Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data processing method, and particularly to a data processing method in a data processing system having an environment in which a plurality of programs can operate simultaneously.

[Conventional technology]

In this type of conventional data processing method, when data to be processed is input to one data processing program from multiple other data output destination programs among programs running simultaneously in parallel, First, other data to be processed is accumulated in a temporary storage buffer such as a data waiting queue or a buffer until the arithmetic processing of the data to be processed inputted to the data processing program is completed.

In addition, a table is generated for each input data to be processed, and the table is used to temporarily store or recall the information necessary to perform calculations on each data to be processed, thereby processing multiple data in a time-sharing manner. A method for doing so is also known.

[Problem to be solved by the invention]

Among the above conventional techniques, in the former, only one data to be processed is processed by the data processing program at a time, so other programs that require the processed data output from the processing program are You have to wait until the required processed data is processed and output by the processing program,
There was a problem that redundant time was required. For this reason,
In systems where data such as communication programs are exchanged frequently, this results in a significant reduction in processing speed.

In addition, in the latter of the above-mentioned conventional techniques, multiple data can be processed simultaneously, albeit in a time-division manner,
Although it is possible to reduce the data waiting time of a program that requires processed data, on the other hand, the mechanism within the data processing program becomes complex, which increases the burden on the program developer. was there.

The present invention has been made in view of the above circumstances, and its purpose is to solve the above-mentioned problems in the conventional technology and shorten the redundant time mentioned above without increasing the development load on program developers. The object of the present invention is to provide a data processing method that can improve the processing speed of the entire system.

[Means to solve the problem]

An object of the present invention is to interoperate between a plurality of programs running simultaneously in a system having a central processing unit having an environment in which a plurality of programs can operate simultaneously, an external storage device capable of storing a large amount of programs, and an input/output means. When transferring data, if input of data to be processed from a plurality of other programs to one program (data processing program) among the plurality of programs running simultaneously in parallel occurs almost simultaneously, The same program as the data processing program is generated for the number of input data to be processed, the generated data processing program performs arithmetic processing on the input data to be processed, and the processed data that is the result is output. This is later achieved by a data processing method characterized by erasing the generated data processing program.

[Effect]

In the data processing method according to the present invention, even when data to be processed is input to a certain layer from multiple layers at the same time, the control program immediately generates as many data as the number of data inputs. is,
Since arithmetic processing is performed on the input data to be processed, the time required to complete the arithmetic processing on the input data to be processed is significantly reduced.

Furthermore, the above-mentioned step of generating data processing programs for the number of input data to be processed, and the step of actually performing arithmetic processing on the input data to be processed, outputting the results, and then erasing the program. Using a separate program also has the effect of reducing the load on the program developer.

Embodiments of the present invention will be described in detail below with reference to the drawings. In the embodiments described below, the present invention will be described using OS I

This example shows a case in which the system is applied to a communication system compliant with ction).

However, it goes without saying that the present invention is not limited to this.

FIG. 2 is a diagram showing the configuration of a unit system, in which 2-2 is a central processing unit (CPU) that has an environment in which multiple programs can run simultaneously, 2-3 is a keyboard input device,

FIG. 3 is a diagram showing the overall system configuration of this embodiment, and each system includes the CPU 2-2. Keyboard input device 2-31 Display device 2-4. A system comprising an external storage device 2-5 is connected to a communication network 2-6 via a communication control unit (CCU) 2-1. Each unit system is capable of communicating with other systems via the communication network 2-6.

Figure 4 shows the central processing unit (
A control program (hereinafter referred to as "control program") for generating a program on the main memory that performs each layer function of the 7-layer logical structure of the O3I that exists on the main memory in the CPU) 2-2. FIG. In the figure, 4-1 is an application program control program for generating an application program, 4-2 is a presentation program control program for generating a presentation program, and similarly, 4-3 to 4-7 are , respectively, show a session layer control program, an h-transport layer control program, a network layer control program, a data link layer control program, and a physical layer control program.

FIG. 5 shows an overview of the operation in the system of this embodiment, and what it means is that the application control program 4-1, which is waiting for input, immediately responds to the data when it is input. An application program is generated to process the input data. The generated application program executes data processing, and when the processing is completed, outputs the processing result to the next layer, the presentation layer, and at the same time erases itself. When data is input, the presentation control program 4-2, which is waiting for input, immediately generates a presentation program for the data and processes the input data.

The generated presentation program executes data processing, and when the processing is completed, outputs the processing result to the session layer, which is the next layer, and at the same time erases itself. The same applies below. Here, when the input of processed data from multiple other programs occurs almost simultaneously, the control program of each layer is generated by the same program as the above-mentioned each data processing program for the number of input processed data. Then, the input data to be processed is processed in parallel by the generated data processing program, the processed data that is the result is output, and simultaneously with the output, it is erased.

The details of the operation of the control program will be explained below. Note that the control program operates the same in each of the seven layers, so the following explanation will be given.

The explanation will be given by taking the fifth layer, the session layer, as an example.

FIG. 1 shows the above-mentioned session layer control program,
That is, this is a schematic operational flow of a control program of a session layer program for realizing a session layer function. In the figure, when data to be processed is input to the session layer control program from a layer higher than the session layer or a layer lower than the session layer (step 11), the control program controls the central processing unit (cp
A session layer program is generated on the main memory by executing an instruction for generating a session layer program depending on the environment (O8) implemented by u) (step 12). Note that this generation may actually be obtained from the aforementioned external storage device or the like. next,
The control program outputs the processed data to the generated session layer program (step 13).
, the system waits for data input again.

FIG. 6 is a schematic flowchart of the session program.

The session program inputs the processed data output from the session layer control program in step 13 (step 51), and determines whether the data is output from an upper layer or a lower layer. (step 52). In the case of processed data output from an upper layer, after performing various arithmetic processing on the processed data, information data unique to the session layer (hereinafter referred to as "session information data") is added to the data. (step 53), and outputs it as processed data to the lower layer (step 54).

If the processed data is output from a lower layer, step 55) extracts the session information data necessary for the session layer from the processed data, performs arithmetic processing based on that information, and outputs the result. , and output as processed data to the upper layer (step 56). After outputting the processed data to the upper layer or lower layer, the session program executes a process termination instruction depending on the O8 (step 57), thereby
Erases itself from main memory.

The right side of the above flowchart shows the operation of adding session information data to the processed data output from the lower layer, and the left side shows the operation of extracting session information data from the processed data output from the upper layer. Ta.

In this embodiment, due to the above-described operation, even when data to be processed is input to a certain layer from multiple layers at the same time, the control program immediately executes the program by the number of data inputs. Since arithmetic processing is performed on the generated and input data to be processed, there is an effect that the time required to complete the arithmetic processing on the input data to be processed is significantly shortened.

In the description of the above embodiment, the session layer of the fifth layer was taken as an example, but the operations in other layers are similar.

〔Effect of the invention〕

As described above, according to the present invention, a central processing unit having an environment in which a plurality of programs can operate simultaneously, an external storage device capable of storing a large amount of programs, and an input/output means can perform simultaneous parallel operations. When transferring data between multiple programs, input of data to be processed from multiple other programs occurs almost simultaneously to one data processing program among the multiple programs running simultaneously in parallel. , generate the same program as the data processing program for the number of input data to be processed, cause the generated data processing program to perform arithmetic processing on the input data to be processed, and generate the processed data as a result. After outputting, the generated data processing program is deleted, so a data processing method that can shorten redundant time and improve the processing speed of the entire system without increasing the development load on program developers has been developed. This has the remarkable effect of being achievable.
