Description

The present invention relates to an automatic assembling program arrangement apparatus that creates a program by dividing the program into a plurality of blocks, and automatically arranges an assembling program in each block by combining modularized programs to create an assembling program. .

Due to technology, modularization is 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.

Conventional modularized programs combine modules when software called assembler or linker generates machine language programs. Instructions to the processing system such as the assembler must be described in the source program according to the grammar of the assembler.

ア Assemble programs used in specific fields, for example, programs for controlling the engine of a car, have different data and the like for each model, but the program configuration itself 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 assembling program automatic arrangement device which can easily arrange a modularized program automatically.

The present invention provides an automatic assembling program arrangement device that divides an assembling program to be created into a plurality of blocks, and arranges a module program created in advance for each block. Configuration data input means for arranging and inputting data describing a module program to be arranged for each block, and a module program created in advance and stored with an attribute for allocating and generating a memory area added A program storage unit; and an arrangement unit that reads module programs from the program storage unit in the arrangement order of the blocks in response to an input to the configuration data input unit, and allocates and arranges the module programs in a memory area according to the added attributes. Assemble program automatic placement device .

The present invention is also characterized in that the attribute includes that a memory area should be secured as a RAM.

According to the present invention, the modularized program is arranged according to the data input to the configuration data input means. An attribute for allocating a memory area and generating the module area is added to the module program stored in the program storage unit. The arranging means reads out the module program in the arrangement order of the blocks of the assembling program to be created, and allocates and holds the module program in the memory area in accordance with the attribute added to each module program. By storing a plurality of module programs in the program storage means in advance and changing the description of the module program in the data input to the configuration data input means, the module program to be combined with the assembling program to be created can be easily changed. can do.

According to the present invention, when allocating a memory area, an area to be secured as a RAM can be designated as an attribute of the module program. With this arrangement, the arranging means can collectively allocate the area of the RAM to the memory area, and in a computer device in which the memory elements are separately mounted on the RAM and the ROM, the machine generated from the assembling program is used. It is easy to execute a language program.

As described above, according to the present invention, an assembling program can be automatically arranged according to data input to the configuration data input means. By changing the data to the configuration data input means, the generated assembling program can be easily modified.

According to the present invention, since the RAM is allocated to the memory area and arranged, the RAM can be efficiently arranged in the memory area.

FIG. 1 shows a schematic configuration of an embodiment of the present invention. An engineering workstation (hereinafter, abbreviated as "EWS") 1 as an automatic assembling program arrangement device includes 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 in which program codes representing operations of a CPU and the like in a program to be created are arranged.

FIG. 2 shows the basic concept when creating the creation program 10 in accordance with the configuration data 13. The program 10 to be created is specified by the specification data 14, necessary data is extracted from a database 15 constructed in the program storage device 5 in 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 of 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 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.

Table 1 shows 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 “ABCDS-00-AR” have a corresponding 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 a data relation state in the process of generating the creation program 10 from the specification 4 based on 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 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. As the RAM, there are 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 “constant format” in the standard module 21 are collected in the creation module 24 as constant data. The “logic” in the standard module 21 is collected into the logic in the creation module 24. The 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.

(4) RAM allocation 26 is performed based on the contents of the RAM table 22, and the RAM area 6 of the creation program 10 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 creation module 24 creates the module layout 29 with reference to the arrangement-related information 18 and creates the program body area 9 in the creation program 10.

FIG. 5 shows a process of creating an assemble program according to this embodiment. In step a1, a specification is given, and creation of a program is started. 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.

At step a8, the program automatically arranged and created is assembled and translated into 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, the creation of the program is terminated in step a11. For each module, if a syntax error of the assembler is removed at the stage of module creation in step a3, it is not necessary to correct the syntax error in step a10. 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.

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

The $ RAM area is allocated to consecutive addresses of $ 00 to $ FF, but the area is divided into, for example, five. Such a division is particularly effective, for example, when a part of the RAM 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 a method of allocating RAMs to the RAM area divisions as shown in Table 3.
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 allocation is completed, it is determined in step b7 whether there is any other RAM that has not been allocated yet. If there is an unallocated RAM, the process returns to step b2. When the assignment of all the RAMs is completed, the assignment process ends in step b8.

ＲＡＭ 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.
