Abstract

PURPOSE:To obtain an accurate memory estimate by generating a request instruction for area acquisition while a program is in processing execution, and generating an individual program use area control queue corresponding to the ID number of a program which generates an instruction in response. CONSTITUTION:When the area that a program A uses is measured, its ID number is written in a macro instruction GETMAiN, and the individual use area control queue 8 corresponding to the ID number is set up in an operating system OS2. Then if a macro instruction GETMAiN whose ID number is A is generated while the program A is run, the OS2 acquires an area 5-5 on the basis of it to delete desired information in an unused area control queue 7 through the operation of a queue processing part 9, and also add queue information 6-2 into a used area control queue 6 and queue information 8-1 into the queue 8. Then, the contents of the queue 8 are referred to know the area that the program A uses up to the point of time, thus taking a measurement.

Description

[Detailed description of the invention] Technical field of prison invention The present invention particularly relates to a memory usage measurement processing method.

This relates to a memory usage measurement processing method that makes it possible to measure how much data buffer area is actually used by a program running during system tuning or system debugging, for example, during execution. It is.

■Technical background and problems Conventionally, when a program consisting of
It issues a command such as a macro and requests the operational system (hereinafter abbreviated as O8) to acquire the command. In response, O8 acquires a predetermined amount of space on the data buffer area and notifies the program.

The used area management queue and the unused area management queue are updated through memory management queue processing.

Therefore, the usage status of the data buffer area can be known by referring to the usage area management queue. However, 1. For example, when a new program A is created, it is necessary to know in advance how much space the program A will actually use during processing, and to make a so-called memo or estimate9. Although necessary, the used area management queue is collectively managed for each program and does not satisfy the above desire. For this reason, conventionally, estimates have been made by so-called desk calculations, but it is desirable to actually run program A and understand the amount of area that will actually be used.

(QObject and Structure of the Invention The present invention aims to solve the above-mentioned problems.In other words, it aims to make it possible to easily create a used area management queue corresponding to a program. Therefore, the memory usage measurement processing method of the present invention is configured to issue an area ff1i request command to the operational system to acquire an area in the data buffer area while the program is executing the process. In addition, the operational system acquires a predetermined amount of area in the data buffer area, notifies the program, and manages the used area in the data buffer area using a management queue. In response to the area acquisition request command of the program that issued the command, the operational system is configured to notify the ID ≠ number of the program that issued the command, and the operational system checks the ID number and executes the program. The present invention is characterized in that the individual program used area management queue is not created in correspondence with the ID number, but the contents of the individual program used area management queue can be referred to at a predetermined time or at any time. This will be explained below with reference to the drawings.

Embodiment 0 of the Invention The figure shows a configuration diagram that expresses an embodiment of the present invention so that the processing mode is clear. Reference numeral 1 in the figure indicates a data processing device, which is represented by the contents of the memory; 2 indicates programs O8, 3A, and 3B, such as application programs; 4 indicates a data buffer area; 5-0.5-1・・・・・・・・・・
. . . correspond to the areas referred to in the present invention, and 6 is a used area management queue.

6-0, 6-1, ... are respectively queue information,
7 is an unused area management queue, 7-0. 'i'-1,,・
- Each song has cue information, 8 is an individual program usage area management queue, 8-0.8-1. . . . represents queue information, and 9 represents a queue processing unit.

Traditionally, program 3A and program 3B are data
When attempting to acquire an area on the buffer area 4, a macro command such as GETMAjN shown in 9 is issued and processing is requested to the O82. O82 thereby acquires, for example, an area 5-3 on data buffer area 4, and also deletes the desired information from unused area management queue 7 according to the direction of queue processing unit 9, and also clears the used area. For example, queue information 6-1 is added to the management queue 6 to perform memory management.

In the case of the present invention, this point is actively utilized.1 For example, when trying to measure the area actually used by program A, GETMAiN in program A
The ID number of the program A is written in the macro instruction.

On the other hand, in O82, corresponding to the ID number.

An individual program use area management queue 8 is prepared.

By doing this, 1. As shown in the figure, 2. For example, while program A is running, aETyrh with 1D=h
Assume that an iN macro instruction is issued.

Based on this, O82 acquires, for example, area 5-5, improves the operation of queue processing section 9, deletes desired information from unused area management queue 7, and deletes desired information from used area management queue 6. The queue information 6-2 is added to the queue information 6-2, and the queue information 8-1 is added to the individual program usage area management queue-8.

By performing such control, it is possible to know the area used by program A up to (or at) that point in time by referring to the contents of the individual program used area management queue 8 at a predetermined point in time or at any time. This makes it possible to measure the amount used.

(G) As described in detail, according to the present invention, it is possible to accurately measure how much area each arbitrary program actually uses, and so-called memory estimation is accurate. becomes.
