Description

[Detailed Description of the Invention] (A) Technical Field of the Invention The present invention provides a dynamically coupled module execution processing method,
In particular, the present invention relates to a dynamically coupled module execution processing method in which a common block is stored as one member on an external large storage device so that common data can be exchanged under modules that are dynamically coupled to each other.

(B) Technical background and problems There are multiple source modules each associated with a common block, and when at least one of these modules is executed, another module is called to execute the entire process. If there is a possibility that the load module may be loaded, there is a known method in which a plurality of modules are compiled as one load module member, ie, a static method, as will be described later with reference to FIG. However, in this method, the information is loaded onto the memory as one load module member. For this,
Modules that are not actually called are also loaded onto the memory, resulting in an undesired and unnecessary occupation of the memory area.

To improve the above point, as described later with reference to Figure 2, multiple source modules are compiled individually as load module members, and only the members needed during actual processing are compiled. A dynamic link method is known, in which a dynamic link method is used to load data into memory. However, in this case, each member individually has a common block, and it is not possible for each member to mutually refer to the common block.

(C) Object and Structure of the Invention The present invention aims to solve the above-mentioned problems. It prepares a common block as one member, and creates a common block while each module executes processing by dynamic combination. The purpose is to enable the exchange of data. For this reason, the dynamically coupled module execution processing method of the present invention has a plurality of source modules associated with common blocks, and one module can call another module during processing execution. A plurality of modules that have the possibility of executing the entire process are stored as load module members on an external large storage device, and the central processing unit carries out the load necessary for processing from the external large storage device. In a data processing system that processes module members by loading them onto memory, each of the load module members described above is individually stored on the external large storage device, and a common memory corresponding to each of the source modules described above is stored separately. The largest block among the blocks is stored as one common block member, and when executing processing, the central processing unit stores the individual load module members necessary for the current processing and the common block member. - Members are individually loaded onto the memory from an external large storage device, and processing is executed. This will be explained below with reference to the drawings.

(D) Embodiments of the Invention Fig. 1 shows the processing mode when the conventional static method is adopted, Fig. 2 shows the processing mode when the conventional dynamic link method is adopted, and Fig. 3 shows the processing mode when the conventional dynamic link method is adopted. 1 shows a mode of processing according to an embodiment of the present invention.

In FIG. 1, 1, 2, and 3 are source modules, 4, 5, and 6 are corresponding common blocks associated with the source modules, 7 is an external large storage device, and 8 is a central processing unit, etc. Virtual memory represents a processing unit, 9 represents loaded module members compiled as a unit, and 10 represents members loaded onto virtual memory.

In the case shown, the modules corresponding to the program subroutines are module X, module Y,
It exists like Module Z, for example Module
This is a case in which module Y or module Z may be called at the stage where processing corresponding to the above is executed. Note that the corresponding common blocks 4, 5, and 6 correspond to the corresponding modules 1 and 6, respectively.
2 and 3 are shown as corresponding ones.

When the source modules 1, 2, and 3 are given as described above, in the conventional static method, the modules X, Z, and Z and the corresponding common blocks 4 to 6 are The largest one (C(Y) in the illustrated case) is regarded as a single unit and compiled. The member 9 compiled in this way is stored on the external large storage device 7, and when the central processing unit executes the corresponding process, the entire member 9, such as member 10, is stored on the memory 8. It will be loaded and processed. In this case, the members 9 of the modules X, Y, and Z are constructed so that, for example, a linkage editor may be used to exchange common data using a common block (C in the figure).

In the case of the static method, member 9
are prepared and processed, but in actual processing, a case may occur in which only module X and module Y are used and module Z is not used. However, in the case of this method, member 9 (or 10) is treated as one unit, so in the above case, the part corresponding to module Z occupies an extra area of memory 8. I don't like it.

FIG. 2 corresponds to the dynamic link method, which improves the above points and makes it possible to load only the modules necessary for processing onto the memory 8. Reference numerals 1 to 8 in the figure correspond to those in FIG.
Reference numerals 1, 12, and 13 are load module members, in which the source module and the corresponding common block are made into one member. Reference numerals 14 and 15 represent members loaded onto the memory 8, respectively.

In the case shown in Figure 2, the illustrated members 11, 1
2 and 13, each source module and corresponding common block are compiled and registered as independent members. Although the details are omitted, the central processing unit is connected to the dynamic coupling mechanism 23.
As a function of the supervisor, for example, the member 14 is loaded onto the memory 8 and the module
member 12 while executing the process corresponding to
The configuration is such that the process corresponding to the module Y can be executed by calling the module Y and loading it onto the memory 8 as a member 15.

For this purpose, member 1 is stored on external large storage device 7.
After registering members 1, 12, and 13 individually, each member can be freely loaded onto the memory 8 according to processing convenience. That is, as shown in FIG.
There is no need to prepare it as a group of members 9. Therefore, in a case where processing corresponding to module Z is not performed while processing corresponding to module X is actually being performed, member 13 is not loaded onto memory 8. but,
In this method, members 11, 12, and 13 are independent of each other; for example, module ) cannot exchange common data such as reading the contents of the file.

FIG. 3 shows an embodiment of the process according to the present invention. Reference numerals 1 to 8 in the figure correspond to FIGS. 1 and 2, and 16, 17, and 18 are load module members, respectively, and the source module 1,
2 and 3, 19 is a common block member and has a size corresponding to the corresponding common block 5 which is the largest size, 20,
21 and 22 are members loaded onto memory 8,
23 represents a dynamic coupling mechanism.

In the case shown in FIG. 3, the central processing unit, for example, loads the member 20 onto the memory 8 and loads the module Needless to say, the configuration is such that the members 17 and 19 can be called and loaded onto the memory 8 while the process corresponding to the above is being executed.

In the case shown in FIG. 3, members 16 and 1 are installed independently corresponding to each source module 1, 2, and
7,18 have been compiled. A common block member 19 having a size corresponding to the largest of the illustrated corresponding common blocks 4, 5, and 6 is prepared. Needless to say, the members 16, 17, and 18 are combined so that the common block member 19 is treated as a common area.

Therefore, in the case shown in FIG. 3, the central processing unit loads member 16 onto memory 8 as member 20 and then loads member 19 into memory 8 while performing processing corresponding to module X. It is possible to perform processing such as loading member 17 as member 22 and writing common data therein, loading member 17 onto memory 8 as member 21, and having module 21 read the common data on member 22. becomes. That is, when each module X, Y, and Z can exchange common data as in the case shown in FIG. 1, and when the processing corresponding to module Z is not performed as in the case shown in FIG. The member 18 only exists on the external large storage device 7 and can enjoy the advantage of effectively utilizing the area of the memory 8.

(E) Effects of the Invention As explained above, according to the present invention, it is possible to enjoy both the advantages of the conventional static system and the advantages of the conventional dynamic link system.
