  The RAM 11 is composed of a semiconductor memory or the like that can be accessed at high speed from the CPU 10. However, since the RAM 11 is volatile, the stored information is lost when the information processing apparatus 1 is powered off. Of the information stored in the RAM 11, information required when the information processing apparatus 1 is turned on and the OS is started up is backed up, that is, saved in a nonvolatile storage device such as the Flash ROM 12. When the processing apparatus 1 is turned on and the OS is activated, the processing is restored from the flash ROM 12 to the RAM 11, that is, restored. The flash ROM 12 is a semiconductor memory such as a rewritable nonvolatile flash memory, and stored information is not lost even when the power is turned off. In general, a magnetic disk device is used as a non-volatile storage device. However, a handy-type small computer such as a handy terminal has relatively low power consumption and shock resistance compared to a magnetic disk device. An excellent flash memory is used.

  Registry information that defines execution conditions for executing programs such as the OS and application programs is stored in the RAM 11. When the information processing apparatus 1 is powered off, the CPU 10 stores the registry information stored in the RAM 11. Retreat to the Flash ROM 12. When saving the registry information to the flash ROM 12, the CPU 10 adds the additional information to the registry information and stores it in each of the plurality of areas. The additional information includes, for example, a checksum value for detecting whether there is an error in the registry information.

  When the information processing apparatus 1 is powered on, the CPU 10 checks whether there is an error in the registry information in one of the areas of the Flash ROM 12 that stores the registry information. When there is no error, the registry information with no error is written into the RAM 11. When there is an error, the registry information of one of the areas other than the area of the registry information where the error is checked is written into the RAM 11. Details of the information stored in the RAM 11 and the flash ROM 12 will be described later.

The information processing apparatus 1 further includes an LCD (Liquid Crystal Display) 14 that is a liquid crystal display having a display screen for displaying information, an LCD Controller 15 that controls the LCD 14 according to an instruction from the CPU 10, and a CF CARD (Compact) that is an external memory.

  The first storage means and the storage means are, for example, the RAM 11, the second storage means is, for example, the Flash ROM 12, and the save means, error detection means, and return means are functions of a program executed by the CPU 10, for example. is there.

  Thus, since the flash ROM 12 as the second storage means is a different type of storage medium from the RAM 11 as the first storage means, the characteristics required for backing up the registry information as the second storage means A storage medium having the following can be used. A flash memory can be used as a storage medium having characteristics necessary for backing up registry information, for example, a nonvolatile storage medium.

  In other words, since the second storage means is composed of a different type of storage medium from the first storage means, a storage medium having characteristics necessary for backing up the registry information is used as the second storage means. be able to. Therefore, a storage medium having the characteristics necessary for backing up the registry information can be used as the second storage means, so that the stored information is not lost even when the power is turned off. Can be used as the second storage means.

  FIG. 2 is a diagram showing allocation of memory areas of the flash ROM 12 shown in FIG. The flash ROM 12 has a memory capacity of 64 MB (megabytes), for example, and is composed of a 32 MB OS image storage area, a 1 MB registry storage area, and a 31 MB flash disk area. The OS image storage area is an area for storing an OS to be loaded into the RAM 11, and also stores default registry information, that is, registry information in an initial state.

  The registry storage area is divided into two areas of A side and B side, and each has a memory capacity of 512 KB. The A side and the B side have the same data structure, and have a header part and an actual data part, respectively. In the header part, the flag information for managing the registry information, the actual data size indicating the data length of the actual data part, the sum check value for checking whether there is an error in the registry information, and the registry information are stored in the registry Additional information such as the number of writes written in is stored. Registry information is stored in the actual data portion. In the embodiment shown in FIG. 2, the registry storage area has been described as two faces, A and B. However, it is possible to secure three or more areas and save three or more registry information. .

  The flash disk area is configured as a flash disk that emulates a magnetic disk device, and is accessed from the OS as a magnetic disk device. In the Flash Disk area, a backup file of registry information is stored.

