Abstract

PURPOSE:To ensure the highly efficient transfer of data, by transferring the command information corresponding to the pattern information through a main control part if the transmission request data shows prescribed pattern information and at the same time preparing the corresponding pattern information through a circuit adaptor. CONSTITUTION:When a data request is given from an adaptor 13 for image information, a new command is added to a command register 21 for the line data which contains the special information to perform writing with this command in place of the transfer of the line data. With this system just a byte suffices, and this can reduce the load of a communication controller 12. For an output of a sentence, the commands like WHL (white line) and SAM (SAME DATA), for example, are provided. When a data request is given, a corresponding command is produced if it corresponds to the above-mentioned command and in place of the transfer of data. The circuit adaptor 13 interprets this command and produces a desired data.

Description

DETAILED DESCRIPTION OF THE INVENTION (11) Technical Field of the Invention The present invention relates to a data transfer system, and in particular, to a data OL line that is specially designed to reduce the amount of data transferred between the main control section and the -1 corresponding section. -I receive information from the 4KllI main control section of the
It's t's 夷#1liI to issue to the IJ Ki-1 corresponding department.
(2) Conventional technology and points of interest When transmitting data to a computer using the conventional TGJ111, all data is I was transferring it via inbatshua. Therefore, there was a drawback in that a large load was placed on the main control unit and the 1g1#l compatible unit.

(3J Purpose of the Invention It is an object of the present invention to eliminate the problem caused by @ and to perform efficient data transfer.

(4) The purpose of this invention is to create a system in which the main controller transfers desired data in response to a request for transmission data from an m-adapter, in which transmission request data from an ITL adapter is transmitted in a predetermined pattern. In the case of information@q), the cocoon heavy main control S transfers the command information corresponding to the predetermined pattern information instead of transferring the data, and the adapter transfers the transferred command t#@ A data transfer method characterized in that a means is provided to analyze the data and write information about the pattern is provided (5).

◎And instead of transferring data from the adapter to a# where the data request interrupt occurred, if the above command is triggered, issue the command, and IIMiI adapter 1 will issue the +1M command. This method is applicable not only to communication control equipment/lc@ but also to other devices that use similar data transfer methods. (6) From the effects of the invention If you use one JA@Kx, the amount of data when using a Gl standard facsimile as an output terminal is 1 twin 15m x 115m line.

Therefore, the load on the communication control device is reduced. ■ Average the peak load when using the nodding system.

■ The processor of the general FFL controller can implement a low-level 66 layer that reduces interrupt processing thresholds.

■ It depends on whether it supports the special fast mode processing (for example, white line skip) of the 7-axis terminal.

■ By providing a command that indicates the same information as before, it becomes easier to enlarge the image vertically by one screen.
