PURPOSE:To facilitate the analysis of a fault factor by securing such a constitution where a control part proceeds to a process carried out by the prescribed firmware with the transmission of a resetting signal and transfers the internal information to a main memory part for initialization. CONSTITUTION:When a CPU 1 detects that the input/output actions of the CPU 1 are impossible to a control part 2, the CPU 1 transmits a resetting signal R. This signal R is received by a jump control circuit 21 of a control part 20 and the circuit 21 shifts forcibly the process to the firmware 200 from the hitherto firmware 100. Then the part 20 transfers the information on the firmware 10 and a local memory 40 to a main memory part 3 based on the routine of the firmware 20. Then the part 2 including the hardware 10, the memory 40, etc., performs its own initializing process. |