  FIG. 3 is a diagram for explaining the backup and restore operations of registry information stored in the RAM 11 shown in FIG. The RAM 11 has a memory capacity of 64 MB, for example, and is divided into a program execution memory area and a data storage memory area. Programs such as an OS and application programs are stored in the program execution memory area. The data storage memory area is configured as a RAM Disk that emulates a magnetic disk device, and is accessed from the OS as a magnetic disk device. In the data storage memory area, registry information, data to be processed, and the like are stored.

  An arrow B1 shown in FIG. 3 indicates a case in which the registry information stored in the data storage memory area of the RAM 11 is backed up in the flash disk area of the flash ROM 12 by the registry backup tool incorporated in the information processing apparatus 1. Show. Registry information is stored in the data storage memory area of the RAM 11 when the OS is operating. The registry backup tool is a tool including a program for backing up registry information, and the user can back up the registry information using the registry backup tool as necessary. When the registry information stored in the data storage memory area of the RAM 11 is backed up using the registry backup tool, a back file file of the registry information is generated in the flash disk area of the flash ROM 12.

  An arrow B2 shown in FIG. 3 indicates a case where the registry information stored in the data storage memory of the RAM 11 is backed up, that is, saved in the registry storage area of the flash ROM 12. When the information processing apparatus 1 is turned off, the information processing apparatus 1 stores the registry information stored in the data storage memory area on each of the A side and B side of the registry storage area of the Flash ROM 12.

  As described above, when the information processing apparatus 1 is powered off, the registry information stored in the RAM 11 as the first storage means is stored in the registry storage area of the flash ROM 12 as the second storage means. Therefore, the registry information is not saved during the operation of the information processing apparatus 1.

  That is, when the information processing apparatus 1 is powered off, the registry information stored in the first storage means is stored in the second storage means. Therefore, during the operation of the information processing apparatus 1, the registry information is stored. Is not stored in the second storage means. Therefore, when the information processing apparatus 1 is powered off, the registry information is saved, and the registry information is not saved during the operation of the information processing apparatus 1, thereby avoiding a decrease in processing performance during the operation. Can do.

  Alternatively, when the power is turned off, the registry information stored in the data storage memory area of the RAM 11 is not stored unconditionally in each of the A side and B side of the registry storage area of the Flash ROM 12. When the power is turned off after the registry information stored in the data storage memory of the RAM 11 is changed, the registry information stored in the data storage memory area is stored in the A and B sides of the registry storage area. You may make it memorize | store in each.

  As described above, when the information processing apparatus 1 is powered off after the registry information stored in the data storage memory of the RAM 11 serving as the first storage means is changed, the information is stored in the data storage memory of the RAM 11. The stored registry information is stored in the A and B sides of the registry storage area of the flash ROM 12 as the second storage means. When the registry information is not changed, it is stored in the data storage memory of the RAM 11. Registry information is not stored in the Flash ROM 12.

  That is, when the power is turned off after the registry information stored in the first storage unit is changed, the registry information stored in the first storage unit is stored in the second storage unit. When the registry information is not changed, the registry information is not stored in the second storage unit. Therefore, even when the information processing apparatus 1 is powered off, the registry information is saved only when the registry information is changed. Therefore, when the registry information is not changed, the registry information saving time when the power is turned off. Can be reduced.

  Further, whether or not there is an error in the registry information stored in the A and B sides of the registry storage area of the flash ROM 12 when the power is turned off without changing the registry information stored in the data storage memory of the RAM 11 Are checked using the checksums stored in the header parts of the A and B sides, respectively. When an error is detected in the registry information stored on either side, the registry information stored on the A and B sides of the registry storage area of the flash ROM 12 is stored in the data storage memory area. If no error is detected in the registry information on either side, the registry information stored in the A and B sides of the registry storage area of the Flash ROM 12 may not be updated. Good.

