DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS.
And it demonstrates using FIG.

FIG. 2 is a block diagram of a battery-driven information processing apparatus in this embodiment. 1 is CPU, 2 is DRA
Main memory using M, 3 is display controller, 4 is display memory, 5 is liquid crystal display, 6 is ROM, 7 is battery, 8 is memory controller, 9 is power controller, 10 is power switch for resume, 11 is main A power switch, 12 is a keyboard, 13 is a keyboard controller, 14 is an address / data bus, 20 is a backup power supply line, 21 is SRAM, and 22 is an interrupt signal line.

The power controller 9 monitors the state of the resume power switch 10, the state of the battery 7, and the keyboard controller 13. When the resume power switch 10 is pressed by the user,
When it is detected that the battery 7 is exhausted, or when the occurrence of any one of the cases where there is no input from the keyboard 12 for a certain period of time is detected while the power is on, an interrupt signal line is sent to the CPU 1. 22 is used to notify the occurrence of the condition. When detecting the interrupt signal, the CPU 1 executes the interrupt processing program 50 written in the ROM 6 in advance. The processing contents of the interrupt processing program 50 will be described below with reference to the flowchart of FIG. First, save CPU register contents 5
1 to write the contents of the register of the CPU 1 to the main memory 2, then save the peripheral device I / O register contents 5
At 2, the contents of the I / O registers of the peripheral devices including the display controller 3 and the keyboard controller 13 are read and written in the main memory 2. Furthermore, the display memory 4
Display data stored in display memory contents storage 53
To read and write to the main memory 2. In the save work name setting 54, the user inputs the save work name and
The storage work name is written in the main memory 2. FIG. 14 shows an example of a display screen at the time of the input. Also, save work name setting 54
Then, the value indicating that the state has been saved is also written in the resume flag register provided in the power supply controller 9. Next, in the power OFF processing 55, the CPU 1 controls the power controller 9,
The power supply to the devices other than the power supply controller 9 itself, the main memory 2, the SRAM 21, and the memory controller 8 is stopped, and the power is turned off. In this state, D
The memory controller 8 performs only the minimum required refresh operation for storing the stored contents of the main memory 2 configured by the RAM, and the battery 7 is hardly consumed.

FIG. 1 is a diagram showing an example of the stored contents of the main memory in this embodiment. User can run OS and application programs from 000000H to 17FFFF
Perform using region H. Here, H is a suffix indicating a hexadecimal number. The data saved by the interrupt processing program 50 described above is written in the address area from 18000H to 1FFFFFH. In this example, the storage area A from 000000H to 1FFFFFH
In addition to 101, areas 200,000H to 3FFFFFH and 400000H to 5FFFFFH are used as the storage area B102 and the storage area C103, respectively.
An example is shown in which three types of work states can be saved simultaneously. In addition,
The arrangement of addresses and data may be other than that shown in FIG.

When the power supply controller 9 detects that the user has pressed the resume power supply switch 10 again from the power-off state, the power supply controller 9 restarts power supply to all devices. By the above operation, CP
U1 first executes the reset program 60 stored in the ROM 6. The reset program 60 is shown in FIG.
First, in the state saving check 61, as shown in
The value of the resume flag register provided in the power supply controller 9 is read and it is investigated whether or not the state was saved when the power was turned off. As a result of the above investigation, the power supply OF
If the state is not saved when F is executed, the initial setting 63 is executed, and the main memory, peripheral devices, and devices are checked and initialized as in the case of the information processing device without the resume function, and the user The program is waiting to start. On the other hand, as a result of the investigation, if the state was saved when the power was turned off, the save area input 6
In 2, the user inputs the save work name. Then, in the storage area check 64, it is investigated which storage area in FIG. As a result of the examination, when the storage area is other than the storage area A101 from the address 000000H to 1FFFFFFH, the contents of the storage area A101 are replaced in the replacement of the storage area A. For example, when the save work name save area B102 is indicated in the save area check 64, the contents of the addresses 000000H to 1FFFFFH are transferred from the addresses 200000H to 3FFFFFH and the address 2
Address 00 from the contents of 00000H to 3FFFFFH
Copy from 0000H to 1FFFFFH respectively.
As a result of the above investigation, if the storage area is the storage area A101, the replacement 65 with the storage area A is not executed.
In the display memory contents restoration 66, in the storage area A101,
The contents of the display memory are read out and written in the display memory 4.
In the peripheral device I / O register contents restoration 67, the I / O register values of the peripheral devices including the display controller 3 and the keyboard controller 13 in the save area A101 are read out, and the I / O registers of the display controller 3 and the keyboard controller 13 are read out, respectively. Write the value to. Further, in the CPU register contents restoration 68, the register contents of the CPU1 saved in the save area A101 are written in the registers of the CPU1.

