Description

  The present invention relates to a computer startup method for shortening the time required from the time the computer is turned on until the initialization of the OS / middleware / application ends.

  As a conventional computer startup time reduction method, the work is interrupted, the memory image at that time is saved in the external storage device, the power is turned off, and when the computer is turned on again, it is saved from the external storage device to the main memory. There is a hibernation method that unfolds the image and keeps working.

  In addition, the memory image immediately after the OS or the like is started is saved in the external storage device, the memory image saved when the computer is started is expanded from the external storage device to the main memory, and the work is resumed from the state immediately after the start. A scheme has been proposed. In these cases, the memory image storage area by hibernation and the memory image storage area in the state immediately after startup are prepared separately, and when the power is turned on, the hibernation resume is performed according to the previous termination condition or the memory immediately after the initialization is completed. It is determined whether or not to resume using an image, and a resume process is performed (see, for example, Patent Document 1 and Patent Document 2).

JP 10-207588 A JP 2001-14050 A

Conventional acceleration of booting by loading a memory image such as hibernation is based on the premise that a main loader image is acquired and loaded using a boot loader that is a program for transferring an OS from a disk to a memory. Therefore, it is necessary to provide the boot loader with a function for saving and loading the main memory image.
Also, after loading the memory image, the program is always restarted from the state immediately after image acquisition, so if you want another program to start immediately according to the situation at startup, the memory image just before the program startup selection is There was no choice but to save or save a plurality of main memory images in advance. In the former case, the activation time is increased by the program activation selection process, and in the latter case, a storage device for storing a plurality of main memory images is required.

The present invention has been made in order to solve the above-described problems. The main memory image loading process is included in the OS initialization process, and which program is set in the operating state after the image loading in accordance with the activation factor. Even when there are a plurality of programs that start from the power-on according to the situation, by providing a mechanism for determining whether the target program is operating by operating the startup program management information in the OS It is an object of the present invention to provide a computer startup time reduction method that speeds up the startup process in all cases, that is, reduces the time required from the start of startup to the completion of program startup.
Also, a computer startup time reduction method that eliminates the need for an extra image storage area by implementing it on the basis of a single main storage image and eliminates the need for a boot loader and BI / OS support by completing the processing inside the OS. The purpose is to provide.

The computer startup time shortening method according to the present invention includes an OS initialization process setting storage unit that stores OS (Operating System) initialization process information,
An initialization completion memory image storage means for storing an initialization completion memory image of each program at the time when initialization of each program of the OS, middleware, and application is completed;
Main storage means loaded with the initialization completion memory image stored in the initialization completion memory image storage means;
Whether to start each program of OS, middleware, and application based on the OS initialization processing information stored by the OS initialization processing setting storage means, or to start the program to be started first from among the programs, An OS initialization process selection means to select,
When the OS initialization process selection unit selects to start the first program to be started, the initialization completion memory image stored in the initialization completion memory image storage unit is mainly used. Memory image loading means for loading into the storage means;
Activation program selection means for selecting a program to be activated first from the initialization completion memory image loaded in the main storage means.

  As described above, the present invention completes initialization of each program when initialization is completed when it is selected to start the program to be started first from among the OS, middleware, and application programs. By loading a memory image into the main memory means and selecting a program to be activated first from the initialization completion memory image loaded in the main memory means, the time taken from the start of the start to the completion of the program start can be reduced. It can be shortened.

Embodiment 1 FIG.
Embodiment 1 of the present invention will be described below with reference to the drawings.
FIG. 1 is a configuration diagram of a computer startup time reduction method according to the first embodiment. In FIG. 1, reference numeral 100 denotes a boot loader, which is a program for transferring an OS (Operating System) from a disk to a memory. Reference numeral 110 denotes an OS initialization process, which indicates various initialization processes necessary for the OS to operate. The OS initialization process 110 includes an OS initialization process selection unit 111, a normal initialization unit 112, a memory image load unit 113, a startup factor determination unit 114, and a startup program selection unit 115.

  The OS initialization process selection unit 111 is a unit for selecting an OS initialization process. The OS initialization process includes two types of startup modes: a normal startup process described later, and a process that loads and starts a memory image proposed in the present invention. The normal initialization unit 112 performs a startup process when the OS initialization process selection unit 111 selects a normal OS startup process. The memory image loading unit 113 operates when a process for starting a memory image is selected by the OS initialization processing selection unit 111.

  Note that the memory image is the contents of the main memory (memory) acquired at the moment when the system startup is completed, and the activation of the memory image means that the memory image is loaded into the main memory (memory) and activated. Show. The normal initialization unit 112 or the memory image loading unit 113 is selected based on the OS initialization process information stored in the OS initialization process setting storage area 130.

