Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to computer support for software development.
In particular, the present invention relates to a program execution display method suitable for improving program efficiency.

[Conventional technology]

The display power formula in conventional program performance evaluation technology includes:
There are methods that count the number of executions of statements used to calibrate a program, and display the number of executions or a graph representing the number of executions on each line of the source program in a contrasting manner, and procedures for the execution time of each year's continuation/function in the software.・There was a method to display it in contrast to a function. However, it has been difficult to intuitively understand the execution efficiency of the above techniques by comparing them with the program structure.

[Problem that the invention aims to solve]

The above-mentioned conventional technology expresses the performance of each part of the program using numerical data or a graph corresponding to the numerical values in a source program or the like that does not express the program structure. Therefore, it has been difficult to intuitively grasp which part of the program structure is reducing execution efficiency. Furthermore, if execution efficiency is expressed numerically or graphically, a new dimension must be displayed, making the display screen complicated.

The purpose of the present invention is to
By compactly representing the parts that consume a lot of CPU time, etc. using visual color differentiation, it is possible to intuitively understand the parts of the program structure that consume a lot of CPU time, etc. ,Thereby,
The purpose is to make it possible to quickly and without error determine the most effective measures for improving efficiency, such as which part of the program to improve the algorithm or which part to combine input/output instructions into one.

[Means for solving problems]

The above purpose is to determine the CP TJ consumption time, elapsed time, and number of executions of each element during execution of the target program.

Or, a means for calculating the ratio of any of them to the whole, and a part or parts that consume a large amount of CP TJ waiting time or elapsed time based on the CPU consumption time information, elapsed time information, or execution number information of each element in the program. This can be achieved by creating a software graphic such as a known PAD diagram in which parts that are frequently executed are distinguished by one color, and by providing means for compactly displaying it on a display or printer during or after execution.

[Effect]

CPU consumption time and elapsed time in software diagrams such as PAD diagrams that express the program structure.

Based on the execution function or the ratio of any of them to the whole, each element is distinguished in color and presented to the user in a compact manner during or after execution.

This allows the user to intuitively understand the parts of the program structure that consume a lot of CPU time.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

The following embodiment will be described using a well-known PAD diagram as a graphic display format expressing a program structure.

FIG. 1 is a functional configuration diagram of a program performance evaluation display system that implements an embodiment of the present invention.

In FIG. 1, 1 is a part that generates an internal representation format of a PAD diagram from a source program. 2 is the generated PAD
This is the internal representation format of the diagram. An example of the target source program is shown in FIG. 2, and a P/AD diagram generated from it is shown in FIG.

3 in Figure 1 is a part that generates interrupts at regular time intervals. 4 is a part that interprets and executes the internal representation format of the PAD diagram, and accepts interrupts from 3. When the interrupt is accepted, the identifier of the box in the PAD diagram corresponding to the current execution position is passed to 5. For example, in Figure 3, “x medium=
If an interrupt occurs during the execution of ``x'', the execution is interrupted and the value in box 50 is passed to 5.

5 in Figure 1 is in the interrupt count table of 6 for each interrupt reception.
Increase the interrupt occurrence frequency information corresponding to the corresponding box by one. An example of the interrupt count table is shown in FIG.

7 in FIG. 1 adds all the interrupt counts in 6 at the end of execution, and stores the value obtained by dividing the interrupt count for each box by the total interrupt count as a percentage in the relative value information corresponding to each node. FIG. 5 shows a diagram of relative values.

8 of the figure determines the color of each node of the PAD diagram according to the calculated relative value. For example, 0% or more and less than 10%, 10%
If we assign different colors to 20% or more and 20% or more, in the PAD diagram in Figure 3, 20, 60, 70%
The box of 30°40.50 is a dark color.

9 in FIG. 1 displays the internal representation format of the PAD diagram 2 in color on the display. FIG. 6 shows a display example of the performance evaluation results for the source program shown in FIG. 2.

In this embodiment, it is possible to intuitively understand which part of the program structure is consuming CPU time.

