Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work terminal display terminal control system for performing multi-window control.
The present invention relates to a display command processing method suitable for displaying multi-dimensional information such as images at high speed.

[Background of the Invention]

Conventionally, the format of processing commands at the display end is GKS.
(Graphical Kernel Syetem) is being standardized ("Functions of GKS" PIXEL No.14 pp83-95 by the Graphic Processing Research Group / Standardization Subcommittee). However, GKS is intended to standardize a command processing method that mainly has a display processing function for graphic processing.
In the display terminal control of the workstation that integrally processes a wide variety of data such as signal information from various input devices, switching processing of the processing target group (called a segment in GKS) occurs frequently, It was a problem.

[Object of the Invention]

It is an object of the present invention to provide a command control processing method for controlling heterogeneous data at high speed and efficiently in a display terminal device that integrally processes flows of heterogeneous data.

[Outline of Invention]

To achieve the above object, in the display control command processing according to the present invention, in the management table of display output elements, elements representative of all element groups (all representative elements) and elements representative thereof among data types ( Each type representative element is stored, and when it is determined that the display control command is common regardless of the element type, the processing of all the representative elements is performed, and when it depends on the type, the processing of the type representative element is performed. By adopting the method, the load of the change processing of the representative element is reduced and the integrated processing of the plural information is effectively performed as compared with the method of designating a single representative element.

Example of Invention

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a computer system for carrying out the present invention. In FIG. 1, 101 is an application program which is stored inside the computer and determines the output content, format, etc. of various information such as characters, figures, and images. The application program 101 may run in a computer stored in the display terminal device, or may run in a computer independent of the display terminal processing. In the latter case,
A display control command is sent to the terminal via a transmission line such as a communication circuit. In any case, the determined output content is sent to the terminal management unit 102 as a display control command. The terminal management unit 102 is functionally equivalent to each application program 1
A virtual terminal management unit 103 that manages a conceptual terminal (virtual terminal) given to each 01 and a physical (actual) terminal management unit 104 that manages physical display hardware. The display control command from the application program 101 is interpreted and processed by the virtual terminal management unit 103, and is exchanged with the display information of the real screen according to the display priority order among the application programs 101 and the like. The actual screen display information is sent to the physical terminal management unit 104, is exchanged with the necessary memory information or the like on the CRT display unit 105, and is output. The display command control processing of different data according to the present invention is performed by the virtual terminal management unit of FIG.
Performed at 103.

FIG. 2 is a diagram showing the internal functional configuration of the virtual terminal management unit 103 shown in FIG. The display control command is divided by the discriminating unit 201 into those related to display data and those related to display element management. In the former case, the display information type determination unit 202 next determines the type of display information. Further, the processing target element determining unit 203 determines the specific number of data to be processed in a certain type, and the display information creating unit 204
Display data is updated with. On the other hand, when the received instruction is related to display element management, the representative element setting / changing unit 205 updates the element management table 206. The element management table 206 includes a number of elements to be processed for each data type, a representative element registration table 207 that describes a representative element that is a common processing target regardless of the data type, and all display target data. There is an element group management table 208 for managing the elements by the element number.

FIG. 3 is a flow chart format to more specifically show the above-described processing. Further, FIG. 4 shows the format of data referred to by the processing temperature and an example of the contents of each table. The commands received in FIG. 3, 301, are described in the formation of FIG. 4, 401. That is, the control code S1 and the data type code S2 are placed at the beginning of the command content data. At 302, the control code S1 is discriminated, and the processing branches depending on whether the following command is for displaying data or updating the element table. When it is determined that the command is for displaying data, the element type to be processed is determined in step 303. Specifically, it is divided into element types such as character display, graphic processing, and image processing. Type code S2 = 0
It means that the following display command is not particularly limited to the data type, but is related to general display control (for example, a command to move the origin of the display element). In the processing of the command of the type code S2 = 0, in 304, data processing common to elements is performed. At this time, the representative element registration table 207 is referred to. In the example of FIG. 4, since the representative flag indicates the position of type 2, the target of common data processing is the No. 4 element which is the representative element of type 2. In the processing of the command of the type code S2 ≠ 0, in 305, individual display data processing is performed. Also in that case, the representative element registration table 207 is referred to, but the representative flag is ignored,
For example, for a command of type code 1, element No. 2 is the processing target (because the element number of the representative element of type 1 is 2 in the representative element registration table 207). Specifically, when a plurality of already displayed graphic elements are displayed (in the element group management table 208, the elements No. 1 and No.
(2 is a display element of the same type), meaning that when the received command indicates drawing a line segment, the position specification and data management after display are interpreted and processed as a member of element No. 2. To do. In this way, discrimination of display data,
After the processing target is identified, the display data is specifically generated in 306, and the data is sent to the actual terminal management unit in 307. Further, the command determined to be the element table update instruction in 302 is interpreted by the 308 element table update processing unit, and, for example, movement of the representative flag, representative element N
Processing such as o. setting / change is performed.

〔The invention's effect〕

As described above, according to the present invention, when the application program instructs the display terminal device to display different types of data, it is possible to adopt a uniform command format regardless of the type of display data. In addition, since it is not necessary to add the display target element identifier for each command, the terminal display process of the multiple information can be performed at high speed and with high reliability.
