<P>PROBLEM TO BE SOLVED: To enable an information processor to change operation environments such as operation voltage, a clock frequency, and the like by itself when executing a diagnostic test due to occurrence of failure. <P>SOLUTION: In a failure management system managing failure in an interface 202, an information processor 201 includes: interface control means 203 for performing control including execution of a diagnostic test for the interface 202; failure management control means 204 for, when a failure occurs, giving notification of the diagnostic test execution and instructions to execute the diagnostic test; change instruction means 205 for, in response to the notification of the diagnostic test execution, giving instructions to change operation environments for executing the diagnostic test; operation environment selection means 206 for, in response to the change instruction, selecting set values for operation power supply voltage and an operation frequency for executing the diagnostic test and giving notification of the selected set values; power supply control means 207 for, in response to the notification of the set value, setting the operation power supply voltage for the set value; and CLK control means 208 for, in response to the notification of the set value, setting the operation frequency for the set value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