As a result of the processing described above, it is possible to reproduce the work state designated by the user among the one or a plurality of work states interrupted by the power OFF due to the interruption in the past. Note that part of the work state storage data may be stored in the SRAM 21 instead of the main memory.

In the above embodiment, the example in which the user can arbitrarily specify the save work name has been shown. However, as the save work name,
The user ID may be used. By using the user ID, it is possible to prevent the work state of another person from being reproduced when the power is turned on, and it is possible to realize a resume function excellent in terms of security. Further, each user may store and reproduce a plurality of work states by combining the user ID and the name arbitrarily designated by the user. In this case, it is realized by saving the user ID together with the work state instead of the save work name, or by saving the work state in the save area corresponding to the user ID. In the latter case, the operation of requesting the user to input the user ID is performed when the power is turned on again. And the user ID
Investigate whether the work status corresponding to the input exists. As a result, when the work state corresponding to the user ID exists, an operation of further requesting the input of the save work name is performed, and the work state is reproduced from the save area designated by the user's selection in the same manner. .. by this,
It is possible to save the work states of a plurality of users at the same time and reproduce the work states of each user without compromising the security when the power is turned on again.

Next, a second embodiment of the present invention will be described with reference to FIGS.
Will be described below. FIG. 4 is a configuration example of the information processing apparatus in this embodiment. This configuration example shows a magnetic disk 1
6a and a disk controller 15 for controlling the magnetic disk 16a, and a backup power supply line 2
0 and the SRAM 21 are removed, which is a difference from the configuration example of the information processing apparatus in the first embodiment shown in FIG. In the present embodiment, the work state saving in the main memory 2 which was performed in the first embodiment is performed on the magnetic disk 16a.

At this time, the contents of the main memory 2 are also saved in the magnetic disk 16a. That is, the data in each storage area of the main memory 2 in the first embodiment is stored in the working state storage file 200 on the magnetic disk 16a in this embodiment.
Store as. FIG. 5 shows the work state save file 2
An example of the format of 00 is shown. The file name of the work state save file 200 is set to the save work name designated by the user or the name including the user ID, so that one or a plurality of work states of a plurality of users can be obtained as in the first embodiment. Can be saved without sacrificing security and usability, and can be reproduced when the power is turned on again. Further, in the present embodiment, the work state is stored in the magnetic disk 16a, which is a storage device that does not require battery backup. Therefore, the battery backup of the main memory 2 is not necessary, and many work states can be stored for a long time. It has a feature that it can be saved.

Next, a third embodiment of the present invention will be described below with reference to FIG. Reference numeral 17a denotes a first information processing apparatus that allows a user to work using application software, 17b denotes a second information processing apparatus having a magnetic disk 16b, and 17c denotes a third information processing apparatus having the same architecture as the first information processing apparatus 17a. Information processing device. The magnetic disk 16b includes network adapters 18a, 18
It is possible to access from the first information processing device 17a and the third information processing device 17c via the networks b and 18c and the network transmission line 19.

In this embodiment, the first information processing device 17a
The work state save file 200 of the
This is different from the work state saving process in the second embodiment in that the information is stored in the information processing device 17b connected by the network instead of the internal storage device. In this example,
Main memory 2 for storing work state in information processing device 17a
The storage device that does not require battery backup function such as the battery backup function or the magnetic disk 16a is not necessarily required. Further, since it is not necessary to turn off the power of the information processing device 17b in conjunction with the information processing device 17a, the information processing device 1 may be used instead of the magnetic disk 16b unless the information processing device 17b is powered off.
The main memory 7b or the like may be used.

