Description

  The present invention relates to a program arrangement method for automatically creating a program by combining programs created in advance for each module.

From the technology, modularization is performed in the assembly program creation.
The assembly program corresponds to the machine language of a computer and is generally quite long. If you divide the program into multiple blocks and check the operation for each module of an appropriate length, then combining each module will improve the development efficiency of the program and improve the reliability of the operation. .

Many conventional modularized programs are pre-registered in a library in the form of subroutines or macros and read from the main routine.

  In a conventional modularized program, software called an assembler or a linker combines modules when generating a machine language program. An instruction to a processing system such as an assembler needs to be described in a sentence of a source program according to a grammar such as an assembler.

  An assembly program used in a specific field, for example, a program for controlling an engine of an automobile, has different data for each model, but the program configuration itself is almost common. For this reason, it is efficient to prepare a plurality of modules for modules different for each model and select a module necessary for creating an entire assembly program. However, such module selection must be made in the body of the assembled program that describes the main routine. For this reason, it takes time and effort to create and modify a new program, and further automation is difficult.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a program arrangement method that can automatically arrange a modularized program without selecting it in the program text.

The present invention comprises a RAM and a ROM as memory elements, and is combined with a module program, which is a source program created in advance for each module, to be executed by a computer using the RAM and ROM as a memory area. When creating a module layout and a module layout to which a memory area attribute indicating which area of the memory area is to be allocated is added, and a module layout A program storage means for storing the arrangement related information used in the above, and an extraction means for extracting the necessary module program and the arrangement related information from the program storage means based on the specification data of the program to be created; Module program extracted by the extraction means A program body that is a program representing the operation of the program to be created as an attribute added to the module program; RAM, which is a variable capable of reading and writing data, is included, and for the module program whose attribute is the program body, the program generated by translating the module program is stored in the ROM. Arrangement is made so as to be arranged, and module programs are combined according to the layout of the module created based on the arrangement-related information, and for the module program whose attribute is RAM, the module program is translated Generated by The program is arranged method program and performs allocation so as to be disposed in RAM.

  According to the present invention, the module program stored in the program storage means can be operated by a computer having a RAM and a ROM as memory elements. It is created in advance with an attribute added to which memory area to be allocated and arranged. The program storage means also stores arrangement related information used when creating a module layout. The extraction unit extracts the necessary module program and the arrangement related information from the program storage unit based on the specification data of the program to be created. The placement means assigns the module program extracted by the extraction means to the memory area according to the added attribute and places it. 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 capable of reading and writing data. The arrangement means assigns a module program whose attribute is not a RAM such as a program main body to the ROM, and assigns it to the RAM if the attribute is RAM. Necessary module programs are extracted based on the specification data, and the memory areas of the module programs are also allocated. Therefore, even if the memory area is not selected in the main text of the program, it is automatically arranged in the ROM and RAM. be able to.

  As described above, according to the present invention, a necessary module program is extracted according to the specification data, and the extracted module program is automatically arranged on a computer having a RAM and a ROM as memory elements. You can create a program. If the specification data is changed, the generated program can be easily corrected.

FIG. 1 shows a schematic configuration of an embodiment of the present invention. An engineering workstation (hereinafter abbreviated as “EWS”) 1, which is an assembly program automatic arrangement device, has a program arrangement means 2 and a configuration data input means 3 realized by software.
The program placement unit 2 receives the contents of the specification 4 and the data from the program storage unit 5 realized by a hard disk or an optical disk device. In the program placement means 2, a creation program 10 including a RAM area 6, a map area 7, a common part area 8 and a program body 9 is generated according to the configuration data input to the configuration data input means 3.
The RAM area 6 is an area in which variables or constants capable of reading and writing data 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 program that can be used in common from a plurality of types of programs is described. The program main body 9 is an area where program codes representing operations of the CPU and the like in a program to be created are arranged.

  FIG. 2 shows a basic concept when the creation program 10 is created according to the configuration data 13. The program 10 to be created is instructed by the specification data 14, and necessary data is extracted from the 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 program is divided into 12 blocks.

  The contents of the creation program 10 in FIG. 2 are shown in Table 1 below.

  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 automatic placement apparatus is set.

