Abstract

PURPOSE:To eliminate the waiting time for execution of the data processing by storing the time and the date of the final execution of diagnosis and the diagnosis executing interval into a nonvolatile memory and judging before execution of a diagnosing processing whether the time interval between the present time and date and the time and data of the final execution of diagnosis exceeds the diagnosis executing interval or not. CONSTITUTION:When a power supply is applied, a diagnosing process control means 3 fetches the final diagnosis executing date/time t1 out of a nonvolatile memory 1 and the fetches the diagnosis executing interval t2. At the same time, the means 3 refers to a timepiece 2 to fetch the present date/time (t) and then decides whether the time interval between the time (t) and the time t1 exceeds the interval t2 or not. If so, the means 3 starts a diagnosing process means 4 for execution of the diagnosing process. As a result, the waiting time can always be eliminated during execution of the diagnosing process.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a diagnostic processing control method of a data processing device according to an embodiment of the present invention. 2, a diagnostic processing control means 3, a diagnostic processing means 4, an input/output control device 5, and an input/output device 6.

The non-volatile memory 1 can be banked up using a battery or the like, and stores the last diagnosis execution date and time t when the last diagnosis process was executed.
1 and the diagnosis execution interval t!, which is the time interval at which the predetermined diagnosis is executed. and store it.

Clock 2 shows the current date and time t.

When an event that requires a diagnosis to be executed (power-on to the data processing device, hardware recent, etc.) occurs, the diagnostic processing control means 3 stores the final diagnosis execution date and time t1 and the diagnosis execution interval in the non-volatile memory 1. t, and the current date and time t from the clock 2, and the current date and time t and the final diagnosis execution date and time 1. The diagnostic processing control means 3 starts the diagnostic processing means 4 if it is determined that the diagnostic execution interval t has elapsed. When the diagnosis is executed and the diagnosis result notification is received from the diagnosis processing means 4, the current date and time t is set as the last diagnosis execution date and time 1. If the diagnosis result is normal, an initial program (not shown) is loaded and executed from the input/output device 6 to the memory via the input/output control device 5, and control is passed to the initial program. If the diagnosis result is abnormal, the user will be notified to that effect.

Further, when the diagnostic processing control means 3 determines that the diagnostic execution interval t2 has not elapsed, the diagnostic processing control means 3 controls the input/output device 6 via the input/output control device 5 without activating the diagnostic processing means 4.
Loads the initial program into memory, executes it, and passes control to the initial program.

Referring to FIG. 2, the processing in the diagnostic processing control method of the data processing device of this embodiment is performed at the final diagnosis execution date and time t.
