Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interface switching control device for a monitoring device of a computer organization, and particularly relates to a plurality of N central processing units and corresponding N central processing units divided into a plurality of systems. This invention is applied when an arbitrary combination of connections between each central processing unit and each set of peripheral devices is required in a computer organization composed of sets of peripheral devices.

Figure 1 shows an example of a computer organization, which has four central processing units 1, P1, P2, P3, and P4, and four peripheral devices 3, I1, I2, I3, and I4, and each peripheral device. In this example, four interface switches 2, S1, S2, S3, and S4, are provided. In the above computer organization, S1 of the interface switch 2 is P of the central processing unit 1.
1 and I1 of peripheral device 3 are connected. Similarly, S2 sets P2 and I2 to S
3 closes the circuit so that R3 and I3 are connected, and S4 connects P4 and I4. As a result, the four central processing units 1 and four sets of peripheral devices 3 divided into two systems (0 system, 1 system) are connected in predetermined combinations.

The connection between the central processing unit 1 and the peripheral device 3 is as follows.
First, at the start of operation, it is necessary to connect once in a predetermined combination. Generally, switching instructions for connecting in a predetermined combination include fixed switching, batch switching, and pattern switching.
Next, at the start of or during operation, some peripheral devices 3
The combination may be changed. This switching of some of the peripheral devices 3 is called individual switching. 1st
In the figure, these switching controls are specified from the operation unit of the monitoring device (SUP) 4.

FIG. 2 shows a block diagram of the monitoring device 4. The operating section consists of a cathode ray tube display device 8, a keyboard 12, and a light pen 16, and a floppy disk 13 is used as an external memory. Note that the control is assumed to be program controlled using the microprocessor 5. Below, as an example, P1 of the central processing unit 1 is I1 of the peripheral device 3, and similarly P2 is I1 of the peripheral device 3.
2. Start operation with fixed switching connecting P3 to I3 and P4 to I4, and halfway through, connect P2 and I2 to P
The procedure for switching to the connection between 4 and I2 will be explained. FIG. 3 shows the switching procedure in that case, and FIG. 5 shows the table specifications.

The following description assumes that the switching mode is designated using the keyboard 12 and the switching instruction is performed using the light pen 16. When the fixed mode is designated from the keyboard 12, the contents of the fixed mode area of the floppy disk 13 are loaded into the memory 6. The fixed mode switching pattern is the contents of TBLX in FIG. The cathode ray tube display device 8 has this TBLX
connection status is displayed. This movement is shown in Figure 3a. Next, when a switching instruction is issued from the light pen 16, the interface switch 2 is switched according to the contents of TBLX. This movement is shown in Figure 3a. Operation starts with this combination, but next, connect P2 and I2 of central processing unit 1 to P
Suppose that it becomes necessary to switch to 4 and I2. In this case, when the individual mode is designated from the keyboard 12, the contents of the individual mode area of the floppy disk 13 are loaded into the memory 6. This movement is the third
Shown in Figure b. Individual mode switching pattern
TBLY is each interface switch S1, S2,
Although the areas S3 and S4 are secured (TBLY-(1) in FIG. 5), the state of the interface switch 2 at that time is read and TBLY-(2) is created. This movement is shown in Figure 3b. The connection status of TBLY-(2) is displayed on the cathode ray tube display device 8. This movement is shown in Figure 3b. Seeing the connection status displayed on the cathode ray tube display 8, the operator issues an instruction to switch S2 from the keyboard 12 or light pen 16, and TBLY-(3)
and create TBLZ. This movement is shown in Figure 3b. Next, when a switching instruction is issued from the light pen 16, S2 of the interface switch 2 is switched according to the contents of TBLZ. This movement is shown in Figure 3b.

The above is conventional switching control that is generally performed. Now, if we consider turning off the power and restarting operation according to the contents of TBLY-(3), the situation will be as follows. That is, (1) Execute the steps a and b in Figure 3.

(2) TBLY - Prepare a switching pattern table corresponding to (3) and execute the procedure a in Figure 3.

By either method (1) or (2) above,
In order to deal with various computer organization configurations, a large number of tables corresponding to the switching pattern TBLX are required. On the other hand, the switching mode generally has only a few modes such as batch switching and pattern switching. In large-scale computer organizations, there is a need to simplify initial settings and batch switching operations, speed up switching, and reduce operational errors. Therefore, the conventional methods lack the ability to diversify the configuration of computer systems, speed up operations, and ensure reliability.

An object of the present invention is to provide a control device that speeds up conventional operations and eliminates the lack of reliability, and enables quick and reliable switching in any configuration, as the configurations of computer organizations become more diverse. It is in.

The present invention registers combinations of connection states between the central processing unit and peripheral devices during operation on a floppy disk, etc. at any time, and switches according to the registered combinations, thereby ensuring quick and reliable switching of any desired configuration. It is characterized by carrying out the following.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 4. FIG. 4 shows an example of the operation of the present invention.

When you specify the individual mode from the keyboard 12,
The contents of the individual mode area of the floppy disk 13 are loaded into the memory 6. At the same time, it reads the device status and creates a switching pattern table. The cathode ray tube display device 8 displays the status of the device. The state of the device at this time is shown in Figure 5 TBLY-(2)
shall be. Here, suppose that P2 of the central processing unit 1 has a failure, so I2 of the peripheral device 3 is switched from P2 to P4. In this case, the display content on the cathode ray tube display device 8 is corrected and a switching instruction is given using the light pen 16. The movements up to this point are shown by ~ in Figure 4 b'. This is exactly the same as conventional individual switching. When a new mode registration instruction for the individual mode is issued using the light pen 16, a switching pattern TBLY-(3) corresponding to the state of the device is written in the auxiliary mode area of the floppy disk 13. Floppy disk 13 auxiliary mode is keyboard 1
By instructing the auxiliary mode from 2, the data can be loaded from the floppy disk 13 to the memory 6. This movement is shown in Figure 4c. This is the same procedure as conventional fixed switching.

As a result, a table to be displayed on the cathode ray tube display device 8 can be registered on the floppy disk 13 in the individual mode without the operator creating a switching pattern table corresponding to the device status. Furthermore, through the above registration, any irregular configuration can be initialized as a predetermined configuration.

As is clear from the above description, the following effects can be obtained according to the present invention.

(1) Creation of switching pattern tables such as fixed switching, batch switching, pattern switching, etc. is based on input instructions from the operator. In the present invention, the switching pattern table is created based on the state of the device, and only some corrections are made by the operator, so that the switching pattern table can be created quickly and reliably.

(2) Even if the configuration is irregular due to a failure, etc., if it is registered, operation can be started using the same switching control procedure as fixed switching.

(3) By making it possible to register switching patterns,
Eliminates operator intervention during individual switching,
Automatic start-up is possible.