  FIG. 3 shows the relationship between the block contents of the creation program 10 of FIG. 2 and the types of assignment attributes to the memory area. If the type is RAM, the RAM is allocated when the program is created. If the type is a map, map data is written. If the type is a common part, a pre-created common part is arranged. If the type is a program body, constant data is written and modules are arranged.

  An example of the configuration data 13 shown in FIG.

  Here, the fifth block “RAM area definition” corresponds to the ninth block “main routine”. Therefore, also in the reference file name, “ABCDS00AR.MOD” and “ABCCD-S-00-A-R” are in a correspondence relationship. “XYZS030BR.MOD” and “XYZ-S0-30-BR (1/3)” to “XYZ-S0-30-BR (3/3)” correspond to each other. “XYZ... R” indicates that the file is divided into three files.

  FIG. 4 shows the related state of data in the process of generating the creation program 10 from the specification 4 using the configuration data as 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 4, the specification extraction data 20 is extracted. In accordance with the “module name” of the specification document extraction data 20, a file with the same name is read from the module library 16 as the standard module 21. The arrangement related information 18 is also referred to from the “module name”. 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. There are types of RAM 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 as map data in the map table 23. The “constant value” of the specification extraction data 20 and the “constant format” in the standard module 21 are collected as constant data in the creation module 24. The “logic” in the standard module 21 is collected in the logic in the creation module 24. Logic represents the operation of the CPU. The common parts retrieved from the common parts 17 are collected as common parts 25 as common constants and general-purpose subroutines.

  Based on the contents of the RAM table 22, RAM allocation 26 is performed, and the RAM area 6 of the creation program 10 is generated. A map layout 27 is formed based on the map data in the map table 23, and a map area 7 in the creation program is generated. A common component layout 28 is created from the common component 25, and the common component area 8 in the creation program 10 is generated. From the creation module 24, a module layout 29 is created with reference to the arrangement related information 18, and the program body area 9 in the creation program 10 is generated.

  FIG. 5 shows the process of creating an assembly program according to this embodiment. In step a1, a specification is given and program creation is started. In step a2, data is extracted from the specifications. 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 it is an unregistered module, it is newly 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. In step a5, it is determined whether user input is necessary. If 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 machine language. When there is a grammatical error or the result of the test operation using the translated machine language, in step a9, it is determined whether the program needs to be corrected. When it is determined that correction is necessary, the configuration data is corrected in step a10, and the process returns to step a5. When it is determined in step a9 that no correction is necessary, the program creation is terminated in step a11. For individual modules, if a grammar error in the assembler is removed at the stage of module creation in step a3, the grammatical error need not be corrected in step a10. The correction in this case is, for example, a correction for changing control data when the engine is actually controlled. If a plurality of data are created as modules in advance, the program can be corrected by simply switching the designation.

  The RAM allocation 26 shown in FIG. 4 is performed for an area divided as shown in Table 3, for example.

  Although the RAM area is allocated to consecutive addresses of $ 00 to $ FF, the area is divided into, for example, five. Such a division is particularly effective when, for example, a part of the RAM area is backed up by a battery so that data is not volatilized. The allocation content patterns A to E each represent an attribute of the RAM area. Patterns B and C can be assigned to the second section and the fourth section.

FIG. 6 shows a method of allocating RAM to RAM area sections as shown in Table 3.
Allocation is started from step b1, and one RAM to be allocated is taken in step b2.
In step b3, it is determined whether the RAM has already been allocated in 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. When it is determined that the pattern is other than patterns B and C, the pattern is assigned to a predetermined category in step b5. When it is determined in step b4 that the patterns are B and C, in step b6, allocation is first performed from the second segment. If there is a vacancy in the second section, it is assigned to the second section. If there is no empty space in the second section, it is assigned to the fourth section.

  When the allocation is completed, it is determined in step b7 whether there is another RAM that has not been allocated yet. When there is an unallocated RAM, the process returns to step b2. When all the RAMs have been allocated, the allocation process ends at step b8.

  As described above, the RAMs can be continuously and efficiently allocated to the memories without overlapping. In this embodiment, the program to be created is divided into 12 blocks and the attributes of the memory area are divided into four types, but it goes without saying that other numbers may be used.