In this case, the power source OF of the information processing device 17a is OF
At F, the work state of the information processing device 17a when the power is turned off is transferred to the information processing device 17b connected via the network. In response to this, the information processing device 17b stores and saves in the main memory of the information processing device 17b or the magnetic storage device 16b. As a result, the information processing device 17a
The resume function can be realized without backing up the main memory with the battery. In addition, the work state stored in the information processing device 17b is changed to the information processing device 1
It is also possible to reproduce with 7c. Therefore, the work state can be saved in the information processing device 17a, and the work state can be reproduced in the information processing device 17c.

Next, a fourth embodiment of the present invention will be described below with reference to FIG. In the present embodiment, in order to avoid the problem that the network connection state when the work state is saved cannot be correctly reproduced when the work state is reproduced, the interrupt processing program 50 explained in FIG. 701, 702, 703, 70 as shown in
4, 705 steps were added. Step 701
First checks if it is connected to the network. If not connected to the network, C in step 51
The processing shifts to the PU register content saving, and the working state saving and power-off processing are performed in exactly the same manner as in the first embodiment. On the other hand, if it is being connected to the network, in step 702, the interrupt processing program 50a
It is checked whether or not it is activated by a timer interrupt due to the absence of input from the keyboard 12 for a certain period of time. In the case of a timer interrupt, the following steps are not executed and this interrupt processing program 50a is terminated. If it is not a timer interrupt, the user is informed that the network connection state cannot be reproduced in step 703, and then the user is inquired whether or not to save the work state in step 704. An example of the display screen at this time is shown in FIG. When the user replies that the work state is not saved, the user is further inquired of whether or not the power is turned off in step 705, and when the user replies that the power is turned off, the power off process of step 55 is executed. If the answer is that it is not turned off, the interrupt processing program 50a is terminated. Step 704
If the user answers that the work state is to be saved, steps 51 to 55 are executed, and the work state is saved and the power is turned off in exactly the same manner as in the first embodiment.

As described above, since the work state is not saved by the timer during the network connection, the work state saving operation in which the network connection state cannot be reproduced because the user interrupted the work for a while is automatically performed. Can be prevented. Further, even when the user tries to save the work state manually, there is an effect that the user can perform appropriate processing by notifying the user that the network connection state cannot be reproduced.

Next, a fifth embodiment of the present invention will be described.
FIG. 10 shows an example of the system configuration in this embodiment.
Reference numeral 17a denotes a first information processing apparatus that allows a user to perform work using application software, 17b denotes a second information processing apparatus that includes a magnetic disk 16b and operates as a server, and 17c denotes the same as the first information processing apparatus 17a. A third information processing apparatus having an architecture and 17c is a fourth information processing apparatus having an architecture different from that of the first information processing apparatus 17a. The magnetic disk 16b is transferred from the first information processing device 17a, the third information processing device 17c, and the fourth information processing device 17d via the network adapters 18a, 18b, 18c, 18d and the network transmission line 19. Can be accessed. The hardware configuration of the information processing device in this embodiment is the same as that shown in FIG. 2 in the first embodiment. The operation will be described below in the order of saving and reproducing the work state.

Power supply controller 9 of information processing device 17a
Monitors the state of the resume power switch 10, the state of the battery 7, and the keyboard controller 13. Then, the power is turned on when the resume power switch 10 is pressed by the user, when the battery 7 is exhausted, or when there is no input from the keyboard 12 for a certain period of time.
When the above condition is detected, the occurrence of the above condition is notified to the CPU 1 using the interrupt signal line 22. C
When the PU1 detects the interrupt signal, the PU1 stores the ROM in advance.
The interrupt processing program 50b written in 6 is executed. The processing contents of the interrupt processing program 50b will be described below with reference to the flowchart of FIG. 8 and the memory map of FIG. First, in step 801, the CPU 1 register contents immediately before the interrupt is generated
It is stored in the U register table 1010. As shown in FIG. 10, the CPU register table 1010 has a structure in which a register number, a size indicating the number of bytes of the register, and CPU register data indicating the contents of the register are set as one set, and the set is repeated by the number of the registers. Is becoming C
The PU register table address 1004 contains the CP
The head address of the U register table address 1010 is stored.

