Abstract

PURPOSE:To easily identify the length of task time by converting the scale of the task length based upon a changed time scale and successively plotting the lengths of respective tasks correspondingly to respective tasks. CONSTITUTION:A program is read out and stored and the time lengths of respective tasks are successively plotted on a screen correspondingly to respective tasks based upon the time L of a selected task and a previously set time scale T and then a time for changing the time scale T is inputted. The time scale T is changed based upon the changing time, the scale of the length of the task time L is converted based upon the changed time scale T and the lengths of respective tasks are successively plotted on the screen correspondingly to respective tasks. Consequently, the time lengths of respective tasks can simply be identified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for displaying the length of time of a program task, and in particular to scale conversion thereof.

[Prior art] When evaluating the performance of a program, the time for each task is calculated and the time on the time axis of the display area of the screen that displays the time for that task is set in advance (hereinafter referred to as time scale). Then, based on that timescale, the calculated task time length was displayed in correspondence with the task.

Then, the operator identifies tasks that take a long time and, in some cases, performs processing such as shortening the program of tasks that take a long time in order to improve the performance of the program.

[Problems to be Solved by the Invention] In the conventional task time scale conversion display method as described above, the time scale is fixed, so the length of the task time is displayed based on the time scale. Therefore, there was a problem that it was difficult to understand the length of time for a task.

The present invention has been made to solve this problem, and instead of fixing the time scale and displaying the length of the task, the time scale can be arbitrarily changed and the length of the task displayed. To obtain a task time scale conversion display method that allows the length of time to be drawn according to the time scale and easily identify the length of a task time.

[Means for Solving the Problems] The task time scale conversion display method according to the present invention includes an analysis and collection process in which a program is read and stored, each task is analyzed, and the tasks and task times are stored in a storage means. a selection processing step of selecting a task to be drawn from among the tasks after analysis and collection processing, and extracting the selected task and the time of the task from the storage means, and extracting the selected task and the time of the task from the storage means, Based on the timescale in which
an editing display processing step of sequentially drawing the time length of each task on the screen in correspondence with each task; an input step of inputting the time to change the time scale; A time scale change process that changes the time scale, and a scale conversion process that scales the length of the task based on the changed time scale, and sequentially draws the length of each task on the screen in correspondence with each task. It consists of a process.

[Operation] In the present invention, after reading and storing a program in the analysis and collection processing step, analyzing each task, and storing the task and its time in the storage means, each of the tasks stored in the selection processing step is , select the task to be drawn.

Then, the task selected in the editing display processing step and the time of the task are extracted from the storage means, and the length of time of each task is displayed on the screen in correspondence with each task based on a preset time scale. Draw sequentially.

Next, input the time to change the time scale in the input process, change the time scale based on the input change time in the time scale change process, and change the task in the scale conversion process based on the changed time scale. The length of time is converted to a scale and the length of each task is drawn on the screen sequentially in correspondence with each task.

The flowchart is a flowchart illustrating editing and displaying, and FIG. 2c is a flowchart illustrating RUN time graph drawing.

FIG. 2 is a block diagram that specifically uses the present invention, and this drawing will be explained in correspondence with FIG. 1.

In the figure, (l> is the floppy that stores the program to be evaluated, (2) is the first floppy that stores the analysis/collection processing program, (3) is the second floppy that stores nothing, and ( 4> is the third floppy disk that stores the editing/display processing program and the RUN task transition graph program.

In this case, start up the main unit's personal computer, insert the floppy disk (1) containing the program to be evaluated into the main unit's first floppy unit (not shown), and insert the program into the main unit's processor (8). FDD controller (
The first floppy disk (1) in which the program to be evaluated after being read and stored in the memory (9) via the

) is inserted into the first floppy unit of the main unit, and the second floppy unit (not shown) stores nothing, for example. Assume that the second floppy disk (3) is inserted into the second floppy unit of the main body.

Then, the processor (6) on the main body uses its trap function to execute the process described below based on the analysis/collection process program stored in the first floppy disk (2).

The address of the task of the program to be evaluated that is in the RUN state is detected and stored in the second floppy disk (3) (S
IOI). Then, the processor (6) on the main body side determines whether the termination system service command has been output to the kernel by the analysis/collection processing program (310).
3).

Next, if it is determined that the system service command is not output, the task is identified from the detected address and the length of execution time is calculated (5104), and the second floppy (3)
Store in.

Then, the control is transferred to step 5IOI, and in order to put the next task in the RUN state, the corresponding test data is read and the processes from step 5Lot to step 9104 are repeated.
Trace information such as the address of the task and the length of execution time is stored as collected data in a second floppy (3) inserted into the second floppy unit.

