Description

[0001]
[Industrial application fields]
The present invention relates to an information processing apparatus such as a personal computer, and more particularly to a resume function for reproducing a work state such as when the power is turned off when the power is turned on again. Furthermore, the present invention relates to a resume function in an information processing system in which a plurality of information processing apparatuses are connected via a network.
[0002]
[Prior art]
With recent advances in small packaging technology and low power consumption technology, personal computers, workstations, word processors, etc. (hereinafter referred to as information processing devices) are becoming increasingly smaller, and recently, battery-powered is possible. Notebook-size products are also available. In such a battery-driven information processing apparatus, it is required to manually or automatically turn off the power frequently in order to prevent battery consumption. However, when turning off the power, for example, it is necessary to store user information such as a document being created in a non-volatile storage device. When the power is turned on again, the program and the user information are again stored in the non-volatile memory. It is necessary for the user to call from the storage device. For this reason, frequently turning off the power causes a problem that it is extremely inconvenient for the user.
[0003]
Therefore, in the battery-driven information processing apparatus, the contents of the display memory and the contents of the I / O register of the input / output device are stored in the main memory and the main memory is backed up by the battery before the power is turned off. When the power is turned on again, the contents of the display memory saved in the main memory and the contents of the I / O register of the input / output device are written back to the respective devices, as if the power was turned on. Generally, a resume function for reproducing the state when the power is turned off is provided. Information processing apparatuses having such a resume function are disclosed in, for example, Japanese Patent Laid-Open Nos. 57-17042 and 2-93814.

As described above, the resume function can reproduce the user's work state when the power is turned on again even when the battery is consumed by turning off the power frequently, and it does not cause usability degradation. A device is provided. However, with the resume function of the conventional information processing apparatus, the user cannot perform other work while saving one work state. In addition, when multiple users use the same information processing device, if the operator who has been using previously performed the save using the resume function, when the operator to be used later turns on the power, The operator's working state was reproduced, which was not preferable in terms of security and usability.
[0005]
In addition, since the work state is saved by backing up the main memory with a battery, the work state can be saved only for a limited time determined by the capacity of the battery.

It is to provide an information processing apparatus.
[0015]
[Means for Solving the Problems]
The first object is to provide a plurality of sets of work state storage areas for storing information in the storage device, and the processing device can determine the work state based on the information of one set of work state storage areas designated by the operator among the plurality of sets.

In addition, by continuing to supply power to the network controller or timer even after saving the work state, it is possible to continue processing necessary to maintain the connection state with other information processing devices. Can be reproduced normally.
[0027]
Further, by continuing to energize the network controller even after saving the work state, it is possible to receive a frame including a message and display the message to the user.
[0028]
【Example】
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1, 2, and 3. FIG.
[0029]
FIG. 2 is a configuration diagram of the battery-driven information processing apparatus in the present embodiment. 1 is CPU, 2 is main memory using DRAM, 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 for resume A power switch, 11 is a main 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 an SRAM, and 22 is an interrupt signal line.
[0030]
The power controller 9 monitors the state of the resume power switch 10, the state of the battery 7, and the keyboard controller 13. Then, when the resume power switch 10 is pressed by the user, when it is detected that the battery 7 is exhausted, or when there is no input from the keyboard 12 for a certain period of time, the power is turned on. When it is detected, the CPU 1 is notified of the occurrence of the state using the interrupt signal line 22. When the CPU 1 detects 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, the register contents of the CPU 1 are written into the main memory 2 in the CPU register contents save 51, and then the peripheral device I / O registers including the display controller 3 and the keyboard controller 13 in the peripheral device I / O register contents save 52 Is read and written into the main memory 2. Further, the display data stored in the display memory 4 is read out by the display memory content storage 53 and written into the main memory 2. In the saved work name setting 54, the user inputs the saved work name and writes the saved work name to the main memory 2. A display screen example at the time of the input is shown in FIG. In the save work name setting 54, a value indicating that the state is saved is also written in the resume flag register provided in the power supply controller 9. Next, in the power-off process 55, the CPU 1 controls the power controller 9, whereby the power supply to the power controller 9 itself, the main memory 2, the SRAM 21, and the devices other than the memory controller 8 is stopped. To do. In this state, only the minimum refresh operation necessary to save the storage contents of the main memory 2 composed of DRAM is performed by the memory controller 8, and the battery 7 is hardly consumed.