Next, in step 802, the I / O register is read out and the I / O register table 1011 and I / O register table address 1005 shown in FIG. 10 are stored in the main memory 2. I / O register table 1011
Has a structure in which an I / O address, a size indicating the number of bytes of the register, and I / O register data indicating the contents of the register are set as one set, and the set is repeated by the number of the registers. I / O register table address 1
005 is the I / O register table address 10
The first address of 11 is stored.

Next, at step 803, the contents of the display memory 4 are read out and stored in the display memory data table 1012 shown in FIG. Further, the display memory table address 1006 is the display memory table address 1
The start address of 012 is stored.

Next, in step 804, the open file information table 1013 is created. The open file is a file being used by the OS due to the operation of the OS itself or a request from application software. There are three types of open file states: read only, write only, and read / write. Here, as shown in FIG. 10, the file name of an open file, the state of the open file, and the number of bytes including the file name and a flag indicating the state are set as a set, and An open file information table 1013 having a structure repeated by the number of times is created. Further, the open file information table address 1007 includes the display memory table address 101
The top address of 3 is stored.

Next, at step 805, the first information processing apparatus 17a on which this program is operating is physically and logically connected to the second information processing apparatus 17b operating as a server via the network. Investigate whether they are doing. As a result of the investigation, if the connection is established, the next step 8
06 and 807 are executed, and if not connected, step 815 is executed. In step 806, the open file information table 101 created in step 804.
3, the opened server file is closed, and in step 807, the logical name in the network of the second information processing device 17b is changed to the connected server name 1
As 014, it is stored in the main memory 2 as shown in FIG. At this time, the connected server name 1014 on the main memory 2
Is stored in the main memory 2 as the connection server name address 1008. On the other hand, in step 815,
In the connection server name address 1008, "0" indicating that the server is not connected is set.

In step 808, the user is inquired whether to save the work state as a file or to save the main memory by backing it up with a battery. If the user answers that the file is to be saved in a file, the user inputs the file name for saving the work state in step 809. FIG. 16 shows an example of the screen display in steps 808 and 809. Next, in step 810, a work state save file 200a having the file name is created. At this time, in addition to the data contents 203 of the main memory 2 shown in FIG.
1. The save date / time 202 is also stored in the work state save file 200a. FIG. 12 shows the structure of the work state storage file 200a. Next, the resume flag register included in the power supply controller 9 is set to a value indicating that the state is not saved when the file is saved (step 811), and the state is saved when the file is not saved in the file. It is set to a value indicating that (step 812). After that, in step 813, logout is performed to disconnect the connection to the network, power is turned off in step 814, and the interrupt processing program 50b for saving the work state is terminated.

