Abstract

PURPOSE:To improve the reliability of an information processor by accepting and displaying a parameter for indicating next processing even during the execution of processing. CONSTITUTION:A control circuit part 201 when recognizing the execution of processing which is requested before calls a keyboard input control processing circuit 202. The keyboard input control processing circuit 202 checks whether or not a user keys in data. When so, input character code is read and transferred to a character drawing circuit, and a return key is hit so as to inform the control circuit part 201 of the execution of character input. Further, the control circuit part 201 when recognizing the key-in operation calls a character drawing control processing circuit 203. The character drawing control processing circuit 203 sets a necessary parameter such as the character code in the character drawing circuit and starts drawing the character. This flow returns to the control circuit 201 unless the character code is transferred.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an information processing device that electronically handles image information for recording, reproducing, and transmitting image information.

(Prior art) In recent years, the number of devices that handle image information, such as copying machines, facsimiles, word processors, and electronic file devices, has increased, and the efficiency of document handling in offices has improved, creating an environment where it is easier to obtain high-quality information. It's getting sorted. however,
On the other hand, with the increase in OAA equipment, each office floor
J The handling of OA equipment has become complicated. Therefore, there is a desire for an OA system that can perform document processing in an integrated manner. As such an integrated OA system, a patent application was made in 1986.
0-142115 is disclosed.

(Problems to be Solved by the Invention) Although the above-mentioned conventional devices have improved the handling of image information, they are not necessarily satisfactory from the viewpoint of operational performance. For example, when inputting image information from a scanner, outputting image information to a printer, or exchanging images via an external communication system, the user may continue executing the next process. Even if you try to give instructions, you cannot give instructions for the process, and furthermore, you cannot respond to the user. In particular, when a user tries to enter parameters for the next process using a keyboard, the device does not accept the input, or even if the parameters are accepted, the parameters cannot be displayed. This may become a major flaw in some cases when considering the operability of the device, and especially in devices that perform advanced processing, there may be various parameters that require confirmation from the user. Users have to wait until inputting the next instruction until the command is completed, which seriously degrades operational performance.

Therefore, an object of the present invention is to provide an information processing apparatus that can instruct and confirm the next process even when a certain process is being executed on information via a communication line.

[Structure of the Invention] (Means for Solving the Problems) According to the present invention, a communication input means for inputting information via a communication line, a control means for controlling the communication input means,
A parameter input means for inputting desired parameters, a processing means for converting the parameters input by the parameter input means into a character signal, and a display for displaying information of the communication input means and the character signal converted by the processing means. An information processing apparatus is provided, comprising: a control means; and a management means having a function of processing the control means and the processing means in parallel.

[Operation] During execution of the first instructed process, for example, inputting information from the communication input means, parameters for instructing the next process are input by the user from the input means. These instruction parameters are displayed on the display means together with the input information from the communication input means, and even while one process is being executed, instructions for the next process can be given.
The operability of the information processing device is improved.

[Embodiment] According to the circuit of the information processing device, that is, the image processing device shown in FIG. This system bus 11

is connected to the scanner 107, controls the scanner 107 according to instructions from the central control unit 101, and controls the scanner 107.
It has a function of transferring image data of image information read by the image bus 114 to the image bus 114. Optical disk reading section 1
04 is connected to the optical disk device 108, and the central control unit l
It has a function of controlling the optical disk device 108 according to instructions from the optical disk device 108 and transferring image data transferred from the optical disk device 108 to the image bus 114. The communication input unit 105 is connected to an external communication cable 115 and has a function of transferring image data transferred from the outside to the image bus 114 according to instructions from the central control unit 101. The keyboard input unit 106 has a function of notifying the central control unit 101 of data entered using the keyboard 117.

The character drawing circuit 11ft has a character pattern generation circuit that generates a character pattern, selects a character pattern under the control of the central control unit 101, and outputs the character pattern to the image display storage unit 102 according to the sequence of drawing one character. The image display storage unit 102 is composed of a dual port memory that can access two types of data simultaneously. In this access, two two-dimensional address generation circuits (2
The image data accessed and read by the addresses from D-AGC) 111 and 112 is sent to the display control circuit 10.

, an optical disk reading section 104 and a communication input section 105.

FIG. 2 shows a systematic configuration of the device shown in FIG. 1 from the viewpoint of software. According to this diagram, the management circuit section 201 is shown corresponding to the central control section 101,
Similarly, the keyboard input control processing circuit 202, character drawing control processing circuit 203, image human power control processing circuit 204, optical disk reading control processing circuit 205, and communication human power control processing circuit 20B respectively include the keyboard input section 106, the character drawing circuit 116, and the image Input section 103, optical disk reading section 104
, corresponds to the communication input section 105. The other control processing circuit 299 corresponds to other input/output circuit devices.

