Abstract

PURPOSE:To reduce the capacity of an area storing an initialization information record train by producing an initialization information record with reduction of the record length and at the same time synthesizing plural initialization information records into one record for output. CONSTITUTION:An initialization information record production means 3 decomposes an initialization image into an initialization value pattern and its repeating frequency as the initialization information and produces an intermediate initialization information record containing the initialization information. An initialization information record train synthesizing means 5 synthesizes plural intermediate initialization information records having continuously the same initialization patterns into a single initialization information record out of those intermediate initialization information records produced by the means 3. As a result, the capacity of an area storing an initialization information record train 6 is reduced.

Description

[Detailed Description of the Invention] [Industrial Application Field] When initializing data, the present invention refers to an initialization information record having initialization information for each data, and converts the initial value image into data. The present invention relates to a processing system that is executed by transcribing to an address, and particularly relates to an initialization information record generation method.

[Conventional technology]

Conventionally, in this type of initialization information record generation method, the initialization information record has the initial value image as initialization information as it is, and initialization is performed by simply transferring the initial value image to the data address. It was carried out by Furthermore, one initialization information record was always created for one piece of data.

For example, if there was a name table as shown in FIG. 6(al), an initialization information record string as shown in FIG. 6(b) would be generated.

[Problem to be solved by the invention]

In the conventional initialization information record generation method described above, when an initialization information record is generated, only the initial value image in the initialization information record requires the same size as the data, so the initialization information record string is stored. The disadvantage is that the amount of space increases and the memory usage efficiency is poor.

In view of the above-mentioned points, an object of the present invention is to provide an initialization information record generation method that generates an initialization information record with a shortened record length and combines a plurality of initialization information records. .

[Means to solve the problem]

The initialization information record generation method of the present invention inputs a name table with detailed data definition information defined by the user and creates an initialization record with data initialization information necessary for initializing data during program execution. In an initialization information record string generation method that generates an initialization information record string, an initialization information record is created that generates an intermediate initialization information record that is decomposed into an initial value image and its repetition count and held as initialization information. and a plurality of intermediate initialization information records successively having the same initial value pattern among the intermediate initialization information records generated by the initialization information record generation means to create one initialization information record. and a means for synthesizing an initialization information record string into an initialization information record.

[Effect]

In the initialization information record generation method of the present invention, the initialization information record generation means is the first! The initialization information record generation means generates an intermediate initialization information record in which the tll value image is decomposed into an initial value pattern and the number of repetitions thereof and is held as initialization information. Among the intermediate initialization information records, a plurality of consecutive intermediate initialization information records having the same initial value pattern are combined into one initialization information record.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an initialization information red generation section 2 to which an initialization information record generation method according to an embodiment of the present invention is applied. This initialization information record generation unit 2 inputs a name table 1 having detailed definition information of data defined by the user, and generates the first set of data required when initializing data during program execution. UI (which generates an initialization information record string 6 having a information, and includes an initialization information record generation means 3, an intermediate initialization information record string 4, and an initialization information record string combining means 5. It is configured.

Referring to FIG. 2, the process in the initialization information record generating means 3 is a step of determining the same character in all digits.

13-1, intermediate initialization information record output step 3-2 for characters and data digits, "a11 constant" format determination step 3-3, and intermediate initialization information record output step 3-4 for initial value image. , data digit number constant digit number integral multiple judgment step 35, constant and repetition number intermediate initialization information record output step 3-6, constant and repetition number intermediate initialization information record, and residual initial value pattern intermediate initialization It consists of an information record output step 3-7.

Referring to FIG.
The following processes include an intermediate initialization information record reading and saving step 5-1, an unread intermediate initialization information record presence/absence determination step 5-2, and an identical initial value pattern consecutive address initialization determination step 5-3. It consists of a repetition count value addition step 54, an initialization information record output and intermediate initialization information record saving step 5-5, and an initialization information record output step 5-6.

Next, the operation of the initialization information record generation method of this embodiment configured as described above will be explained.

When the detailed data definition information is read into the initialization information record generation unit 2 from the name table 1, the initialization information record generation means 3 decomposes the initial value image of the read data into information such as an initial value pattern and the number of repetitions. Then, initialization information is created, and an intermediate initialization information record string 4 containing the initialization information is output.

