Abstract

PURPOSE:To improve the development and maintenance of a program by obtaining the generation order and timing of an interrupt and each information at the time of generation. CONSTITUTION:On the generation of an interrupt, an execution control means 2 actuates an information register means 1. The information register means 1 registered the generation origin of the interrupt, the content of a high-speed memory and a register, and the generation order of an interrupt generation address and an interrupt service address or the like. An information output direction means 3 performs the direction through the operation of a user to fetch information registered by the information register means 1. An information output means 4 outputs the information registered by the information register means 1 according to the request from the information output direction means 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interrupt information management method, and more particularly to an interrupt information management method for managing information on interrupts that occur regularly or irregularly as an interface between a person and a computer.

[0002]

2. Description of the Related Art Generally, a computer system interrupt includes a software interrupt generated from a program,
There are hardware interrupts that occur regularly or irregularly from each device in the computer system. In the conventional interrupt information management method, a person judges whether the service is correct or wrong by looking at the execution result of those interrupt services and the operation of the device.

[0003]

At the present time, the general use of computer systems has increased, and as more sophisticated programs and sophisticated devices have been developed, the incidence of interrupts tends to increase, and new or more sophisticated software is required. With respect to interrupt services and hardware interrupts and their services due to the emergence of new computer functions or attached devices, the above-described conventional interrupt information management method uses the interrupt service execution results and the device operation, and Has a drawback that it is difficult to develop and maintain a large-scale program because it cannot judge the execution result and the operation of the program properly.

Further, the conventional interrupt information management method has a problem that it is difficult to visually confirm the execution result of the service and the operation of the apparatus, and the operation is insufficiently confirmed. ing.

An object of the present invention is to obtain the interrupt generation order and timing, and various information when they occur,
An object of the present invention is to provide an interrupt information management method capable of improving program developability and maintainability.

[0006]

The interrupt information management method of the present invention is for interrupt control in which the execution of a program is temporarily interrupted for some reason during execution of the program in a computer system, and another program is executed. In the interrupt information management method for managing interrupt information,
(A) Information indicating whether the cause of the interrupt is generated by the device or the program, the contents of the high-speed memory or register inside the central processing unit, and the temporary interruption place of the program being executed. Information registering means for registering an interrupt generation address and an interrupt service address, which is a location of a program to be executed next, in the order in which they are generated; An execution control means for activating the means, (C) an information output instruction means for giving an instruction by an operation to take out the information registered by the information registration means, and (D) according to a request from the information output instruction means, An information output means for outputting the information registered by the information registration means, and an interface between a person and a computer. As it is constituted by managing information periodically or occurs irregularly interrupt.

[0007]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the interrupt information management method of the present invention. The interrupt information management method of this embodiment manages interrupt information for interrupt control in which the execution of a program is temporarily interrupted for some reason while the program is being executed in the computer system, and another program is executed.

First, as shown in FIG. 1, the execution control means 2
Controls the execution of interrupt processing when an interrupt occurs,
The information registration means 1 has been started.

Then, the information registration means 1 has information indicating whether the cause of the interrupt is generated from the device or from the program, the contents of the high-speed memory and the register inside the central processing unit, and the information being executed. The interrupt generation address which is the temporary interruption place of the existing program and the interrupt service address which is the place of the program to be executed next are registered at any time in the order of occurrence.

On the other hand, the information output instructing means 3 gives an instruction by the operation of the user in order to take out the information registered by the information registering means 1.

On the other hand, the information output means 4 can output the information registered by the information registration means 1 in accordance with the request from the information output instruction means 3.

Therefore, the interrupt information management method according to the present embodiment is used as an interface between a person and a computer.
Information on interrupts that occur regularly or irregularly can be managed.

FIG. 2 is a flow chart showing an example of the operation of the information registration means 1 of this embodiment. Information registration means 1 of this embodiment
First, as shown in FIG. 2, in step 11, all register information is registered in the information buffer. In step 12, the cause of interrupt is identified by the number defined by each interrupt and registered in the information buffer.

Then, in step 13, the interrupt generation address, which is the return address of the program when the interrupt occurs, is checked and registered. Further, in step 14, the interrupt service address is checked and registered from the interrupt service table. After that, in step 15, the information buffer is updated so that the interrupt information that occurs next can be registered. Then, in step 16, control is transferred to the interrupt service.

[0016]

As described above, the interrupt information management method of the present invention can improve the developability and maintainability of a program by obtaining the interrupt generation order and timing and each information when the interrupt occurs. It has the effect of being able to.
