JPS59139432A - Expansion system of form overlay and data - Google Patents

Abstract

PURPOSE:To shorten the expansion time of form overlay and data, by leaving a form overlay pattern, which is expanded once,expanded on an image memory as it is, until the next differenct form overlay is indicated. CONSTITUTION:Data of form overlay of FOV are registered in an FOV register area, and data to be overlaid on FOV patterns are registered in a data storage area. FOV data is read out and is expanded on an image memory 24. Next, data is read out and is overwritten onto a memory where FOV expansion is already performed. The FOV pattern expanded on the image memory 24 and overwrote graphic character data are sent to an output buffer and are printed. If a new order (change of FOV) does not exist after printing, contents of the image memory 24 is not cleared, and the control is returned to a data read process to process next data.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a form overlay and data development method for an image memory in an information processing device.

(2) Background of the technology The form overlay and data expansion method in an information processing device reads a pre-registered form overlay pattern and expands it into an image memory (memory to which addresses are added two-dimensionally).
This is done by reading data (numbers, characters, etc.) and overwriting it on the previously developed form overlay pattern.

Figure 1 shows the 7 ohm overlay and data developed in the image memory and the central processing unit (CP) for them.
The data streams from U) are shown side by side. 1st
Figure (1) illustrates a completed i4' turn. In the figure, the characters for terms and product names and the solid line frame are developed form overlays, and the numbers and alphanumeric characters are data.

FIG. 1(2) illustrates the development of the Form Oni Valley. The signal (data stream) sent from the CPU has a part 3 that displays the byte length, as shown on the left.

Figure (3) shows the development of data (in text, numerical values).

As shown on the left side of the figure, the data stream regarding data includes a byte length display section 34, a data display section 35,
There are two versions: one with a part 36 for specifying the base address of data, and the other with a data table storage part 37 in place of the base address designation part 36. Data from these data streams is expanded into the image memory to fill in the blanks within the solid box shown on the right.

(3) Prior Art and Problems FIG. 3 is a flowchart summarizing the conventional method of the above-mentioned form overlay and one-time expansion. That is, "Fov registration", "data registration", r
The following steps are performed: ``FOV reading'', ``r FOV expansion'', ``data reading J, overwriting rrov expanded expansion memory memory'', ``sending out output buffer 7 ahe'', ``clearing sending line'', and ``printing end''. In this case, when printing is completed, the entire image memory is erased by a process called "clear sending line", and the process returns to the process of "reading l'-FOV" to perform the next development. In general, printing by form overlay is performed on multiple sheets, and it is thought that only the data is changed and developed each time. Therefore, with the conventional method of erasing the form overlay pattern from the image memory each time it is printed, the form overlay must be developed each time data is updated, which poses a problem in reducing development time. ing.

(4) Purpose of the Invention In view of the problems in the conventional method described above, the purpose of the present invention is to keep the 7-ohm overlay pattern developed once in the image memory until the next instruction for a different form overlay is received. Based on this concept, the purpose is to eliminate the need to erase form overlays that are performed every time data is expanded, and thereby to completely shorten the time required to develop the form overlay and data. (5) Structure of the Invention In the present invention, in the form overlay and hitator development method for the image memory in the information processing device, the form overlay buffer! llll form overlay data is stored in the image memory to develop a 7-ohm overlay pattern, and then the character data of the digraph ink is read from the graphic page buffer and overwritten on the form overlay pattern, and the overwritten pattern and data are Then, without erasing the form overlay pattern in the image memory until the form overlay pattern is updated, character data of the next graphic to be written is read from the graphics page buffer. A form overlay and data development method is provided which is characterized by repeatedly performing an operation of overwriting the data and sending it to an output buffer.

(6) Embodiment of the Invention A 7-om overlay as an embodiment of the invention is shown. In FIG. 4, data signals from the CPU are routed through a standard serial interface (not shown) to a serial interface control attachment (Sifc A).
TT) 11, 5lfcATT 11 is a serial interface (Sifc) control circuit 12, read buffer 13, work buffer 14, graphic page buffer 15, image buffer 1.6, FO

connected to. The read buffer 13 responds to the CPU side with a signal indicating the status of the device. The work buffer 14 is C
Analyzes the data from the PU and stores the graphics page buffer 15, image buffer 16, FOv buffer 17,
Or, assign it to either the character page buffer 718. The data allocated to any of the buffers 15 to 18 is sent from the common control circuit 19 through the respective control circuits, namely, the graphic control circuit 20, the image control circuit 21, the overlay control circuit 22, and the character control circuit 230. Take control.

Data controlled by any one of the control circuits 20 to 23 is stored in the image memory 24.

The data stored in the image memory 24 is printed by a printing mechanism (PM) 27 via a print control attachment I-(PRCATT) 26 which is controlled by a PRC control circuit 25.

Referring to FIG. 5, the development procedure in this embodiment will be explained.

First, FOV data is registered in the FOV registration area. Next, the data to be overwritten on the FOV i# turn (for example, graphic character data) is registered in the data storage area (for example, graphic page buffer 7 area).
5).

Next, the registered FOV data is read out and developed into the image memory 24. Next, data (for example, graphic character data) is read out, and the memristor is overwritten on FOV expansion. The FOV/e-turn and overwritten graphic character data developed in the image memory 24 are sent to the output buffer,
printed. Even after printing is completed, if there is no new order (FOV change), the image memory 24 is not cleared, and the process returns to the process of reading data (for example, graphic character data) to process the next data.

When there is a change in FOV, the image memory 24 is completely cleared and processing starts from the FOV registration step.

In this way, when there is no change in the FOV number four turns, compared to the conventional method, the steps of successive FQV deployment and F'OV deployment can be omitted, and the time required for deployment can be shortened. In addition, since the FOV pattern is not actually changed and only the graphic character data is frequently updated, this method is highly effective in reducing time.

FIG. 6 illustrates the comparison of the development times described above.

FIG. 6(1) shows an example of the required time in the case of the conventional method. In both cases, graphic character data is developed twice for the same FOV pattern.

(7) Effects of the Invention According to the present invention, the form overlay A developed on the image memory is performed every time data is developed.
'Turn erasure is not performed until the 7 ohm overlay pattern is updated, thereby shortening the shift ohm overlay and data development time.
