Abstract

PURPOSE:To easily measure program performance by counting and displaying the number of executed instructions simultaneously with the program test. CONSTITUTION:When a program test command is applied from a keyboard 2 to a command analysis executing device 5 of a central processing unit CPU 1, a source statement successive executing device 6 is controlled by the device 5 to read and successively execute the program from a source statement 3. In this case, instructions whose execution is normally terminated are counted by an execution instruction counting device 7 and the counted value of the program performance measured value is displayed on display device 4 together with contents of the source statement, thus easily executing the program performance measurement.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program performance 811 fixed method, and particularly to a program performance measurement method suitable for measuring the dynamic performance of a program.

[Conventional technology]

One of the methods to evaluate the execution performance of a program.

There is a method to evaluate by measuring the number of executed instructions. Conventionally, to measure the dynamic performance of a program, the number of executed instructions was calculated by tracing the execution instruction address of each instruction, analyzing the results and the program loading position in memory.

[Problem that the invention seeks to solve]

In the conventional technology, not only is it necessary to incorporate a tracer or the like into a computer, but also it is necessary to calculate the loading position of the program in memory and analyze the trace result, which poses a problem that measurement cannot be easily performed.

An object of the present invention is to provide a user with measurement results of program execution performance at the same time as a program test.

[Means for solving problems]

The above object is achieved by measuring the execution performance of the program at the same time as testing the program, and sequentially displaying the measurement results.

[For production]

The source statement (performance test program) is stored on a floppy disk or the like.

Read, parse, and execute this source statement. At this time, if an instruction is normally executed, the executed instructions are counted and displayed one after another on a display such as a CRT. This allows the user to visually check the execution performance of the program at the same time as testing the program.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the program performance setting method of the present invention. In Figure 1, 1 is the central processing unit of the main body of the program performance measurement process, including a keyboard 2 for inputting commands for program testing, a hard disk for storing source statement (performance measurement test program) files, a floppy disk, etc. An external storage device 3 and a display 4 for displaying the contents of source statements and the number of executed instructions are connected.

The central processing unit 1 is functionally comprised of a command analysis/execution unit 5, a source statement sequential execution unit 6, an execution command counting unit 7, and a screen display control unit [8]. Of these, the execution command counting device 7 and the screen display control device 8 are the main parts of the present invention.

All source statements on the external storage device 3 are executed sequentially by the source statement sequential execution device 6. At this time, the instructions whose execution has been normally completed are counted by the execution instruction count group R7, and the count value is sequentially displayed on the display 4 together with the contents of the source statement under the control of the screen display control device 8. Commands for program testing, such as source statements to be executed, are input from the keyboard 2, and the command analysis/execution device 5 analyzes them and instructs the source statement sequential execution device 6.

FIG. 2 shows a processing flow of the central processing unit 1 in FIG. First, according to instructions from the command analysis/execution device 5, the source statement sequential execution device 6 reads a source statement from the floppy disk 3 (step 101), analyzes the read source statement, and executes the instruction word (step 102). At this time, it is determined whether or not the instruction word has been executed normally (step 200). If the instruction word has been executed normally, the executed instructions are counted by the executed instruction counting device 7 (step 104).
, the screen display control device 8 displays the execution command count value on the display 4 (step 105); if the execution is not successful, the read source statement is corrected (step 106), and then the processing from step 102 is carried out. repeat.

FIG. 3 shows the display screen of the display 4. In this example, the statement (instruction) being executed is displayed in reverse video as shown by a hatched area 202.

For statements that have already been executed, only the number column indicating the statement ID is displayed in reverse video, as indicated by a hatched area 203. Execution instruction count value.

It is displayed in reverse video at the position indicated by 201. This execution instruction count value is updated sequentially every time an instruction is executed.

〔Effect of the invention〕

According to the present invention, the person in charge can visually check the execution performance of the program at the same time as testing the program. It has the effect of significantly shortening the regular work time, and allows the development of programs with good performance by taking program execution performance into consideration.
