Abstract

PURPOSE:To decrease the frequency of input/output operation and to reduce the load on a host computer by transferring plural external characters, selected among data sent from an input/output device at the same time, as one block corresponding to each terminal device to the host computer through a cluster device. CONSTITUTION:When a graphic character that a display device 3 and a printing device 4 do not have is generated, the external character processing mechanism 5 of the cluster device 2 is actuated for primary external character processing to search for a graphic character pattern that the cluster device has. When data to be displayed or printed include plural graphic character data (secondary external character) which are not found among corresponding graphic character patterns, they are put in one block by the batch processing mechanism 7 of the host computer 1 and sent to the host computer 1. The batch processing mechanism 8 of the host computer 1 receives plural blocks of secondary external characters and the external character processing mechanism 6 searches an external storage device for the corresponding graphic character pattern and transfers it to the cluster device.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention detects graphic characters corresponding to graphic character patterns that are not held in the input/output device subsystem all at once in a host computer, and converts the graphic characters into This invention relates to a custom character processing system that transfers corresponding graphic character patterns to an input/output device subsystem &C.

[Conventional technology]

The external character processing system that processes graphic characters such as kanji and kanji consisting of character codes of 2 or more bytes consists of an input/output device subsystem consisting of a host computer, a cluster device, and a terminal device connected to it. Among the graphic character patterns for characters, frequently used graphic character patterns are stored in the storage area of the input/output device subsystem or input/output! ! The remaining graphics and character patterns are stored in an external storage device 11ic connected to the host machine. Here, the graphic character corresponding to the graphic character pattern held by the terminal device in the input/output device subsystem is the same character, and the graphic character corresponding to the graphic character pattern held by the cluster device is the primary external character.

The graphic characters corresponding to the graphic character patterns held in the host computer are called primary external characters.

Conventionally, this type of external character processing system was shown in Figure 1.In Figure 6, (1) is a host computer including a main storage, a central processing unit, and an external storage, and (2) is a host computer (1). ) IC-connected cluster device, (J
) is a display device connected to the cluster device (2),
flI) is a printing device connected to the cluster device (2). fil is a custom character processing mechanism that processes custom characters in the cluster device (2), and (6) is a custom character processing mechanism that processes custom characters in the cluster device (2).
1) This is a custom character processing mechanism that performs custom character processing within.

Next, the operation will be explained. 7 Display device that handles graphic characters or t characters consisting of λ bytes fit+, 71 'P
When a graphic character corresponding to a graphic character pattern not held by the above-mentioned device is generated in the printer (printing device), the private character processing mechanism (yo) for the private character of the cluster system # (λ) is activated as the first private character processing. Search for a graphic character pattern to be held by the cluster device (λ). If there is a graphic character (primary external character) for which there is no corresponding graphic character pattern among the graphic character patterns held in the cluster device (2), the secondary external character is sent to the host computer f1) in units of 7 graphic characters. request the return of the corresponding graphic character pattern. As a result, the external character processing mechanism (6) of the host computer f1) is activated, receives secondary external characters in units of graphic characters from the cluster device (2), and processes them from the external storage device (not shown) of the host computer l. Look for graphic character patterns. When a graphic character pattern corresponding to a primary external character is found, the graphic character pattern is transferred from the external character processing mechanism (6) of the host computer (1) to the external character processing mechanism (j) of the cluster device (2). Next, the cluster device -) generates the primary external characters from the display device (3).
) or printing device fit (4'l K is transferred and displayed or printed.

[Problem that the invention seeks to solve]

Conventional external character processing systems are configured as described above, so that during display or printing on a display device (3) or printing device [f4'1 When a graphic character is generated, $1 primary external character is sent from the cluster device (2), and the primary external character is sent from the host computer f1) to the graphic character pattern corresponding to the graphic character.
Display device ji (3) or printing device fl f for each graphic character
It was necessary to display or print by transferring to fl.

In particular, in the processing of primary external characters, graphic character patterns are transferred from the host computer (1) in units of graphic characters, so the waiting time for displaying or printing primary external characters is longer than that for internal characters or primary external characters. There was a problem that it became long and it was difficult to see due to variations in display or printing speed.

Also, the external character processing mechanism (6) in the host computer (1)
Since the system receives and processes primary external characters in units of graphic characters from the cluster device (2), the number of inputs and outputs in the host computer (f/) increases, which increases the load on the host computer (f/).

This invention was made in order to eliminate the learning points of the conventional custom character processing system as described above, and it is a custom character processing system in which the display or printing speed trap of the primary custom character is the same as that of the primary custom character. is intended to provide.

[Means for solving inter-group points]

The technical means adopted in this invention to achieve the above object include an input/output device subsystem consisting of a cluster device and a terminal device connected thereto; In a custom character processing system consisting of a host computer having an external storage device that holds custom characters, which are graphic character patterns, the cluster device can process the display or When the print data includes a plurality of the above-mentioned external characters, the host computer is equipped with a batch processing mechanism that extracts only the above-mentioned external characters and transfers them in 1 block K to the above-mentioned host computer. The apparatus is characterized by comprising a batch processing mechanism that receives the blocks of the foreign characters that have been created in bulk, searches the external storage device for graphic character patterns corresponding to the foreign characters, and returns them all at once to the cluster device. This is Atsunari.

[For production]

In this invention, a display device, a printing device, or a cluster device that processes one graphic character holds (among graphic characters that correspond to a graphic character pattern that does not exist).

The primary external characters are collected for each terminal device within the cluster device,
After the host computer processes the secondary external characters all at once,
Figure 1 character patterns are collected in units of terminal devices and transferred from the host computer to the cluster device.
