Abstract

PURPOSE:To easily control plural graphic processors with a single graphic output controller with no consciousness of the difference of those graphic processors by converting a standard command into a device proper command read out of a command file and applying the device proper command to the graphic processors. CONSTITUTION:An instruction control part 21 receives an instruction from an operator for a subject graphic processor and inputs a standard command via a graphic output controller 10. An instruction is given to a file control part 22 for a specific command file 40 to be used. Then the part 22 reads a device proper command out of the file 40. A command converting part 23 converts the standard command into the device proper command and outputs it to a graphic processor 30. Then the action is repeated with presence of the standard command, while the operation is through with absence of the standard command.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is applied to a graphic processing device control system of an information processing device. In particular, it relates to a device-specific control system that handles graphic processing devices with different attributes.

〔overview〕

The present invention provides a graphic processing device control system in which device-specific commands corresponding to a plurality of graphic processing devices are stored in a command file, and instructions are issued from the command file based on an operator's instructions for the target graphic processing device. By reading the corresponding device-specific commands of the graphics processing device, converting the standard commands, and giving them to the designated graphics processing device, you can control one graphic output without having to be aware of multiple graphic processing devices with different attributes. It is designed to be easily controlled by a device.

[Conventional technology]

Conventionally, graphic processing control systems have required a graphic output control device for each target graphic processing device.

[Problem that the invention seeks to solve]

However, such conventional graphics processing device control systems have the disadvantage that each graphics processing device must have a graphics output control device because it is specific to each graphics processing device.

The present invention solves the above-mentioned drawbacks, and aims to provide a graphic processing device control method that can be easily controlled by a single graphic output control device without being aware of multiple graphic processing devices having different attributes. shall be.

[Means for solving problems]

The present invention provides a graphics processing device control system that includes a command file storing device-specific commands corresponding to each graphics processing device, and a command expansion processing device, wherein the command expansion processing device is configured to control a target graphics processing device. an instruction control unit that manually inputs instructions and standard commands, and a file control unit that reads out a device-specific command corresponding to the instructed graphics processing device stored in the command file based on the output of the instruction control unit; The present invention is characterized in that it includes a command conversion section that converts the standard command into the read device-specific command, and an output control section that provides the output of the command conversion section to the designated graphic processing device.

[Effect]

Device-specific commands corresponding to each graphic processing device are stored in a command file. The command control unit of the command expansion processing device inputs instructions and standard commands of the target graphic processing device from the operator. The file control section reads out the device-specific commands of the designated graphics processing device stored in the command file based on the output of the command control section.

The command converter converts the standard command into the read device-specific command. The output control section provides the output of the command conversion section to a designated graphic processing device. By the above-described operation, one graphic output device can easily control a plurality of graphic processing devices having different attributes without being aware of them.

a file control unit 22 that reads out the device-specific command corresponding to the instructed graphic processing device 30 stored in the file 0;
It includes a command conversion section 23 that converts the standard commands into the read device-specific commands, and an output control section 24 that provides the output of the command conversion section 23 to the instructed graphic processing device 30.

The operation of the graphic processing device control device having such a configuration will be explained. FIG. 2 is a flow chart showing the operation of the graphic processing device control device of the present invention.

In FIGS. 1 and 2, the instruction control unit 21 receives instructions for the target graphic processing device from the operator (
Sl), and a standard command is input from the graphic output control device 10 (S2). The file control unit 22 is instructed which command file 40 to use, and the file control unit 22 reads the corresponding device-specific command from the command file 40 based on the graphics processing device instructions and standard commands (S3).

The command conversion section 23 converts the standard command received from the graphic output control device 10 into a device-specific command and passes it to the output control section 24 (S4). The output control unit 24 outputs the received device-specific command to the target graphic processing device 30 (S5). If there is a standard command (S6)
, returns to step S2 and repeats the above-described operation. If there is no standard command (S6), the process ends.

FIG. 3 is a diagram showing the record format of the command file of the graphic processing device control device of the present invention. In Figure 3,
The index section 51 stores standard commands and serves as an index (key) for searching the command file 40 for a corresponding device-specific command. Number of device-specific commands: 52
