BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing device,
In particular, the present invention relates to an information processing device for comprehensively managing and managing information, work processes, etc. in factories and offices.

[0002]

2. Description of the Related Art In constructing a device for highly automating information and work processes in factories and offices such as FAs and OAs, and for comprehensive management and operation, in computer terminals, work robots, etc. There is a demand from the user side for a so-called multi-vendor environment in which an FA or OA system can be freely assembled without being bound by the manufacturer or the OS on the computer.

As a problem in setting up this multi-vendor environment, there is a problem that programs and data cannot be mutually used between different models. This is because, for example, in a certain factory A, work and processes are managed using a computer,
Create an automated system,
When this is transferred to another factory B or the like, there is no problem if the computers used there are of the same model, but if the computers are different, the work performed as that factory B is the same, You have to create a program for the computer used in Factory B. This is usually
This is done by porting what was created in the previous Factory A, which requires virtually the same effort and cost as writing a completely different program. In addition, adding a certain work or process requires a new program that incorporates the part of the work process you want to add, which means that even if the main routine is the original program, it is a slight addition change. Even if you create a new program that is different from the original program, it will be no different from the original program, and it will require a lot of effort, and the newly created program will be used for the whole debugging and test run. Is necessary, and more labor, time, and cost are required, which is a big problem.

In order to solve such a problem in setting up such a multi-vendor environment, the applicant of the present invention adds a function for complementing each OS to each OS so that different models or OSs can be used. Even if there is that model and OS
We have developed a platform that allows program porting and program execution without being aware of the above.

FIG. 6 is a drawing conceptually showing this platform.

This platform includes a storage means for storing one or a plurality of application kits 1 and 2 defined only by an execution element procedure without including a determination process and a process of storing and retaining information, and the kits 1 and 2
Means SKI3 consisting of a group of libraries for building and running the kit independent of hardware and OS, and storing and processing the flow of the built kit, and temporary storage and processing of information shared between applications. Means BASE4 for managing and executing and OS attached to the BASE
A device driver (D / D) 41 for accessing a device that cannot be directly accessed by the user, a graphic user interface (GUI) 42 for displaying a chart on the screen, and the kits 1 and 2 and BASE 4
Means for supplying a function group for completely separating and operating the OS from the hardware or OS7, and a storage means for storing a work procedure that functions only on a specific OS, function on the SKI3 and BASE4 without remaking. ,
An information processing device comprising: a means API6 for matching with the kit 1 or 2.

However, when this platform is made to function on each OS, although the program can be ported and the program can be executed without being aware of the difference in the model and the OS, all the functions of this platform are used. In the case of such a processing device, a platform corresponding to many functions causes a problem that the execution speed is delayed when the program in the processing device is processed.

[0008]

Therefore, in the present invention, FA or O can be freely set regardless of the difference in hardware or OS.
An object of the present invention is to provide an optimization method of an information processing device that realizes an information processing device that is suitable for a so-called multi-vendor environment in which the system A can be assembled without reducing the processing speed of the program.

[0009]

The above-described object is to prepare a plurality of one-unit basic programs configured to perform a certain basic process, activate the basic programs in an arbitrary order, and perform a predetermined process. On the other hand, in an information processing device that causes a predetermined process to be performed by an existing program used in arbitrary hardware,
An address of a storage area in the information processing device is divided into a plurality of blocks, an address necessary for processing the basic program or an existing program executed by the information processing device is searched and specified, and the specified address This is achieved by the method for optimizing the information processing apparatus, characterized in that the block not containing is released as a user use area.

[0010]

The method of optimizing the information processing apparatus according to the present invention allows the FA to be freely selected regardless of the difference in hardware or OS.
Or OA system capable of forming a so-called multi-vendor environment, an information processing device equipped with a platform supporting many functions, that is, one unit configured to perform a certain basic process. While preparing a plurality of basic programs and activating these basic programs in an arbitrary order to perform predetermined processing,
In an information processing apparatus that causes an existing program used in arbitrary hardware to perform a predetermined process, the address of a storage area in which a platform is developed is divided into a plurality of blocks and executed on this information processing apparatus. Find addresses used by the program,
Efficient platform operation can be achieved by identifying and deleting the block containing the unused address for each block, and deleting the functions that are not required for program execution in the deleted block. Can be done. Therefore, a processing device adapted to a multi-vendor environment can be realized without reducing the processing speed of the program.

Next, the means OSI5 for supplying a function group for operating the kits 1 and 2 and the BASE4 part completely separated from the hardware and the OS7 is expressed in a simple manner. It plays a role of converting functions used in the OS 7 that differ depending on the model of hardware to be executed, processing functions on the OS 7 that depend on the hardware, and the like into functions that are used in this device. To this end, the instruction system of the OS 7 which is the basis of each hardware device (the same instruction actually causes a different instruction to actually operate the computer, but the number of arguments and the number of return are different due to different OSs) It has an OS library to refer to in order to convert it into the functions used above. That is, the OS library is a table for associating the instruction types of each OS 7 with the corresponding instruction types on the apparatus. Then, when the execution instruction input from each terminal is received, the OS library is referred to, the necessary instruction form on the device is converted, and the result executed on the device is converted to the hardware. By converting the data to match the display or execution form and sending it back, the processing work constructed by the software kit can be performed regardless of the model.

