Abstract

PURPOSE:To attain the change of time counting sections by providing a register means for start and end points for measurement of the program performance, a means for substitution of a monitor interruption instruction, a time reading means, and a display means. CONSTITUTION:The start and end points of a measurement section are supplied from an input means 1 as the time counting points and registered to a register means 2. A start means 6 loads a program to be measured into a memory and a substituting means 3 substitutes the instructions of the registered start and end points for measurement of program performance for a monitor interruption instruction. An executing means 7 executes the monitor interruption instruction during execution of a program and a reading means 4 reads a time point and stores it into a monitor. Then the means 7 restarts the execution of the program. When the execution is through with the program, both start and end time points for measurement of the program performance are displayed by a display means 5 with a command input supplied from the means 1.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method for measuring the running performance of a program.

(Prior art) Conventionally, in this type of performance measurement, a measurement interval is set in advance in the target program, and a process to display the entire time at the performance start point and end point is embedded. This allows the time to be displayed at both ends of the measurement interval during running. The test was carried out by calculating the elapsed time.

(Problems to be Solved by the Invention) The conventional measurement method described above has the drawback that it is necessary to embed processing for reading the time in advance in the target program, and the entire measurement interval cannot be easily changed. Another disadvantage is that extra processing must be performed even when no measurement is performed.

An object of the present invention is to register the performance start point and end point on a program in a monitor, and when the program is loaded, replace the instructions of the registered performance start point and end point with a monitor interrupt instruction, and The above-mentioned drawbacks are eliminated by storing the time at which the program was activated by an instruction and displaying the stored time, and the system is configured to measure time by generating monitor interrupts at the start and end points during execution. The purpose of this invention is to provide a method for measuring program performance.

(Means for solving the problem) The program performance measurement method according to the present invention includes a registration means,
It is configured to include a replacing means, a reading means, and a display means.

The registration means is for registering the start point and end point of program performance measurement in the monitor.

The replacement means is for replacing the registered commands at the start and end points of program performance measurement with monitor interrupt commands at the time of program loading.

The start-up means is activated by a monitor interrupt command and is for reading and storing the time.

The display means is for displaying the stored continuation time.

(Example) Next, the present invention will be explained in detail with reference to the drawings.

Referring to FIG. 1, one embodiment of the present invention includes an input means 1, a registration means 2, a replacement means 3, a succession means 4, a display means S, a starting means 6, an execution means 7, Clock 8 and C
It is composed of an RT display 9.

Referring to FIG. 2, the operation of the registration means 2 shown in FIG. 1 consists of a measurement section information input step 21 and a time measurement storage step 22.

Referring to FIG. 3, the operations of the replacement means 3 shown in FIG. 1 include a time survivability determination step 31, an instruction replacement step 32,
and execution means activation step 33.

Referring to FIG. 4, the operation of the reading means 4 shown in FIG. 1 consists of a time reading step 41, a time storing step 42, and an execution means starting step 43.

Referring to FIG. 5, the operation of the display means 5 shown in FIG. 1 consists of a performance calculation step 51 and a performance display step 52.

Next, the operation of the present invention will be explained with reference to FIGS. 1 to 5.

First, the measurer inputs a command from the input means 1 to operate the registration means 2. The registration means 2 inputs the start point and end point of the measurement section as measurement time points according to the measurement section information input step 21, and performs registration according to the measurement time entry 1 and step 22. Next, the measurer inputs all program hypermotion commands through the input means 1 to operate the starting means 6. The activation means 6 loads a measurement program onto the memory and operates the repurchase means 3. The replacement means 3 first determines whether or not the counted time registered by the registration means 3 exists in the segment loaded according to the time counted existence determination step 31. If the counting time exists, the instruction at the counting time is replaced with a monitor interrupt instruction according to the instruction replacement step 32, and then the execution means 7 is operated in the execution means starting step 34. If there is no measurement point,
The execution means 7 is activated according to the execution means starting step 34.
make it work. Thereafter, the program is executed by the execution means 7. When the monitor interrupt instruction replaced by the replacement means 3 is executed during program execution, the reading means 4 is activated. In escape means 4, time reading step 4
1, the time is stored in the monitor according to time storage step 42. Thereafter, the execution means 7 is operated according to the execution means starting step 43, and the execution of the program is resumed. By repeating this operation, the times at the start and end points of performance measurement are stored when the program ends.

Finally, the measurer inputs all commands from the input means 1 and operates the display means 5. The display means 5 displays the performance /! according to the performance calculation step 51. 4. Display performance Step 5
Display the performance on the CRT display according to 2.

Note that the performance calculation method in the performance calculation step 51 is
This will be explained with reference to the figures. As shown in FIG. 6(a), since there is a monitor processing time associated with reading the time, accurate performance cannot be obtained only from the difference in time read at the start and end points of performance measurement. Therefore, as shown in FIG. 6(b), the monitor processing time is measured by executing two monitor interrupt instructions side by side, and the program performance = (TB- TA) (ta
+tb') and the city correction, accurate performance can be obtained.

(Effects of the Invention) As explained above, the present invention has the effect that by providing the monitor with a performance measurement function, there is no need to provide a performance measurement processing function for each program, and the measurement period can be determined before program execution. Another advantage is that it can be set arbitrarily.
