Abstract

PURPOSE:To shorten the time up to the start of an analysis by introducing a conversational type memory analyzing means in an analyzing mechanism for interruption trouble. CONSTITUTION:When an interruption is initiated, an OS sets the interruption information in a saving area 10 for the interruption information and starts the interruption trouble analyzing mechanism 9. The an instruction analyzing means 1 is called and an interruption information input means 9 is called to fetch instruction information which causes the interruption from the saving area 10 and analyze it into elements. Then, operand information is taken out and the instruction information and operand information are edited into mnemonic format and displayed on a display device 12. Then, a register analyzing means 2 is read to take the contents of all registers and display them. Then the conversational type memory analyzing means 5 is read to decide whether or not there is a memory analytic process and when the presence of the process is specified, a conversation information input means 7 is called to display the contents of a specified memory.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an interactive interrupt information display method, and more particularly to an interactive interrupt information display method in an interrupt failure analysis mechanism of an operating system.

[Conventional technology]

Conventionally, the analysis of interrupt information in this type of interrupt failure analysis mechanism has been carried out by (1) outputting a list of memory dumps using a standard utility of the system, and having an experienced person analyze this list.

[Problem that the invention seeks to solve]

The conventional interrupt information analysis method described above always outputs a large amount of list even though only a small portion of the necessary information is needed, so it has the disadvantage that it takes time to start analysis.

Additionally, information such as the instruction that caused the interrupt is generally 16
Since it is displayed in hexadecimal format, it has the disadvantage that only those who are familiar with machine language can analyze it.

In view of the above-mentioned points, an object of the present invention is to enable necessary interrupt information to be obtained through conversation with an interrupt failure analysis mechanism without outputting a list, and to enable even a person without knowledge of machine language to analyze interrupt failures. An object of the present invention is to provide an interactive interrupt information display method that enables the following.

Means for Solving Problem c] The interactive interrupt information display method of the present invention displays the instruction that caused the interrupt saved in the storage device by the operating system when an interrupt failure occurs, the contents of the register at the time of the interrupt, and the interrupt. In the method for analyzing interrupt information including the state of memory at the time of the interrupt, an instruction analysis means for analyzing and editing the instruction that caused the interrupt, and a register analysis means for analyzing and editing the contents of the register at the time of the interrupt. a conversation control means for specifying the start address and length of the memory dump through conversation with a user; and a memory analysis means for analyzing and editing the state of the memory at the time of the interrupt; and the command analysis means; interrupt information input means for inputting the saved interrupt information, which is input information to the register analysis means and the conversational memory analysis means, from the storage device; and conversation information, which is input information to the conversation control means. and a display means for displaying the results edited by the command analysis means, the register analysis means, and the conversational memory analysis means on a display device.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an interrupt failure analysis mechanism for realizing the interactive interrupt information display method of the present invention. Referring to FIG. 1, one embodiment of the present invention includes an interactive memory analysis means 5 consisting of an instruction analysis means 1, a register analysis means 2, a conversation control means 3, and a memory analysis means 4, an interrupt information input means 6, a conversation Information input means 7, display means 8
, interrupt failure analysis mechanism 9, interrupt information save area 10,
It is composed of an input device 11 and a display device 12.

Referring to FIG. 2, the instruction analysis means 1 shown in FIG.
The instruction analysis process in Step 2 of extracting instruction information is
1, a decomposition step 22 into instruction elements, an operand information extraction step 23, an editing step 24 into mnemonic format, and a display step 25 on the display device 12.

Referring to FIG. 3, the register analysis process in the register analysis means 2 shown in FIG.
2, and a display step 33 on the display device 12.

Referring to FIG. 4, the conversational memory analysis process in the conversational memory analysis means 5 shown in FIG. , editing step 43 of the contents of the designated memory into hexadecimal format, and display device 1
2 and a display step 44.

Next, the operation of the conversational interrupt information display system of this embodiment configured as described above will be explained.

When an interrupt occurs, the operating system (hereinafter abbreviated as O8) saves the interrupt information (instruction that caused the interrupt, register contents at the time of the interrupt, memory state at the time of the interrupt, etc.) to the interrupt information save area 10. setting, and the waiting interrupt failure analysis mechanism 9 is activated.

The interrupt failure analysis mechanism 9 first calls the instruction analysis means 1. The instruction analysis means 1 calls the interrupt information input means 6 and retrieves the instruction information @(1 word) of the instruction that caused the interrupt from the interrupt information save area 10 (step 21).
). This instruction information is decomposed into each element of an instruction code, register number, and address formula (step 22). Next, the instruction analysis means 1 calls the interrupt information input means 6 and retrieves operand information of the number of words determined by the address formula from the interrupt information save area 10 (step 23
). Thereafter, the instruction information child operand information is edited into a mnemonic format (step 24), and the display means 8 is called to display it on the display device 12 (step 25).

Next, the interrupt failure analysis mechanism 9 calls the register analysis means 2. The register analysis means 2 calls the interrupt information input means 6 and extracts the contents (40 words) of all registers at the time when the interrupt occurs from the interrupt information save area 10 (step 31). Thereafter, the contents of each register are edited into hexadecimal format (step 32), and the display means 8 is called to display them on the display bag W12 (step 33).

Subsequently, the interrupt failure analysis mechanism 9 calls the conversational memory analysis means 5, which consists of the conversation control means 3 and the memory analysis means 4. The conversation control means 3 calls the conversation information input means 7 and inputs a specification regarding the presence or absence of memory analysis processing to the input device 1.
1, and it is determined whether memory analysis processing is to be performed (step 41).

When the process "none" is specified, the interactive memory analysis process ends. If the process "Yes" is specified, the conversation information input means 7 is further called and the start address and length of the memory dump are input from the input device 11 (step 4).
2). Next, the memory analysis means 4 edits the specified memory contents into hexadecimal format (Step 43), calls the display means 8, and displays them on the display bag 2.12 (Step 4).
4). After this, the operation from the conversation control means 3 is repeated again.

〔Effect of the invention〕

As explained above, by introducing an interactive memory analysis means into the interrupt failure analysis mechanism, the present invention enables necessary memory information to be obtained at the time a failure occurs, and the time required to start analysis is significantly reduced. It has the effect of being shortened.

Furthermore, by introducing an instruction analysis means that displays the instruction that caused an interrupt in mnemonic format, it is possible to analyze an interrupt failure even without knowledge of machine language.
