Abstract

PURPOSE:To carry out the output of a text with high efficiency and in a short communication time by performing the output to an output device and the transmission of the text in parallel with each other after providing a transmitting text memory part to a post-processing part and a blocking buffer and a receiving text control part to a pre-processing system respectively. CONSTITUTION:When a text is sent to a terminal equipment 7 from a text memory part 6, the text stored in the part 6 is successively read out by a transmitting text control part 5 and sent to a pre-conversation processing system 1 in a post-conversation processing system 2. The part 5 stops temporarily to read the text out of the part 6 for each transmission of a fixed processing unit number. Then a response request text for restart of transmission is sent to a receiving text control part 3 of the system 1 and this response is awaited. The part 3 checks the received text and stores it temporarily in a blocking buffer 4 if the text is not equal to a response request text. Then the text is outputted successively to the equipment 7 at and after the head part of the text.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a text flow control method, and more particularly to a text flow control method in a multiple processing system coupled by communication means.

[Conventional technology]

In the conventional text flow rate control method, each time a divided processing unit of text is received from the post-processing system, the pre-processing system transfers it to an output device such as a terminal device whose output speed is slower than the receiving speed. When this output is completed, the next processing unit is received and this process is repeated.

[Problem that the invention seeks to solve]

In the conventional text flow rate control method described above, the pre-processing system alternately receives data from the post-processing system and outputs it to the output device for each text processing unit, so the text reception operation and the output to the output device are The operation is done in series,
It is not possible to receive text from the post-processing system while outputting to a device with a slow output speed.

In addition, in order to receive data from the post-processing system when the output to the output device is completed for each text processing unit, the reception waiting time (pre-processing system, post-processing system, or communication line ) is required for each unit of text processing, and even though the text transmission speed from the post-processing system to the pre-processing system is faster if the processing units are sent all at once, this transmission speed is The problem is that they are not being fully utilized.

SUMMARY OF THE INVENTION An object of the present invention is to enable text transmission for each text processing unit in a multi-processing system to be performed in parallel without having to wait during other operations, and to enable communication. An object of the present invention is to provide a text flow rate control method that can efficiently output text in a short time.

[Means for Solving the Problems] The text flow rate control method of the present invention is a text flow rate control method for a plurality of processing systems including a preprocessing system and a postprocessing system connected by a communication means. Every time a certain number of processing units of text divided into processing units are continuously sent from the processing system to the pre-processing system, a response is obtained as to whether it is possible to send the next continuous number of processing units. The post-processing system includes a transmission text control unit that transmits a response request text and waits for a response to the response request text, and a blocking buffer that temporarily stores the text received from the post-processing system until it is output to an output device. , and a reception text control unit that controls the blocking buffer, checks the empty state of the blocking buffer, and transmits a response to the response request text to the transmission text control unit.

〔Example〕

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

FIG. 1 is a block diagram of a conversation processing system showing one embodiment of the present invention. In FIG. 1, a prefix conversation processing system 1 is coupled to a postconversation processing system 2 via a communication line, and includes a received text control section 3 and a blocking buffer 4. As shown in FIG. The post-conversation processing system 2 includes a transmission text control section 5 and a text storage section 6. Further, the terminal device 7 is connected to the prefix conversation processing system 1.

Next, the operation of sending text from the text storage section 6 to the terminal device 7 will be explained in detail.

In the postscript conversation processing system 2, the text stored in the text storage section 6 is sent by the transmission text control section 5.
The information is sequentially read out and sent to the pre-conversation processing system 1 via a communication line. The transmission text control unit 5 temporarily suspends reading from the text storage unit 6 every time a certain number of processing units are transmitted, and transmits a response request text for resuming transmission to the reception text control unit 3 of the prefix conversation processing system 1. and waits for the response.

The received text control unit 3 checks the received text, and if it is not a response request text, temporarily stores it in the blocking buffer 4, and outputs the text to the terminal device 7 in order from the beginning.

FIG. 2 is a flowchart showing the processing procedure of the received text control section 3, and explains the above operation.

In FIG. 2, step 31. shows the operation in which the received text control unit 3 receives one processing unit of text 1- from the transmitted text control unit 5, and the received content is first checked in step 32 to see if it is finished, and if it is not finished (
If NO), then in step 33 it is checked whether the response request text consists of one processing unit, but if it is not a response request text (NO), it is assumed that it is an output information text, and then in step 34 blocking is performed. It is checked whether buffer 4 is full.

If the blocking buffer 4 is in a full state (YES), the blocking buffer 4 is in a full state in which not even a single processing unit can be accommodated, then the checking is repeated after waiting for a certain period of time as shown in FIG. If the blocking buffer 4 has a free space that can accommodate the received or processed unit and is not full (NO), the received text processing unit is temporarily stored in the blocking buffer 4 (blocked in the blocking buffer) and sent to the terminal device 7. The process waits for output to the text, and moves on to the reception operation for the next processing unit of text.

When the received text control unit 3 detects a response request text in the received text, it checks the free space in the blocking buffer 4 and if there is enough free space, the postfix conversation processing system 2
A response is made to the transmission text control unit 5.

This operation will be explained in FIGS. 2 and 3. Third
The figure is an explanatory diagram showing the relationship between the free area of the blocking buffer and the area occupied by a certain number of processing units of text.

In step 33 of FIG. 2, the response request text (YE
If S) is detected, it is checked in step 36 whether the blocking buffer 4 is sufficiently empty, that is, whether it has an empty area equal to or more than a certain number of text processing units.

In FIG. 3, it is shown that the size of the free space in the blocking buffer area 61 is M characters, and the number of fixed processing units of text 62 indicates that the number of fixed processing units of this text is m.
0M (mXn) indicating that the unit and one processing unit is n characters (i.e. step 36 is No
), then 0M≧mXn, which can be checked by waiting for a certain period of time as shown in Fig. 2 (i.e., step 36
is YES), in step 37, the reception text control unit 3 sends a fixed number of processing units (in units of m) to the transmission text control unit 5.
A response is made to the effect that the text can be sent, and the process moves on to the reception operation for the next processing unit of text.

When the transmission text control unit 5 receives this response, it resumes transmission regarding the next fixed number of processing units of text.

In parallel with these operations, the text temporarily stored in the blocking buffer 4 is output to the terminal device 7 in order from the processing unit of the previously received text.

In the above embodiment, m units of text are efficiently sent from the postfix conversation processing system 2 to the prefix conversation processing system 1 until the free space in the blocking buffer area 61 becomes M(mXn), and In parallel with this, an output operation to the terminal device 7 is performed.

Note that although the above-described embodiments show the case of a conversation processing system, the present invention is not limited to this, and can be used in various applications such as a document processing system and a text processing system.

〔Effect of the invention〕

As explained above, the text flow rate control method of the present invention performs the text communication operation and the output operation to the output device in parallel, and does not take a fixed number of processing units of text as an opportunity to output to the output device. Since the text is sent continuously and at high speed, the pre-processing system, post-processing system, or communication line does not have to wait for each unit of text processing due to other operations, and the communication time is short and the text is sent efficiently. This has the effect of providing an output control method.