[0031]
FIG. 1 is a diagram showing an example of the contents stored in the main memory in the present embodiment. The user executes the OS and application programs using the area from 000000H to 17FFFFH. Here, H is a suffix indicating a hexadecimal number. The data saved by the interrupt processing program 50 is written in the address area from 180000H to 1FFFFFH. In this example, the storage area A101 from 000000H to 1FFFFFH, the areas from 200000H to 3FFFFFH, and 400000H to 5FFFFFH are used as the storage area B102 and the storage area C103, respectively, and three types of work states can be stored simultaneously. The arrangement of addresses and data may be other than that shown in FIG.
[0032]
When the power controller 9 detects that the user has pressed the resume power switch 10 again from the power-off state, the power controller 9 resumes power supply to all devices. With the above operation, the CPU 1 first executes the reset program 60 stored in the ROM 6. As shown in FIG. 3, the reset program 60 first reads the value of the resume flag register included in the power supply controller 9 in the state saving check 61 and investigates whether or not the state is saved when the power is turned off. As a result of the investigation, if the state is not saved when the power is turned off, the initial setting 63 is executed, and the main memory, the peripheral device, and the device are checked and the initial setting is performed in the same manner as the information processing device having no resume function. And the program is waiting to be started by the user. On the other hand, as a result of the investigation, if the state is saved when the power is turned off, the save work input name is input by the user in the save area input 62. Then, a storage area check 64 checks which storage area in FIG. As a result of the investigation, when the storage area is other than the storage area A101 from the address 000000H to 1FFFFFFH, the content with the storage area A101 is replaced in the replacement 65 with the storage area A. For example, if the save work name save area B102 is indicated in the save area check 64, the contents of addresses 000000H to 1FFFFFH are copied from addresses 200000H to 3FFFFFH, and the contents of addresses 200000H to 3FFFFFH are copied from addresses 000000H to 1FFFFFH. . As a result of the investigation, when the storage area is the storage area A101, the replacement 65 with the storage area A is not executed. In the display memory content restoration 66, the display memory content in the storage area A 101 is read and written to the display memory 4. In the peripheral device I / O register contents return 67, the I / O register values of the peripheral devices including the display controller 3 and the keyboard controller 13 in the storage area A101 are read, and the I / O registers of the display controller 3 and the keyboard controller 13 are read out. Write the value to. Further, in the CPU register contents return 68, the CPU1 register contents stored in the storage area A101 are written into the CPU1 register.
[0033]
As a result of the processing described above, it is possible to reproduce the work state designated by the user among one or a plurality of work states interrupted in the past by turning off the power due to the interrupt. A part of the work state storage data may be stored in the SRAM 21 instead of the main memory.
[0034]
In the above-described embodiment, an example in which a user can arbitrarily specify a saved work name has been described. However, a user ID may be used as the saved work name. By using the user ID, it is possible to prevent another person's work state from being reproduced when the power is turned on, and to realize a resume function that is excellent in terms of security. Further, each user may store and reproduce a plurality of work states by combining a user ID and a name arbitrarily designated by the user. In this case, it is realized by saving the user ID together with the work status instead of the saved work name, or by saving the work status in a save area corresponding to the user ID. In the latter case, when the power is turned on again, an operation for requesting the user to input a user ID is performed. Then, it is investigated whether or not there is a work state corresponding to the user ID input. As a result, when there is a work state corresponding to the user ID, an operation for requesting the input of the saved work name is further performed, and the work state is reproduced from the save area designated by the user selection in the same manner. . As a result, the work states of a plurality of users can be saved simultaneously, and the work states of each user can be reproduced without sacrificing security when the power is turned on again.
[0035]
Next, a second embodiment of the present invention will be described below with reference to FIGS. FIG. 4 is a configuration example of the information processing apparatus in the present embodiment. This configuration example is provided with a magnetic disk 16a and a disk controller 15 for controlling the magnetic disk 16a, and the backup power supply line 20 and the SRAM 21 are removed. The information processing in the first embodiment shown in FIG. Different from the device configuration example. In the present embodiment, the work state storage in the main memory 2 performed in the first embodiment is performed on the magnetic disk 16a.
[0036]
At this time, the contents of the main memory 2 are also saved to the magnetic disk 16a. That is, the data in each storage area of the main memory 2 in the first embodiment is stored as a work state storage file 200 on the magnetic disk 16a in this embodiment. FIG. 5 shows an example of the format of the work state saving file 200. The file name of the work state saving file 200 is a name including a saved work name designated by the user or a user ID, so that a plurality of work states of one or a plurality of users are the same as in the first embodiment. Can be stored without sacrificing security and usability, and can be reproduced when the power is turned on again. Further, in this embodiment, since the work state is stored in the magnetic disk 16a, which is a storage device that does not require battery backup, the battery backup of the main memory 2 is not necessary, and many work states are stored for a long time. It can be stored.
