Abstract

PURPOSE:To neglet processing time compared with keying time in terms of alphanumeric by changing the flow of data with Japanese word processing start/end instruction and minimizing overheads of an OS down to several steps against the alphanumerics. CONSTITUTION:When a Japanese word processing start key is pushed, an interruption 105 is applied to a KANA (Japanese syllabary)/KANJI (Chinese characters) conversion program 106 via an interruption process 104 of a kernel 103. The program 106 produces a system call 107 to the kernel 103 and switches the input routes. The increase of overheads can be reduced down to just several steps against the alphameric and therefore ignored against the keying time. The data inputted to the program 106 are converted into KANJI and delivered to a suer program 101 and at the same time displayed on a CRT 108. When the KANJI input processing is through and then a Japanese work processing end key is pushed, the call 107 is produced via the process 104, etc., and the flow of data is switched to an alphanumeric input process 109.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a Japanese language processing method for an electronic computer, and particularly to a Japanese language processing method suitable for a system in which a kana-kanji conversion operation is incorporated into an OS.

[Conventional technology]

Japanese language processing is handled by O, represented by the Japanese word processor.
We are currently expanding our focus on A-only machines.

Japanese language processing is also being incorporated into general-purpose computer systems or workstations for the purpose of making them multipurpose and multifunctional. Kana-kanji conversion processing occupies the center of this Japanese processing, and the method of incorporating this kana-kanji conversion processing mechanism requires an "OS built-in type" built into the OS, and Japanese input processing. There are two types: ``external type'' in which the program itself has a kana-kanji conversion processing mechanism, and ``terminal device type'' in which the terminal device itself has a kana-kanji conversion mechanism. (Nikkei Electronics 1984. UNIXJ is expanding its functions such as Japanese real-time network.
10.22, p188).

Among these, the "OS built-in type" is superior in that it can uniformly send Japanese to various programs in the computer system without changing them, and also provides advanced input functions. Regarding this "OS built-in type" Japanese input processing method, see pages 190 to 192 of the above-mentioned document, "Japanese processing on rUX-300", Information Processing Society of Japan 2nd Edition.

As described in the Nikkei Byte November 1984 issue, p. 57.60, a program (equivalent to a task) dedicated to kana-kanji conversion processing called a ``kanji daemon'' is provided inside the OS.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology has problems with the following two points. 1st
Even when inputting alphanumeric characters, all the input data passes through the above-mentioned kana-kanji conversion program, so there was a problem that the input processing overhead increased.1 In normal terminal operation, various application programs are often created, and in Japan Since there is more alphanumeric input processing than word input processing, the fact that alphanumeric input processing takes longer due to increased overhead has a significant impact on program productivity. The second problem is that normally, many people use many terminals to simultaneously develop programs and execute application programs on computers, and if all input data is input via the kana-kanji conversion program, Depending on the operation status of many other tasks, the ready-made OS
A delay occurs in the communication processing of conversion data between the program and the kana-kanji conversion program, which further increases the delay in input time and deteriorates responsiveness.

An object of the present invention is to provide a Japanese electronic computer that can input characters other than kanji at high speed without increasing the overhead for inputting characters other than kanji, and without being affected by other tasks even when used by many people at the same time. The object of the present invention is to provide a word processing method.

[Means for solving problems]

The purpose of the above is that when an instruction to start Japanese processing is input from the keyboard, the subsequent input data is imported into the Kana-Kanji conversion program and processed; otherwise, the input data is converted into conventional alphabets and numbers. This is achieved by providing a switching function within the OS for directly inputting information to the processing program.

[Effect]

The kana-kanji conversion program has a structure that can operate independently as a task (process) separate from the OS, and can communicate data control information with the OS. Therefore, when the kana-kanji conversion program receives an instruction to start processing Japanese through an interrupt.

