Abstract

PURPOSE:To easily analyze an operation abnormality factor of a system program by transferring automatically data in a memory to an external storage device and recording it, in a reset processing by hardware reset after the whole device becomes inoperable. CONSTITUTION:When an operation of the device becomes impossible and a hardware reset switch is depressed, and reset is instructed, a transfer means saves and transfers control data and work data stored in a storage means (memory 3) to an external storage device prior to reset processing actuation by a reset means (CPU 1), and information for analyzing an inoperable factor can be obtained. Also, the transfer means is actuated at the time of instructing a reset processing or not can be designated by a designating means, and in accordance with necessity, the reset processing and the transfer processing can be selected and executed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus for performing various information processing based on a system program, and more particularly to an information processing apparatus capable of analyzing a system program execution error.

[0002]

2. Description of the Related Art As a device of this type, a device having a document processing and editing function represented by a word processor or the like,
There is a device that performs graphic processing such as graphic creation, and there is also a device that has both of these functions, and is configured to start a system program and perform data processing.

Due to the recent increase in the number of functions, the effort for creating the system program, that is, the software development load tends to be heavy.

By the way, the programs such as the above system programs are created to effectively control the hardware, and the work for confirming whether the programs operate normally is synergistically increased with the development of the programs. .

[0005]

However, in the case of an error in which an operation error that occurs during the execution of a program such as a system program affects the system operation,
In other words, when the entire device becomes inoperable due to a system software malfunction, etc., the contents of the memory are normally initialized by the reset process, and the cause of the system program operation abnormality cannot be pursued. There was a problem that it markedly hindered wear development.

The present invention has been made to solve the above-mentioned problems, and in the reset processing by hardware reset after the entire apparatus becomes inoperable, the data in the memory is automatically stored in the external storage device. An object of the present invention is to obtain an information processing device that can easily analyze a cause of an abnormal operation of a system program by transferring and recording it.

[0007]

An information processing apparatus according to the present invention includes processing means for controlling the entire apparatus based on a read program, reset means for initializing the entire apparatus, control data for the processing means, and When the reset processing is instructed by the storage means for storing the work data and / or the reset means, the control data and / or the work data stored in the storage means is transferred to the external storage device prior to the start of the reset processing by the reset means. And a transfer means.

Further, there is provided a designating means for designating whether or not the transfer means is activated when the reset processing is instructed.

[0009]

In the present invention, when the operation of the apparatus is disabled and the resetting is instructed by the resetting means, the transferring means activates the control data and / or the work data stored in the storing means by the resetting means. It is possible to save and transfer the data to an external storage device in advance and obtain information for analyzing the inoperable factor.

Further, it is possible to specify whether or not the transfer means is activated when the reset processing is instructed by the specifying means, and it is possible to select and execute the reset processing and the transfer processing as needed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram for explaining the configuration of an information processing apparatus showing an embodiment of the present invention.

In the figure, 1 is a central processing unit (CPU) that controls the entire apparatus, and 2 is a non-volatile memory in which control programs and data for the CPU 1 such as processing procedures described later in FIG. 4 are stored. ROM, 3 is a memory used as a work area or the like when the CPU 1 executes control,
Reference numeral 4 is a hard disk (HD), and 5 is a floppy disk (FD) constituting an external storage device, which stores created files and the like.

A keyboard 6 is used by the operator to input data, instructions and the like. 7 is a video RAM (VRA
M) and 8 are bitmap CRTs 9 which constitute display means.
Displays the contents of the VRAM 7 on the CRT 8 or
8 is a CRT controller (CRTC) that performs control of No. 8. Reference numeral 10 is a system bus for exchanging data between the above units.

In the information processing apparatus configured as described above, the operation of the apparatus is disabled and the hardware
When the reset switch 21 is pressed and reset is instructed, the transfer means transfers the control data and / or work data stored in the storage means (memory 3) to the external device prior to the reset processing activation by the reset means (CPU 1). It is possible to save and transfer to a storage device and obtain information for analyzing the inoperable factor.

In addition, designation means (data save key 6
1 (see FIG. 3)), it is possible to specify whether or not to activate the transfer means when the reset processing is instructed, and it is possible to select and execute the reset processing and the transfer processing as needed.

FIG. 2 is a schematic diagram showing a memory map of the memory 3 shown in FIG.

In the figure, 31 is a control data area used as control data and work when the CPU 1 is operating according to the control program stored in the ROM 2, and 32 is an application program operating under the control program. Area 33 is an area for the data.

FIG. 3 is a schematic diagram showing a main configuration of the information processing apparatus shown in FIG.

This flowchart is executed before the initialization process of the memory 3 by the operator pressing the hardware reset switch 21 to execute various processes when the system program becomes abnormal. .

First, it is judged whether or not the data save key 61 has been pressed (1). If NO, the processes after step (5) are executed.

On the other hand, if the judgment in step (1) is YES, the initialization processing routine of the floppy disk 5 is executed (2), and it is judged whether or not the floppy disk 5 is set (3). If NO, proceed to step (5), and if YES, control data area 31 in memory 3.
Data is written to the floppy disk 5 (4), the initialization routine of the memory 3 is executed, and then normal processing is executed (5).

The AM7 data may be combined with these data to be saved.

In the above embodiment, the case where the device to be saved is the floppy disk 5 has been described, but the hard disk 4 or the magnetic tape or the magneto-optical disk may be used.

Further, in the above-described embodiment, the case where the data save key 61 is used to specify whether or not to perform the data save has been described, but the same applies to the value of the specific area of the ROM 2 or the memory 3 or the DIP switch.