  Thus, when an error is detected in any one of the registry information stored in the flash ROM 12 as the second storage means, the registry stored in the RAM 11 as the first storage means. Since the information is updated by the registry information stored in the A and B surfaces of the flash ROM 12, the registry information stored in the flash ROM 12 can be updated to the error-free registry information.

  That is, when an error is detected in any one of the plurality of registry information stored in the second storage unit, all the registry information stored in the second storage unit is stored in the first storage unit. Therefore, the registry information stored in the second storage means can be updated to error-free registry information. Therefore, when an error is detected in any one of the plurality of registry information stored in the second storage unit, all the registry information stored in the second storage unit is not error-free. Since the registry information is updated, the reliability of the registry information saved in the second storage unit can be improved.

  Alternatively, when an error is detected in the registry information on either side, it is also possible to update only the registry information on the side where the error is detected, instead of updating both the A side and the B side. Specifically, when the power is turned off without changing the registry information stored in the data storage memory, first, whether or not there is an error in the registry information stored in the A side of the registry storage area of the Flash ROM 12 Is checked using the checksum stored in the header part of the A side. If there is an error, the registry information stored in the A side of the registry storage area is updated with the registry information stored in the data storage memory area. If there is no error, the registry information stored in the A side of the registry storage area is not updated.

  Next, whether or not there is an error in the registry information stored in the B side of the registry storage area of the flash ROM 12 is checked using the checksum stored in the header part of the B side. When there is an error, the registry information stored in the B side of the registry storage area is updated with the registry information stored in the data storage memory area. If there is no error, the registry information stored in side B of the registry storage area is not updated.

  As described above, when an error is detected in the registry information stored in the A side of the Flash ROM 12 as the second storage unit, the registry information stored in the A side is stored in the RAM 11 as the first storage unit. Updated with the stored registry information, and when an error is detected in the registry information stored on the B side of the flash ROM 12, the registry information stored on the B side is updated with the registry information stored in the RAM 11. Therefore, the registry information of the surface where the error is detected can be updated to the registry information having no error.

  That is, among the plurality of registry information stored in the second storage unit, the registry information in which the error is detected is updated with the registry information stored in the first storage unit. The detected registry information can be updated to error-free registry information. Therefore, only the registry information in which an error is detected among the plurality of registry information is updated to the registry information without an error, so that the saving time of the registry information can be shortened.

  An arrow R2 shown in FIG. 3 indicates a case where the registry information that has been backed up, that is, saved in the registry storage area of the flash ROM 12 is restored, that is, restored to the data storage memory of the RAM 11. When the OS is started, for example, when the information processing apparatus 1 is turned on, whether or not there is an error in the registry information stored in the A side of the registry storage area of the Flash ROM 12 is displayed in the A side header part. Check using the stored sum check value. If there is no error, the registry information stored in the A side is stored in the data storage memory of the RAM 11. When there is an error, the registry information stored in the B side is stored in the data storage memory of the RAM 11.

  In each of the embodiments shown in FIG. 3, the registry storage area has been described as the two faces A and B. However, it is possible to secure three or more areas and save three or more registry information. is there.

  In this way, since a plurality of registry information is stored and saved in the flash ROM 12 as the second storage means, even if an error occurs in any of the saved registry information, it is saved. The registry information stored in the RAM 11 serving as the first storage means can be restored by other registry information.

  That is, since the registry information is stored as a plurality of registry information in the second storage means, even if an error occurs in a part of the stored registry information, the other registry information Registry information stored in the first storage means can be restored. Therefore, even if an error occurs in a part of the plurality of registry information stored in the second storage unit, the registry information stored in the first storage unit is changed to the registry information by another registry information. Since it can be restored, the registry information can be restored in a short time and more reliably.

  Further, when the OS is started and the registry information stored in the flash ROM 12 as the second storage means is restored to the RAM 11 as the first storage means, that is, when the restoration is restored, a plurality of saved registry information is restored. If there is an error in some of the registry information, the registry information in the RAM 11 is repaired by the other saved registry information, so that the registry information can be repaired as part of the OS startup process.

