Abstract

PURPOSE:To construct an exclusive process controlling system for a device without successive discrimination of low order device by discriminating low order device identification information from high order device, and forming a designated low order device proper processing system forming code. CONSTITUTION:Low order device discrimination information from a high order device is discriminated by a discriminating means 10. A proper processing system setting means 16 forms a designated lower device proper processing forming code based on the low order device discrimination information discriminated by the means 10 using a table 14 for low order device. The code is written in a storing area 12 used in common for proper processing of each low order device of a system control program, and a processing system proper to the designated device is formed. Thereby, an exclusive process control system of the device can be constructed without successive discrimination of low order device even when one of low order devices is designated by a high order device and processing proper to the device is executed.

Description

[Detailed Description of the Invention] [Summary] When performing processing unique to one lower-level device arbitrarily specified by a higher-level device among a plurality of lower-level devices, the specified lower-level device performs processing based on the determined information. A processing system configuration code specific to the specified lower device is generated using the table for the lower device, and this code is written to a storage area shared by the processing specific to each lower device in the system control program to create a processing system specific to the specified device. Form a processing system. This results in
Sequential lower-level device discrimination can be eliminated, reducing memory capacity and improving processing efficiency.

[Industrial application field]

The present invention relates to a process control method, and more specifically, to a process control method that eliminates sequential lower-level device discrimination in processing specific to a lower-level device designated by a higher-level device.

In an information processing system, among multiple lower-level devices,
Some devices perform processing specific to one lower device arbitrarily designated by a higher device. For example, a printing system.

In such a system, discrimination processing for one device specified in the system program is essential.

[Conventional technology]

In a conventional printing system, as shown in FIG. 8, one of a plurality of devices 101, 102, .
It is configured to be connected to a device and perform processing specific to that device. The image processing system 30 specifies which one of the plurality of devices 101 is to be subjected to the above processing. It is the control program prepared in advance in the adapter that connects the designated device to the image processing system and executes the required processing.

The processing flow of the control program is shown in FIG. As shown in this processing flow, the connected device provided from the image processing system 30 is determined, and the common processing routine 1
After performing (initial settings, etc.), device-specific processing begins, but prior to that, it is necessary to sequentially identify connected devices based on the device determination results ((1) in Figure 9).

After that, the next device-specific process ((2) in Figure 8) is performed again.
), (31), but in this case also the 8th
Judgment processing similar to (11) in the figure is required. This judgment processing is also performed sequentially.

[Problem that the invention seeks to solve]

In the conventional system as described above, although it is connected to the image processing system 30 and performs device-specific processing,
The connected device must be sequentially judged for each device-specific process, which increases the number of rejections and takes time to reach the device-specific process, which is a factor that reduces processing performance.

In addition, the amount of programs increases, resulting in several problems, such as an increase in memory capacity.

The present invention was created in view of such problems, and even if any lower-level device is designated by a higher-level device and a process specific to that device is performed, the present invention can be performed without successive determination of the lower-level device. The purpose of this invention is to provide a processing control method that can construct a processing control system dedicated to the device.

[Means for solving problems]

FIG. 1 shows a block diagram of the principle of the present invention.

As shown in this figure, in a processing control method that causes a lower-level device-specific process to be lazily specified by a higher-level device, the present invention includes a determining means 10 for determining lower-level device identification information transferred from a higher-level device. a storage area 12 shared by the system control program for switching to processing specific to each lower-level device; a table 14 for each lower-level device for code generation information; and a lower-level device determined by the determining means 10. The device is configured to include a specific processing system setting means 16 that generates a specific processing system configuration code for a specified lower device using the table for the lower device based on the identification information, and writes the code into the storage area 12.

[For production]

The lower-level device identification information from the higher-level device is determined by the determining means 10. Using the lower-level device identification information and the device table 4, a specified lower-level device-specific processing system configuration code is generated. This code is written into the storage area 12 to form a specific processing system corresponding to the specified lower-level device in the lower-level device.

In forming this unique processing system, there is no need for sequential determination processing, which was conventionally necessary, for each device-specific process.

The label table 241 is used to load the generated code storage address (label address) to the table storage location indicated by pointer 1, and the code table 242 is used to load the generated code storage address (label address) to the table storage location indicated by pointer 2. It is used to store instruction codes (mainly Jump, Ca1l) and jump destination addresses.

These two tables correspond to the so-called table 14 in FIG. S52 is a step of loading the contents of pointer 1 (Pl). S54 is the content of pointer 2 < P 2

However, although this change requires changes in multiple locations, the following points are common to each location, so the processing module name DEV2-A (LABEL in FIG. 4) of device 2-specific processing 1:

When the image processing system 30, which is a host device, wants to process the device 2, the device number #2, which is the identification information of the device, is transferred from the image processing system 30 to the adapter 20.

In the control program processing of the adapter 20 that received the device number #2, the device number #2 is determined (32 in FIG. 3).

Based on the determined device number #2, label table 24. The pointer 1 of the code table 242 is set to its starting address P1, and the pointer 2 of the code table 242 is set to its starting address P2 (850 in FIG. 5).

The generated code storage address predetermined by the control program, in this step, the <PI>-LABEL 1 address, is loaded into the table storage location of the set pointer 1 (852 in FIG. 5).

Then, the code table 24□ specified by pointer 2
Content <P2> = Cal 1 (D-do) and the code table 24 2 units ahead from its pointer 2 (P2)
2 content <P2+2>=DEV2-A (starting address of processing module DEV2-A) is loaded into the general-purpose register 26 (852 in FIG. 5).

After that, the contents of the code table <Pl> and <p2+
The address calculation result using 2> is stored in the table storage location <P
2+1> and completes the specific processing system generation code, CALL DEV2-A in this step (856 in FIG. 5).

This unique processing system generated code, that is, the contents of the code table 242 (P2> and <p2+1>) are stored in the label table 241.

A default value is preset by the initial setting in .

After setting the above-mentioned specific processing system generation code, pointer 1 and pointer 2 are set to LABE in device 2 processing 1, respectively.
For device-specific processing (see S26 in FIG. 4) indicated by L2, pointer 1 and pointer 2 are set to P, respectively, to generate a specific processing system generation code similar to that described above.

Then, in response to the determination that Pl has not reached the table end, device-specific processing: Generates a specific processing system generation code for LABEL2.

give rise to a set.

Thereafter, similar processing is carried out, and when Pl reaches the table end, the system in FIG. 2 is changed to operate as a specific processing system for device 2.
