<p>PROBLEM TO BE SOLVED: To surely judge the mismatching of plural non-volatile storage devices in the case of executing data processing by a central processing unit(CPU) on the basis of a program dividedly stored in plural non-volatile storage devices. SOLUTION: In a data processing system 10 including the CPU 16 and the 1st and 2nd ROMs 22, 24 and allowing the CPU 16 to execute data processing on the basis of the program dividedly stored in the 1st and 2nd ROMs 22, 24, version information is individually stored in the 1st and 2nd ROMs 22, 24 and the program includes a step for judging the consistency of the 1st and 2nd ROMs 22, 24 on the basis of the version information stored in respective ROMs 22, 24.</p> |