  That is, when the OS is started and one registry information of the plurality of registry information stored in the second storage unit is stored as new registry information in the first storage unit, the plurality of stored registry information is stored. If there is an error in some of the registry information, the registry information in the first storage means is repaired by the other stored registry information, so that the registry information is restored as part of the OS startup process. Can be performed. Therefore, when the OS is started and the saved registry information is stored in the first storage means as new registry information, the registry information is restored as part of the OS startup process. Can be performed without making the user aware of it.

  Alternatively, if there is an error in the registry information stored in the A side of the registry storage area, the registry information stored in the B side is not stored in the data storage memory of the RAM 11 unconditionally. After checking whether or not there is an error in the stored registry information using the sum check value stored in the header part of the B side, the registry information stored in the B side is stored in the data storage memory of the RAM 11. You may remember. That is, whether or not there is an error in the registry information stored in the B side is checked using the sum check value stored in the header part of the B side, and if there is no error, the registry stored in the B side Information is stored in the data storage memory of the RAM 11.

  When there is an error in the registry information stored in the A side and the B side, as shown by the arrow R1 in FIG. 3, the backup data of the registry information in the flash disk area of the flash ROM 12 is used to store data in the RAM 11. Restore memory registry information. It is checked whether or not there is a backup file of registry information in the flash disk area. When there is a backup file, the registry information of the flash disk area is stored in the data storage memory of the RAM 11. When there is no backup file of registry information in the Flash Disk area, the default registry information stored in the OS image storage area of the Flash ROM 12 is stored in the data storage memory of the RAM 11.

  As described above, even if an error is detected in the registry information on the A and B sides of the registry storage area, if there is a backup file of the registry information stored in the flash disk area, the registry information of the RAM 11 is stored by the backup file. Since it can be repaired, the reliability can be further improved.

  FIG. 4 is a flowchart showing an example of a backup processing procedure of the registry information shown in FIG. This flowchart shows a processing procedure in which the CPU 10 backs up the registry information in the flash disk area. When the information processing apparatus 1 is turned on with no application program installed in the information processing apparatus 1, the process proceeds to step S1.

  In step S1, the hardware stored in the information processing apparatus 1 is initialized by the program stored in the BIOS ROM 13, and the OS stored in the OS image storage area of the flash ROM 12 is stored in the program execution memory area of the RAM 11. Load it. In step S2, when the OS is loaded into the program execution memory area of the RAM 11, the loaded OS is activated. At this time, the default registry information stored in the OS image storage area of the flash ROM 12, that is, the registry information in the initial state is loaded into the data storage memory area of the RAM 11.

  In step S3, an application program is installed. In step S4, an operating environment such as a system, that is, an OS and an installed application program is set. The set operating environment is registered in the registry information loaded in the data storage memory area of the RAM 11, and the registry information is changed from the initial state. In step S5, the registry backup tool is executed, and the registry information stored in the data storage memory area of the RAM 11 is stored as a backup file of the registry information in the flash disk area of the flash ROM 12 in accordance with an instruction operated by the user. Then, the process ends.

  As described above, generation of a backup file of registry information in the flash disk area of the flash ROM 12 is performed according to an instruction from the user, and depending on the user, a backup file of registry information is not generated in the flash disk area of the flash ROM 12. There is also. When a backup file of registry information is generated in the flash disk area of the flash ROM 12, even if an error is detected in the registry information on the A side and B side of the registry storage area, the backup file of this registry information is used. The registry information in the RAM 11 can be restored.

  FIG. 5 is a flowchart showing another example of the backup procedure of the registry information shown in FIG. This flowchart shows a processing procedure in which the CPU 10 backs up the registry information stored in the RAM 11 to the registry storage area of the flash ROM 12. When the information processing apparatus 1 is powered off, the process proceeds to step T1.

  In step T1, it is determined whether or not the registry information stored in the data storage area of the RAM 11 has been changed. Whether the registry information has been changed is determined by, for example, storing change information indicating that the registry information has been changed in the area of the data storage area of the RAM 11 when the registry information has been changed. It is possible to determine whether or not a change has been made by referring to the change information. When the registry information is changed, the process proceeds to step T8, and when the registry information is not changed, the process proceeds to step T2.

