Image filing devices have been put into practical use that store the read images on an optical disk, search for and read out any stored image, and output it in a form that can be viewed by an output device such as a CRT display device or a printer.

This image filing device uses 71-ware (mechanisms) such as a DMAC (direct memory address controller), a timer controller, a magnetic disk device, an optical disk device, a keyboard, and a mouse.

In such a device, the functions of each hardware are checked when the device is started up, and if an error occurs, an error code or the like is displayed.

Therefore, when an error occurs, only the error code is displayed, and the detailed status of the hardware cannot be known.

(Problem to be Solved by the Invention) As mentioned above, this eliminates the drawback that the detailed status of the hardware is not known when an error occurs.
It is an object of the present invention to provide an information processing device that can know the details of hardware when an error occurs, and can investigate the cause and state of a malfunction in the hardware in more detail.

When the above-mentioned instruction means instructs to start a debugger while the means is displaying a code etc. in an abnormal state, the state of each mechanism at the time when the above-mentioned abnormality occurs is displayed on the above-mentioned display means. It consists of a control means for controlling the

(Function) In a device that processes information by operating various mechanisms, the present invention detects whether or not each of the above mechanisms operates normally when the device is started up, and detects abnormalities based on the detection results. If detected, the abnormal state is displayed as a code, and when the debugger is instructed to start while the code of the abnormal state is being displayed, at the time the above abnormality occurs, The status of each mechanism is displayed.

The scanner device 18 is, for example, a two-dimensional scanning device, and is a document (
By scanning the document (document) two-dimensionally with a laser beam, an electrical signal corresponding to the image on the document is obtained.

The optical disk device 22 sequentially stores images read by the scanner device zis on the optical disk 20.

It also searches the optical disc 20 for an image corresponding to specified search information specified using the keyboard 23 or the like.

The keyboard 23 is used to input search information for the table corresponding to the image to be stored on the optical disc 20 and various operation commands such as storage, search, and editing processing.

Further, the keyboard 23 has a function selection key 23a and a question key (? key) 23b. As a result, the hardware is checked by IPL, which will be described later, and when an error is detected and the error code and error address in the ROM 37 are displayed on the CRT display device 24, the function selection key 23a% is pressed.

The CRT display device 24 displays images read by the scanner device 18 and images retrieved from the optical disc 20.

Further, the display window of the CRT display device 24 is a multi-window type display device that can display four images simultaneously using a maximum of four windows (not shown). Editing processes such as enlarging, reducing, rotating, scrolling, etc. are performed on the images displayed in each display window independently.

The printer device 25 prints images read by the scanner device 18 and images retrieved from the optical disk 20 or CRT.
The image displayed on the display device 24 is printed out (

Read/write simulation tests (image data through tests) are now being conducted.

The above read/write simulation test uses the free space of the main memory 38 instead of the optical disk 20, compresses the data in the page memory 40 using the compression/decompression circuit 50, and transfers this compressed data to the buffer memory 40.
The data is written to an empty area of the main memory 38 via 0a.

After that, in the opposite direction to the data flow during compression, that is, the data written to the free area of the main memory 38 is sent to the compression/expansion circuit 50 via the buffer memory 40a, and is expanded using this compression/expansion circuit 50. , writes this expanded data to the page memory 40. Then, a match is checked by comparing this decompressed data with the original data before compression,
The purpose of converting food data into error data is to check whether errors, etc. have occurred.

If this code data error occurs, CPU3
4 is a CRT display device 24 as shown in FIG.
"System error FM (error code)" and ROM3
7 error occurrence address is displayed. In this display state, the function selection keys 32a, ? When activation of the debugger is instructed by successive activation of the key 32b and function selection key 32a, the CPU 34 uses the CRT display device 24 to display the data in the buffer memory 40H, the data in the main memory 38, the port of the DMAC 35, etc. at the time of the error. is displayed. With this display, the operator can check whether there is an error pit in the status register of the compression/expansion circuit 50, whether the data in the buffer memory 40a and the data in the main memory 38 are
The cause of the error is investigated by looking at the DMACB 5 boat to see if there is any evidence that the DMAC 35 has moved.

Next, the operation at startup in such a configuration will be explained with reference to the flowchart shown in FIG.

First, turn on a power switch (not shown). Then, C
As shown in FIG. 2, the PU 34 displays the message "Please wait for a while" on the CRT display device 24, reads the IPL from the ROM 37, and displays the IPL.
Check the hardware accordingly.

That is, IPL checks DMA C35,
TM check, IPL checksum check in ROM 37, optical disk device 22 check, magnetic disk device 27 check, keyboard 23 and mouse 29 check, optical disk 20 read/write simulation test (image data through test), etc. will be held.

For example, discuss read/write simulation tests. That is, the CPU 34 first writes the original data to the page memory 40, compresses the written data using the compression/decompression circuit 50, and stores the compressed data in the main memory 38 via the buffer memory 40a.
Write to the free area of . Thereafter, the CPU 34 sends the data written into the free area of the main memory 38 to the compression/expansion circuit 50 via the buffer memory 40a, in the opposite direction to the flow of data during compression, and uses this compression/expansion circuit 50. The expanded data is written to the page memory 40. Then, the CPU 34 compares the expanded data with the original data before compression to check for a match, and checks to see if a code data error has occurred.

As a result, if a code data error occurs in the read/write simulation test, the CPU
34 is a CRT display device 2 as shown in FIG.
4: "System error FM (error code)" and ROM
37 error occurrence address is displayed. This display allows you to roughly know the hardware in which the problem has occurred.

Here, the operator presses the function selection key 23 on the keyboard 23.
a,? By sequentially pressing the keys 23b1 and the function selection key 23a, activation of the debugger in the ROM 37 is instructed. In response to this instruction, the CPU 34 debugs the ROM 37 using the error code and error occurrence address, and displays the program status at this time on the CRT display device 24 as shown in FIG.

As a result, the data in the buffer memory 40a, the data in the main memory 38, and the data in the DMAC 35 at the time of the above error are saved.
ports, etc. are displayed on the CRT display device 24. This display allows the operator to check whether an error bit is set in the status register of the compression/expansion circuit 50, or whether there is a difference between the data in the buffer memory 40a and the data in the main memory 38, by checking the DMA C35 port.
You can check to see if there is any evidence that C5 has moved and find out the cause of the error.

As mentioned above, when an error code is displayed due to a hardware malfunction when starting up the device, the function selection keys 23a of the keyboard 23, ? Since the debugger is started by sequentially pressing the key 23b1 and the function selection key 23a, it is possible to know the details of the hardware when an error occurs, and to understand the cause and condition of the hardware malfunction in more detail. You can check it out.