[0037]
Next, a third embodiment of the present invention will be described below with reference to FIG. 17a is a first information processing apparatus in which a user performs work using application software, 17b is a second information processing apparatus having a magnetic disk 16b, and 17c is a third information processor having the same architecture as the first information processing apparatus 17a. Information processing apparatus. The magnetic disk 16b can be accessed from the first information processing device 17a and the third information processing device 17c via network adapters 18a, 18b, 18c and a network transmission line 19.
[0038]
In the present embodiment, the work state storage file 200 of the first information processing device 17a is stored in the information processing device 17b connected via the network, not in the storage device inside the information processing device 17a. This is a point different from the work state saving process in the embodiment. This embodiment is characterized in that the information processing device 17a does not necessarily require a storage device that does not require battery backup such as the battery backup function of the main memory 2 for storing the work state and the magnetic disk 16a. Further, since it is not necessary to turn off the power supply of the information processing device 17b in conjunction with the information processing device 17a, if the power supply of the information processing device 17b is not turned off, the main memory or the like of the information processing device 17b is used instead of the magnetic disk 16b. It may be used.
[0039]
In this case, when the information processing apparatus 17a is turned off, the work state when the information processing apparatus 17a is turned off is transferred to the information processing apparatus 17b connected via the network. In response to this, the information processing device 17b stores and saves it in the main memory or the magnetic storage device 16b of the information processing device 17b. As a result, the information processing device 17a can realize the resume function without backing up the main memory with the battery. Further, the work state stored in the information processing apparatus 17b can be reproduced by the information processing apparatus 17c. Accordingly, the work state can be saved by the information processing apparatus 17a, and the work state can be reproduced from the information processing apparatus 17c.
[0040]
Next, a fourth embodiment of the present invention will be described below with reference to FIG. In this embodiment, in order to avoid the problem that the network connection state at the time of saving the work state cannot be correctly reproduced when the work state is reproduced, the interrupt processing program 50 described in FIG. Steps 701, 702, 703, 704, and 705 as shown in FIG. In step 701, first, it is checked whether or not connection to the network is in progress. If it is not connected to the network, the processing shifts to CPU register contents saving in step 51, and the working state saving and power-off processing are performed in the same manner as in the first embodiment. On the other hand, if it is connected to the network, in step 702, it is checked whether or not the interrupt processing program 50a has been started by a timer interrupt due to no input from the keyboard 12 for a predetermined time. In the case of a timer interrupt, the following steps are not executed and the interrupt processing program 50a is terminated. If it is not a timer interrupt, in step 703, the user is informed that the network connection state cannot be reproduced, and then in step 704, the user is inquired whether to save the work state. An example of the display screen at this time is shown in FIG. If the user responds that the work state is not stored, the user is further inquired whether or not the power is turned off in step 705, and if the user answers that the power is turned off, the power off process in step 55 is executed. If it is answered that it is not turned off, the interrupt processing program 50a is terminated as it is. If it is determined in step 704 that the user saves the work state, steps 51 to 55 are executed, and the work state is saved and the power is turned off in the same manner as in the first embodiment.
[0041]
As described above, the work state is not saved by the timer while the network is connected, so that the work state saving operation that cannot reproduce the network connection state because the user interrupted the work for a while is prevented from being automatically performed. be able to.
[0042]
Further, even when the user tries to save the work state manually, there is an effect that the user can perform an appropriate process by notifying the user that the network connection state cannot be reproduced.
[0043]
Next, a fifth embodiment of the present invention will be described. FIG. 10 is a configuration example of a system in the present embodiment. 17a is a first information processing apparatus in which a user performs work using application software and the like, 17b is a second information processing apparatus that includes a magnetic disk 16b and operates as a server, and 17c is the same as the first information processing apparatus 17a. A third information processing apparatus 17c having an architecture is a fourth information processing apparatus having an architecture different from that of the first information processing apparatus 17a. The magnetic disk 16b is connected to the first information processing device 17a, the third information processing device 17c, and the fourth information processing device 17d via network adapters 18a, 18b, 18c, and 18d and a network transmission line 19. Can be accessed. Note that the hardware configuration of the information processing apparatus in this embodiment is the same as that shown in FIG. 2 in the first embodiment. Hereinafter, the operation will be described in the order of storage and reproduction of the work state.
