Abstract

PURPOSE: To facilitate an eacy search for the input/output error concerning the peripheral unit by memorizing the input/output order along with the transmission time interval of the order and then reproducing the order with its time interval.
CONSTITUTION: When the software order to release the stuck mode is given at the moment when some abnormal software is detected for the peripheral unit, stuck mode FF is reset. And the input order groups shown at stuck oldest address pointer 53 and stuck latest address pointer 54 are obtained within error searching special region 57 of main memory 5. With application of the software order for start of the reproduction mode, the execution is started from the oldest input/output order which is stored in region 57. A comparison is given between the contents of time counter 1 and the time counting part of the delay order, and thus the time interval can be reproduced directly in the stuck mode.
