Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a system construction apparatus and a system construction method, and more particularly to a system construction apparatus and a system construction method improved to enable high-speed and flexible processing with a single tool.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, systems designed using a CAD (Computer Aided Design) tool are roughly classified into the following two types of implementation modes. That is, the first mode of realization is generally called a fixed-type program, and converts a design result into a program described in a predetermined program language (for example, C ++ language). This mode of implementation generally allows high-speed processing, depending on the language employed. However, when it is desired to change the system settings, there is a disadvantage that the entire system must be corrected again by the CAD tool and converted again.
[0003]
On the other hand, the second mode of implementation is generally called a variable program, and outputs a design result as a data file for an execution program separately prepared in advance. In this embodiment, the execution program reads and analyzes the data file to reproduce the design result therein.
In this case, the setting can be changed without re-conversion by replacing the data file.However, since the execution program needs to be created for general use, the program size becomes large, and the execution speed becomes slow. There was a disadvantage of becoming.
[0004]
[Problems to be solved by the invention]
Conventionally, a system construction apparatus such as a CAD tool usually provides only one of a fixed program and a variable program. You had to choose a tool depending on which one you wanted to focus on.
[0005]
On the other hand, in order to enable the above two forms of implementation for the same system, two types of tools that can create each of a fixed program and a variable program had to be prepared. . Moreover, in this case, data compatibility between different tools is often not guaranteed, so that a design work is required for each tool.
[0006]
In addition, there are the following problems as a CAD tool for creating a variable program. That is, in the variable program, as described above, the execution program reads the design result as a data file, but the format of the data file read by this program differs from the format of the file used by the CAD tool itself when designing the program. Was. Therefore, the data file read by the execution program cannot be created or modified using a CAD tool for program design, and a dedicated tool is required.
[0007]
For example, when a fuzzy inference system or the like is made by a CAD tool, a method is used in which rules are made variable, and a rule part is created later by using a special tool.
However, in this case, as a file structure when a system is created or saved by the CAD tool, a format suitable for the CAD tool is used. On the other hand, after the system is completed, a file structure of a variable portion created by a dedicated tool is used. As a result, a format suitable for the dedicated tool was used.
[0008]
The reason is that many operations are required to build a system with a CAD tool, and a file structure suitable for such many processes is used. It is because high-speed and operability are required to correct and complement the format, and a format specialized for each program is easier to use.
[0009]
As described above, two types of tools must be prepared in order to make the above-mentioned two realization modes possible in the conventional system construction apparatus, and the file structure is different for each tool. Could not be shared, and the versatility as a CAD tool was poor.
[0010]
SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-described problems of the related art, and an object of the present invention is to provide a system construction apparatus and a system construction method capable of performing high-speed and flexible processing with a single tool.

On the other hand, when there is a high possibility that the setting is changed after the mounting, a variable unit capable of changing the setting after the mounting is generated according to a user's instruction, and a variable program incorporating the variable unit can be output. This makes it possible to selectively output both the fixed program and the variable program with a single tool. In addition, since the user can freely specify the variable setting portion of the system to be designed, it is possible to obtain a conversion program having an appropriate configuration according to the possibility of changing the system after mounting.

According to the system construction apparatus according to the second aspect and the system construction method according to the sixth aspect having the above-described configuration, all or a part of the design result of the design target system is converted into design information in a predetermined format. Since the design information can be recorded on the recording medium and the design information can be read and reproduced as appropriate, the information recorded on the recording medium by another tool can be used when constructing the system.
[0014]

Predetermined design information can be read from a recording medium recorded as design information in accordance with a user's instruction, and reproduced on a variable program.
Thus, even when the setting is changed after mounting, the data processed by the program can be changed only by rewriting the file without changing the program itself.
[0016]

In addition, since the same system construction device can also supplement the variable part of the variable program, both the construction of the program and the correction / supplement can be performed by one device.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
Each function of the embodiment described below is realized by predetermined software controlling a computer and peripheral devices. In this specification, the invention and the embodiment are referred to as each function and each processing. In the description, a virtual circuit block such as “-means” corresponding to “. Therefore, each hardware element and each software element do not correspond one-to-one to each block.
[0019]
[1. First Embodiment]
[1-1. Constitution]
FIG. 1 is a functional block diagram illustrating a configuration of the system construction device 1 according to the first embodiment. That is, in FIG. 1, reference numeral 2 denotes a user interface unit, which includes means necessary for a user to design a system, for example, a display device such as a CRT display and an input device such as a keyboard.
The system construction apparatus 1 is configured to exchange information with a user via the user interface unit 2, and a designation of a “fixed program generation mode” or a “variable program generation mode”, which will be described later, This is performed via the user interface unit 2.
[0020]
Next, when the user designs a desired system via the user interface unit 2, the data processing unit 3 analyzes information input by the user and executes processing such as processing of the input design information. Then, the processing result is stored in the data storage unit 4 as system design data (SDD).