[0044]
The power supply controller 9 of the information processing apparatus 17a 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 there is no input from the keyboard 12 for a certain period of time, the power is turned on. When the state is detected, the CPU 1 is notified of the occurrence of the state using the interrupt signal line 22. When the CPU 1 detects the interrupt signal, the CPU 1 executes the interrupt processing program 50b written in advance in the ROM 6. The processing contents of the interrupt processing program 50b will be described below using the flowchart of FIG. 8 and the memory map of FIG. First, in step 801, the register contents of the CPU 1 immediately before the occurrence of the interrupt are stored in the CPU 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. It has become. The CPU register table address 1004 stores the head address of the CPU register table address 1010.
[0045]
Next, in step 802, the I / O register is read, and the I / O register table 1011 and the I / O register table address 1005 shown in FIG. The 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. It has become. In the I / O register table address 1005, the head address of the I / O register table address 1011 is stored.
[0046]
Next, in step 803, the contents of the display memory 4 are read and stored in the display memory data table 1012 shown in FIG. The display memory table address 1006 stores the head address of the display memory table address 1012.
[0047]
Next, in step 804, an open file information table 1013 is created. An open file is a file that is being used by the OS for the operation of the OS itself or by 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 the open file, the status of the open file, and the number of bytes including the file name and the flag indicating the status are set as one set, and An open file information table 1013 having a structure that repeats the number is created. Further, the head address of the display memory table address 1013 is stored in the open file information table address 1007.
[0048]
Next, in step 805, whether the first information processing apparatus 17a in which the program is operating is physically and logically connected to the second information processing apparatus 17b in operation as a server via a network. Investigate. As a result of the investigation, if the connection is established, the following steps 806 and 807 are executed. If the connection is not established, step 815 is executed. In step 806, the open file information table 1013 created in step 804 is referred to, the open server file is closed, and in step 807, the logical name in the network of the second information processing apparatus 17b is connected. The server name 1014 is stored in the main memory 2 as shown in FIG. At this time, the storage address of the connection server name 1014 on the main memory 2 is stored on the main memory 2 as the connection server name address 1008. On the other hand, in step 815, “0” indicating that the server is not connected is set in the connected server name address 1008.
[0049]
In step 808, the user is inquired whether the work state is stored as a file or the main memory is backed up by a battery for storage. If the user answers that the file is stored, in step 809, the user inputs a file name for storing the work state. An example of the screen display in steps 808 and 809 is shown in FIG.
[0050]
Next, in step 810, a work state saving 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. 11, the storage model code 201 and the storage date 202 are also stored in the work state storage file 200a. FIG. 12 shows the configuration 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 stored in a file (step 811), and when not stored in the file, the state is saved. (Step 812). Thereafter, logout is performed at step 813 to disconnect the connection to the network, power supply OFF processing is performed at step 814, and the interrupt processing program 50b for saving the work state is terminated.
[0051]
Next, an operation for reproducing the work state will be described. When the power controller 9 detects that the user has pressed the resume power switch 10 again from the power-off state, the power controller 9 starts supplying power to all devices. Thereby, the CPU 1 first executes the reset program 60b stored in the ROM 6. FIG. 9 shows a flowchart of the reset program 60b. First, in step 901, the reset program 60b reads the value of the resume flag register of the power supply controller 9, and checks whether or not the work state is stored in the main memory 2 when the power is turned off. As a result of the investigation, if the work state is stored in the main memory 2, the control is copied to step 912. If not, step 902 is executed. In step 902, the user is inquired whether the work state is to be reproduced from the file. If the user answers that the work state is not reproduced from the file, the control is transferred to the initial setting in step 900 to initialize the apparatus and start up the OS. Do. If the user answers that the file is reproduced in step 902, the user is further inquired in step 903 for the name of the work state storage file 200a to be used. An example of the display screen at this time is shown in FIG. Next, in step 904, the name of the work state storage file 200a is analyzed to check whether the file is on the information processing apparatus 17b used as a server. As a result of the investigation, if it is not a file on another information processing apparatus 17b, the control is moved to step 908. If the file is on the information processing apparatus 17b, the network adapter 18a is initialized in step 905, the user inputs a user name and password in step 906, and the user name and password are used in step 907. Log in to the information processing apparatus 17b to make a logical connection. An example of the screen display in step 906 is shown in FIG. Next, in step 908, the saved work type code 201 stored at the time of saving the work state is read by referring to the work state saving file 200a. Next, in step 909, it is checked