<P>PROBLEM TO BE SOLVED: To normally conduct information evacuation processing, even when a main control part is brought into a state not operable normally. <P>SOLUTION: A main CPU 212 controls the whole operation of electronic equipment. Information used when the main CPU 212 controls the operation is stored in a system memory 222. A boot memory 224 is prepared for information evacuation, separately from the system memory 222. An information evacuation control part 260 is provided as a functional part for the information evacuation processing, separately from the main CPU 212. A sub-monitoring part 264 monitors the normality and abnormality in an operation of the main CPU 212, and an information evacuation processing part 266 releases control rights of a system memory bus 252 and the first subdata bus 254 to the main CPU 212, when the sub-monitoring part 264 detects the abnormal operation in the main CPU 212, controls directly an information transfer storage part 286, and evacuates information in an evacuation data area 222a of the system memory 222 to the boot memory 224. <P>COPYRIGHT: (C)2011,JPO&INPIT |
