PURPOSE:To eliminate the need of providing a circuit for data processor itself by classifying a factor of an error by a fault processor. CONSTITUTION:When an output of an OR circuit 6 is '1', that is, when a report of generation of an error is received, a fault processing part 10 reads out outputs of error display F/Fs 41 - 4m by using a fault information read-out circuit 5, stores them in a fault information storage part 8, and thereafter, classifies a factor of the error, and executes a fault processing of every error classification. That is, AND of fault information of the fault information storage part 8 and the corresponding bits of mask patterns of mask pattern storage parts 91, 92,... 9 is taken by a comparing circuit of the inside, and OR of its result is executed. Accordingly, when in the bits of the mask pattern, an error display corresponding to '1' is '1' even one, the condition is formed. When all are '0', the condition is not formed. In such a way, the factor of the error can be discriminated. |