whether or not the stored model code 201 matches the model code of the information processing apparatus that is executing this program. As described above, in this 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. Have a different model code. Therefore, when the work state storage is performed by the information processing apparatus 17a, and when the work state reproduction is performed by the information processing apparatus 17a or the information processing apparatus 17c, the determination at the step 909 is "match", and the work state reproduction is performed as information. The determination made by the processing device 17d is “mismatch”. If the result of the determination is “mismatch”, the user is informed at step 910 that the model is different, and the user is inquired whether to use another work state storage file 200a. An example of the inquiry screen is shown in FIG. If the user answers that another work state storage file 200a is used, the process returns to step 903. If the user answers that the work state storage file 200a is not used, the work state reproduction process is not performed, and control is shifted to the initial setting in step 900. Initialization and OS startup are performed. If the result of determination in step 909 is “match”, the main memory content 203 of the work state saving file 200a is read out and expanded in the main memory 2 in step 911. As a result, the contents of the main memory 2 shown in FIG. 11 are reproduced. Next, in step 912, the contents of the connection server name address 1008 are examined. If the contents are "0", it is determined that the network is not connected when the work state is saved, and the control is transferred to step 918. If the content of the connection server name address 1008 is not “0”, it is determined that the connection is made to the network, and the initialization of the network adapter 18a in step 913 is executed. Next, in step 914, it is checked whether or not a user name has been input in step 906. If it has not been input, the user inputs a user name and password in step 915. Login to the information processing apparatus 17b is executed using the password. Next, in step 917, the open file information table 1013 on the main memory 2 is referred to. 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 preservation date and time 202 of the work state saving file 200a. If the last modified date is later than the saved date 202, there is a possibility that the contents of the file have changed after the working state is saved. Accordingly, since the file may not be used as it is, a message as shown in FIG. 19 is displayed to alert the user. 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 1011 is referenced to reproduce the contents of each I / O register. Finally, in step 921, the CPU register table 1010 is referenced to reproduce the contents of each register of the CPU1. When step 921 ends, the reproduction of the work state is completed.
[0052]
In this example, if you are connected to the network when saving the work status, the network connection and login operations are automatically performed when the work status is reproduced, so the work status including the network connection status can be reproduced. There is an effect that can be done. In addition, even when a work state is saved while a file on another information processing device used as a server is open, the open state can be reproduced when the work state is reproduced, so the work state can be reproduced correctly. There is an effect. In addition, when reproducing the open state of the file, the working state storage date and time are compared with the last modification date and time of the file, and if the last modification date and time is later, there is a change in the contents of the file after the working state is saved. Since the user is notified of this, there is an effect that the user can perform necessary treatment on the file. In addition, the model code 201 of the information processing apparatus that has performed the storage is stored in the work state storage file 200a. When the work state is reproduced, the model code 201 of the information processing apparatus that performs the reproduction is compared. Since the reproduction is not performed, there is an effect that it is possible to prevent a failure such as a program runaway that occurs when the reproduction is performed on a different model. In addition, since the user can select whether the work state is stored by battery backup of the main memory 2 or the work state storage file 200a, it is possible to connect to the network or to save a set of work states. There is an effect that it is possible to select an optimal work state storage method according to the situation, such as whether to perform high-speed storage and reproduction by battery backup of the main memory 2.
[0053]
Next, a sixth embodiment of the present invention will be described below with reference to FIG. A working state saving file 200b in FIG. 13 shows another example of the working state saving file 200a in the fifth embodiment. In the fifth embodiment, the contents of the main memory 2 are stored as they are as the main memory contents 203. However, in this embodiment, only the memory block used in the main memory 2 is stored as the main memory contents 203b. To do. Specifically, the start address, block size, and main memory contents are stored for each memory block being used based on the memory usage status data provided by the OS. This eliminates the need to store unused main memory data, thereby reducing the file size of the work state storage file 200b and reducing the amount of use of the magnetic disk 16a or 16b storing the work state storage file 200b. There is an effect that the time required for storage and reproduction can be shortened. The method of storing the contents of the main memory 2 in the work state storage file 203b is not limited to the method of using the memory block in use as described above, but the file size of the work state storage file 203b is set using a data compression algorithm or the like. It may be small.
