Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic program arranging apparatus for automatically creating a program by combining programs created in advance for each module. 2. Description of the Related Art Conventionally, modularization has been performed in creating an assembling program. Assembled programs correspond to computer machine language and are generally quite long. Dividing the program into multiple blocks, checking the operation of each module of a suitable length, and then combining each module improves the program development efficiency and improves the operation reliability. . Conventional modularized programs are often registered in a library in advance in the form of subroutines or macros, and read out from a main routine. [0004] In a conventional modularized program, software called an assembler or a linker combines modules when generating a machine language program. Instructions to the processing system such as the assembler must be described in the source program according to the grammar of the assembler. An assembling program used in a specific field, for example, a program for controlling an engine of an automobile has different data and the like for each model, but the configuration itself of the program is almost common. For this reason, it is efficient to prepare a plurality of modules for different modules for each model, and to select a module necessary for creating an entire assembling program. However, the choice of such a module must be made in the body of the assembling program describing the main routine. For this reason, it takes time and effort to create or modify a new program, and it is difficult to further automate it. An object of the present invention is to provide an automatic program arrangement device which can automatically arrange a modularized program without selecting it in the text of the program. According to the present invention, a program to be created, which is operated by a computer having a RAM and a ROM as memory elements, is combined with a module program created in advance for each module. In the automatic program placement apparatus for generating, when creating a module program to which an attribute about which memory area is to be allocated and arranged in a memory area obtained by dividing the memory element area into a plurality of areas, and a module layout A storage means for storing the arrangement-related information used for, and an extraction means for extracting necessary module programs and arrangement-related information from the program storage means based on specification data of a program to be created, The module program extracted by the extracting means is Arranging means for allocating and allocating to the memory area in accordance with the added attribute, wherein the attribute added to the module program includes a program main body which is a program representing the operation of the program to be created, and data reading and writing And RAM, which is a possible variable,
The allocating means allocates, to a ROM, a module program whose attribute is a program main body in accordance with a layout of a module created based on the layout-related information, and allocates a module program whose attribute is a RAM to a RAM. An automatic program placement device characterized by performing assignment. According to the present invention, the module program stored in the program storage means has an R
In order to be operated by a computer having an AM and a ROM, each module program is created in advance with an attribute of which memory area of a RAM or a ROM provided as a memory element is allocated and arranged. Have been. The program storage means also stores arrangement-related information used when creating a module layout. The extracting means extracts necessary module programs and arrangement related information from the program storage means based on the specification data of the program to be created. The arranging means includes the module program extracted by the extracting means,
Allocate and allocate to the memory area according to the added attribute. The attributes added to the module program include a program body that is a program representing the operation of the program to be created and a RAM that is a variable from which data can be read and written. The arranging means stores the module program whose attribute is not RAM such as the program
OM, and if the attribute is RAM, it is assigned to RAM. The necessary module program is extracted based on the specification data, and the memory area of the module program is also allocated. Therefore, even if the memory area is not selected in the text of the program, the module program is automatically arranged in the ROM and the RAM. be able to. FIG. 1 shows a schematic configuration of an embodiment of the present invention. Engineering workstation (hereinafter abbreviated as "EWS") 1 which is an automatic program placement device
Has a program arrangement means 2 and a configuration data input means 3 realized by software. The contents of the specification 4 and data from the program storage means 5 realized by a hard disk, an optical disk device, or the like are input to the program arrangement means 2. The program arranging means 2 generates a creation program 10 including a RAM area 6, a map area 7, a common parts area 8 and a program body 9 according to the configuration data input to the configuration data input means 3. The RAM area 6 is an area where variables or constants from which data can be read and to which data can be written are arranged. The map area 7 is an area where map data for lookup is arranged. The common component area 8 is an area in which a relatively small-scale program that can be commonly used by a plurality of types of programs is described. The program body 9 is an area where program codes representing operations of the CPU and the like in the creation program 10 are arranged. FIG. 2 shows the basic concept when creating the creation program 10 in accordance with the configuration data 13. The creation program 10 is instructed by the specification data 14, and necessary data is extracted from a database 15 constructed in the program storage device 5 of FIG. Each data in the configuration data 13 indicates the configuration of each block when the creation program 10 is divided into a plurality of program blocks. In the example shown in FIG. 2, the creation program 10 is divided into twelve blocks. The contents of the creation program 10 shown in FIG. 2 are shown in Table 1 below. [Table 1] In Table 1, "user input" indicates that the program creator should input data from a keyboard or the like. "Arrangement" indicates that the memory area is rearranged.