  In step T2, it is determined whether registry information is stored in the A side of the registry storage area of the flash ROM 12. Whether or not the registry information is stored in the A side of the registry storage area can be determined by referring to the flag information of the header part stored in the A side, for example. When registry information is not stored on the A side, the process proceeds to step T6, and when registry information is stored on the A side, the process proceeds to step T3. In step T3, it is checked whether or not there is an error in the registry information stored in the A side of the registry storage area using the sum check value stored in the header portion. When there is an error, the process proceeds to step T6, and when there is no error, the process proceeds to step T4.

  In step T4, it is determined whether or not registry information is stored in the B side of the registry storage area of the flash ROM 12. Whether or not registry information is stored on the B side of the registry storage area can be determined by referring to, for example, the flag information of the header portion stored on the B side. When the registry information is not stored on the B side, the process proceeds to step T7, and when the registry information is stored on the B side, the process proceeds to step T5. In step T5, it is checked whether or not there is an error in the registry information stored in the B side of the registry storage area, using the thumbchuck value stored in the header portion. When there is an error, the process proceeds to step T7, and when there is no error, the process ends.

  In step T6, the registry information stored in the data storage area of the RAM 11 is stored in the A side of the registry storage area of the flash ROM 12, and the process proceeds to step T4. In step T7, the registry information stored in the data storage memory area of the RAM 11 is stored in the B side of the registry storage area of the flash ROM 12, and the process ends. In step T8, the registry information stored in the data storage area of the RAM 11 is stored in the A side of the registry storage area of the flash ROM 12, and then the process proceeds to step T7.

  In the processing procedure shown in FIG. 5, the registry information stored in the A side and B side of the registry storage area is individually checked, and the registry information in which an error is detected is stored in the data storage memory of the RAM 11. When the registry information stored in the area is updated but an error is detected in any of the registry information stored in the A and B sides of the registry storage area, the A and B side registry information May be updated with the registry information stored in the data storage memory area of the RAM 11.

  FIG. 6 is a diagram illustrating an example of a processing procedure for restoring the registry information illustrated in FIG. 3. This flowchart shows a processing procedure in which the CPU 10 restores the registry information to the RAM 11, that is, restores it. When the information processing apparatus 1 is turned on while an application program or the like is already installed in the information processing apparatus 1, the process proceeds to step U1.

  In step U1, the hardware stored in the information processing apparatus 1 is initialized by the program stored in the BIOS ROM 13, and the OS stored in the OS image storage area of the flash ROM 12 is stored in the program execution memory area of the RAM 11. Loaded. In step U2, it is determined whether or not the registry information is stored in the A side of the registry storage area of the flash ROM 12. Whether or not the registry information is stored in the A side of the registry storage area can be determined by referring to the flag information of the header part stored in the A side, for example. When registry information is not stored on the A side, the process proceeds to step U5. When registry information is stored on the A side, the process proceeds to step U3.

  In step U3, it is checked whether or not there is an error in the registry information stored in the A side of the registry storage area using the sum check value stored in the header portion. When there is an error in the registry information stored in the A side, the process proceeds to Step U5, and when there is no error in the registry information stored in the A side, the process proceeds to Step U4. In step U4, the registry information stored in the A side of the registry storage area of the flash ROM 12 is copied to the data storage memory area of the RAM 11, and the process ends.

  In step U5, it is determined whether or not the registry information is stored in the B side of the registry storage area of the flash ROM 12. Whether or not registry information is stored on the B side of the registry storage area can be determined by referring to, for example, the flag information of the header portion stored on the B side. When registry information is not stored on the B side, the process proceeds to step U8. When registry information is stored on the B side, the process proceeds to step U6.