In this case, it is assumed that the test data for evaluation has already been examined and stored in the main body's memory (9>), and that the addresses and identifications of all tasks have been determined.

Next, if the processor (6) on the main body side determines in step 5102 that a system service command has been output, the processing of this analysis/collection program ends.

Then, in order to pass the collected data shown in FIG. 1(b) to the editing/display routine, the first floppy disk (2) inserted into the first floppy unit is removed.

Next, the editing/display processing program shown in FIG. 1(b) is stored in the first floppy unit.1. Insert the third floppy disk (4).

Then, the processor (6) on the main body side executes the editing/collection process shown in FIG. 1(b), which will be explained below, based on the program.

The processor on the main body side (6> searches for the first unit of the trace information of the collected data stored in the second floppy unit 5201) and extracts the task name to be displayed (S203).

Next, the first collected data is set in the buffer (initial value set for trace data) (S205).

Next, parameters for drawing the graph are set (initial set for graph drawing) (S207).

Next, the screen is edited (8209), and the screen is displayed on the display (7) of the main body (S211).

Then, a graph of the RUN time is drawn (hereinafter referred to as a RUN task deviation graph) (8213). This will be explained below using a graph displayed on the screen.

FIG. 3 is a diagram illustrating drawing of a graph of RUN time.

In the figure, (11) is the name of a task in the program to be evaluated, (12) is the RUN time of the task, and (14) is the name of the program to be evaluated.

In this case, it is assumed that all tasks are shown in one minute by default.

Next, display guidance (advance, execution, display range, graph scale, end) as shown in Figure 3 on the display (7> screen 8215), and use the keyboard (8215) to select the displayed guidance. If a key is pressed, the processor (6) reads the key information (S
217), e.g. forward (S219), execution (S221)
, display range specification <8223), graph scale specification (S22
5), the process shown in FIG. 1(b) is executed according to the end (S227).

Next, suppose that it is difficult to see the task RUN time on the graph scale of 1 minute, and if the graph scale of guidance is specified, control is transferred to step 5215 and the guidance described above is displayed.

Then, if execution is selected, control is transferred to step 52.
05, and in step 5213, the RUN time graph drawing process of FIG. 1(c), which will be explained below, is executed. Also,
In explaining this process, the RUN time graph drawing process in FIG. 1(e) will be explained using the diagrams described below.

FIG. 4 is a conceptual diagram illustrating a method of setting a line representing the task RUN time.

In the figure, (15) is the area of the screen that displays the RUN task transition graph, and (T) is the length of the area (15) that displays the RUN task transition graph. The scale is selected and changes depending on the input time. This time is hereinafter referred to as reference scale T.

(L) is the time “ni” at the end of the first task to be displayed.
area (1) to display the RUN task transition graph from
5) shows the time corresponding to the length to the end.

First, as shown in FIG. 1(C), read the input reference scale T and set the time in a register etc. (9301
). In addition, this reference scale T can be set arbitrarily by the user.
It can be set to seconds, T milliseconds, T microseconds, etc.

Next, the task to be displayed first (hereinafter referred to as the first task)
8303), and the time t until the task (hereinafter referred to as the start time of the current task) is read from the second floppy disk (3>) and set (8303).

Then, the start time of the next task (or the end time t of the current task) is read and set (8305).

n+1 Next, (tnil-tn) is subtracted from the reference scale T, the value is stored in the second floppy disk (3> 5307), and the length corresponding to that time is set as L (8311).

That is, let L be the length from the end time t of the first task to the right edge of the n+1 screen. Further, if the number of dots on the screen corresponding to T is R (S313), then the following formula % Formula % Next, from this formula, calculate the task length (hereinafter referred to as task length) 8315), A line of length is drawn from the left end of the area (15) where the RUN task transition graph is displayed in correspondence with the task to be displayed (Sa17). Then, it is determined whether there is a next task, and if there is, the next leading task is read and set (8321), control is transferred to step 5305 described above, and the next task is drawn.

Therefore, when the value of the reference scale T is changed, the length of L also changes, and the range in which the graph is displayed changes, making it possible to enlarge a portion of the graph or reduce the entire graph.

This graph will be explained below.

This is an enlarged view of a portion of the graph in the figure, showing that the operator can easily identify tasks with long RUN times.

[Effects of the Invention] As described above, according to the present invention, a program is read and stored, and the time of each task is determined in correspondence with each task based on a preset time scale. After sequentially drawing the length of the task on the screen, enter the time to change the timescale, change the timescale based on the changed time, and scale the task's time length based on the changed timescale. Since the length of each task is drawn sequentially on the screen in correspondence with each task, the effect of easily identifying the length of the task time is achieved.