Next, the operation for reproducing the working state will be described. When the power controller 9 detects that the user has pressed the resume power switch 10 again in the power-off state, the power controller 9 starts supplying power to all the devices. As a result, the CPU 1
First, the reset program 60 stored in the ROM 6
Execute b. FIG. 9 shows a flowchart of the reset program 60b. The reset program 60b
First, in step 901, the value of the resume flag register of the power supply controller 9 is read out, and it is investigated whether or not the work state is saved in the main memory 2 when the power is turned off. As a result of the examination, if the work state is stored in the main memory 2, the control is copied to step 912, and if not, step 902 is executed. Step 90
In 2, the user is asked whether or not to reproduce the work state from the file. If the user replies that the work state is not to be reproduced from the file, the control is shifted to the initial setting of step 900, the device is initialized, and the OS is started up. .. In step 902, when the user answers that the file is reproduced from the file, the work state saving file 200a to be used is further used.
The user is inquired about the name of the. FIG. 16 shows an example of the display screen at this time. Next step 90
In step 4, the name of the work state save file 200a is analyzed to determine whether it is a file on the information processing device 17b used as a server. As a result of the check, if the file is not on another information processing device 17b, the control is moved to step 908. If the file is on the information processing device 17b, the network adapter 18a is initialized in step 905, the user inputs the user name and password in step 906, and the user name and password are used in step 907. Then, the user logs in to the information processing device 17b to make a logical connection. FIG. 17 shows an example of screen display in step 906. Next, in step 908, referring to the work state save file 200a,
Saved model code 201 stored when saving the above work status
Read out. Next, in step 909, it is investigated whether or not the stored model code 201 matches the model code of the information processing device executing this program. As described above, in the present embodiment, the information processing device 17a and the information processing device 17c have the same architecture and the same model code, but the information processing device 17d has a different architecture and is different from other information processing devices. I have a different model code. Therefore, the work state is saved in the information processing device 17
If the work state is reproduced by the information processing device 17a or the information processing device 17c, the determination in step 909 is “match”, and the determination is made when the work state is reproduced by the information processing device 17d. Becomes "mismatch". If the result of the determination is "mismatch", in step 910 the user is notified that the model is different, and the user is inquired whether or not to use another work state save file 200a. FIG. 18 shows an example of the inquiry screen. Another work state save file 200a
If the user replies that the user has used, the process returns to step 903, and if the user does not use, the process is not reproduced and control is transferred to the initial settings of step 900 to initialize the device and boot the OS. I do. Step 909
If the result of the determination in step 1 is “match”, the main memory content 203 of the work state saving file 200a is read out in step 911 and expanded in the main memory 2. As a result, the contents of the main memory 2 shown in FIG. 11 are reproduced. Next, in step 912, the content of the connection server name address 1008 is checked, and if the content is “0”, it is determined that the network is not connected when the work state is saved, and step 91
Control is transferred to 8. If the content of the connected server name address 1008 is not "0", it is determined that the server is connected to the network, and the network adapter 1 in step 913 is selected.
8a is initialized. Next, in step 914, it is checked whether or not the user name has been input in step 906, and if it has not been input, step 915.
The user enters the user name and password in step 9
At 16, the user is logged in to the information processing device 17b using the user name and the password. Next, in step 917, the open file information table 1013 in the main memory 2 is referred to, and if there is a file on the information processing device 17b used as a server in the table, the open state of the file is reproduced. In step 918,
The last modification date and time of the file registered in the open file information table 1013 is checked and compared with the storage date and time 202 of the work state storage file 200a. If the last modified date and time is later than the saved date and time 202, there is a possibility that the contents of the file have been changed after saving the work state. Therefore, since the file may not be used as it is, a message as shown in FIG. 19 is displayed to alert the user. Next, in step 919, the contents of the display memory data table 1012 are stored in the display memory 4, and in step 920, the I / O register table 10 is stored.
11, the contents of each I / O register are reproduced. Finally, in step 921, the CPU register table 1010
The contents of each register of the CPU 1 are reproduced with reference to. When step 921 is completed, the reproduction of the work state is completed.

There is an effect that can be reproduced. Further, even if the work state is saved while the file on the other information processing device used as the server is open, the open state can be reproduced when the work state is reproduced, so that the work state can be correctly reproduced. There is an effect. Further, when the open state of the file is reproduced, the working state save date and time is compared with the last modified date and time of the file. If the last modified date and time is later, the contents of the file are changed after the working state is saved. Since the fact is notified to the user, there is an effect that the user can take necessary measures for the file. In addition, the model code 201 of the saved information processing device is stored in the work state saving file 200a, and when the work state is reproduced, it is compared with the model code of the information processing device that reproduces the work state. Since the reproduction is not performed, there is an effect that it is possible to prevent a trouble such as a program runaway that occurs when reproduced on a different model. Further, since the user can select whether to save the work state by the battery backup of the main memory 2 or the work state save file 200a, it is sufficient to save whether or not it is connected to the network or to save a set of work states. Main memory 2
There is an effect that an optimal work state saving method can be selected according to the situation such as whether or not to perform high-speed saving and reproduction by battery backup.

A file 04b and a work state save b 505b are stored in the directory of the command 502b. The processing contents of the programs of the work state save a 505a and the work state save b 505b are the same as those of the interrupt program 5 described above.
The processing procedure of 0, 50a, 50b, etc. may be the same. Also,
Work state reproduction a504a, work state reproduction b50
The processing content of the program of 4b may be the same as the processing procedure of the reset programs 60 and 60b described above. When the user wants to save / reproduce the work state, the work state saving / reproduction program corresponding to the type of OS being used is executed as a command. In OSa, an example of a screen for issuing a command for opening the other window and saving the work state while the graph is being created in one window is shown in FIG.
Shown in 1.

According to the present embodiment, the work state saving and reproducing program can be executed as a command program, so that the resume function can be realized even in an information processing apparatus which does not have a power supply mechanism for resume or a ROM program. There is an effect. In addition, you can select the work state saving and reproduction program according to the type of OS.
Even if a plurality of OSs are used, the working state can be saved and reproduced easily.

