Abstract

PURPOSE:To easily verify the error of arithmetic processing by providing a selecting switch means which stores data, which is left in an interface means and is related to the intermediate progress, and retrieval information data in a data preserving means in accordance with an external indication and a printing means which reads out and prints these data. CONSTITUTION:Intermediate data of operation is transferred from an arithmetic processing program 1 to an interface means 2 and is held this means 2. When a selecting switch means 4 is turned on by the external indication, data of the intermediate progress left in the interface means 2 is preserved in a data preserving means 3. Since data is preserved in the data preserving means 3 while rewriting old data, data does not overflow though being endless to exceed the capacity of the means 3. A printing means 5 prints data preserved in the data preserving means 3. Thus, the intermediate progress is outputted independently of a program by a generally usable method to easily verify the numerical calculation processing.

Description

[Detailed Description of the Invention] Industrial Application Fields The present invention is useful for verifying the validity of data and processing data when creating software/ware that performs numerical arithmetic processing in real time in a computer system. The present invention relates to a verification device for numerical calculation processing that is effective in discovering errors in numerical calculations.

BACKGROUND ART FIG. 3 is a conceptual diagram showing the flow of numerical calculation processing performed by a computer. In the first numerical calculation 1, for example, a plurality of data X1 to Xi are manually processed, and the calculation result is 01.
．． . As in the case of calculation processing, the calculation result of the calculation process is used as the input data for the next calculation process, and the data is used one after another in a chain, so that the calculation result Y is finally obtained.

For this reason, for example, if a 1 2 error is introduced in the first numerical calculation 1, the error causes a chain reaction that causes subsequent calculation results to be incorrect.

Conventionally, when the final calculation result Y is incorrect, in order to verify at what stage the error was introduced, intermediate calculation results are printed for each calculation process and kept as a record.

<Problem to be solved by the invention> However, recording all the results of such intermediate calculations not only requires a lot of man-hours to create a program for this purpose, but also causes problems when a large amount of calculation processing is to be performed. There is a problem that it is not easy to find the error part. Furthermore, in order to find errors after operation, it is necessary to temporarily stop the program running in real time and insert a process for printing or other progress output, which is very inconvenient.

The present invention has been made in view of these points, and when performing arithmetic processing, it is possible to output the intermediate progress using a method that can be generally used without depending on the program, and it is possible to verify the numerical calculation processing. The purpose is to provide a device that can be easily used.

〈Means for solving problems〉 FIG. 1 is a basic configuration block diagram of the present invention.

In the figure, 1 is an arithmetic processing program installed in the computer, and 2 is a structure that can be easily incorporated into the arithmetic processing program 1, and can retain data regarding the progress of the calculation and names defined in units that are easy to analyze. This is an interface means. 3 is a data storage means for storing intermediate progress data; 4 is a selection switch means for storing, in the data storage means 3, data related to the intermediate progress and name data left in the interface means 3 according to instructions from the outside; 5 is a storage means 3; This is a printing means that prints the data stored in the .

Effect〉 Each of the above-mentioned means operates as follows.

The interface means 2 receives data during the calculation from the calculation processing program and holds the data.

When the selection switch means 4 is turned on by an external instruction, the intermediate data left in the interface means 2 is stored in the data storage means 3. Even if the storage in data storage means 3 exceeds its capacity endlessly,
This is done while rewriting old data, so there will be no overflow. The printing means 5 is the data storage means 3
The data stored in the computer will be printed and submitted for analysis.

<Example> Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a structural block diagram showing one embodiment of the present invention. In the figure, the same parts as in FIG. 1 are denoted by the same reference numerals. The arithmetic processing program 1 is arbitrary software on the side that applies and utilizes the present invention, and represents an application program that performs a large amount of arithmetic processing. Here, for example, the i-th and i+1-th sub-software for arithmetic processing indicated by Al and A2 are included, and each sub-software A1 and A2 retains the input data and output data of the respective arithmetic processing. The necessary interface means 21, 22 are respectively coupled thereto. These interface means all operate as functions (subroutines) incorporated in the arithmetic processing program 1, and perform processing that only passes input data and output data.
The execution time of the arithmetic processing itself is rarely extended.

Reference numeral 23 represents progress data collection means for collecting data passed from each interface means 21 and 22. The selection switch means 4 is provided between the data collection means 23 and the data storage means 3, and executes or deactivates the data storage operation in response to an on/off instruction given by the storage/non-storage selection change program 40. I'm doing it.

Reference numeral 50 denotes a data printing execution program having a search function provided between the data storage means 3 and the printing device 5. The data printing execution program 50 retrieves intermediate progress data stored in the data storage means 3 while searching, and prints data corresponding to the printing device 5. It is configured to transfer data.

Reference numeral 6 denotes a CRT terminal having a keyboard 60, which functions as a machine interface, and instructs to start the storage/presence selection change program 40 and the data printing execution program 50.

The operation of the device constructed in this manner will be explained as follows.

Arithmetic processing program] Internal software AI, A
2 receives input data for each arithmetic process from the sub-software 1 of the previous arithmetic process via the interface means 21, and performs the arithmetic process according to a predetermined arithmetic expression set therein. At this time, the interface means 21.22
Input data and output data are left respectively.

When the results of the arithmetic processing are to be verified after the arithmetic processing is completed or during the arithmetic processing, the CRT terminal 6 instructs the activation of the selection change program 40 and the data printing execution program 50.

When the selection switch 4 is turned on in response to an instruction from the CRT terminal 6, the data collection means 23 controls each interface means 2.
]. , 22 are collected, search information such as calculation name, elapsed time, etc. is added to these data by {-1, and the data is transferred to the data storage means 3 and stored. Note that when the selection switch 4 is off, the collected data is discarded without doing anything.

The data storage means 3 stores the data transferred via the selection switch 4 so that it can be retrieved according to the search information.

When the data printing execution program 50 is started in response to an instruction from the CRT terminal 6, the data printing execution program 5
0 reads the data stored in the data storage means 3 according to the search information and transfers it to the printing device 5. The printing device 5 prints, for example, an operation name and
The manual data, output data, and elapsed time are formatted and printed.

Therefore, by examining the printed results, it is possible to easily know the progress of the calculation, and to verify the numerical calculation process.

Effects of the Invention> As described in detail above, according to the present invention, instructions from a CRT terminal can be applied to an arithmetic processing program without stopping its processing, regardless of whether it is being tested or running. , whether or not data is saved, and printed results of the progress of arithmetic processing can be obtained, making it possible to easily verify errors in arithmetic processing. Further, such verification is also performed after the completion of the calculation process. Therefore, there is an extremely practical effect that the number of man-hours required for creating an arithmetic processing program can be significantly reduced.
