PURPOSE: To provide a backup equipment sufficiently suitable for the purpose of test and enough in arrangement by designing this equipment for communication between a 2nd processor and a memory circuit, among a 1st processor, memory circuit and peripheral circuit or between the 2nd processor and the peripheral circuit. CONSTITUTION: The system (PC) is composed of a processor circuit (PC card) 1 and a 2nd processor circuit (PC processor) 2, and the processor circuit 1 is composed of a memory (RAM) 3 and a switching member 4, the respective processor circuits consist of one memory circuit, and further, the processor circuit 1 is composed of a control circuit 5, 1st processor 6 and peripheral circuit 7. Then, this system is designed for communication between the 2nd processor 2 and the memory circuit on one hand and for direct communication among the 1st processor 6, memory circuit and peripheral circuit 7 on the other hand in an intelligent mode and designed for direct communication between the 2nd processor 2 and the peripheral circuit 7 belonging to the 1st processor 6 in a dumb mode. |