It is also possible to display the results as a textual representation of the source program. A functional configuration diagram according to this embodiment is shown in FIG. In this example, there is no need to generate a PAD diagram,
At step 10, the program is interpreted and executed. The information passed from 10 to 5 becomes the line number of the statement in the program source. The ID column of the box in the interrupt count table 6 is the line number of the statement. 11, the source program is displayed in color. The results of the performance evaluation are shown in Figure 8.

In the two embodiments described above, the percentage of CPU consumption time was determined by interrupting the program being executed. In the following example, the ratio of CPU consumption time is determined based on information on the execution time for each predetermined operation and program execution.

Figure 9 shows the functional configuration of the system. 12 stores an operation execution time table that holds execution times of various operations. 13 calculates the execution time of the box in the PAD diagram of 2 from this table, and creates a box execution time table of 14.

4 executes one box in the PAD diagram during execution and then passes the identifier of the executed box to 15. In step 15, the execution number information corresponding to the corresponding box in the accumulated execution time table in step 16 is increased by one.

At the end of execution, 17 multiplies the number of executions in 16 and the execution time in 14 to find the cumulative execution time for each box, and calculates 1
Record it in the cumulative execution time information in 6. Next, the total execution time is determined, and the value obtained by dividing the cumulative execution time for each box by the total execution time is recorded as a percentage in the relative value information corresponding to the container.

An example of the integrated execution time table is shown in FIG.

The displayed results will be similar to those shown in FIG.

If a rough comparison of the CPU consumption time is sufficient, the number of times the box is executed is calculated using the functional configuration example of FIG. 9 excluding 12.13.14, and the rough execution time is calculated and displayed from this be able to.

In addition, in program structure diagrams such as PAD diagrams that display performance evaluation results, a function has been added to display information on execution time and number of executions in boxes corresponding to the branches of the program structure diagram in addition to the boxes corresponding to the root. Other implementation methods are also possible.

FIG. 11 shows a functional configuration diagram of an embodiment of this system. Specify a box in the PAD diagram using a command. This command is parsed by 18 in FIG. 11 and passed to 19.

In step 19, referring to the PAD diagram, a 2o display interrupt count display is created in which the information of boxes corresponding to branches and leaves of the specified box is added to the information of the specified box, and the information of boxes corresponding to branches and leaves is deleted. A colored PAD diagram based on 20 is displayed. As an example, FIG. 12 shows a display result in which the information of boxes 40.50 and 30 in FIG. 6 are summarized.

This embodiment makes it easy to understand the execution efficiency of a subset of the program structure.

Further, in the above-described embodiment, all colors to be displayed are determined by relative values, but they may also be determined by absolute values of values such as CPU consumption time. In the functional configuration diagram of FIG. 1, except for the part 7 in which relative values are calculated, the display color in color information editing in 8 is determined based on the absolute value of the CPU consumption time value.

Further, in all the embodiments described above, the performance evaluation results are displayed after the execution of the program is completed, but it is also possible to display the CPU consumption time, etc. in real time while the program is being executed. A system configuration diagram of this embodiment is shown in FIG.

In FIG. 13, after executing one box in the PAD diagram during execution, the identifier of the executed box is passed to 21.

In 21, the execution time corresponding to the corresponding box in the box execution time table of 14 is referred to, and the cumulative execution time corresponding to 16 is increased by that amount. Based on this information, color information is edited in step 8 and displayed in step 9. The currently running box is also displayed by wearing a special color. After displaying, the process returns to 4 and returns to PA
The next box in diagram D is interpreted.

According to this embodiment, performance evaluation results can be displayed immediately upon program execution. Additionally, the user can know when the CPU is consumed.

Furthermore, in FIG. 9, by setting the contents of 12 to be information on the elapsed time of each calculation, it is possible to display in color the part that consumes a large amount of elapsed time.

According to this embodiment, parts such as the I10 instruction that do not consume CPU time but consume a large amount of elapsed time can be displayed.

〔Effect of the invention〕

As explained above, according to the present invention, the program structure
By visually representing the parts that consume a lot of CPU time, etc., it becomes easier to recognize and understand them, which has the effect of improving the efficiency of work to improve the efficiency of the program.
