Abstract

PURPOSE:To reduce the program development value by starting a program of a data processor and visualizing the data read out of a main storage or a large capacity magnetic storage. CONSTITUTION:A visualization process control part 11 decides the place of a subject to be visualized within a command given from outside. Then the part 11 reads the corresponding information out of a dump data file 31 and performs a visualization process if the subject of visualization is included in a large capacity magnetic storage 3. While a debug monitor program 22 is started via the communication circuit (GP-IB) control parts 12 and 21 as well as a communication circuit 100 if the subject of visualization is included in a target machine 2. Then the corresponding information is read out of a main storage and a visualization process is carried out. Thus it is possible to visualize the contents of the main storage of the machine 2 and the dump data on the file 31. Then the development of each program is not required.

TECHNICAL FIELD The present invention relates to a visualization processing circuit, and more particularly to visualization processing of the contents stored in a main storage device of a computer of different types.

Conventional technology Conventionally, in this type of visualization processing, the storage contents of the main storage device of a heterogeneous computer (hereinafter referred to as a target machine) are read out and the contents are visualized, or the main storage device of the target machine is read out. Only one of reading dump data from a dump data file in which the memory contents are stored and visualizing the dump data is performed.

In such conventional visualization processing, only the contents of the main memory of the target machine are visualized, or the dump data of the dump data file is visualized. In any case, there is a drawback that each program must be developed to perform visualization processing.

FIG. 1 is a diagram showing the configuration of an embodiment of the present invention. In the figure, an engineering workstation (hereinafter referred to as workstation) 1 includes a large-scale magnetic storage device 3 in which a dump data file 31 is stored, and a display device 4 for displaying visualized data.

The workstation 1 also has a communication line (CP-IB;
general purpose
It is connected to the target machine 2 via a bus 100, and each GP-I B control section 12.21 exchanges data via this communication line 100.

The visualization processing control unit 11 of the workstation 1 stores data specified by external information in the large-scale magnetic storage device 3.
It is determined whether the target machine 2 exists in the dump data file 31 of the target machine 2 or in the main storage device (not shown) of the target machine 2, and read processing is performed according to the determination result.

That is, the visualization processing control unit 11
If data exists in the main memory of GP-
The debug monitor program 22 of the target machine 2 is activated via the IB control unit 12.21 and the communication line 100.

When this debug monitor program 22 is started, necessary data is read from the main memory by this debug monitor program 22, and the data is transferred to the GP-I B.
It is sent to the workstation 1 via the control section 12.21 and the communication line 100.

At the workstation 1, the visualization processing control unit 11 performs visualization processing on the data sent from the target machine 2, and displays the data on the display device 4.

Furthermore, if data exists in the dump data file 31 of the large-scale magnetic storage device 3, the visualization processing control unit 11 reads the required dump data from the dump data file 31, and performs visualization processing on the dump data. is performed and displayed on the display W4.

FIG. 2 is a flowchart showing the operation of one embodiment of the present invention. The operation of an embodiment of the present invention will be explained using FIG. 1 and FIG. 2.

When visualization processing is performed, an external command first specifies the location, start address, size, or dump file name of the visualization target.

As a result, in the workstation 1, the visualization processing control unit 11 determines the location of the visualization target of the command (step 41 in FIG. 2).

If the location of the visualization target of the command is the dump data file 31 (step 42 in FIG. 2), the corresponding information is read from the dump data file 31 based on the start address, size, and dump file name in the command,
It is set in a predetermined area (not shown) of the visualization processing control unit 11 (step 43 in FIG. 2).

Thereafter, the visualization processing control unit 11 performs visualization processing on the relevant information from the dump data file 31 (step 44 in FIG. 2), and the process ends (step 45 in FIG. 2).

Also, if the location of the visualization target of the command is the main memory of the target machine 2 (step 46 in Figure 2),
), the start address and size in the command are recombined into a format that can be interpreted by the debug monitor program 22, and the GP
- It is sent to the debug monitor program 22 of the target machine 2 via the IB control unit 12.21 and the communication line 100, and the debug monitor program 22 is activated.

When the debug monitor program 22 is started, the relevant information is read from the location indicated by the start address and size in the main memory, and the relevant information is transferred to the GP-I B.
It is sent to the workstation 1 via the control section 12.21 and the communication line 100.

In the workstation 1, the content is set in a predetermined area of the visualization processing control unit 11 (step 47 in FIG. 2).
.

Thereafter, the visualization processing control unit 11 performs visualization processing on the relevant information from the main storage device (step 4 in Figure 2).

In this way, the visualization processing control unit 11 determines the location of the visualization target in the external command, and if the location of the visualization target is the large-capacity magnetic storage device 3, the corresponding information is read from the dump data file 31. If the location of the object to be visualized is the target machine 2, the debug monitor program 22 is activated via the GP-IB control unit 12.21 and the communication line 100 and the corresponding information is read from the main storage. By performing the visualization process using a single program, it is possible to perform the visualization process of the storage contents of the main storage device of the target machine 2 and the visualization process of the dump data of the dump data file 31.

Therefore, since there is no need to develop each program, the amount of programs to be developed can be reduced.

As described in detail, according to the present invention, a host system having a large-capacity magnetic storage device and a heterogeneous system having a main storage device can be connected to each other depending on the location of a visualization target indicated in an external command. A program on the data processing device is activated via an interface bus that connects the data processing device with the data processing device to perform visualization processing of data read from the main storage device or from the large-capacity magnetic storage device. As a result, it is possible to visualize the storage contents of the target machine's main storage device and the dump data of the dump data file using one program, and the amount of program development can be reduced.
