Description

  The present invention relates to a system, a method, and a program for supporting the development of embedded software that operates in a system built in industrial equipment, home appliances, and the like, and more particularly to a technique for automatically setting the operation order between blocks in the embedded software.

  As is well known, in the development of embedded software, a block diagram (also referred to as a block diagram) is created as a design drawing related to computation. For example, when an embedded device to be developed executes addition and multiplication, blocks representing addition and multiplication are arranged from input to output, and the operation order is expressed by connecting the blocks with lines.

  A program is created based on the block diagram created here, and the created program is compiled using a dedicated compiler and incorporated into an actual machine to test the operation. For example, a program is created by an embedded software development support system disclosed in Patent Document 1.

  The embedded software development support system of Patent Document 1 includes an operation order automatic setting device and an operation order manual setting device as devices for setting the operation order of each block in a block diagram composed of a plurality of blocks. A program is generated by creating and compiling source code according to the calculation order set by both apparatuses, and an operation test is performed by an operation simulation apparatus.

  Based on FIG. 3, the automatic calculation order setting of Patent Document 1 will be described. FIG. 3A shows a block diagram of a single line. In this case, blocks are searched from the input side to the output side, and the calculation order is automatically set in one direction (arrow F direction) from the input block (i1) to the output block (o1).

  FIG. 3B shows a block diagram having a branch. In this case, the block with the higher priority on the output side is calculated first. The numbers in the figure indicate the numerical values of the priorities, and indicate that the blocks with a small numerical value have a high priority. Therefore, the calculation block A is calculated and output first, and then the calculation block B is calculated and output.

  Further, FIG. 3C shows a block diagram of multiple inputs. Also in this case, a block having a higher input priority is calculated first. Therefore, the calculation block B is calculated first and input to the calculation block C, and then the calculation block A is calculated and input to the calculation block C.

JP 2010-66847 A

  According to the embedded software development support system of Patent Document 1, when the calculation process shown in the block diagram does not use the previous calculation result, that is, when different calculations without connection between data are performed, the calculation order is a block. Depends on the order of placement.

  Therefore, even when the positions of already arranged blocks are exchanged, the predetermined calculation order is not changed. If it demonstrates based on FIG. 4, the calculation process result of the calculation block A shown to Fig.4 (a) will not be utilized for the calculation process of the calculation block B, and there is no connection with data in each calculation process, and it is different. It can be said to be an operation.

  In this case, as shown in FIG. 4B, a series of arithmetic processing “output from the input block (i1) through the arithmetic block A and output block (o1)” and “calculation from the input block (i2)” Even if the upper and lower positional relations of a series of operation processing blocks output from the output block (o2) via the block B are switched, the operation order determined at the time of the first block arrangement is not changed.

  As a result, the developer has to recreate the block diagram when changing the already determined operation order to a desired operation order. This is not efficient and may increase the burden on the developer.

  The present invention is made to solve such a conventional problem, and each block diagram can be changed to a desired calculation order without re-creating it when performing separate calculation processing without connection between data. The solution is to reduce the developer's effort.

  The embedded software development support system of the present invention includes a start block acquisition function unit that acquires all the blocks indicating the input of each block diagram, and a coordinate acquisition function that acquires coordinate information of each block acquired by the start block acquisition function unit And a coordinate comparison function unit that compares each coordinate information acquired by the coordinate acquisition function unit, and adds a block on the input side to the calculation order setting list based on the comparison result and a preset rule, and the calculation An operation order setting block acquisition function unit for extracting one block from the head of the order setting list, an operation order addition function unit for adding the block extracted by the operation block setting acquisition function unit to the operation order list, and the extracted block An output block addition function unit for adding the output side block to the calculation order setting list.

  The embedded software development support method of the present invention includes a start block acquisition step for acquiring all blocks indicating input of each block diagram, a coordinate acquisition step for acquiring coordinate information of each block acquired in the start block acquisition step, The coordinate comparison step of comparing each coordinate information acquired in the coordinate acquisition step, and adding the block on the input side to the calculation order setting list based on the result of the comparison and a preset rule, and the head of the calculation order setting list An operation order setting block acquisition step for extracting one block from the operation block, an operation order addition step for adding the block extracted in the operation block setting acquisition step to the operation order list, and an operation order setting for the output side block of the extracted block Adding an output block to the list.

  As the rule, it can be determined that the coordinate information is added to the calculation order setting list in the order of the coordinate information. The present invention may be a program that causes a computer to function as the software development support system.

  According to the present invention, each block diagram can be changed to a desired calculation order without re-creating it when performing separate calculation processing without connection between data. Can contribute to mitigation.

(A) is explanatory drawing which shows calculation order calculation before the position change of a block diagram, (b) is explanatory drawing which shows calculation order calculation after the position change of the block diagram of (a).