In the above-described embodiments, the magnetic disk device is used as the storage device which does not require the battery backup, but any optical disk device may be used as long as the battery backup is unnecessary. The display may be a CRT or the like instead of the liquid crystal display 5.
The work state may be saved and reproduced not only when the power is turned off and then on again, but also at any time when the user wants to suspend or resume the work.

Next, an eighth embodiment of the present invention will be described with reference to FIGS. 22 to 27.

FIG. 23 is a block diagram of an information processing apparatus system using an information processing apparatus according to an embodiment of the present invention.
In this information processing apparatus system, the information processing apparatus 17a

7a returns a connection confirmation response frame in response to the connection confirmation request frame to hold the logical connection. Alternatively, the information processing device 17a periodically transmits a connection confirmation notification frame to the information processing device 17b at an appropriate time interval to hold the logical connection. If the connection confirmation response frame is not returned or the connection confirmation notification frame is not transmitted, the information processing device 17b considers that the information processing device 17a is in an abnormal state and establishes a logical connection. It is designed to be released.

FIG. 22 is a block diagram of an information processing device 17a to which the eighth embodiment of the present invention is applied. In the figure, 23 is a power supply control signal line from the network controller 18 to the power supply controller 9. Further, FIG. 24 is a detailed configuration diagram of the power supply controller 9. Reference numeral 91 is a switch unit for turning on / off the power supplied to each unit, 92 is a power switch controller for controlling the switch unit 91, 93 is a status register for notifying the CPU 1 of the state of the power controller 9, and 94 is the CPU 1 A command register for giving an operation instruction to the power supply controller 9, 95
Is a timer used by the power switch controller 92 for the purpose of timing, and 96 is a power supply line for supplying power to each unit. In the information processing apparatus having the above configuration, the resume function according to the present invention operates as follows.

First, FIG. 25 shows a procedure in which the operating information processing apparatus 17a saves the working state at that time and turns off the power.
The sequence diagram will be described.

When the resume power switch 10 is pressed while the information processing device 17a is operating, or the battery 7
When it detects that the voltage has dropped below a certain value or there is no key input to the keyboard 12 for a certain period of time, the power switch controller 92 needs to interrupt the power supply to the CPU 1 through the interrupt signal line 22. An interrupt requesting the start of various processes is generated (step 101). Upon receiving the interrupt, the CPU 1 starts the work state saving process (step 102). As a method of storing the working state, the RAM 2 is constituted by a RAM that can be backed up by the battery 7, and the display memory 4 is stored in the RAM.
Of storing the work status including the contents of the disk, the method of saving the work status as a file in the disk device 16a, the work status as a file in the disk device 16b connected to the information processing device 17b through the network 19.
There is a method to save in. When the saving of the work state is completed, the CPU 1 writes a specific command indicating the completion of the work state saving in the command register 94 to notify the power switch controller 92 of the completion of the work state saving process (step 103). Power switch controller 9
When notified of the completion of the work state saving process, the second operator operates the switch section 91 to operate the network controller 18
The power supply to each part except for is stopped and the network controller 18 is notified that the power is off (step 104). With this notification, the network controller 18 does not notify the CPU 1 immediately after receiving the frame, but first notifies the power supply controller 9. Through the above processing, the information processing device 17a saves the work state and becomes the power-off state.

Next, when the information processing apparatus 17a saves the working state and is in a power-off state, the information processing apparatus 17b
A procedure for responding to the connection confirmation request frame transmitted from the device will be described with reference to the sequence diagram of FIG.

