PURPOSE:To extract easily information out of an information processor in case the injustice is detected with a program, data, etc., by using a presetting means for firmware restart address, etc. CONSTITUTION:When the injustice is detected with a program, data, etc., exceptional processing firmware is started with an interruption to be given to a microprogram. Then a firmware restart address is set at a restart address register 50. While a signal line 103 of a decoding circuit 40 is set at logic 1 when a control memory read register 30 includes a false fault generation instruction code. Thus an OR circuit secured an OR with an original fault display and informs it to a fault processor 100. The processor 100 shunts and stores each information to and in an information processor for each substrate. When this action is over, the fault factor is checked to perform the fault processing. |
