Abstract

PURPOSE: To obtain the useful information for analysis of failure of processor, by detectng the pause signal output at the pause of information processor, suppressing the write-in of memory unit after a given time, and restarting the write-in to the memory unit at the absence of pause signal.
CONSTITUTION: The diagnosed information 1 given from the logical unit to be diagnosed is stored in the data register 2, and the information 1 is stored to the memory unit 3. The write-in address of data to this memory unit 3 is selected with the output of the address decoder 4 decoding the output of the address counter 5. Further, the write-in control circuit 6 is connected to the input of the counter 5, and the pause signal from the information processor, failure detection signal and write-in pulse are input to the input of the control circuit 6, +1 count is made every given time only when the pause signal is 1, and after a given time when the value reaches a given value, the write-in permissible signal and the delivery of +1 signal to the counter 5 are stopped, allowing to restart the write-in when the pause signal is absent.