Switches the input so that all input data from the keyboard is taken into its own processing, and treats subsequent data as the source data for converting into kanji.0 When the instruction to end Japanese processing is sent by interrupt as above, the input switch,
By controlling the flow of data so that it is not imported into its own processing, and by changing the data flow using Japanese processing start/end instructions, the OS overhead for alphanumeric characters often used in programming can be reduced. It is minimized to a few steps for making decisions, and can be ignored when compared to the time it takes for an operator to type on a keyboard. Furthermore, even when Japanese language processing starts and input kana is converted into kanji, the overhead of the OS is several steps, so there is no deterioration in responsiveness due to the provision of the Japanese language processing function.

〔Example〕

The present invention will be explained below with reference to the drawings. FIG. 2 is a diagram showing the configuration of a computer system to which the present invention is applied, and a computer main body 201 consists of a processing device and various types of memory. This internal program processes input of Japanese data used for alphanumeric characters, kanji, etc. from the keyboard 102, and displays the data on the CRT 10g.

Figure 1 shows the operating system of a computer for realizing the method of the present invention.
This shows the functional configuration of the relevant parts of the kernel in S.
An outline of the method of the present invention will be described with reference to this figure. First, operation keys such as Japanese language processing start and end keys are registered in advance in a table used on the OS side. When one of these Japanese processing start keys is input, an interrupt is generated in the kernel 103, and in the interrupt processing 104, it is determined whether the input data is the Japanese processing start key. From process 104, an interrupt 105 is again made to the kana-kanji conversion program 106, and control is transferred to the program 106.The kana-kanji conversion program 106 issues a system call 107 to the kernel in order to handle data input from the keyboard 102 from then on. A system call is a call that switches the input path so as to import input data into its own program.A system call is a call that controls the execution of a program, executes a complex procedure to control hardware, or a call that may cause a failure to the entire system. Kernel 10 for executing certain processing
This is a standard procedure for requesting processing from 3rd party.

The manual switching process is built into the interrupt process 104 of the kernel 103, but this was added to determine whether the Japanese processing start key has already been pressed. The impact on numerical data is only a few steps; in other words, the increase in overhead for alphanumeric data due to the addition of Japanese processing is
Considering the operator's keystroke time, this can be ignored.

The data that has entered the kana-kanji conversion program 106 is
CR
The converted kanji are also displayed at T 108 along with the input characters. For this display, for example, CRT108
The lower two lines of the screen are occupied by a kana-kanji conversion program 106, the upper one line of the two lines is used as an input character, and the lower one line is used for guidance display and for converting input data into kanji or the like. In this case, the area available to the user is the screen area excluding the bottom two lines. Also.

By pressing the key to end Japanese processing, the bottom two lines of the screen that were occupied will be released.

When the kanji input process is completed and the Japanese processing end key is pressed on the keyboard 102 to input alphanumeric characters again,
System call 10'7 is issued via interrupt processing 1042, interrupt 105, and kana-kanji conversion program 106, and the flow of data is switched to alphanumeric input processing 109. The alphanumeric data thus input is passed to the user program 101 and also displayed on the CRT (108).

In general, kana-kanji conversion programs are 60 to 15
0 bytes (processing steps) is required, and if this large processing is incorporated into the kernel 103, the memory in which the user program 10 operates will be significantly reduced, increasing the total system load. If the program 106 is provided as a separate task from the kernel as shown in FIG. 1, Japanese language processing can be realized with almost no increase in the capacity of the kernel 103.

An example of a program for realizing the processing of the present invention as described above will be described next. Figure 3 shows the flow of the part of the kana performance one-character conversion program that is related to the present invention. Executes the process of setting the type of connected terminal, etc.