  In addition, the activation factor determination unit 114 and the activation program selection unit 115 perform processing after the memory image loading is completed. Here, the activation factor determination unit 114 is a unit that determines what the activation factor is. For example, the activation factor determination unit 114 determines whether the activation factor is activated by pressing the power button or the timer. The activation program selection means 115 is a means for selecting an activation program corresponding to this activation factor based on the activation factor determined by the activation factor determination means 114, that is, an activation program to be activated, and an activation program selection table. According to 154, the activation program to be activated is selected.

Reference numeral 120 denotes each program initialization means.
Reference numeral 130 denotes an OS initialization process setting storage area (OS initialization process setting storage unit), which stores OS initialization process information. Here, the OS initialization process information is information for determining whether the OS initialization process selection unit 111 selects the normal initialization unit 112 or the memory image load unit 113 as a startup process at the time of OS initialization. In the OS initialization processing setting storage area 130, either normal startup is executed by the normal initialization unit 112, or the initialization completion memory image is loaded by the memory image loading unit 113 and startup is executed. Is saved.

  Reference numeral 140 denotes an initialization completion memory image storage area (initialization completion memory image storage unit), and all programs of the system, that is, all programs of the OS, middleware, and applications are executed by each program initialization unit 120 during the OS initialization process. This is a storage area in which an initialization completion memory image at the time when initialization is completed (normal initialization processing completion time) is stored in advance.

Reference numeral 150 denotes a main memory (main memory means). The main memory 150 indicates a memory, and the configuration of the main memory 150 is divided by a software logical configuration. The contents of the main memory 150 are managed by the OS. Basically, it is divided into an area used by the OS itself, an area used exclusively by each program, and a shared memory area.
Reference numeral 151 denotes OS data on the main memory 150, and reference numerals 152 and 153 denote program data on the main memory 150. Reference numeral 154 denotes an activation program selection table in which activation programs to be activated are recorded for each activation factor. Reference numeral 160 denotes activation completion display means for performing display so that the user can recognize the activation completion.

FIG. 2 is an explanatory diagram showing the contents of the OS data 151. In FIG. 2, 201 is program management information, and 202 is program information being executed. A program that can be executed after initialization is registered in the program management information 201, and a program that is being executed is registered in the running program information 202. The program management information 201 and the running program information 202 are This is information managed by the OS so that the OS can move each program simultaneously by TSS (Time Sharing System) or the like.

Next, the computer high-speed startup process will be described with reference to the flowchart of FIG.
FIG. 3 is a flowchart showing the processing procedure of the fast startup processing of the computer.
When the startup process is started, the OS initialization process 110 is called by the boot loader 100 in step S300. Here, the OS initialization processing 110 is each processing required for the system to start operating after the OS is loaded, and is a part of the OS.

  Next, the OS initialization process selection unit 111 reads the OS initialization process information recorded in the OS initialization process setting storage area 130 in step S301, and refers to the read OS initialization process information in step S302. Then, it is selected whether to execute normal startup or to load and start an initialization completed memory image.

  If execution of normal startup is selected in step S302, after the normal initialization unit 112 executes normal OS initialization processing in step S303, each program initialization unit 120 performs normal program startup / Initialization is executed, and the startup process ends. Here, the normal initialization process indicates a conventional general computer (OS) startup process.

  On the other hand, when it is selected to load and start the initialization completion memory image in step S302, the initialization completion memory image stored in the initialization completion memory image storage area 140 by the memory image loading unit 113 in step S305. Are loaded into the main memory 150.

  In step S306, the activation factor determination unit 114 determines what activation factor the activation process has occurred. Here, in a computer with multiple activation factors, such as "Power button turned on" or "Activated by a timer", activation factor determination means to respond to a request to quickly start a different program depending on the activation factor 114 determines the cause of activation. Based on the determination result, the activation program selection unit 115 selects a program to be activated.

In step S307, the activation program selection unit 115 confirms whether or not the activation program selection table 154 exists. If the activation program selection table 154 exists, the activation program selection table 154 is loaded in step S308.
Here, the activation program selection table 154 is actually included in the initialization completion memory image stored in the initialization completion memory image storage area 140, and is loaded into the main memory 150 by loading the initialization completion memory image. It is expanded and exists on the main memory 105.

Subsequently, in step S309, the activation program selection unit 115 checks whether or not the activation program corresponding to the activation factor determined by the activation factor determination unit 114 is described in the activation program selection table 154. When it is confirmed that is described, this activation program is selected.
If the activation program corresponding to the activation factor is recorded in the activation program selection table 154, the activation program selection means 115 stores the running program information 202 in the OS data 151 in step S310, that is, the activation program to be activated, that is, The start program is corrected so as to correspond to the start factor recorded in the start program selection table 154.