“Data writing” indicates that there is data to be written in the map area 7 shown in FIG. "System setting"
Indicates that the present automatic arrangement device sets. FIG. 3 shows the relationship between the block contents of the creation program 10 of FIG. 2 and the types of attributes assigned to the memory area. If the type is RAM, the RAM is allocated when a program is created. If the type is map, map data is written. If the type is a common component, a common component created in advance is arranged. If the type is a program body, writing of constant data and module arrangement are performed. An example of the configuration data 13 shown in FIG. 2 is shown in Table 2 below. [Table 2] Here, the fifth block “RAM area definition” corresponds to the ninth block “main routine”. Therefore, even in the reference file name, “ABCDS00AR.MOD” and “ABCDS-S
"-00-AR" are in a corresponding relationship. Also, "XYZS0
30BR. MOD "and" XYZ-S0-30-BR "
(1/3) "to" XYZ-S0-30-BR (3 /
3) "corresponds. "XYZ ... R" indicates that the file is divided into three files. FIG. 4 shows a relation state of data in the process of generating the creation program 10 from the specification 4 based on the configuration data shown in Table 2. In the program storage unit 5, a module library 16, a common component 17, and arrangement-related information 18 are stored in advance. From the specification sheet 4, specification sheet extraction data 20 is extracted. According to the “module name” of the specification extraction data 20, a file having a matching name is read from the module library 16 as the standard module 21. The “module name” also refers to the arrangement-related information 18. The common component 17 is referred to according to the “model data” of the specification extraction data 20.
Data described in “RAM” specified in the standard module 21 is collected in the RAM table 22. R
AM includes types such as "flag" and "direct". The “flag” is used for storing bit data. Direct specifies how to access the memory. The “map value” in the specification extraction data 20 and the “map format” in the standard module 21 are collected in a map table 23 as map data. The "constant value" of the specification extraction data 20 and the standard module 21
The “constant format” therein is collected in the creation module 24 as constant data. “Logic” in the standard module 21 is collected into “logic” in the creation module 24. “Logic” indicates the operation of the CPU. Common parts 1
The common parts retrieved from 7 are collected as a common part 25 as a “common constant” or a “general-purpose subroutine”. Based on the contents of the RAM table 22, R
AM allocation 26 is performed, and the RAM of the
Region 6 is generated. The map layout 27 is formed based on the map data of the map table 23, and the map area 7 in the creation program is generated. The common component layout 28 is created from the common component 25, and the common component area 8 in the creation program 10 is created. The module layout 29 is created from the creation module 24 with reference to the arrangement-related information 18.
A program body area 9 is generated. FIG. 5 shows a process of creating a program according to this embodiment. In step a1, a specification is given,
Program creation starts. In step a2, data is extracted from the specification. In step a3, a module is created based on the specification data.
If the module is already registered in the module library 16 shown in FIG. If the module has not been registered, a new module is created. In step a4, configuration data as shown in Table 2 is created, and a program generation process is started. The blocks described in the configuration data are processed according to the description order of the block names. Data corresponding to “remarks” in Table 1 can be determined by using “.” Or less of “reference file name” in Table 2 as an identifier or the like. In step a5, it is determined whether a user input is necessary. If a user input is required, the data input in step a6 is taken. In the next step a7, automatic program placement is performed based on the configuration data. In step a8, the program automatically arranged and created is assembled and translated into a machine language. At step a9, it is determined whether or not the program needs to be corrected, based on the result of the grammatical error or the result of the test operation performed by using the translated machine language. When it is determined that correction is necessary, the configuration data is corrected in step a10, and the process returns to step a5. If it is determined in step a9 that no correction is necessary, step a11
To end program creation. For each module, if any syntax errors of the assembler are removed at the module creation stage in step a3, step a1
There is no need to correct grammatical errors at zero. The modification in this case is, for example, a modification that changes control data when the engine is actually controlled. If a plurality of data are created in advance as a module, the program can be modified only by switching the designation. The RAM allocation 26 in FIG.
Is performed for an area that is divided as follows. [Table 3] Although the RAM area is allocated to consecutive addresses of $ 00 to $ FF, the area is, for example, 5
It is divided into two. Such a division is, for example, RA
This is particularly effective when a part of the M area is backed up by a battery to prevent data from being volatilized. The patterns A to E of the assignment contents respectively represent the attributes of the RAM area. Patterns B and C can be assigned to the second section and the fourth section. FIG. 6 shows that the RAM areas are divided into R as shown in Table 3.
The method for allocating the AM will be described. The allocation is started from step b1, and in step b2, one RAM to be allocated is taken. At step b3, it is determined whether or not the RAM has already been allocated to another block. If a RAM having the same name has not been allocated, it is determined in step b4 whether the pattern is other than B or C. If it is determined that the pattern is other than the patterns B and C, it is assigned to a predetermined section in step b5.
When it is determined in Step b4 that the patterns are B and C, in Step b6, first, the assignment is performed from the second section. If there is a space in the second section, it is further assigned to the second section. If there is no empty space in the second section, it is assigned to the fourth section. When the assignment is completed, it is determined in step b7 whether or not there is any other unassigned RAM. If there is an unallocated RAM, step b2
Return to When the assignment of all the RAMs is completed, the assignment process ends in step b8. As described above, the RAM can be efficiently allocated to the memory continuously without overlapping. In this embodiment, the program to be created is divided into twelve blocks, and the attributes of the memory area are divided into four types. However, it is needless to say that other numbers may be used. As described above, according to the present invention, a necessary module program is extracted according to specification data,
Using the extracted module program as a memory element, R
A program can be created by automatically arranging the program in a computer having an AM and a ROM. If the specification data is changed, the generated program can be easily modified. Further, according to the present invention, it is possible to arrange the ROM and the RAM separately based on the attribute added to the module program, and to assemble the assigned program by the translation means. it can.