  In step U6, whether or not there is an error in the registry information stored in the B side of the registry storage area is checked using the sum check value stored in the header portion. When there is an error in the registry information stored in the B side, the process proceeds to step U8, and when there is no error in the registry information stored in the B side, the process proceeds to step U7. In step U7, the registry information stored in the B side of the registry storage area of the flash ROM 12 is copied to the data storage memory area of the RAM 11, and the process ends.

  In step U8, it is determined whether there is a backup file of registry information in the flash disk area. Whether there is a backup file can be determined by searching whether the file name of the backup file in the registry information is in the Flash Disk area. When there is a backup file of registry information in the Flash Disk area, the process proceeds to Step U9, and when there is no backup file of registry information in the Flash Disk area, the process proceeds to Step U10.

  In step U9, the registry information of the backup file stored in the flash disk area is copied to the data storage memory area of the RAM 11, and the process ends. In step U10, the default registry information stored in the OS image storage area of the flash ROM 12, that is, the registry information in the initial state is copied to the data storage memory area of the RAM 11, and the process ends. When the default registry information is copied, it does not have the same contents as the registry information before the information processing apparatus 1 is turned off. For example, it is necessary to repair the registry information by the same processing procedure as the flowchart shown in FIG. is there.

  In each of the embodiments shown in FIGS. 4 to 6, the registry storage area is described as the A side and the B side. However, it is possible to secure three or more areas and save three or more registry information. is there. The first storage unit is, for example, the RAM 11, and the second storage unit is, for example, the flash ROM 12.

  As described above, since a plurality of registry information is stored and saved in the flash ROM 12 as the second storage unit, even if an error occurs in any of the saved registry information, it is saved. The registry information stored in the RAM 11 serving as the first storage unit can be restored by using other registry information.

  That is, since the registry information is stored as a plurality of registry information in the second storage unit, even if an error occurs in a part of the stored registry information, the other registry information Registry information stored in the first storage unit can be restored. Therefore, even if an error occurs in a part of the plurality of registry information stored in the second storage unit, the registry information stored in the first storage unit is repaired by other registry information. Therefore, the registry information can be restored in a short time and more reliably.

  Furthermore, since the information processing apparatus 1 automatically repairs the registry information and loads it into the RAM 11, it is possible to avoid an erroneous operation that may occur when the user manually repairs the registry information. Can prevent the failure. Furthermore, it is possible to quickly determine the cause of the failure by leaving the automatic repair as the failure recovery log, that is, the history information of the failure recovery, thus improving the maintenance efficiency. In addition, the maintenance cost of the information processing apparatus 1 can be reduced.

  If three or more areas are secured in the registry storage area and three or more registry information are saved, the backup time for storing the registry information on the RAM 11 in the flash ROM 12 when the information processing apparatus 1 is turned off. Will increase. As the backup time increases, the time from when the user presses the power-off switch to when the power is actually turned off increases, which causes a problem in operability. In order to increase the probability that the registry information can be restored and to ensure operability when the power is turned off, it is preferable to configure the registry storage area with two surfaces.

  In each of the above-described embodiments, the registry information is saved to the flash ROM 12 when the information processing apparatus 1 is powered off. For example, the registry information may be saved when the user instructs it, or periodically. For example, the registry information may be saved at time intervals such as every 12 hours or every 48 hours.

  The information processing apparatus 1 described above has been described by taking a handy terminal as an example. However, the information processing apparatus 1 is a computer that operates using registry information, that is, setting information such as an OS, such as a mobile terminal such as a PDA, a POS terminal, a personal computer, and a backup system. In contrast, the present invention can be suitably implemented.

It is a hardware block diagram of the information processor 1 which is one embodiment of the present invention. It is a figure which shows the allocation of the memory area of Flash ROM12 shown in FIG. It is a figure for demonstrating the operation | movement of backup and a restoration of the registry information memorize | stored in RAM11 shown in FIG. 4 is a flowchart illustrating an example of a backup processing procedure for registry information illustrated in FIG. 3. 4 is a flowchart showing another example of the backup procedure of the registry information shown in FIG. 3.
