Abstract

PURPOSE:To improve modularity by executing common processing by a master module only when individual processing is not executed by a slave module, and adding exceptional processing to the slave module as necessary. CONSTITUTION:When it is supposed that a processing result of command failure is obtained from individual apparatus control processing 2a-c at the time of transmitting an individual apparatus control command from the outside of the system, input information and the processed result 4b are transmitted to a common input processing submodule 1b as a processed result 4C. Common processing is executed by a common output processing module 1a and individual processing is executed by an individual output processing submodule 2a. Since the common processing is executed by the master module only when the individual processing is not executed by the slave module, system operation can be attained by adding exceptional processing only to the slave module. Thereby modularity can be improved.

[Problem to be solved by the invention]

In the conventional information processing method described above, when several lower modules that perform individual processing depending on the processing purpose are prepared and used interchangeably, a specific lower module may be If you change the process so that exception handling is performed only for the upper and lower modules, and common processing is performed for other lower-level modules, even though the module structure is adopted, the processing in the upper and lower modules will be changed for all modules. There was a problem that I had to do without it.

Furthermore, if the lower module is not changed and exception handling is performed when the upper module performs common processing, there is also the problem that the upper module's processing depends on the lower module.

This invention was made to solve the above-mentioned problems, and even if the above-mentioned changes are made on the processing system, all you have to do is add that processing to the lower-level module where you want to handle exceptions. The purpose of this study is to obtain an information processing method that can provide high moshularity.

[Means for Solving the Problems] The information processing method according to the present invention has changed the method in which common processing is performed and then individual processing is performed in lower modules, and the upper module performs processing on the lower modules as soon as it does anything. According to the result of the processing of the lower module, processing of the upper module is performed as necessary.

[Effect]

In this invention, the common processing by the upper module is executed only when no individual processing is performed in the lower module, so the upper module does not need to have information about the lower modules, and only the common processing Lower modules that do not require exception handling need not be changed, and the processing can be added only to lower modules that require exception handling, thereby increasing modularity.

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

FIG. 1 shows the configuration of the main parts of a module diagram of a terminal processing system in a computer system that employs the information processing method according to the present invention. In the figure, the same or equivalent parts as in FIG. is used.

The only difference is the configuration of the common input processing sub-module (lb) constituting the common processing module, and the detailed processing procedure is shown in FIG. The equipment control command ×P (1≦p≦il) in Fig. 2 is normally processed by the common processing module (1), but only for a specific individual processing module is an exceptional individual processing This is a command that requires .

FIG. 3 shows the processing procedure of the individual device control processing (2a-c) in this specific individual processing module (corresponding to (2a)), and in this embodiment, this individual processing module is connected.

Next, the operation of this embodiment will be explained.

Now, suppose that an individual device control command x1 is sent from another component of the computer system as an output request and a device control command (3a). This individual device control command x1 is received and processed by the common output processing submodule (la). la-a) and common equipment control processing (la-c)
is executed, but since this individual device control command x1 is an individual command, it is sent as is to the individual output processing submodule (2a). This individual device control command X1 is sent to the individual output processing submodule (2a).
reception processing (2a-a), and individual device control processing (2a-a).
-c) is executed.

Then, the individual device control command x1 is processed according to the procedure shown in FIG. 3, and the processing result (4c) is sent to the individual manual processing submodule (2b). This processing result (
4c) is transmitted to the common human processing sub-module (lb) as human power information and processing result (4b) by the receiving process (2b-b) of the individual human processing sub-module (2b).

Next, the human power information and processing results (4b) sent to the common human power processing submodule (lb) are processed by the receiving process (lb-b).
) will be applied. The processing result is the individual device control command
, indicates that it has been processed, so it is simply transmitted as the human power information and processing result (3b), and no common processing is performed.

On the other hand, if two individual device control commands are sent from other components of the computer system instead of one individual device control command, the command failure will occur in the individual device control processing (2a-c) shown in FIG. The processing result is the processing result (4C), and the common human power processing submodule (1b) is the human power information and the processing result (4b).
) will be sent to. However, according to the flowchart of FIG. 3, a common process (lb-a) similar to that for the individual device control command X3 is executed.

Thus, the common processing is carried out by the common output processing submodule (
1a), and individual processing is performed in the individual output IA processing submodule (2a). In this case, the common output processing submodule (la) is the common human processing submodule (1
b) can be any module; if a module exceptionally performs individual processing, only the individual processing procedure is added to the individual device control processing (2a-c); no other changes are required. I don't.

Note that in the above embodiment, common processing is executed only when individual processing is not performed, but after execution of individual processing, common processing is performed only for the parts that were not processed, and the lower module It is also possible to store incomplete processing in a higher-level module.

Furthermore, in the above embodiment, the present invention is applied to terminal input/output processing, but it can be applied to most processing systems in which a plurality of modules that communicate with upper or lower levels are connected in cascade. Smells similar effect.

(Effects of the Invention) As explained above, according to the present invention, the processing in the upper module is postponed after the processing in the lower module, so modularity can be achieved with technical ease and without increasing costs. The effect is that it can be improved.
