Abstract

PURPOSE:To execute initialization of a device in an early stage by loading a subroutine for bringing a nonvolatile memory subsequently to loading of an OS when a power source is turned on, etc., and initializing the system initializing information by referring to the nonvolatile memory. CONSTITUTION:A main storage 2 is a readable/writable memory for loading, etc., an OS (operating system) 2-1, a resident subroutine 2-2 for bringing a nonvolatile memory 1 to access, an initial application 2-3 for executing the initialization of a device 3, and a non-resident nonvolatile memory control program 2-4 for bringing the nonvolatile memory 1 to access, and setting, updating the system information. When a power source is turned on, etc., the subroutine 2-2 and the initial application 2-3 are loaded subsequently to loading of the OS 2-1, and this initial application 2-3 executes a request to the subroutine 2-2 and refers to the nonvolatile memory 1, and initializes the system initializing information to the device. In such a way, the system initializing information is set to the device in an early stage, and it can be raised quickly.

Description

[Detailed Description of the Invention] CI! Required] Regarding the system initialization information early setting method that refers to non-volatile memory and quickly sets system initialization The purpose of this is to initialize the system initialization information to the device by referring to the non-volatile memory, and to initialize the device quickly.It also stores various system setting information and retains it even when the power is turned off. It is equipped with a non-volatile memory that holds contents and a subroutine that accesses this non-volatile memory, and when the power is turned on, etc., the subroutine that accesses the non-volatile memory and the initial application are loaded following the loading of the OS, and the initial application is loaded. The application requests a subroutine to refer to the non-volatile memory and configure the system to initialize the system initialization information to the device at an early stage. [Industrial Application Field] The present invention relates to a system initialization information early setting method that quickly sets system initialization information by referring to a nonvolatile memory.

[Prior art and problems to be solved by the invention] A line control device that controls a line stores various data (for example, destination, session, etc.) in a non-volatile memory that does not lose data even if the power is turned off. Please refer to if necessary,
It is being updated and processed. However, conventionally, when the nonvolatile memory control program that accesses the nonvolatile memory is not loaded when the power is first turned on, the initial zero setting of various devices cannot be performed, and until the nonvolatile memory control program is loaded. There was a problem that the initialization process could not be performed quickly because the system was forced to wait. The present invention loads a subroutine that accesses nonvolatile memory after loading the OS when the power is turned on, and thereby refers to the nonvolatile memory to initialize system initialization information in the device, thereby initializing the device. The aim is to carry out this as early as possible. [Means for solving the problem] Means for solving the problem will be explained with reference to FIG.

In FIG. 1, a non-volatile memory 1 is a memory that stores various setting information of the system and retains its contents even when the power is turned off. Subroutine 2-2 is a subroutine that accesses nonvolatile memory 1. The initial application 2-3 requests the subroutine 2-2 to refer to the nonvolatile memory 1 and initialize initialization information in the device. [Function] As shown in FIG.
2-1, subroutine 2-2 that accesses non-volatile memory l and initial application 2-3 are loaded, and this initial application 2-3 requests subroutine 2-2 to refer to non-volatile memory l. However, the system initialization information is initialized to the device at an early stage.

Therefore, when the power is turned on, subroutine 2-2 is loaded following loading of 052-1, and system initialization information is initialized in the device by referring to the non-volatile memo +71. System initialization information (for example, information on destinations, sessions, etc.) can be set early on the line controller (line controller), allowing for quick startup. [Embodiment] Next, the structure and operation of an embodiment of the present invention will be explained in detail using FIGS. 1 and 2. Figure l shows the WS
The main memory 2 is an OS (operating system) 2-1, a resident subroutine 2-2 that accesses the non-volatile memory according to this embodiment, and an initial system of a device 3. Initial APL to configure
(Initial application) 2-3. This is a readable and writable memory that loads a non-resident non-volatile memory control program 2-4 that accesses the non-volatile memory 1 under operating conditions and sets and updates system information. The device 3 is a device, program, etc. that refers to the nonvolatile memory 1 and sets system initialization information (for example, destination, session 3, etc.) when the power is turned on. The program file 4 is a file provided in an external storage device, and stores programs such as the OS. The display 5 displays data, status, and the like. Here, it is displayed that the system is "starting up" when the power is turned on.

Next, the operation of the configuration shown in FIG. 1 will be explained in detail in accordance with the order shown in the flowchart of FIG.

In Figure 2, ■ loads the OS. This loads the OS (operating system, kernel)>2-1 from the program file 4 onto the main memory 2 in FIG. .0 loads the subroutine.This is done by loading the subroutine 2-2 from the program file 4 and making it resident after loading 032-1 onto the main memory 2 in Figure 1. 2-2, the non-volatile memory l can always be referenced quickly, and system initialization information can be quickly set in the device. ■ Loads the initial APL. Load the initial APL2-3 onto the main memory 2.As a specific example, we will explain the operation when the line system initialization APL is loaded using @ or [phase].■ is the line system initialization application. Load this into the main memory 2 in Figure 1.
Load the line system initialization application as APL2-3. ■This line initialization application is a non-volatile memo I7 1
Refer to. This is done by the line system initialization application requesting the subroutine 2-2 loaded with @ and referring to the system initialization information (for example, information such as destination, session, etc.) of the line system device 3 in the nonvolatile memory l. ．． [Phase] performs initial settings of the device. This requests the subroutine 2-2 in [phase] to refer to the non-volatile memory 1 and initialize system initialization information such as destination and session in the line control device. By performing the above [phase] to @ processing, the destination, session, etc. of the line system control device are initialized and set to an operational state. At this time, after loading the OS at ■, subroutine 2-2 and initial AP are loaded.
By loading L2-3 and initializing system initialization information in the device by referring to non-volatile memory l, 'a
It is possible to quickly set up system initialization information (for example, information on destination, session, etc.) in rt<for example, line control device Z) and to quickly start up the system.

■Loads a non-volatile memory-based program.
This program mainly includes a non-resident non-volatile memory control program 24 for setting and updating system information in the non-volatile memory 1 during normal operation. Load it onto i2 as shown. Then, the nonvolatile memory control program 2-4 is requested to set and update the contents (system setting information) of the nonvolatile memory l. The series of loading processes is completed by the above steps, and operation is started.

In the figure, 1 is a nonvolatile memory that stores system initialization information, 2 is a main memory, 2-1 is an OS (operating system), 2-2 is a subroutine, and 2-3 is an initial APL.
(initial application), 2-4 represents a nonvolatile memory control program, 3 represents a device, 4 represents a program file, and 5 represents a display. [Effects of the Invention] As explained above, according to the present invention, after loading 032-1 when the power is turned on, the resident subroutine 2-
2 and thereby refer to the non-volatile memory and initialize the system initialization information to the device, so the system initialization information (for example, Information such as destinations and sessions can be set early and startup can be done quickly.