When a connection confirmation request frame is transmitted from the information processing device 17b when the information processing device 17a is in the power-off state, the network controller 18 causes the CPU 1
Hold the frame reception interrupt to the power control signal line 2
A power-on request is issued to the power controller 9 through 3 (step 111). The power switch request in the power controller 9 is received by the power switch controller 92 in the power controller 9, and the status register 93 is set to indicate that the power is turned on to reproduce the working state.
Is operated to supply power to the power supply line 96 (step 112). However, since the power is temporarily turned on again at the request of the network controller 18, the power is not supplied to the display device 5. Powered CP
U1 starts the reset process by the program stored in ROM6. After the power is turned on, the CPU 1 first reads the contents of the status register 93, recognizes that the work state needs to be reproduced, and starts the work state reproduction process (step 113). When the reproduction of the work state is completed, the CPU 1 notifies the power supply controller 9 of the completion of the work state reproduction by writing a specific command in the command register 94, and continues the reproduced process before the power-off (step 114). When the power supply controller 9 is notified of the completion of the work state reproduction processing, the power supply controller 9 also notifies the network controller 18 of the completion and starts the timer 95 (step 115). The network controller 18, which has been notified of the completion of the work state reproduction process, holds the CPU 1
A frame reception interrupt to is issued here (step 116). CPU 1 receiving the frame reception interrupt
Starts protocol processing. CPU in this process
Since the received frame is the connection confirmation request frame from the information processing device 17b, 1 requests the network controller 18 to transmit the connection confirmation response frame (step 117). In response to the frame transmission request, the network controller 18 transmits a connection confirmation response frame to the information processing device 17b (step 118). After that, when the timer 95 started in step 115 times out, it is notified to the power switch controller 92, and an interrupt requesting the CPU 1 to start the processing required for power off is generated through the interrupt signal line 22 (step 119). ). Upon receiving the interrupt, the CPU 1 starts the work state saving process again (step 120). When the work state saving process is completed, the CPU 1 notifies the power supply controller 9 of the work state saving completion by writing a specific command in the command register 94 (step 121). The power switch controller 92 in the power controller 9 receives the notification, operates the switch unit 91 to stop the power supply to each unit, and notifies the network controller 18 that the power is off again (step 122). ).
Through the above processing, the information processing device 17a responds to the connection confirmation request frame sent from the information processing device 17b by temporarily turning on the power again when the frame is received even when the power is off. It is possible to maintain the logical connection with the information processing device 17b.

Finally, the procedure for turning on the power again at the request of the user when the information processing apparatus 17a saves the working state and is in the power-off state will be described with reference to the sequence diagram of FIG.

When the resume power switch 10 is pressed while the power is off, the power switch controller 92
Sets in the status register 93 that the power is turned on to reproduce the working state, and operates the switch unit 91 to start supplying power to the power supply line 96 (step 131). Here, since the power is turned on again at the request of the user, the information processing device 17a including the display device 5 is included.
Supply power to all parts of. Powered C
PU1 starts the reset process by the program stored in ROM6. After the power is turned on, the CPU 1 first reads the contents of the status register 93, recognizes that the work state needs to be reproduced, and starts the work state reproducing process (step 132). When the reproduction of the work state is completed, the CPU 1 notifies the power supply controller 9 of the completion of the reproduction of the work state by writing a specific command in the command register 94, and continues the reproduced process before the power-off (step 133). .. When the power supply controller 9 is notified of the completion of the work state reproduction processing, the power supply controller 9 notifies the network controller 18 of the completion (step 134).
Since the power is turned on again at the request of the user, the timer 95
Does not start. When the network controller 18 receives a subsequent frame by the notification, it immediately sends the CP.
It will notify U1 by interruption. Through the above processing, the user can reproduce the work state when the power is cut off and continue the work.

Next, a ninth embodiment of the present invention will be described with reference to FIGS. 28 and 29.

FIG. 28 is a block diagram of an information processing device 17a according to the ninth embodiment of the present invention. In the figure, 24 is a timer unit for detecting the elapse of a designated time.

Among the operations of the resume function according to the present embodiment, the procedure in which the information processing apparatus 17a in operation saves the working state to be in the power-off state and the procedure in which the power is turned on again at the request of the user is the following. This is the same as the replacement of the network controller 18 in the sequence diagrams of FIGS. 25 and 27 with the timer unit 24. When the timer unit 24 is notified that the power has been cut off, the timer unit 24 immediately notifies the power supply controller 9 without notifying the CPU 1 of the lapse of the designated time, and when the cancellation of the power cut state is notified. Then, again, the CPU 1 is immediately notified of the elapse of the designated time.

Here, the sequence diagram of FIG. 29 shows the procedure in which the information processing apparatus 17a transmits a connection confirmation notification frame to the information processing apparatus 17b when the timer section 24 detects the elapse of the specified time while the power is off. Will be explained.