Next, the operation of the embodiment will be described with reference to the flowcharts of FIGS. 1, 2, and 3. Management circuit section 201
When the start of operation, the management circuit section 201 first activates the control processing circuits (202 to 299) necessary for the processing.

Specifically, the management circuit unit 201 sets flags of necessary processing control circuits in the table shown in FIG. 7 to ON. Thereafter, the management circuit unit 201 sequentially searches the table according to the flow shown in FIG. 3, and calls (CALL) the control processing circuit whose flag is ON. For example, when the image input control processing circuit 204 is called, the image input control processing circuit 204 operates according to the flow shown in FIG. That is, when the image input control processing circuit 204 receives a call, first,
In response to this, it is checked whether there is an execution request from another party.

If there is an execution request, it is checked whether the previously requested process is currently being executed. If it is running,
The image input control processing circuit 204 enters a return flow to be in a standby state until the next call is made from the management circuit unit 201. If the process is not being executed, the image input control processing circuit 204 sets necessary parameters in the image input unit 103, instructs the start of execution, and notifies the management circuit unit 201 of the execution of the process.

When the management circuit unit 201 approves the execution of the image input unit 103, it calls the keyboard input control processing circuit 202, for example. When the keyboard input control processing circuit 20.2 receives the call, it operates according to the flowchart shown in FIG. That is, the keyboard input control processing circuit 202 checks whether data has been keyed in by the user. If keyed in, the input character code is read and
This code is transferred to the character drawing circuit 116 and returns to notify the management circuit section 101 of character input execution.

When the management circuit unit 201 recognizes the key-in, it calls the character drawing control processing circuit 116. When the character drawing control processing circuit 116 receives the call, it operates according to the flowchart shown in FIG. That is, first, the character drawing control processing circuit 1
Reference numeral 113 checks whether a character code has been transferred from the keyboard input control processing circuit 202 or not. If a character code is transferred, it is checked whether the previously requested process is being executed. If it is being executed, the management circuit unit 201
The return flow is entered to wait for the next call to be made from . If it is not being executed, necessary parameters such as a character code are set in the character drawing circuit 11.8, and the execution of character drawing is started. If no character code is transferred, the flow returns to the management circuit section 201.

As described above, the management circuit unit 201 always manages each control processing circuit, and when a called control processing circuit executes a requested process, it recognizes the execution and requests the processing to other control processing circuits. call.

That is, even if a certain process is being executed, it is possible to instruct another process. Therefore, it is possible to execute another process during the processing time required for one process, and two or more processes can be executed simultaneously and in parallel.

A dual port memory is used in the image display storage unit 102 to simultaneously execute the two processes described above in parallel. This dual port memory is shown in FIG. 8, where a memory 301 having a capacity larger than that required for display
(e.g., DRAM) and a marbiter that receives access signals for writing and reading from both via signal lines 306 and 307, and allocates write and read timing to both the character drawing circuit and the control processing circuit. Marviter 302 is coupled to ports 303 and 304 via signal lines 311 and 312, respectively. Ports 303 and 304 are data and address ports and are turned on and off by control signals input from the marviter via signal lines 311 and 312.

data/address buses 1 and 2 to ports 303 and 30
4 to the read modified write logic circuit 305, respectively. The read/modify/write logic circuit 305 temporarily reads out the contents of the memory 301, changes a part of the read contents, and updates the contents of the memory 301. Data obtained via the port 303 or 304 selected by the marviter 302 is used as the rewriting data and address.

Next, the operation of parallel processing of image information read from a scanner using a dual port memory will be specifically explained.

A scanner 107 reads image information on the document by line scanning. Image data is written to dual port memory 102 via image bus 114 for each line. In this case, in response to REQ2 from central control unit 101, ACK2 is returned and boat 2 is turned on. The image data transferred from the port 2 via the image bus 114 and the data/address bus 309 is sequentially transferred line by line via the read modified write logic circuit 305 to the write memory. D
RAM 3011: The image data to be written is sequentially read out line by line by the display control circuit 109, and is read out line by line by the display control circuit 109.
10 is input. The CRT 110 displays image data line by line as shown in FIG.

Upon receiving ACK2, the central control section 101 issues a CALL to each section. At this time, keyboard input section 1
When the character code corresponding to the desired parameter is input from 06, the character code is transferred to the character drawing circuit 116 via the system bus 113.

