<p>PROBLEM TO BE SOLVED: To provide an information processor capable of comparatively easily identifying the cause of trouble.SOLUTION: In a first operation mode, a register access history management unit 15 sequentially acquires a setting value of access to a register 21 which has been detected by a register access monitoring unit 14, as a register access history, and changes one or more setting values in the register access history. In a second operation mode, a register access replacement unit 17 sequentially detects access for writing the setting value to the register 21, and when the setting value of the detected access is different from the setting value in the register access history corresponding to the order of the detected access, the register access replacement unit 17 changes the setting value of the detected access to the setting value in the register access history, and provides the access having the changed setting value to a hardware module 11.</p> |