[0054]
Next, a seventh embodiment of the present invention will be described below. In this embodiment, the interrupt program for saving the work state and the reset program for reproducing the work state stored in the ROM 6 in the above-described embodiment are stored on the storage device as program files that can be executed as commands from the OS. Store. FIG. 20 shows a file directory on the magnetic disk 16a of the information processing apparatus 17a in this embodiment. Two types of OSs, OSa and OSb, are stored in the file directory. OSa and OSb have different command program formats, and a common program file cannot be used. The commands and data of each OS are stored under the directories of commands 502a and 502b and the directories of data 503a and 503b, respectively. A work state reproduction program and a work state storage program for OSa are stored in the directory of the command 502a as files of a work state reproduction a 504a and a work state storage a 505a, respectively. The OSb work state reproduction program and work state storage program are stored in the directory of the command 502b as files of work state reproduction b504b and work state storage b505b, respectively. The processing contents of the work state storage a 505a and the work state storage b 505b may be the same as the processing procedures of the interrupt programs 50, 50a, 50b described above. The processing contents of the work state reproduction a504a and the work state reproduction b504b may be the same as the processing procedures of the reset programs 60 and 60b described above. When the user wants to save / reproduce the work state, a work state save / reproduction program corresponding to the type of OS being used is executed as a command. FIG. 21 shows an example of a screen for issuing a command for opening another window and saving the work state during work for creating a graph in a certain window in OSa.
[0055]
According to the present embodiment, since the work state storage and reproduction program can be executed as a command program, the resume function can be realized even in an information processing apparatus that does not have a power supply mechanism or ROM program for resume. is there. In addition, since a work state storage and reproduction program can be selected according to the type of OS, there is an effect that the work state can be easily stored and reproduced even when a plurality of OSs are used.
[0056]
In the embodiments described above, an example in which a magnetic disk device is used as a storage device that does not require battery backup has been described, but an optical disk device or the like may be used as long as battery backup is not required. The display may be a CRT or the like instead of the liquid crystal display 5. Further, the saving and reproduction of the work state may be performed not only when the power is turned off and when the power is turned on again, but also at any timing at which the user wants to suspend or resume the work.
[0057]
Next, an eighth embodiment of the present invention will be described with reference to FIGS.
[0058]
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 establishes a logical connection with the information processing apparatus 17b via the network 19, so that the disk device 16b connected to the information processing apparatus 17b is connected to the own apparatus. You can read and write as if it were a disk unit. While the information processing device 17a and the information processing device 17b are logically connected, the information processing device 17b periodically transmits a connection confirmation request frame to the information processing device 17a at appropriate time intervals. The information processing device 17a holds a logical connection by returning a connection confirmation response frame in response to the connection confirmation request frame. Alternatively, the logical connection is maintained by the information processing apparatus 17a periodically transmitting a connection confirmation notification frame to the information processing apparatus 17b at appropriate time intervals. If the connection confirmation response frame is not returned or the connection confirmation notification frame is not transmitted, the information processing device 17b regards the information processing device 17a to be in an abnormal state and establishes a logical connection. It comes to release.
[0059]
FIG. 22 is a block diagram of an information processing apparatus 17a to which the eighth embodiment of the present invention is applied. In the figure, reference numeral 23 denotes a power control signal line from the network controller 18 to the power controller 9. FIG. 24 is a detailed configuration diagram of the power supply controller 9. 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 controller 9, 95 is a timer used by the power switch controller 92 for timing purposes, and 96 is a power supply line for supplying power to each unit. In the information processing apparatus configured as described above, the resume function according to the present invention operates as follows.
[0060]
First, the procedure in which the information processing apparatus 17a in operation stores the working state at that time and enters the power-off state will be described with reference to the sequence diagram of FIG.
[0061]
It is detected that the resume power switch 10 is pressed while the information processing device 17a is in operation, the voltage of the battery 7 is decreased to a certain value or less, or there is no key input to the keyboard 12 for a certain time. When detected, the power switch controller 92 generates an interrupt requesting the CPU 1 to start processing necessary for powering off through the interrupt signal line 22 (step 101). When the CPU 1 receives the interruption, it starts a work state saving process (step 102). As a method for saving the work state, a method in which the RAM 2 is constituted by a RAM that can be backed up by the battery 7 and the work state including the contents of the display memory 4 is stored and saved in the RAM, and the work state is stored as a disk device. There are a method of saving in 16a, a method of saving the work state as a file in a disk device 16b connected to the information processing device 17b through the network 19, and the like. When the saving of the working state is completed, the CPU 1 writes a specific command indicating the completion of the saving of the working state into the command register 94 to notify the power switch controller 92 of the completion of the working state saving process (step 103). When the power switch controller 92 is notified of the completion of the work state saving process, the power switch controller 92 operates the switch unit 91 to stop power supply to each unit except for the network controller 18, and the network controller 18 is in a power-off state. This is notified (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 apparatus 17a stores the work state and enters a power-off state.
[0062]
Next, a procedure for responding to the connection confirmation request frame transmitted from the information processing apparatus 17b when the information processing apparatus 17a stores the work state and is in a power-off state will be described with reference to the sequence diagram of FIG. To do.