Further, the OSI 5 can be provided with a function function of complementing the function of the OS 7 depending on the hardware. This is because the functions of the OS 7 that are usually dependent on the hardware include functions and processing instructions that are characteristic of the hardware and the OS 7, and these functions may or may not exist depending on the hardware model. Therefore, it is becoming difficult for users to use due to the change of model, and in addition to eliminating such inconvenience, it will be more functional and easy to use by adding easier-to-use functions and instructions. You can

Next, the API 6 has a function of converting an execution instruction of an application program that can be executed only on a specific OS into an instruction on this apparatus by referring to the above OS library. Is.

With the functions of the API 6 and the OSI 5 described above, it becomes possible to execute the application program in a different model of the OS 7 without being aware of the OS 7 on the computer and the OS 7 of the application program.

The conversion by the OSI5 and API6 described above is not performed as in the conventional method such as generating a program in which a program consisting of an execution instruction of a certain OS7 is ported to an instruction type on this apparatus. Instead, an instruction from each terminal or an instruction when an application program is executed is specified in the execution instruction and is operated in the present apparatus. This also allows only some of the instructions in the application to be executed, and D together with Kits 1 and 2 above.
It becomes possible to combine and execute by FD.

Due to the functions of the various parts of the platform as described above, even if the information processing device is of a different model or OS, the program can be ported and the application software can be executed without being aware of the model or OS. .

In the method of optimizing the information processing apparatus according to the present invention, first, the address of the storage area in which the functions of the above-mentioned platform inside the information processing apparatus are expanded is appropriately divided into blocks. For example, as shown in FIG. 3A, the address areas 0 to FFF are divided into each block. Then, from the program executed by this processing device,
Find the address that the program is using and see Figure 3b
Create a used address table as shown in Fig. 3 and delete the blocks of addresses not used by the program in the address area divided into blocks as shown in Fig. 3c.
Only the address used by the program is relocated as an address area when the program is executed, and thereafter, as the address used in this information processing apparatus, the relocated address shown in FIG. Addresses not used by the program are released as a user area.

Next, an apparatus configuration for executing the optimization method of the information processing apparatus of the present invention will be described. FIG. 4 is a block diagram for explaining an embodiment of the optimizing device for executing the optimizing method of the information processing device of the present invention. The optimizing device 10 includes a branch condition search unit 11 that searches the source code of the program 101 for a branch condition of the program, an object code of the program 101, and a branch condition search unit 1.
1 executes virtually all branch conditions of the program 101 from the branch conditions searched by 1 and the object code of the platform 100, and creates a simulator 12 for searching and specifying an address used by the program 101 and a used address table. , Used address table storage unit 13 for storing used addresses, platform 10
An address dividing unit 14 that divides an address in which 0 is expanded into a plurality of blocks and creates a block table,
The block table storage unit 15 that stores the block table created by the address division unit 14, compares the used address table with the block table, deletes the block including the address not used by the program 101, and deletes the new block. It comprises a new block table creating unit 16 for creating a table and a new block table relocation unit 17 for relocating the new block table created by the new block table creating unit 16 as an address where the platform 100 is expanded.

Next, the implementation of the optimization method of this information processing apparatus will be described. FIG. 5 is a flow chart for explaining the optimization of the information processing device using the optimization device 10. First, kit 1 on the platform
The branch condition search unit 11 reads all the source codes of the program 101 or the program 101 made up of existing software, and searches and selects all the branch conditions in the program 101 (S1). Next, when the object code of the program 101 is read and virtually executed by the simulator 12 in accordance with all branch conditions (S2) and a jump is made to an address in the platform 100, a used address table is created from that address and the used address is used. It is stored in the table storage unit 13 (S3). After confirming that all the branch conditions have been executed by the simulator (S4) and all the branch conditions have been executed and the used address table of the accessed address has been created, the address where the platform is expanded is divided into addresses. The block 14 is divided into blocks by the unit 14, the block table stored in the block table storage unit 15 is compared with the used address table, and an address that has never been accessed is included in the blocks in the block table. The block is deleted, and a new block table is created by the new block table creating unit 16 (S5). The created new block table is relocated by the new block table relocation unit 17 (S6) and used as the address of the platform 100.

To give an example of optimization, for example, when the program 101 does not require keyboard input from the user or screen display on the terminal, the address where the GUI 42 is expanded is not used. , The block of that part is deleted as described above. Similarly, if the program does not use the OS call, the OS call conversion function in API 6 and the file access function in SKI 3 if the file is not input / output are the devices, software and users on the platform. When allowing access to all, the security functions in BASE4 are deleted respectively.

In this way, by releasing addresses not used by the program from the storage area, functions not used when executing the program are deleted, and a processing device optimized only for the functions used. As a result, the processing can be executed efficiently. Also, the address of the deleted block can be used as a user area.