Next, in step S311, the activation program selection unit 115 modifies the program management information 201 existing on the memory image so that the target activation program is in an execution state. Here, the program management information 201 is expanded on the main memory 150, and is information for the OS to manage the operation of each program.
When the above process ends, the process proceeds to step S312.

If the activation target program table 154 does not exist in step S307, or if the mobile program corresponding to the activation factor is not described in the activation target program table 154 in step S309, the process proceeds to step S312.
In step S312, the activation program selection unit 115 corrects the program execution address to the address of the activation program to be activated. Thus, the activation process ends.

  As described above, the present embodiment has the initialization completion memory image storage area 140 for storing the initialization completion memory image at the time when the initialization of the OS, middleware, and application is completed, and stores the initialization completion memory image. A memory image loading unit 113 for reading an initialization completion memory image from the area 140, an OS initialization process selection unit 111 for selecting whether to perform a memory image load or a normal initialization process, and an initialization completion memory image The startup program selection means 115 for selecting the program to be started first from among the initialization completed programs existing above is integrated into the OS initialization process, so that it is executed immediately after startup according to the startup factor. It is possible to switch programs.

As described above, according to the present embodiment, it is possible to reduce the time taken from the start to the start of the program by starting up using the initialization completion memory image.
In other words, the normal OS startup is performed after various initialization processes (OS core part, various I / O devices) inside the OS, and then each application program startup process. Can be used. On the other hand, in the present embodiment, a memory image in a state in which the above-described various initialization processes are completed is loaded into the main memory 150, and a memory image in a state in which the various initialization processes loaded into the main memory 150 at the time of startup are completed. Can be used immediately, so the startup time can be shortened.

In addition, it is possible to change the information of the program being executed by loading the memory image with the OS initialization process. Therefore, multiple programs to be started at high speed are set, and depending on the start condition (start factor) To select the program to be activated.
That is, by using the memory image loading unit 113, the activation factor determination unit 114, the activation program selection unit 115, and the activation program selection table 154, the activation process in a plurality of activation patterns can be performed by making it possible to select an activation target program according to conditions. High speed can be achieved.

Furthermore, by realizing high-speed activation of a plurality of programs to be activated from a single memory image, there is an effect that it is not necessary to have a plurality of initialization completion memory images in order to realize high-speed activation of a plurality of programs.
In the conventional method, in order to increase the startup speed of each program with a plurality of patterns, it is necessary to have a memory image for each pattern corresponding to each startup, but according to the present embodiment, this is not necessary. Disappear.
In addition, it is not necessary for the boot loader to provide a memory image for each pattern corresponding to each activation.

Embodiment 2. FIG.
The second embodiment will be described below with reference to the drawings.
FIG. 4 is a block diagram of the computer startup time shortening method of the present embodiment. The same reference numerals as those in FIG.
In FIG. 4, reference numeral 400 denotes a memory image creation determination means for determining whether or not to create a memory image. Reference numeral 410 denotes main memory analysis means for analyzing the data structure of the main memory 150. Here, the inside of the main memory 150 (memory) is basically divided into an area used by the OS itself, an area used exclusively by each program, a shared memory area, and the like. The data structure of the main memory 150 is managed by the OS.

Reference numeral 420 denotes memory image creation means for storing information in the main memory 150 in the initialization completion memory image storage area 140. Here, the information in the main memory 150 indicates information (data) existing in the main memory (memory), and the memory image creation means 420 creates a memory image and completes the initialization. Save in the memory image storage area 140.
Reference numeral 430 denotes memory image management information that summarizes the size and load address of the OS main body and the memory image for each program, 440 denotes memory image actual data divided for the OS main body and each program, and 450 denotes a memory image creation flag. .

Next, the creation / writing operation of the initialization completion memory image will be described with reference to the flowchart of FIG.
FIG. 5 is a flowchart showing a processing procedure for creating and writing an initialization completion memory image. Here, the same reference numerals as those in FIG. 3 indicate the same operations. In the present embodiment, the operations from step S305 to step S312 are the same as those in FIG. 3 of the first embodiment.
If a normal OS startup process is selected by the OS initialization processing selection unit 111 in step S302, the normal initialization unit 112 performs normal OS initialization processing in step S303, and each program initialization in step S304. Means 120 performs normal initialization of each program.

  Next, in step S500, the memory image creation determination unit 400 refers to the memory image creation flag 450, and determines whether or not to create an initialization completion memory image in step S501. Note that if the memory image creation flag 450 does not instruct the creation of a memory image, the activation process is terminated as it is. If memory image creation is instructed, the process proceeds to step S502.