Further, the data processing unit 3 reads out the system design data stored in the data storage unit 4 and responds to a request from the user interface unit 2 to each unit (the user interface unit 2, the storage unit 5, reproducing means 6, fixed type program converting means 7, and variable type program generating means 8).
[0021]
The storage unit 5 outputs the system design data read from the data storage unit 4 to a design result file 9 in a predetermined format.
On the other hand, the reproducing means 6 reads out the system design data recorded in the design result file 9 in a predetermined format and reproduces it in the data storage unit 4.
[0022]
The fixed program conversion means 7 has a function of converting the system design data read from the data storage unit 4 into a predetermined program language, and when the fixed program generation mode is designated, All of the system design data is converted into a source code, and the conversion result is output to the outside of the system construction device 1 as a fixed program 10.
On the other hand, when the variable program generation mode is specified, only the portion designated by the user to be a variable program is replaced with a description indicating that the setting is variable, and the other portions are sourced in a predetermined programming language. It is converted into a code and output to the variable program generation means 8.
[0023]
Next, the variable program generation means 8 generates, as a file reading section, a source code having an instruction to read and analyze a predetermined file for a portion designated by the user as a variable program, The output is combined with the output of the means 7 and output as a variable program 11 outside the system construction apparatus 1.
[0024]
[1-2. Action]
The system construction apparatus of the present embodiment having the above-described configuration operates as described below.
Here, the system S to be created by the user is composed of four subsystems S1, S21, S22 and S23 as shown in FIG. 2 (A), of which S21, S22 and S23 Represents a single set of functions. Note that there is no clear distinction between the above “system” and “subsystem”, both of which receive input from the outside, execute predetermined processing from this input and the internal setting conditions, Outputs the processing result.
[0025]
[1-2-1. System configuration and design]
As described above, in the system S shown in FIG. 2A, the part including the subsystems S21, S22, and S23 represents one integrated function as a whole. Can be considered. That is, as shown in FIG. 2B, the system S includes subsystems S1 and S2, and the subsystem S2 has a hierarchical structure and stores subsystems S21, S22, and S23. You can also. In this case, the hierarchy of the subsystems S1 and S2 is called "level 1", and the hierarchy of the subsystems S21, S22, and S23 is called "level 2".
[0026]
In the system construction device 1 of the present embodiment, the system S can be designed in either of the formats shown in FIGS. 2A and 2B. In the system construction apparatus 1 having a GUI (graphical user interface), an independent window can be provided for each hierarchy of the system to be designed.
Here, it is assumed that the system is designed in the format shown in FIG.
[0027]
[1-2-2. Saving design results]
When a system is constructed using this apparatus, the design data created during the system construction is stored in the design result file 9 by the storage unit 5 in a predetermined format. At this time, the following information is described in each design result file 9.
(1) Subsystem connection definition: Connection relationship between subsystems defined in the same hierarchy (signal flow)
(2) Each subsystem internal definition: Internal setting information for each subsystem defined in the same hierarchy
There are the following three types of descriptions of internal settings used in this (2) subsystem internal definition.
(A) Recursive description... When a subsystem is made up of a group of other subsystems like the subsystem S2 in FIG. 2A, the subsystem connection definition and each Subsystem internal definitions can be employed.
(B) Detailed description of function: type of processing function uniquely given to the subsystem and setting conditions necessary for executing the processing function are described.
(C) Hierarchical information description... When the file itself has a hierarchical structure and its detailed definition is made in another file as in the subsystem S2 in FIG. 2B, the location of the file is described. .
[0028]
When the system S is designed as shown in FIG. 2B, the design result files 9 are generated by the number of layers included in the system S as shown in FIG. 2C. That is, the design result of the system S is stored in the two design result files “defle1” and “deffile2”. It should be noted that level 1 corresponds to "defle1", and level 2 corresponds to "defle2".
[0029]
Here, the design results of the system S stored in the two design result files (defile1, difffile2) shown in FIG. 2C will be described. That is, defle1 (level 1) describes a subsystem connection definition representing a signal flow of input → S1 → S2 → output and internal settings of the subsystems S1 and S2. In this case, the hierarchical information description is made as the subsystem S2 definition, and the location of the design result file "deffile2" in which the detailed design information of the subsystem S2 is described is shown.
On the other hand, define2 (level 2) describes a subsystem connection definition indicating a signal flow of input → (S21, S22, S23) → output, and internal settings of each of the subsystems S21, S22, S23.
[0030]
[1-2-3. Reproduction of design result]
When resuming system construction or generating a program from a completed system, the system construction apparatus 1 receives a command from a user to read design information of the system S, and performs design via the reproduction means 6. By reading and analyzing the result files “deffile1” and “deffile2”, the design results can be reproduced in the data storage unit 4 in the system construction apparatus 1.
[0031]
[1-2-4. Conversion of design results to source code]
In order to implement the function of the system S designed on the system construction apparatus 1 in a target environment, it is necessary to convert system design data into a processing program. In this case, the system construction device 1 of the present embodiment has two modes for converting a design result into a source code. That is, the first mode is a fixed type program generation mode, and the second mode is a variable type program generation mode. These two modes are configured so that the user can specify them via the user interface unit 2.
