Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to computer system I / O.
The present invention relates to an I / motion display method for displaying a motion status to a user.

[0002]

2. Description of the Related Art In a personal computer system such as a personal computer or a workstation that employs a multitasking operating system such as Unix, general user task processing becomes slow during I / O processing. In order to prevent the user from being anxious that the processing has been delayed, there are some which are provided with means for notifying the user that the I / O processing is currently being performed.

In the conventional I / O operation display system of this type, an indicator of a light emitting diode is provided in the main body of the computer so that the user is notified by lighting up during file access or network traffic.

[0004]

DISCLOSURE OF THE INVENTION The conventional I / O described above
In the operation display method, the user needs to look at both the computer main body and the display device, which imposes a burden. Also, because the user needs to look at both, the user is constrained to place the computer main body near the user. In addition, a light emitting diode and peripheral circuits are required only for display, and there is a problem in that the circuit mounting area and cost are correspondingly increased.

[0005]

An I / O operation display system according to the present invention includes an I / O controller, a CPU for inputting an interrupt signal from the controller, and a frame buffer for storing display display data written from the CPU. An I / O operation display method in a computer system that realizes a multi-window environment, the display apparatus displaying the contents of the frame buffer, operating under a multi-window system that realizes the multi-window environment, The I / O operation display window routine that is selectively activated by the user's designation to display the processing information of the I / O controller on the display, and that the I / O operation display window routine is activated Display window registration table registered by the system And a window routine for displaying a corresponding I / O operation, which is activated by an interrupt signal of the I / O controller, is registered in the display window registration table, the I / O is added to the multi-window system. It is characterized by including an interrupt processing routine for issuing an instruction to display an operation.

[0006]

The present invention will be described below with reference to the drawings. Referring to FIG. 2, which represents a hardware block diagram of an embodiment of the present invention, the present embodiment includes an I / O controller 1,
CPU3, frame buffer (hereinafter abbreviated as FRB 5),
It is composed of a D / A conversion unit 7 and a CRT display device 9. Reference numeral 2 is an interrupt signal, 4 is a memory bus, 6 is a raster scan read signal, and 8 is a video signal.

The interrupt signal 2 from the I / O controller 1 is input to the CPU 3. The CPU 3 writes the display data in the FRB 5 via the memory bus 4. The contents of the FRB 5 are read out as a raster scan read signal 6 at the timing of CRT display, converted into an analog signal by the D / A conversion unit 7, and the output thereof is displayed as a video signal 8 on the CRT 9. .

The window system 12 of the present invention operates on the above hardware system. Figure 1 shows the relationship between this window system and related interrupt processing routines.
Shown in. 10 is an interrupt processing routine, 11 is a display window registration table, 12 is a window system, 13
Is an I / O operation display window routine.

The interrupt processing routine 10 is activated by an interrupt from the I / O controller 1. When an interrupt occurs, the interrupt processing routine 10 checks whether or not a routine for displaying the corresponding I / O operation is registered in the display window registration table 11, and if registered, based on the information in the table. The indication display is communicated to the window system 12.

The window system 12 activates a corresponding I / O display window routine 13 on the basis of the transmitted instruction, and the routine displays a mark indicating that the I / O is in operation in one of the windows. The I / O operation display window routine 13 is activated and terminated by the user. When activated, the Windows system 12 registers that fact in the display window registration table 11.
Further, when it is finished, the corresponding entry registered in the display window registration table 11 is invalidated.

In the following explanation, an Ethernet work controller and a SCSI bus controller which is a file device bus will be taken up as the I / O controller 1. These I / O operations are common I / O called Show I / O.
It shall be displayed in the O operation display window routine. The state of the display window registration table 11 is shown in FIG. In this table, an address is calculated according to the type of I / O interrupt, and the entry corresponding to each I / O interrupt is accessed. The table entry is a flag field 14 that indicates whether the display window is activated.
And a communication port number field 15 representing the port number needed to communicate with the corresponding display routine.

Next, the I / O of the interrupt processing routine 10
FIG. 4 shows a flowchart of a part related to operation display.

In FIG. 4, 1. When the I / O interrupt occurs, the interrupt processing routine 10 first decodes the interrupt factor.

2. If the interrupt factor is I / O, the display window registration table 11 is checked, and if the activation of the display routine is registered, the window system 12 is notified of the display request instruction based on the port number of the contents of the registration table. To do. In this communication, the type of I / O in which the interrupt occurred, Ethernet work in this example, SCS
I is also transmitted to the window system 12 side.

3. After that, I / O interrupt processing other than display is performed.

Here, the order of display and interrupt processing other than display is not essential. There may be an operation example in which display is performed after interrupt processing other than display.

FIG. 5 is a partial flowchart showing the I / O operation display of the window system 12. The window system 12 and the I / O interrupt processing routine of the OS exchange control and information by means of communication between procedures. Upon receiving the communication, the window system 12 operates as follows.

1. The port number of the communication is decoded and the corresponding display routine is activated according to the result.

2. Show I / O, which is one of the I / O operation display routines, is started.

3. The Show I / O judges from the communication information whether the type of I / O is Ethernet work or SCSI bus, and informs the user during the corresponding I / O operation with a design as shown in FIG.

4. The display routine ends.

The position and size of the display shown in FIG.
It is freely specified at the time when the ow I / O is activated and at any time after the activation. The user can freely specify the start / end of the display routine and control it. The display window can be turned off in an environment where the display window is not needed for various reasons, such as being bothersome and unnecessary for designing a unique window for reducing the load.

[0023]

According to the present invention, since the I / O operation status is displayed on the display, the user can monitor the I / O operation only by looking at the display. Therefore, compared with the system in which an indicator such as a light emitting diode is provided in the computer main body as in the conventional device, 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. Yes ・ The problem of circuit area and hardware cost for indicators is solved. Also, a user who is concerned about the load for displaying can freely start / stop the display routine within the framework of a normal window system.