In detail, the initialization information record generation means 3 first determines whether the initial value image of the data consists of one character that is the same in all digits (steps 3 to 1), and if all digits are the same 1.
If there is one character, an intermediate initialization information record is generated and outputted with the initial value pattern as the character and the number of repetitions as the number of digits of the data (stenob 3-2). If the initial value image of the data is not composed of one character that is the same for all digits, the initialization information record generation means 3 determines that the initial value image of the data is "all constant" (all constants).
Step 3
~3), if it is not configured in the format of "Fall constant", the initial value pattern is the initial value image itself of the data, and an intermediate initialization information record with the number of repetitions as 1 is generated and output (Step 3) -4). If the initial value image of the data is configured in the format of "Fall constant", the initialization information record generation means 3 determines whether the number of digits of the data is divisible by the number of digits of the constant (step 3-5). ), if it is divisible, an intermediate initialization information record is generated and output in which the initial value pattern is the constant and the number of repetitions is the quotient of the number of digits of the data divided by the number of digits of the constant (step 3-6). If the number of digits of the data is not divisible by the number of digits of the constant, the initialization information record generation means 3 first sets the initial value pattern to the constant,
Generates and outputs an intermediate initialization information record in which the number of repetitions is the integer part of the number of digits in the data divided by the number of digits in the constant, and then when the number of digits in the data is divided by the number of digits in the constant. An intermediate initialization information record is generated and outputted using a character string with the remainder of digits as an initial value pattern and the number of repetitions as 1 (step 3-7).

Fig. 4 Fa) and (bl are diagrams showing an example of generation of intermediate initialization information record string 4. That is, Fig. 4 ta+
Definition of data in which the initial value image of data is composed of the same single character for all digits in name table 1 as shown in Figure 1. Definition of data whose detailed information and initial value image of data are composed of "all constant" format. If there is detailed information, the initialization information record generating means 3 generates the information as shown in FIG.
An intermediate initialization information record string 4 consisting of three intermediate initialization information records with a shorter record length than storing the initial value image itself as shown in bl is output. It should be noted that each intermediate initialization information record includes, in addition to the initial value pattern and the number of repetitions, a pointer consisting of an address indicating the transfer destination of the initial value.

Next, the initialization information record string combining means 5 receives the intermediate initialization information record string 4 generated by the initial information record generation means 3, and successively combines a plurality of initialization information records having the same initial value pattern. The information records are combined into one and output as an initialization information record string 6.

Specifically, the initialization information record string combining means 5 first reads one intermediate initialization information record from the intermediate initialization information record string 4 and saves it to a saver sofa (not shown). Then, the next intermediate initialization information record is read and it is determined whether there is any intermediate initialization information record yet (steps 5 to 2). If there are still intermediate initialization information records, the initialization information record string matching means 5 compares the intermediate initialization information records just read with the intermediate initialization information records on the save buffer and determines the initial value pattern. If the initial value pattern is the same and the addresses to be initialized are consecutive, check whether the addresses to be initialized are the same and are consecutive based on the pointer.If the initial value pattern is the same and the addresses to be initialized are consecutive, the Step 52: Add the number of repetitions on the intermediate initialization information record that has just been read to the number of repetitions on the intermediate initialization information record to effectively update the initialization information record 5-4), and read the next intermediate initialization information record. Returns control to processing. first time! If the tll value patterns are different or the addresses to be initialized are not consecutive, the initialization information record string alignment means 5 outputs the intermediate initialization information record on the evacuation sofa as an initialization information record and then reads it. The intermediate initialization information record is saved on the save Hanofa (steps 5 to 5), and control is returned to the process of the step knob 5-2 which reads the next intermediate initialization information record.

In step 5-2, intermediate initialization information record string 4
If there is no intermediate initialization information record that is no longer read in, the initialization information record string synthesis means 5 outputs the intermediate initialization information record on the evacuation sofa as an initialization information record (step 5-6); Finish processing.

FIG. 5 +al to [Q+ is a diagram showing an example in which the initialization information record string 6 is synthesized. That is, when there are two pieces of definition detail information of data consisting of one character with all digits in the name table 1 as shown in FIG. 5(a), the initialization information record generating means 3 An intermediate initialization information record string 4 consisting of two intermediate initialization information records with a shorter record length than storing the initial value image itself as shown in Figure 5 (bl) is generated, and these intermediate initialization information records are The initialization information record strings are synthesized by the initialization information record string synthesis means 5, and one initialization information record as shown in FIG. 5 (C1) is output.

〔Effect of the invention〕

As explained above, the present invention generates an initialization information record by shortening its record length, and also enables a plurality of initialization information records to be combined and output as one initialization information record. This has the effect that the amount of space for storing the conversion information record string can be reduced as a whole.