When the information processing apparatus 17a is in the power-off state and the timer section 24 detects the elapse of the designated time, the timer section 24 issues a power-on request to the power supply controller 9 through the power supply control signal line 23, and sends it to the CPU 1. The time-out interrupt is suspended (step 141). The power-on request is received by the power switch controller 92 in the power controller 9, and the status register 93 is set to indicate that the power-on is required to reproduce the working state, and the switch unit 91 is operated to connect the power supply line 96. Power supply is started (step 142). However, since the power is temporarily turned on again at the request of the timer unit 24, the display device 5 is not supplied with power. The CPU 1, which is supplied with power, starts the reset process by the program stored in the ROM 6. After the power is turned on, the CPU 1 first reads the contents of the status register 93, recognizes that the work state needs to be reproduced, and starts the work state reproduction process (step 143). When the reproduction of the work state is completed, the CPU 1 notifies the power supply controller 9 of the completion of the reproduction of the work state by writing a specific command in the command register 94, and continues the reproduced process before power-off (step 144). When the power supply controller 9 is notified of the completion of the work status reproduction processing, the power supply controller 9 notifies the completion of the work status reproduction processing by the timer unit
Is also notified, and the timer 95 is started (step 14
5). The timer unit 24, which has been notified of the completion of the work state reproduction process, issues a pending timeout interrupt to the CPU 1 here (step 146). The CPU 1, which has received the time-out interrupt, requests the network controller 18 to transmit a connection confirmation notification frame (step 147). In response to the frame transmission request, the network controller 18 transmits a connection confirmation notification frame to the information processing device 17b (step 147). After that, when the timer 95 started in step 145 times out, the power switch controller 92 is notified of this, and the C signal is sent through the interrupt signal line 22.
An interrupt requesting the start of processing necessary for power-off to PU1 is generated (step 148). Upon receiving the interrupt, the CPU 1 starts the work state saving process again (step 149). When the work state saving process is completed, the CPU 1 writes a specific command in the command register 94 to notify the power supply controller 9 of the completion of the work state saving (step 150). The power switch controller 92 in the power controller 9 receives the notification, operates the switch unit 91 to stop the power supply to each unit, and notifies the timer unit 24 that the power is off again (step 151). ). Through the above processing, the information processing device 17a can transmit the connection confirmation notification frame to the information processing device 17b by temporarily turning on the power again by the timer interrupt even when the power is off. It is possible to maintain a logical connection with the information processing device 17b.

Next, a tenth embodiment of the present invention will be described with reference to FIG.

FIG. 30 is a sequence diagram showing the processing of the 10th embodiment of the present invention. In this sequence diagram, in FIG.
When a frame including a message to be displayed to the user is received from the information processing device 17b while the information processing device 17a having the configuration 2 is in the power-off state while maintaining the logical connection with the information processing device 17b. Represents the processing of.

When the network controller 18 receives from the information processing device 17b a frame containing a message to be displayed to the user, the network controller 1
8, the power controller 9, and each unit of the CPU 1 first perform a series of processes from Step 161 to Step 166. These processes are the same as the processes from step 111 to step 116 shown in the sequence diagram of FIG. Upon receiving a frame reception interrupt from the network controller 18, the CPU 1 starts the protocol processing for the frame (step 167). In this processing, when the CPU 1 finds that the frame contains a message to be displayed to the user, it writes a specific command in the command register 94 and notifies the power supply controller 9 that power-off is unnecessary again. (Step 168) Further, the message is displayed on the display device 5 through the display controller 3 (step 16).
9). Upon receiving the notification, the power switch controller 92 in the power controller 9 stops the timer 95 started in step 165, and also starts power supply to the display device 5 which has not been supplied in step 162 so that the switch portion 91 is started. Is operated (step 170). With the above processing, when a message to be displayed to the user is received in a power-off state in which the logical connection with the information processing device 17b is maintained, it is possible to automatically turn on the power and display the message. Become. Although the received message is unconditionally displayed in this embodiment, before the message display in step 169, the user is inquired whether or not to display the message, and the display instruction is given. You may make it display only when it exists. If there is no instruction within a certain period of time, that is, if there is no user in front of the information processing device 17a, no message is displayed, the work state is saved again, and the power controller 9 is instructed to turn off the power. To do so.