FIG. (A) is a figure which shows the case where a separate calculation without connection between data is performed with two block diagrams. (B) is a figure which shows the state which replaced each block diagram of (a).

  Hereinafter, an embedded software development support system according to an embodiment of the present invention will be described. As shown in FIG. 1, this software development support system is a device for setting the calculation order of each block in a block diagram (block diagram) composed of a plurality of blocks. And a setting device 18.

  An operation order is set by both the devices 10 and 18, a program is generated by source code generation and compilation in the program generation device 19 in accordance with the set operation order, and an operation test is performed by the operation simulation device 20.

  In addition, since each said apparatus 18-20 is the same as patent document 1, description is abbreviate | omitted. Here, the software development support system will be described focusing on the calculation order automatic setting device 10.

≪Configuration example≫
A configuration example of the calculation order automatic setting device 10 will be described with reference to FIG. The calculation order automatic setting device 10 is different from Patent Document 1 in that a function for determining the calculation order based on the coordinate information of the input block is added.

  Specifically, the calculation order setting device 10 is configured by a computer and includes normal hardware resources of the computer (for example, a main storage device such as a CPU, a RAM and a ROM, and an auxiliary storage device such as an SSD and an HDD).

  As a result of the cooperation of this hardware resource and software resource (OS, application, etc.), the calculation order automatic setting device 10 has a start block acquisition function unit 11, a coordinate acquisition function unit 12, a coordinate comparison function unit 13, and a calculation order setting. A block acquisition function unit 14, an operation order addition function unit 15, an output block addition function unit 16, a priority block addition function unit 17, an operation order setting list DB 21, and an operation order list DB 22 are mounted.

  Each of the functional units 11 to 17 and the DBs 21 and 22 may be mounted on the same computer, may be distributed on a plurality of computers, or may be mounted on the same computer as the devices 18 to 20. It may be implemented on a different computer. Each DB 21 and 22 is constructed in the storage device, and holds an operation order setting list and an operation order list.

  The start block acquisition function unit 11 acquires a block indicating the start of a series of arithmetic processing shown in each block diagram. For example, the input block represented in each block diagram is acquired.

  The coordinate acquisition function unit 12 acquires coordinate information (for example, coordinate position) of each block acquired by the start block acquisition function unit 11. That is, in the block diagram, coordinate information is set for each of an input block, a calculation block, an output block, each branch point, and the like, and the coordinate information of the set block is acquired.

  The coordinate comparison function unit 13 compares the coordinate information acquired by the coordinate acquisition function unit 12 and adds to the calculation order setting list of the DB 21 based on the comparison result and the preset rule as shown by the arrow H (description) ) Here, as an example of the rule, the order of the coordinate position, that is, the addition of the input side block is set so that the block with the upper coordinate position comes first.

  The calculation order setting block acquisition function unit 14 takes out one block from the top of the calculation order setting list of the DB 21 as indicated by an arrow I. The blocks taken out here are added to the calculation order list of the DB 22 by the calculation order addition function unit 15 as indicated by an arrow J. Thus, the blocks extracted from the head of the calculation order setting list for setting the calculation order are sequentially stored in the calculation order list of the DB 22.

  The output block addition function unit 15 adds the block on the output side of the extracted block to the calculation order setting list of the DB 21 as indicated by an arrow K. As a result, the block on the input side and the output side are stored in the calculation order setting list of the DB 21 so that the top coordinate information is the top.

  Note that the priority block addition function unit 17 executes the same processing as in Patent Document 1 when there are a plurality of blocks connected to the input block or when there are a plurality of blocks connected to the output side of the block.

<Example>
An embodiment using the calculation order automatic setting device 10 will be described with reference to FIG. Here, description will be given of the calculation order setting when the developer creates the block diagrams (α) and (β) of FIG.

  This block diagram (α) relates to a single line connection “output from the input block (i1) via the operation block A at the output block (o1)”. Further, the block diagram (β) relates to a single-line connection “output from the input block (i2) via the operation block B to the output block (o2)”. The created block diagrams (α) and (β) are stored in a database (not shown).

(1) Example 1
In the first embodiment, basic calculation order automatic setting processing for block diagrams (α) and (β) will be described. First, when processing is started by a developer's operation or the like, the start block acquisition function unit 11 acquires block diagrams (α) and (β) from the database, and further, block diagrams (α) and (β ), All the input blocks, that is, the input block (i1) and the input block (i2) are obtained. Both input blocks (i1) and (i2) acquired here are temporarily stored in the storage device or the like.

  Next, the coordinate acquisition function unit 12 acquires the coordinate positions of both input blocks (i1) and (i2), and then compares the acquired coordinate positions. In this case, the input block (i1) has a higher coordinate position than the input block (i2), and the order of addition (description order) to the calculation order setting list in the DB 21 is first.