The character drawing circuit 116 uses an internally provided character pattern generation circuit to draw a character corresponding to the input code according to a sequence of drawing one character. In addition, the central control unit 101
transmits REQl to marvita 302, and marvita 302
turns on boat 1 in response to REQI. Therefore, characters are written into the dual port memory 102 one by one by the character pattern signal sent from the character drawing circuit 116. The characters in the dual port memory 102 are read out,
When input to the CRTIIO, the characters are displayed, for example, as characters representing commands, as shown at the bottom of the display screen in FIG. At this time, the image information of the document read by the scan 107 continues to be drawn line by line. Such parallel processing of image data and character drawing is performed by a two-dimensional address circuit 11 that can be accessed independently.
1 and 112 by addressing memory 102.

Next, the operation of parallel processing of image data of the optical disk device 108 will be explained.

The image information stored in the optical disk device 108 is read line by line by the optical disk reading section 104. Image data for each line is written to dual port memory 102 via image bus 114. In this case, in response to REQ2 from central control unit +01, ACK2 is returned and boat 2 is turned on. The image data transferred from the port 1-2 via the image bus 114 and the data/address bus 309 is sequentially sent to the DR line by line via the read modified write logic circuit 305.
Written to AM301. Image data written to the DRAM 301 is sequentially read line by line by the display control circuit 109 and input to the CRT 110.

The CRT 110 displays image data line by line as shown in FIG.

Upon receiving ACK2, the central control unit 101 issues a CALL to each unit. At this time, the keyboard input section 10
When the character code corresponding to the desired parameter is input from 6, the character code is transferred to the character drawing circuit 116 via the system bus 113.

The character drawing circuit 110 uses an internally provided character pattern generation circuit to draw a character corresponding to an input code according to a single character drawing sequence. In addition, the central control unit 101
transmits REQI to Marvita 302, and Marvita 302
turns on boat 1 in response to REQI. Therefore,
Characters are written into the dual port memory 102 one character at a time by a character pattern signal sent from the character drawing circuit 116. The characters in the dual port memory 102 are read out and input to the CRTllo, so that they are displayed as characters representing commands, for example, as shown at the bottom of the display screen in FIG. At this time, image data read from the optical disk 108 is continuously drawn line by line. Such parallel processing of image data and character drawing can be achieved by addressing the memory 102 using two-dimensional address circuits 111 and 112 that can be accessed independently.

Next, the operation when image information transmitted via the communication cable 115 is processed in parallel with input parameters will be described.

For example, image information transmitted from a facsimile or the like via the communication cable 115 is received by the communication input unit 105 . The communication input unit 105 transfers the received image information to the image bus 114 line by line. Image data for each line is written to dual port memory 102 via image bus 114. In this case, the central control unit 1
In response to REQ2 from 01, it returns ACK2 and turns on port 2. Port 2 to Image Bus 1
14 and the data/address bus 309 are sequentially written to the DRAM 301 line by line via the read modified write logic circuit 305. Image data written to the DRAM 301 is sequentially read line by line by the display control circuit 109 and input to the CRT 110.

The CRT 110 displays image data line by line as shown in FIG.

Upon receiving ACK2, the central control unit 101 issues a CALL to each unit. At this time, the keyboard input section 10
When the character code corresponding to the desired input parameter is input from 6, the character code is transferred to the character drawing circuit 116 via the system bus 113. Character drawing circuit 11
Reference numeral 6 draws a character corresponding to the input code according to the sequence of drawing one character by a character pattern generation circuit provided inside.

Further, the central control unit 101 transmits REQI to the marviter 302, and the marviter 302 responds to the REQI by transmitting the REQI to the port 1.
Turn on. Therefore, characters are written into the dual port memory 102 one by one by the character pattern signal sent from the character drawing circuit 11B.

The characters in the dual port memory 102 are read out and transferred to the CRT.
By inputting the command to 110, the command is displayed as a character representing a command, for example, as shown at the bottom of the display screen in FIG. At this time, image data is continuously drawn for each line sent from the facsimile via the communication cable 115. Such parallel processing of image data and character drawing can be achieved by addressing the memory 102 using two-dimensional address circuits 111 and 112 that can be accessed independently.

[Effects of the Invention] As explained above, according to the present invention, the user can input instructions or parameters for executing the next process even while displaying image information from the communication input section, and It is possible to draw and display characters, and various processes can be executed appropriately and efficiently while checking the key human power.
