Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is used for creating software. The present invention relates to a method for generating patch images in program creation.

〔overview〕

The present invention is a patch image generation method for software creation, in which a patch image is created by writing an updated image to memory and outputting it to a temporary work area, and obtaining an image of the location in real memory to be updated from an address. By obtaining information about the modules to be changed, checking the updated contents, and creating patches and images, it is possible to reduce the number of man-hours required to create programs and improve work efficiency.

[Conventional technology]

In program creation, a program created by source coding is modified on the source image in the first half of the manufacturing process to create a program having functions according to the design. In contrast, in the latter half of the manufacturing process, patches are created by constructing patches on the object image of the program.

Conventionally, this patch creation work involved the person in charge of producing the program referring to the object program list of each program, creating a patch image that describes the appropriate solution to the problem using instruction code, and applying this to the object of each program. Construction and execution were proceeding with full+J.

Also, during confirmation work using a machine, a memory patch is applied to the program currently being executed and loaded into memory, and after confirming the execution, a separate image of how to deal with the applied patch is created. , we are working on applying this patch to system programs that require similar measures.

[Problem that the invention seeks to solve]

As described above, the conventional patch creation work is extremely inefficient and is a major factor in deteriorating work efficiency in the manufacturing process.

Furthermore, since patch construction is carried out in the latter half of the manufacturing process, high quality patches are required. However, although manufacturing personnel are familiar with source program description languages, they are usually unfamiliar with techniques for describing patch images. At the time of checking the machine, the problem was dealt with directly in memory, so the idea of how to deal with it was clear, but there is a risk of taking the wrong measure when recoding it as a patch image. Therefore, the quality and performance of the patches that are created may result in unfavorable results and may continue to cause further problems.

These problems not only significantly reduce software productivity, but also carry the risk of further aggravating the problem.

The present invention solves these problems, and aims to provide a method that can reduce the number of steps required to recreate patch images and improve quality and productivity.

[Means for solving problems]

The present invention includes a console terminal and a display means, a real memory reference hand that reads information in a real memory area into a buffer area, and an operation instruction analysis means that analyzes instructions input from the console terminal and issues an update instruction. and,
In the patch image generation method, the patch image generation method includes a real memory updating means for updating the real memory area according to instructions from the operation instruction analysis means, the patch image generation method is controlled by the real memory updating means, and the real memory area is updated by the real memory updating means. An update image pushout means that directly writes the update image to real memory and outputs it to a temporary work area, and a change target that obtains the image of the real memory location to be updated from the change location address and creates a punch image. An update point reference means to obtain information about the module, an update point check means to use the section information management database to check whether the updated content violates the patch construction regulations, and a means for saving and opening to other systems. and patch image generation means for creating a patch image and automatically outputting it to a patch image file.

[Effect]

The update image pushout means writes an update image that updates the real memory area created by the memory change image creation means directly to the memory, and outputs it to a temporary work area in parallel, and the update location reference means updates it. An image of the real memory location is obtained from the modified location address, and information about the module to be modified is obtained from the section information database that manages information for each module in order to create a patch image. After checking whether there is a violation of the patch construction regulations, the patch image generation means creates a patch image for storage and release to other systems, and outputs it as a patch image file.

This allows patch images to be automatically generated, reducing man-hours and improving quality and productivity.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an automatic patch image generation method according to the present invention.

The embodiment of the present invention is positioned as a sub-function of the real memory update means 1 that updates the contents in the real memory area 7.

Normal updating in the real memory area 7 is performed in the following procedure as shown in FIG. The information in the real memory area 7 is read into the buffer area 3 by the real memory reference means 2. The information in the real memory read into the buffer area 3 is referenced from the external console terminal 4 using the display means 5 as is normally done.

After that, a memory patch is applied to the image on the real memory from the console terminal 4. In this memory patch work, the operation instruction analysis means 6 analyzes instructions input from the console terminal 4 and instructs the real memory update means 1 to update the real memory area 7.

The present invention provides a real memory area 7 in this real memory updating means 1.
An update image pushout means 8 outputs an update image to a temporary work area in parallel with directly writing an update image to the real memory, and a section information management database 9 is read from the update target location address in the real memory area 7. Updated location reference means 1 that is used to check updated locations
0, the update/image output by the update image pushout means 8, and the results checked by the update location reference means 1O to generate a patch image to be saved, and output it to an external patch image file 11. and check whether the updated content violates the patch construction regulations using the Sekunyong Information Management Database 9.
Equipped with.

Next, the operation of the present invention will be explained with reference to the drawings. First, the process up to the creation of the actual update image has already been realized using conventional technology, as shown in FIG. FIG. 2 particularly shows the patch image creation method which is the key point of the present invention.

The memory patch constructed from the console terminal 4 is analyzed by the operation instruction analysis means 6 and then passed to the real memory update means 1. Upon receiving this, the update processing control means 13, which is a sub-function of the real memory update means 1, instructs the real address search means 14 to search for the real address 21 in the real memory area 7 corresponding to the updated location (step 127).
It also requests the memory change image creation means 16 to create a memory change image 24 corresponding to the updated content. The memory change image creation means 16 updates the content 21 of the update target location using the memory image update means 15 (step 129). Changes to real memory at the same time 2
3 is output to the update image file 22 by the update image pushout means 17 (step 128).

On the other hand, in order to obtain section information regarding the updated location, the updated location reference means 18 obtains the update target image in the real memory area 7 from the updated address (step 130). Next, the section information management database 9 is searched to obtain section information regarding the updated location and output to the updated location check file 25 (step 131).

The image of the update target location output to the update location check file 25 is compared with the update location image 24 and the update image 23 output to the update image file 22 to perform a before and after update check regarding the update location and update content.
Step 132).

As a result of the before and after update check (step 132), the patch image creation means 20 generates a patch image to be saved from the before and after images that are determined to be valid updates (step 133).
