Abstract

PURPOSE:To collect the information produced before a monitor timer works and to avoid the working of a processor for an electronic computer system, by detecting an interruption due to an auxiliary timer by a discriminating circuit. CONSTITUTION:A processor contains an interval timer 4, a monitor timer 6, an auxiliary timer 8 which is set at a desired time within the time rangesset by the timers 4 and 6 respectively, and a discriminating circuit 10 which discriminates the contents of interruption. When the circuit 10 detects an interruption due to the timer 8 with the signal B, the timers 6 and 8 are reset. Then the memory stacking is performed at that moment for the program information. Then a jog abort processing part 12 is started when a stack area is filled. Thus only the faulty jog is aborted, and the working of the processor is not stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information collection method, and in particular, an information collection method currently in use when a processing unit of a computer system goes out of control, a monitoring timer is activated, and a failure occurs in the processing unit.
In the processing device of the Shiko computer system, for some reason, for example, due to an error in programming or a failure of the device, the processing device may not be able to perform the required processing and run out of control. A monitoring timer is provided to detect this clay running. Furthermore, the 10,000 processing units allow interrupt pre-processing to perform multiple processes in parallel in order to increase processing capacity. This W”
The timing of the e-town in the previous work is generally done using an interpa/timer. On the other hand, regarding the interrupt operation, since it is necessary to execute the process continuously in program processing, the interval timer is provided with a flag indicating whether or not an interrupt is allowed. Therefore, if some kind of failure, such as a program error, occurs during the execution of a program to which an interrupt prohibition flag has been attached, it will be directly caught by the interrupt timer and cause the processing device to stop. When the processing equipment is stopped, no status information can be obtained at that time.
There are two drawbacks: it makes it difficult to take measures after a failure occurs, and it is impossible to detect skidding using a program.

The present invention has been made in view of the above drawbacks, and an object of the present invention is to provide an information collection method that collects information immediately before the processing device is stopped when a failure occurs during imprint compensation. If we look at the 0 tree invention, which is a device that does A circuit for identifying the contents is provided in the processing device, and the job-specific circuit detects the interrupt by the auxiliary timer, collects information on the #J song created by the monitoring timer, and aborts only the job in which an abnormality has occurred.
This provides amnesty for not shutting down processing equipment.

Preferred specific examples for carrying out the present invention will be described in detail below with reference to the drawings. @ Figure 1 is a block diagram of the main parts of a conventional processing device, and Figure 2 is a block diagram of nine '41.

Reference numeral 11 indicates an interrupt internal g identification circuit, and 11 indicates a mode switching and fI switching section. Below, Fig. 2 will be explained while comparing Fig. 1 and Fig. 2. The interval timer 4 and the timer 6 of the processing unit 1 are sesorted to, for example, 500X1O" and 2 seconds, respectively, and the attached auxiliary timer 8 is set to 5.
00
No. 4 is input to the AND circuit 7. This has a flag and when interval timer 4 turns "on", the AND
! 17 outputs the separate signal A.

This printing signal A and No. 18 B of the auxiliary timer 8 are OR circuit 9
is input. The auxiliary timer 8 outputs an "on" signal when the working time is reached. Sub 1\ This auxiliary timer 8 and OR circuit 9 were not included in the quantity.

As a result, the output tS C of the OR circuit 9 becomes the imprint signal. The output ID number C is input to the interrupt #lJ unit 2, and on the other hand, the interrupt control unit 2 is provided with an interrupt content identification circuit 10, and the identification circuit 11j determines whether the input signal C is due to the signal A or the signal B. If the signal B is used, a signal is sent to the depack cage switch 54tlJ control section 11 to switch to the depack mode. In the case of the conventional example, there was no circuit 10 for this interrupt content. Interrupt content identification circuit 1
When detecting that 0 is the A signal, that is, the conventional signal, the interrupt control unit 2 changes the Pi program to Pi+1 by the interrupt signal.
#lJ controls the process change 2-1 to the program and the process 2-2 for resetting the monitoring timer, and the timer reset signal resets the monitoring timer 6. One processing change! 2-
The instruction execution unit 3 changes the instruction based on the IK. If there is no interrupt, the instruction execution unit 3 continues to execute the instruction currently being executed. In any case, if the monitoring timer 6 is activated, the output No. 18 E causes the processing device to be stopped. The above is the previous version of the conventional example, and information is not collected until the system is stopped. In the present invention, the auxiliary timer 8 operates following the operation of the inter-timer 4, and the interrupt content-separate circuit 10 detects that the interrupt is caused by the signal B. Moreover, this interrupt resets the auxiliary timer 8 and the monitoring timer 6, and the mode switching control section 11 resumes execution of the commands of the life cycle section 3 after switching to the debug state. And since it is a dapagu-like lren, 1
Executing an instruction or a push instruction causes a debug mode dJ included DBI.

When the interrupt content sorting circuit IO detects the occurrence of a debug code interrupt, it resets the monitoring timer 6 and the auxiliary timer 8, and performs memory stacking of the psw information at that time. Note that when the stack area becomes full thereafter, the jog abort processing section 12 is activated and only the jog in question is aborted.

As is clear from the above explanation, "According to the present invention, an information collection method can be obtained that can collect information especially when a failure occurs when interrupts are disabled. If the present invention is applied to a computer V-stem, it will be extremely advantageous in terms of 14M analysis. There will be many.
