Abstract

PURPOSE:To display an indicator for indicating that this is under input/output operation on the multiwindow of a display device. CONSTITUTION:An interruption signal 2 from an input/output controller 1 is inputted to a CPU 3. The CPU 3, through a memory bus 4, writes data for display in a frame buffer 6 and makes access to a display window registration register 5. The contents of the frame buffer 6 are read as raster data 7 at the timing of the display, converted to an analog signal at a D/A conversion unit 8 and displayed at the display device 10 as a video signal 9. An user can monitor the input/output operation by looking at the display 10 and visibility is improved since information is displayed at one position compared with the conventional cases of displaying the input/output operation by LED or the like at the case body of the main body of a computer. Also, the cost of a hardware can be reduced compared with the display of the LED.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input / output operation display method for a computer system, and more particularly to an input / output operation display method for displaying the status of the input / output operation to a user.

[0002]

2. Description of the Related Art A conventional input / output operation display method is Uni
In a personal computer system such as a personal computer or a workstation that employs a multitasking operating system such as x, the processing of general user tasks becomes slow during input / output processing, and the processing becomes slow. In order to prevent the user from feeling uneasy, some devices are provided with means for notifying the user that input / output is currently being processed. For example, there is a light emitting diode indicator in the computer body, which informs the user by turning on the light during file access or network traffic.

[0003]

The above-mentioned conventional input / output operation display method requires the user to see both the computer main body and the display device, which is a burden on the user and requires the user to see both. For some reason, the user must be constrained to place the computer main body near the user, and the light emitting diode and the peripheral circuit are required only for the display, which increases the circuit mounting area and cost. It has the drawback.

[0004]

An input / output operation display method of the present invention includes an input / output controller, a CPU for inputting an interrupt signal from the input / output controller, and the CPU.
In the input / output operation display method of a computer system which realizes a multi-window environment, the multi-window environment is provided with a frame buffer for storing display display data written from the display buffer and a display device for displaying the contents of the frame buffer. An input / output operation display window routine that operates under a multi-window system to be realized and is selectively activated by user's designation to display processing information of the input / output controller on the display device, and the input / output operation display A display window registration register in which the multi-window system registers that a window routine has been activated, and the input / output operation display window routine which is activated by an interrupt signal of the input / output controller and displays the corresponding input / output operation. But, If it is registered in the serial display window entry register is configured by including the interrupt processing routine instructs in to view the said input output operation to the multi-window system.

A conversion unit, 9 is a video signal, and 10 is a display device.

The interrupt signal 2 from the input / output controller 1 is input to the CPU 3. The CPU 3 writes display data in the frame buffer 6 and accesses the display window registration register 5 via the memory bus 4. The contents of the frame buffer 6 are
The raster data 7 is read at the display timing, converted into an analog signal by the DA conversion unit 8, and displayed on the display device 10 as a video signal 9.

FIG. 2 is a diagram showing an example of the input / output operation display window system of this embodiment. As shown in FIG. 2, 11 is an interrupt processing routine, 12 is a window system, and 13 is an input / output operation display window routine. The interrupt processing routine 11 checks whether or not a routine for displaying the input / output operation is registered in the display window registration register 5, and if it is registered, the display instruction is communicated to the window system 12. The window system 12 activates the corresponding input / output operation display window routine 13 based on the received instruction, and the input / output operation display window routine 13 sets a mark indicating that the input / output operation is in progress to one of the windows. indicate.

The user specifies whether or not the input / output operation display window is actually displayed on the multi-window screen. When the user instructs the display, the window system 12 displays the display window registration register 5
Set the bit corresponding to the input / output type for which display was instructed in. Further, when the user instructs to erase the display, the window system 12 resets the corresponding bit of the display window registration register 5.

In the following description, an Ethernet work controller and a SCSI bus controller which is a file device bus will be taken up as the input / output controller 1. These input / output operations are displayed in the common input / output operation display window routine 13.

FIG. 3 is a diagram showing an example of the contents of the display window registration register 5. As shown in FIG. 3, 14 is an Ethernet work indication registration bit, and 15 is SCSI.
This is a bus display registration bit. Interrupt processing routine 11
The window system 12 knows which port number is used to communicate with each other depending on the meaning of the bits of the display window registration register 5 and the type of input / output. That is, for example, when an interrupt from the Ethernet network occurs, the interrupt processing routine 11
Check the Ethernet work display registration bit 14,
If necessary, a message is sent to the window system 12 using the appropriate port number, and the window system 12 knows from the port number that it has sent a message regarding the display of the Ethernet network.

FIG. 4 is a flow chart showing an example of input / output operation display processing of the interrupt processing routine 11.
As shown in FIG. 4, in step 41, the interrupt processing routine 11 first decodes an interrupt factor when an input / output interrupt occurs. If the interrupt factor is input / output at step 42, the display window registration register 5 is checked at step 43. If the activation of the display routine is registered, at step 44 the window system 1
The display request instruction is communicated to the port 2 based on the port number corresponding to the interrupt factor. In this communication, the window system 12 side is also informed of the type of input / output in which the interrupt has occurred, or Ethernet work or SCSI in this example.

After that, in steps 45 and 46, input / output interrupt processing other than display and interrupt processing of other factors are performed. Note that the order of display and interrupt processing other than display is not essential. In some embodiments, the display is performed after interrupt processing other than the display.

FIG. 5 is a flowchart showing an example of input / output operation display processing of the window system 12. FIG. 6 is a diagram showing an example of the input / output operation display window of this embodiment. The window system 12 and the input / output interrupt processing routine of the OS exchange control and information by means of communication between procedures.
The window system 12 operates as follows when receiving communication.

First, in step 51, the communicated port number is decoded, and the corresponding display routine is activated according to the result. Then, in step 52, the input / output operation display window routine 13 is started. In step 53, the input / output operation display window routine 13 determines from the communication information whether the type of input / output is Ethernet work or SCSI, and the status during operation of the corresponding input / output is as shown in FIG. And tell the user.

The display position and size shown in FIG. 6 are freely designated at the time when the user gives an instruction for the input / output operation display and at the time thereafter, like the normal window of the window system 12. Also, the user can freely specify and control the start and end of the display of the input / output operation. That is, the display window can be turned off in an environment in which the display window is not required for various reasons such as being troublesome, reducing the load, and unnecessary due to unique window design.

[0016]

As described above, according to the input / output operation display method of the present invention, since the status of the input / output operation is displayed on the display device, the input / output operation can be monitored only by looking at the display. You can Therefore, by providing an indicator such as a light emitting diode in the computer main body of the conventional input / output operation display method, the user has to look at both the main body and the display, therefore it is necessary to put the main body and the display together. There is an effect that problems such as the circuit mounting area and the hardware cost for the indicator can be solved. Further, there is an effect that a user who is worried about the display of input / output operation can freely start and stop the display routine within the framework of a normal window system.
