Abstract

PURPOSE: To facilitate an easy detection for the faulty areas by securing the constant and continuous recording for the signals of the bus in the data processor and thus reading and regenerating the signal recorded at the occurrence time of the fault.
CONSTITUTION: Memories 6 and 7 give sampling in a fixed speed to the address and data signals supplied through buses 2-1 and 2-2 through variation of the writing address, and then give the renewal to the past data to carry out the writing. Now if some fault occurs to the data process system and thus processor 3 detects the error, controller 8 sets memories 6 and 7 to the reading mode. The data read out of memories 6 and 7 are displayed in sequence on display unit 10 to regenerate the state for buses 2-1 and 2-2 at the time point when the error is caused, which can be applied for tracking of the trouble.