[0063]
When the information processing device 17a is in a power-off state and the connection confirmation request frame is transmitted from the information processing device 17b, the network controller 18 holds the frame reception interrupt to the CPU 1 and passes the power control signal line 23 through the power supply controller 9. A power-on request is issued (step 111). 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 needs to be reproduced, and the switch unit 91 is operated to connect to the power supply line 96. Power is supplied (step 112). However, since the power is temporarily turned on at the request of the network controller 18, power is not supplied to the display device 5. The CPU 1 supplied with the power starts a reset process by a program stored in the ROM 6. The CPU 1 first reads the contents of the status register 93 after turning on the power, 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 controller 9 of the completion of the work state reproduction by writing a specific command to the command register 94, and continues the reproduced process before the power interruption (step 114). When notified of the completion of the work state reproduction process, the power supply controller 9 also notifies the network controller 18 of this and starts the timer 95 (step 115). The network controller 18 notified of the completion of the work state reproduction process issues a frame reception interrupt to the CPU 1 that has been suspended (step 116). The CPU 1 that has received the frame reception interrupt starts protocol processing. In this process, since the received frame is a connection confirmation request frame from the information processing apparatus 17b, the CPU 1 requests the network controller 18 to transmit a 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 apparatus 17b (step 118). Thereafter, when the timer 95 started in step 115 times out, this is notified to the power switch controller 92, and an interrupt requesting the CPU 1 to start processing necessary for power-off is generated through the interrupt signal line 22 (step 119). ). When 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 writes a specific command to the command register 94 to notify the power supply controller 9 of the completion of the work state save (step 121). The notification is received by the power switch controller 92 in the power controller 9, operates the switch unit 91 to stop the power supply to each unit, and notifies the network controller 18 that the power is turned 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 the power on again when the frame is received even when the power is off. It is possible to maintain a logical connection with the information processing apparatus 17b.
[0064]
Finally, a procedure for turning on the power again at the request of the user when the information processing apparatus 17a stores the work state and is in a power-off state will be described with reference to the sequence diagram of FIG.
[0065]
When the resume power switch 10 is pressed in the power-off state, the power switch controller 92 sets in the status register 93 that the power must be reproduced so that the work state is reproduced, and operates the switch unit 91 to operate the power source. Supply of power to the supply line 96 is started (step 131). Here, since power is turned on again at the request of the user, power is supplied to all parts of the information processing apparatus 17a including the display device 5. The CPU 1 supplied with the power starts a reset process by a program stored in the ROM 6. The CPU 1 first reads the contents of the status register 93 after turning on the power, recognizes that the work state needs to be reproduced, and starts the work state reproduction process (step 132). When the reproduction of the work state is completed, the CPU 1 writes a specific command to the command register 94 to notify the power controller 9 of the completion of the work state reproduction, and continues the reproduced process before the power interruption (step 133). . When notified of the completion of the work state reproduction process, the power supply controller 9 notifies the network controller 18 of the completion (step 134).
[0066]
Since the power is turned on again at the request of the user, the timer 95 is not started. The network controller 18 immediately notifies the CPU 1 by an interrupt when a frame is subsequently received by the notification. With the above processing, the user can continue the work by reproducing the work state when the power is turned off.
[0067]
Next, a ninth embodiment of the present invention will be described with reference to FIGS.
[0068]
FIG. 28 is a block diagram of the information processing apparatus 17a according to the ninth embodiment of the present invention.
[0069]
In the figure, reference numeral 24 denotes a timer unit for detecting the passage of a specified time.
[0070]
Among the operations of the resume function according to the present embodiment, the operating information processing apparatus 17a saves the working state and turns off the power, and the procedure of turning the power on again at the request of the user, respectively. The network controller 18 in the sequence diagrams of FIGS. 25 and 27 is the same as the timer unit 24. When the timer unit 24 is notified of the power-off state, the timer unit 24 immediately notifies the power-supply controller 9 without notifying the CPU 1 that the specified time has elapsed, and when the timer unit 24 is notified of the release of the power-off state. Again, the CPU 1 is immediately notified of the elapse of the specified time.
[0071]
Here, the procedure in which the information processing device 17a transmits a connection confirmation notification frame to the information processing device 17b when the timer unit 24 detects the elapse of the specified time during the power-off state is described with reference to the sequence diagram of FIG. explain.