In step S <b> 502, the main memory analysis unit 410 grasps a program existing on the main memory 150 and analyzes a use state of the OS main body and all the programs on the main memory 150, that is, a data structure of the main memory 150.
The main memory (memory) has a data structure such as a part used by each program, a part used by the OS for system management, and a part used by various drivers to control the device. The part used depends on the purpose. In step S502, the data structure of the main memory is analyzed.

  In step S503, first, information on the main memory 150 used by the OS main body is converted into a memory image by using the memory image creation means 420 and stored in the initialization completion memory image storage area 140. At this time, the data itself is stored in the memory image actual data 440, and the size, load address, and the like are recorded in the memory image management information 430.

Next, in step S504, step S505, and step S506, the main memory that each program uses for each program, with respect to all the activated (in use) programs grasped and analyzed by the main memory analysis unit 410. The information on the storage 150 is individually converted into a memory image using the memory image creation means 420 and stored in the initialization completion memory image storage area 140.
In step S507, the memory image creation means 420 updates the memory image creation flag 450 to set the memory image creation disapproval setting.
As a result, unless the memory image creation flag 450 is corrected again, the memory image is not created at the next normal activation.

  As described above, according to the present embodiment, when the application initialization is completed, the presence / absence of the initialization completion memory image creation instruction is determined. If the creation instruction is issued, the memory image creation determination unit that calls the memory image creation unit 420 is determined. When the memory image is created, the main memory analysis unit 410 analyzes the contents of the main memory and divides the OS use part and the use part for each program, and creates a memory image for each divided area. By having the memory image creating means 420, a memory image divided for each program is created.

As described above, according to the present embodiment, it is possible to save a memory image for each program. Therefore, by storing only the main storage area that is actually used, the size of the initialization completion memory image can be saved. Can be reduced.
This is because in an actual system, it is impossible to use up all the memory at the completion of initialization, unless it is intentionally done, and memory is consumed as the program runs. There are many cases. In other words, when the initialization is completed, the memory usage should be smaller than the actual memory size, and by saving only the part that is actually used as a memory image, the size of the memory can be made smaller than saving the whole memory. It is something that can be done.

Further, by self-creating the initialization completion memory image, the memory image can be recreated when the OS and the program are updated.
Here, the self-creation of the initialization completed memory image means that the memory image can be created by the computer alone, not by externally drawing out the memory image from another computer by a special method. It is.
If the OS or the program is corrected, the memory image is naturally changed. If the computer cannot modify the memory image alone as in this embodiment, there is a problem that when the OS or application program is modified, the memory image must also be modified from the outside.

Subsequently, in step S309, the activation program selection unit 115 checks whether or not an activation program corresponding to the activation factor detected by the activation factor determination unit 114 is described in the activation program selection table 154.

  When the activation program corresponding to the activation factor is recorded in the activation program selection table 154, the OS data memory image loading means 600 is stored in the memory image actual data 440 in the initialization completion memory image storage area 140 in step S701. The memory image of the OS data being loaded is loaded into the main memory 150.

  Next, in step 702, the startup program memory image loading means 601 stores the memory image of the program stored in the memory image actual data 440 in the initialization completed memory image storage area 140 (program 1 data in the memory image actual data 440, Only the memory image of the program to be activated is loaded into the main memory 150 from the program n data).

If the activation program selection table 154 does not exist in step S307, or if the activation program corresponding to the activation factor is not registered in the activation program selection table 154 in step S309, the OS data memory is determined in step S700.

In step S1700, the load target memory image state confirmation unit 1600 confirms the state of the OS data and the memory image management information 430 of the execution program. If there is no problem, the same processing as in FIG. 3 of the first embodiment is performed from step S310 to the end.
If a problem is found in the memory image in step S1700, the memory image load abnormality processing unit 1601 reads the abnormality processing designation table 1603 in step S1701 and reads a countermeasure for the abnormality detection program.

Next, in step S1702, the memory image load abnormality processing unit 1601 refers to the abnormality processing designation table 1603 and determines whether a countermeasure against the abnormality detection program, that is, degenerate activation is designated.
Here, when the reduced activation is not designated as the process for the program in which the abnormality is confirmed, that is, when the normal activation is designated, the memory image load abnormality processing means 1601 performs the normal activation process after step S303.

On the other hand, if reduced activation is specified in the abnormal process specification table 1603 in step S1702, that is, if a program to be started as the reduced mode is specified, the process proceeds to step S1703.
In step S <b> 1703, the degenerate operation start unit 1602 performs setting change so that the degenerate start program instructed in the abnormal process specification table 1603 is set as a start target program.
Thereafter, the processing procedure from step S310 to the end is the same as in FIG. 7 of the third embodiment.

  As described above, according to the present embodiment, it is possible to start in a degraded operation or a maintenance state by providing a mechanism for instructing another program to start with respect to a program in which a memory image check has occurred. Can do.
