Diagnosis method for processor

Abstract

Abstract PURPOSE:To omit preparation of correct answer data for reduction of the load of a working processor and to shorten processor diagnosing time, by executing the same diagnosis processing as a spare processor in parallel with this spare processor via the working processor which performs diagnosis of the spare processor and having collation of diagnosis results between both processors to inform the result of collation to the working processor. CONSTITUTION:Receiving the diagnosis stare 101, a working processor 100 and a spare processor 200 execute the instructed diagnoses in parallel with each other. Based on he results of diagnoses 102 and 202 the collation is given between the diagnosis results 103 and 203 delivered from both processors 100 and 200 respectively without giving any effect to the processing of the processor 100. Then the collation result 302 obtained from the collation 301 is informed to the processor 100. Thus the processor 100 is not required to prepare the correct answer data for inspection of the diagnosis result 203 of the processor 200. Furthermore the collation is carried out independently of the processor 100. Thus the diagnosis processing capacity is improved improved and the processor diagnosing time is shortened.