[0072]
When the information processing apparatus 17a is in a power-off state, when the timer unit 24 detects that the specified time has elapsed, the timer unit 24 issues a power-on request to the power controller 9 through the power control signal line 23, and a time-out interrupt to the CPU 1 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 needs to be reproduced, and the switch unit 91 is operated to connect to the power supply line 96. Supply of power is started (step 142). However, since the power is temporarily turned on upon request of the timer unit 24, power is not supplied to the display device 5. The CPU 1 supplied with the power starts a reset process by a program stored in the ROM 6. The CPU 1 first reads the contents of the status register 93 after turning on the power, 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 writes a specific command to the command register 94 to notify the power controller 9 of the completion of the reproduction of the work state, and continues the reproduced process before the power interruption (step 144). When notified of the completion of the work state reproduction process, the power supply controller 9 notifies the timer unit 24 of the completion and starts the timer 95 (step 145). The timer unit 24 notified of the completion of the work state reproduction process issues a time-out interrupt to the CPU 1 that has been suspended (step 146). The CPU 1 that has received the timeout 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 apparatus 17b (step 147). Thereafter, when the timer 95 started in step 145 times out, this is notified to the power switch controller 92, and an interrupt requesting the CPU 1 to start processing necessary for power-off is generated through the interrupt signal line 22 (step 148). ). When the CPU 1 receives the interruption, 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 to the command register 94 to notify the power supply controller 9 of the completion of the work state save (step 150). The notification is received by the power switch controller 92 in the power controller 9, and the switch unit 91 is operated to stop the power supply to each unit and notify the timer unit 24 that the power supply is turned off again (step 151). ). With the above processing, the information processing device 17a can transmit a connection confirmation notification frame to the information processing device 17b by temporarily turning on the power again by a timer interrupt even in a power-off state. It is possible to maintain a logical connection with the information processing apparatus 17b.
[0073]
Next, a tenth embodiment of the present invention will be described with reference to FIG.
[0074]
FIG. 30 is a sequence diagram showing processing of the tenth embodiment of the present invention. In this sequence diagram, when the information processing apparatus 17a configured as shown in FIG. 22 is in a power-off state while maintaining a logical connection with the information processing apparatus 17b, a message to be displayed to the user from the information processing apparatus 17b. This shows the processing when a frame including it is received.
[0075]
When the network controller 18 receives a frame including a message to be displayed to the user from the information processing apparatus 17b, each unit of the network controller 18, the power supply controller 9, and the CPU 1 first performs a series of processing 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. When receiving a frame reception interrupt from the network controller 18, the CPU 1 starts protocol processing for the frame (step 167). In this process, when the CPU 1 finds that the frame includes a message to be displayed to the user, the CPU 1 writes a specific command in the command register 94 and notifies the power controller 9 that it is not necessary to turn off the power again. (Step 168) Further, the message is displayed on the display device 5 through the display controller 3 (Step 169). The power switch controller 92 in the power controller 9 that has received the notification stops the timer 95 started in step 165 and starts the power supply to the display device 5 that was not supplied in step 162. Is operated (step 170). Through the above processing, when a message to be displayed to the user is received in a power-off state while maintaining a logical connection with the information processing device 17b, the message can be displayed by automatically turning on the power again. Become. In this embodiment, the received message is displayed unconditionally. However, before displaying the message in step 169, the user is inquired whether to display the message, and the display instruction is displayed. You may make it display only when there exists. If there is no instruction within a certain time, that is, if there is no user in front of the information processing apparatus 17a, the message is not displayed, the working state is saved again, and the power supply controller 9 is instructed to turn off the power. Like that.
[0076]
【The invention's effect】
As described above, according to the present invention, a plurality of work states can be saved and reproduced independently, so that the user can perform other work while keeping one work state. In addition, since the work states of a plurality of users can be stored and reproduced independently, even when a plurality of users use the same information processing apparatus and use the resume function, security and usability are not impaired. In addition, it is possible to perform work state storage that does not require backup of the main memory by the battery, and it is possible to realize the resume function even in an information processing apparatus that does not have a battery backup function. In addition, since the work state is stored on another information processing apparatus connected via the network, the work state is reproduced on an information processing apparatus other than the information processing apparatus in which the user interrupted the work and saved the work state. And an information processing system excellent in mobility can be provided. In addition, even when logically connected to other information processing devices via a network, the work state can be saved and restored normally, and it has excellent resume functions such as improved user convenience and power saving of information processing devices. This feature can also be used in a network-connected information processing apparatus. In addition, even when the power is temporarily turned off for the purpose of power saving or the like while connected to the network, the message can be displayed by automatically turning on the power again when a message for the user is received. Therefore, the resume function can be used without impairing the serviceability of the information processing apparatus system connected to the network, such as a mail or message transmission function.
