[Industrial application field]

The present invention relates to an internal data format conversion processing method in a multi-system in which a plurality of systems can be combined to perform cooperative processing.

When the formats of data used for internal processing (referred to as internal data formats) are different in each system that makes up a multi-system capable of cooperative processing.

When a system attempts to process data in another system for cooperative processing, it is necessary to either convert the data format or prepare a processing program in the system that can directly process the data in the other system's internal data format. The present invention realizes a translation means that efficiently generates a processing program using the latter method.

[Conventional technology]

FIG. 4 shows a conventional example of a multi-system consisting of two systems that cooperate to perform processing.

In the figure, 41 is a system A having an arithmetic processing function, 42 is a system B having an input/output processing function, and 43 is a file in which data is stored.

System B takes out the data in the file 43, processes it, and if calculation is required at that time, requests system A to perform the calculation and returns the result. Such control can be achieved by, for example, when a program in system B calls a function, control is transferred to system A, and system A executes the function routine and returns the result.

In such cooperative processing between systems, if the internal data format of system B (file storage data format) and the internal data format of the data processed by system A's arithmetic processing functions are different, system A The data in System B cannot be directly handled due to the requested processing.

Differences in internal data formats include the back format and unpacked format for decimal digit data, and the M format and IEEE format for floating point data.

For example, if we look at floating point data in the M format and the
M format has a numerical range of IQ-72 to 1072, IEEE
The format can represent a numerical range from IQ-1e to 103s, and the precision is lower in the M format than in the IEEE format.

For example, in the conventional example shown in Figure 4, if system B's internal data format is IEEE format and system A's internal data format is M format, system B can request floating point arithmetic to system A. In order to 1 as the data format
The methods used were to perform bidirectional conversion between the M format and the IEEE format, or to provide system A with a program that could perform calculations directly in system B's internal data format.

[Problem to be solved by the invention]

Conventionally, in cooperative processing between multiple systems with different internal data formats, it is necessary to convert the internal data format when transferring data between systems, or to perform processing requested from other systems without converting the internal data format. to the requesting system.

It was necessary to have a processing program that could directly handle the internal data of the client's system.

However, with methods that convert internal data formats, for example, converting floating point data from IEEE format to M format, the accuracy of the data may deteriorate as a result of the conversion. If you try to use this method, you will need a translation means (compiler) to generate a processing program that can handle the internal data format of the target data, and if the system does not have such a translation means, had the inconvenience of having to create a dedicated translation means for each newly required internal data format.

SUMMARY OF THE INVENTION An object of the present invention is to provide a program translation means that can easily generate target programs in arbitrary different internal data formats on a relatively small scale.

[Means to solve the problem]

According to the present invention, the program translation means of at least one of the systems constituting the multi-system is a translation processing unit that generates a processing program having a certain internal data format determined by the own system as a target program. is the basic system, and the conversion processing unit that rewrites the part related to the internal data format of the generated target program into another internal data format is the secondary system.
It is composed of tiers.

FIG. 1 is a diagram showing the principle of the present invention.

Reference numeral 1 denotes a source program to be translated, which is used to perform cooperative processing in one system in a multi-system.

2 is a basic translation processing unit that translates the source program 1 according to one internal data format that is basic in its own system, and generates a target program.

3 is a first target program generated by the basic translation processing section 2, which can operate in the basic internal data format in local processing of its own system.

Reference numeral 4 denotes a conversion processing unit, which performs processing for converting the basic internal data format of the first target program 3 into another specified format.

Reference numeral 5 denotes conversion specification information, which provides information about the internal data format to be converted to the conversion processing unit 4.

Reference numeral 6 denotes a second target program resulting from conversion of the internal data format by the conversion processing unit 4 based on the conversion specification information 5.

[Effect]

In the present invention, a basic internal data format is selected for each system constituting a multi-system capable of cooperative processing, and the basic translation processing unit 2 shown in FIG. 1 is prepared in accordance with the selected internal data format. Also, information on the internal data format of other systems, which is required in the cooperative processing, is prepared as conversion specification information 5.

When each system performs local processing in its own system, the basic translation processing unit 2 translates the source program used for the processing, generates a first objective program 3, and performs the processing using its basic internal data format. can be executed.

In addition, in a system that processes data in different internal data formats of other systems when performing cooperative processing with other systems, the conversion processing unit 4 further converts the first objective program 3 into the internal data format of the other systems to be cooperated with. A secondary conversion process (post-processing) is performed using the conversion specification information 5 corresponding to , a second target program 6 having the target internal data format is generated, and the collaboration process is executed.

〔Example〕

FIG. 2 shows the configuration of a system according to an embodiment of the present invention.

In fig.

7.8 are systems A that each constitute a multi-system
and system B.

9 is a bus that connects each system.

10.18 is the compiler.

11.19 is the basic translation processing section.

12 is a conversion processing unit.

13.20 is a high-level language source.

14.21 is an assembly language assembler source I output as a target program from the basic translation processing unit 11.19.

15 is internal data format conversion specification information.

16 is an assembly language level assembler source (■) output from the conversion processing unit 12;

17.22 is a program execution section.

Reference numeral 23 indicates processing data whose processing is to be transferred from system B to system A in cooperative processing.

In this case, the internal data format of the basic translation processing unit 19 in system B matches the internal data format of the processed data 23, but does not match the internal data format of the basic translation processing unit 11 to the system.

For this reason, the specifications of the internal data format of the processing data 23 are set in the conversion specification information 15 of the system A.

■Convert the internal data format of the program's assembler source.

Next, the operation will be explained using a specific example.

In system A, the high-level language source 13 processes floating point data. The basic translation processing unit 11 is
Load high-level language source, 14 assembler source I
generate.

The basic translation processing unit 11 translates the floating-point data processing description into floating-point arithmetic instructions for system A, for example, in a manner that is most convenient for operating on the own system A (
In this case, the floating point arithmetic instructions determine the format of the floating point data).

Since the floating point arithmetic instructions of system A cannot directly handle the processing data 23, which is floating point data of system B, 14 assembler sources I are converted using the conversion processing unit 12 and conversion specification information 15. ,
Generate 16 assembler sources ■.

On the other hand, since the system B does not directly process the data on the system A side, the basic translation processing unit 19 performs processing using the assembler source I 21 generated by translating the high-level language source 20.

FIG. 3 shows the flow of conversion processing by the conversion processing unit 12.

Steps (1) to (2) in the figure will be explained in order.

■Check whether the assembler source I of system A ends. If it is the end, the conversion process is ended, and if it is not the end, the next step (■) is executed.

■: Read one line (one instruction) from assembler source I.

O: Identify whether the read target line (instruction) is related to the internal data format and detect the conversion target. If it is a conversion target, execute ■; otherwise, execute ■.

@: Convert the target line using the conversion specification information 15 in FIG. 2, write it to the assembler source ■, and return to ■.

■: Export the target line as is to the assembler source■,
Return to ■.

By processing all lines of the assembler source I in this manner, an assembler source (2) that processes the processing data 23 of the system B in the floating point data format is obtained.

〔Effect of the invention〕

According to the present invention, it is possible to generate target programs in any plurality of internal data formats using one translation means, so it is possible to reduce system costs, and as a result, it is possible to reduce the cost of the system. It is possible to realize cooperative processing.