  Therefore, the input side block is added so that the input block (i1) is at the head at the arrow H in FIG. At this time, the operation block A connected to the input block (i1) is added before the operation block B connected to the input block (i2).

  Then, the calculation order setting block acquisition function unit 14 extracts blocks in order from the top of the calculation order setting list of the DB 21. The extracted blocks are sequentially added to the calculation order list of the DB 22 by the calculation order addition function unit 15.

  At this time, the input side blocks are extracted from the calculation order setting list of the DB 21 in the order of “arithmetic block A → arithmetic block B” at the arrow I, and are added to the arithmetic order list of the DB 22 at the arrow J. They are added in the order of “calculation block B”.

  Further, the output side block of the block extracted by the calculation order setting block acquisition function unit 14 is added to the calculation order list setting list of the DB 22 by the output block addition function unit 16.

  As a result, the calculation block A becomes the calculation order “1”, the calculation block B becomes the calculation order “2”, and then the calculation order on the output side is determined by the priority block addition function unit 17 or the like. When the calculation order setting list in the DB 21 becomes empty, the calculation order automatic setting process ends.

(2) Example 2
In the second embodiment, resetting of the calculation order when the position of the block diagram (α) and the position of the block diagram (β) are swapped up and down will be described. At this time, since the block diagrams (α) and (β) perform different calculations that are not connected between data, according to Patent Document 1, the calculation order depends on the order in which the blocks are arranged.

  On the other hand, according to the calculation order automatic setting device 10, the calculation order is automatically reset in consideration of the change in the arrangement of the upside down. That is, although the calculation sequence automatically set in the first embodiment is “calculation block A → calculation block B”, the developer wants to reset the calculation block A before the calculation block B for some reason. There is a case.

  In this case, the developer displays the block diagrams (α) and (β) on the display, selects the block diagram (β), and further moves the block diagram (α) onto the block diagram (α). In accordance with the developer's operation, the calculation order automatic setting device 10 executes the calculation order automatic resetting process.

  If the details are described based on FIG. 2B, the coordinate position of the input blocks (i1) and (i2) is reacquired by the coordinate acquisition function unit 12. Here, since the upper and lower positions of the block diagrams (α) and (β) are interchanged, the coordinate position of the input block (i2) is above the input block (i1), and the DB 21 as shown by the arrow P, as shown in FIG. The calculation order setting list is rewritten.

  That is, since the description order of the input block (i2) in the calculation order setting list is first, the calculation order setting list is updated so that the input block (i2) is first at the arrow H in FIG. The input side block is described.

  Further, the calculation order setting block acquisition function unit 14 sequentially extracts blocks from the top of the calculation order setting list of the DB 21, and the extracted blocks are sequentially described in the calculation order list of the DB 22 by the calculation order addition function unit 15. Updated.

  At this time, the input side blocks are taken out from the calculation order setting list of the DB 21 in the order of “arithmetic block B → arithmetic block A” in the arrow I, and in the arithmetic order list of the DB 22 in the arrow J, “arithmetic block B → It is described in the order of “operation block A”.

  Further, the block on the output side of the block extracted by the calculation order setting block acquisition function unit 14 is described in the calculation order list setting list of the DB 21 by the output block addition function unit 16.

  As a result, the calculation block B is changed to the calculation order “1”, the calculation block A is changed to the calculation order “2”, and then the calculation order on the output side is determined by the priority block addition function unit 17 or the like. As in the first embodiment, when the calculation order setting list in the DB 21 becomes empty, the calculation order automatic resetting process is terminated.

  In this way, according to the software development support system provided with the calculation order automatic setting device 10, the calculation order is determined based on the coordinate position of the input block, so the direction from the input block to the output block indicated by the arrow F2 In addition, it is possible to set the calculation order according to the movement position of the block diagram indicated by the arrow F1.

  As a result, the calculation order can be freely changed simply by changing the arrangement of the already created block diagram. In particular, each block diagram can be automatically reset to a developer's desired calculation order without re-creating it, even when separate calculation processes without connection between data are performed. This improves efficiency and reduces developer effort.

  In addition, since the calculation order of the created block diagram can be freely changed, the creation order of the block diagram is not a decisive factor in determining the calculation order, and this can also reduce the burden on the developer. .

  In addition, this invention is not limited to the said embodiment, It can deform | transform and implement within the range described in each claim. For example, the present invention may be an embedded software development support program that causes a computer to function as each of the units 11 to 17, 21, and 22.

  According to this program, the processing contents of the first and second embodiments can be executed by a computer. This program can be distributed by being recorded on a recording medium such as a CD-ROM or a DVD-ROM, or can be distributed via a network.