That is, the started kana-kanji conversion program 106 first takes in environment information and terminal information necessary for Japanese language processing from an external table and makes initial settings in step 301. Here, the environment information and terminal information include information such as the file name of the system dictionary and the default execution mode.1 Information about the terminal's cursor control information and the assignment of operation keys required for Japanese input. ESC required
(escape) sequence information, etc.1 For example,
If you assign a key to indicate the start and end of Japanese processing to "K" (press the control key and K at the same time), the Kana-Kanji conversion program 106 will import information from an external table and The code is sent to the kernel 103.The kernel 103 stores the code sent from the kana-kanji conversion program 106 in an internal table, and starts Japanese processing by determining whether the input data is "AK". - It is possible to distinguish whether a termination instruction has been given or not. On the other hand, Kana-Kanji conversion program 10
6, the code "r'K" fetched from the table is stored in an internal table, and an interrupt 105 (Fig. 1) indicating that a key has been pressed to instruct the start/end of Japanese language processing is issued from the kernel 103. If the code is entered, it can be determined whether the Japanese language processing has started or ended by determining how many times the "K" code has been entered.

Next, in step 302, terminal attributes are set for the terminal device, a file opening process for a terminology dictionary used in the kana-kanji conversion process is performed, and interrupt information is registered in step 303. inside the computer.

Since a large number of interrupts are used, it is necessary to give each one a meaning, and this step 303 gives a meaning indicating "start/end of Japanese processing" used between the kernel and the kana-kanji conversion program. When one or more initial processes are completed, the kana-kanji conversion program 106
The Japanese language processing start key will wait for human power (step 30).
4).

When the kana-kanji conversion program 106 is waiting for the Japanese language processing start key manual input MA (step 304), when the Japanese language processing start key is input from the keyboard, an interrupt is generated from the kernel, and this is input from the interrupt entrance 311. When this interrupt occurs, the Japanese language processing start key is first determined (step 309).
A counter with an initial value of 0 is prepared in advance in the initial setting step 301, and if O, the counter is set to 1, and the process proceeds to the next Japanese input start processing step 305 of the kana-kanji conversion program, where the reading of the kanji is input. step 306,
Step 308 of the kana-kanji conversion process is executed and the process returns to step 304 again. However, if the above counter is other than O,
The counter is initialized (cleared to zero), the Japanese language termination process is performed in step 310, and the kanji process waits for key human power to start the next Japanese language process.

FIG. 4 shows the flow of input switching processing on the kernel side, and corresponds to the interrupt processing 104 in FIG. 1. In this process, when there is an input from the keyboard, it is determined whether the input data is a Japanese start key (step 401).
) L,, If it is the Japanese start key, an interrupt registered by the kana-kanji conversion program is generated and the process proceeds to the interrupt entrance 311 in FIG. 3 (step 404).
If the key is other than the 0 Japanese processing start key that executes the processes from step 309 onward in the figure, a process to determine whether Japanese processing is currently in progress is performed (step 402), and if not, input data is requested. The system call 107 in FIG. 1 passes the data to the user program 101 that is currently processing the data, passes the data to the kana-kanji conversion program 106 if Japanese processing is in progress, and performs the operation of converting the data into kanji on the kana-kanji conversion program side. This judgment process (step 402
), it provides information on which side to send data to.

〔Effect of the invention〕

According to the present invention, the kernel only judges whether Japanese processing starts and ends and whether Japanese processing is in progress, and the increase in kernel overhead when inputting alphanumeric characters is caused by the operator. Since it takes only milliseconds compared to the time required to type a key (on the order of seconds), it hardly reduces the efficiency of system operation. In addition, if the terminal uses English characters, there is no need to perform Japanese processing, and the OS
Since the kernel part of the OS can be used as is, there is no need for double management in terms of software maintenance, and the costs required for providing, maintaining, and managing the OS can be significantly reduced. Furthermore, since the kana-kanji conversion part, which is the key to Japanese language support, is created separately from the OS kernel, it has the feature of being able to easily follow future technological innovations in Japanese language support. There is an advantage in that it can be applied to foreign languages other than Japanese (for example, Chinese) by creating a program corresponding to the kana-kanji conversion part according to the grammar of the foreign language and preparing a dictionary.