Here, the result of conversion into the processing program indicates a source code in a predetermined program language (for example, C ++ language), but the same applies to other formats, for example, executable binary code.
[0032]
[A. Generate Fixed Program]
If the design result of the system S is reliable and the possibility of changing the setting after mounting is low, the user selects the fixed program generation mode for the system construction apparatus 1 via the user interface unit 2. The data processing unit 3 designates the entire system S in response thereto and activates the fixed program conversion means 7, converts all the design results of the system S into source code, and obtains the fixed program 10. Further, the user gives the conversion result to a separately prepared compiler or the like to re-convert the conversion result into an executable format, and implements the conversion in a target environment.
FIG. 3 shows an image after the conversion by the fixed-type program conversion means 7.
[0033]
[B. Generating a variable program]
On the other hand, when there is a high possibility that the setting is changed after the system S is mounted, the user selects the variable-type program generation mode and converts the design result into the source code. That is, the user designates a set of subsystems that are desired to be variable after mounting via the user interface unit 2, and then selects the variable program generation mode.
[0034]
For example, assume that the user wants to make the subsystem S2 variable. In this case, the data processing unit 3 activates the fixed program conversion means 7 by designating that the subsystem S2 is variable. The fixed-type program conversion means 7 outputs the source code of the fixed-type program to the variable-type program generation means 8, replacing only the part of the subsystem S2 with a description indicating that the setting is variable.
On the other hand, the data processing unit 3 activates the variable program generation means 8 by designating the subsystem S2. The variable-type program generating means 8 generates a source code having a function of reading and analyzing the design result file “deffile2” of the subsystem S2 as a file reading unit, synthesizes the source code with the output of the fixed-type program converting means 7, and The program 11 is output.
[0035]
In the present embodiment, the file reading unit of the variable program 11 is configured by incorporating the source program of the reproducing means 6 of the system construction apparatus 1 at a predetermined position of the variable program.
In addition, when the setting variable portion is specified, a part of the system to be designed can be specified, and when the system to be designed has a hierarchical structure, it can be performed for each hierarchy.
FIG. 4 shows an image of the variable program 11 output by the variable program generating means 8.
[0036]
[1-3. effect]
According to the system construction apparatus 1 of the present embodiment, it is possible to selectively output both fixed programs and variable programs with a single tool.
In addition, since the user can freely specify the variable setting portion of the system to be designed, it is possible to obtain a conversion program having an appropriate configuration according to the possibility of changing the system after mounting.
Further, since the setting variable portion is only instructed to read a file, the data processed by the program can be changed only by rewriting the file without changing the program itself.
[0037]
Further, since the file reading unit incorporated in the variable-type program has the same function as the reproducing unit 6 provided in the system construction apparatus 1, the definition of the subsystem S2 is defined by the file "deffile2" which is the design result file 9 of the system construction apparatus 1. Can be used as is. As a result, even after the variable program is implemented in the target environment, unless the definition in defle1 (that is, the definition of level 1) changes, the subsystem S2 (that is, in level 2) on the system construction apparatus 1 does not change. The design can be freely changed, and by reading the changed file, the design can be changed without re-conversion.
[0038]
[2. Other Embodiments]
The present invention is not limited to the embodiments described above, and the following aspects can be considered.
That is, in the above embodiment, the design result file 9 handled by the system construction apparatus 1 is used as it is as the definition file read by the variable program 11, but the present invention is not limited to this. A format definition file may be adopted. However, in this case, it is necessary that the reproducing means 6 in the system construction apparatus 1 and the file reading unit in the variable program 11 be functionally equivalent but have different processing. As a result, it is possible to prevent the specification of the variable setting part of the system from depending on the hierarchical structure of the system designed by the system construction apparatus 1.
[0039]
Further, in the above embodiment, the variable program generation means 8 incorporates the source program of the reproduction means 6 into the variable program 11, but the reproduction means 6 is realized as a library, and the system construction apparatus 1 and the variable This may be configured to be linked from both of the type programs 11. In this case, the source program of the reproducing means 6 becomes unnecessary.
[0040]
Further, it is also possible to make a plurality of portions of the program variable and then, when a portion that can be fixed is created, fix only that portion. In this case, since the file for changing the program and the file for the CAD tool have the same format, the file created when the completed program has been corrected or supplemented is read from the CAD tool side, and is read by the CAD tool. By combining it with the contents of another design result storage file used, the design results obtained by taking in the contents modified / supplemented by the program can be converted again from the CAD tool into the program.
[0041]
Further, the variable program generation means 8 may be configured to generate both the fixed part and the variable part of the program. In this case, the synthesizing process with the output from the fixed type program conversion means 7 becomes unnecessary.
[0042]
The processing according to the system construction method of the present invention is realized by a computer program controlling a computer, and this program is provided by being recorded on a recording medium.
[0043]
【The invention's effect】
As described above, according to the present invention, it is possible to provide a system construction apparatus, a system construction method, and a medium recording a system construction program, which enable high-speed and flexible processing with a single tool.
