Abstract

PURPOSE:To ensure the effective improvement of programs by using a device which measures the working properties of programs, a device which analyzes the static characteristics of programs, and a device which produces a program source by improving the program working properties. CONSTITUTION:When an instruction is received from an input program memory 5 via a keyboard 1 for selection of an improved program, a program working analyzer 2 and a program characteristic analyzer 3 are actuated. The analyzer 2 analyzes the program working and records the executing frequency and the working time of each sentence into a memory 7. The analyzer 3 records a program procedure formation table and the program control structure into a memory 8. A program improving device 4 inputs a program through the memory 5 selects a program sentence having a high executing frequency out of programs and a group of program sentences based on the recorded contents of both memories 7 and 8 and records the improved programs into an output program memory 6. Thus the programs are effectively improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a program source optimization method, and is particularly applicable to program development or program modification.
This invention relates to a program source optimization method for improving efficiency of programs.

[Conventional technology]

Conventionally, in order to improve the performance of a program, the take obtained from a means of measuring the execution frequency of each statement that is a component of the program is manually analyzed, and the program is improved manually. A new programmer was required, and program improvement work was not efficient.

[Invention or problem to be solved]

The above-mentioned conventional program improvement work requires a great deal of time and effort from trained engineers, and due to manual intervention, errors may occur during program improvement, making it difficult to efficiently improve the program. It wasn't.

[Means to solve the problem]

The program source optimization method of the present invention includes a device that measures and records and registers the execution frequency of each statement that is a component of a program, a device that analyzes and records and registers the structure of the program and characteristics of the components, and the frequency of execution thereof. The system has a device for creating a program source that improves the operating performance of the program based on measurement records of the program and analysis records of the program characteristics.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows an embodiment of the invention. In FIG. 1, this embodiment uses a keyhole controller to input program storage device 5.
Give instructions to select an improved program from. Based on this instruction, the program behavior analysis device 2 and the program characteristic analysis device 3 operate.

The program operation analysis device 2 executes the execution operation of the program, analyzes the operation, and records the execution frequency of each statement of the program and the operation time of the statement in the storage device 7.

The program characteristic analysis device 3 stores the procedure configuration table and control structure, which are the program structure of the program, in a storage device 8.
to be recorded.

When the program operation analysis device 2 and the programmer 18 are recorded in the storage device 7 and the storage device 8 by the characteristic analysis device 3, the program improvement device 4 inputs the program from the input program storage device 5 and inputs the program into the storage device 7 and the storage device 8.
Select a program statement or a set of program statements that are frequently executed in the program from the records of the program, analyze the applicability of program acceleration techniques, and select the program statement or set of program statements if possible. Then, the applicability of the program acceleration technique is analyzed, and if possible, the program statement and the set of program statements are taken over and improved by the conversion method of the acceleration technique, and the results are recorded in the output program storage device 6. .

〔Effect of the invention〕

As explained above, the present invention improves the efficiency of program improvement by using a device for measuring the operational characteristics of a program, a device for analyzing static characteristics of a program, and a device for improving the operational performance of a program and creating a program source. It has the effect of increasing the number of people.
