a host CPU7 through a high-priority connection interface 6, and receives a dump instruction to perform dumping to the host CPU7, thereby writing the contents of the RAM8 and ROM10 of the CPU2 during the occurrence of the fault on the disk, etc., of the CPU7.
