Abstract

PURPOSE:To effectively use a resource and to avoid extreme slow processing speed due to slow down, by performing the detection and release of slow down at each resource through the management of types of resources. CONSTITUTION:A resource number is determined and managed at each type of resource and the detection and release of slow down is made at each resource. For example, when a program is started, a required slow down mode SDMF is selected with a central processor CPU1, a request block RB is linked to a start possible matrix RAQ of a memory M2 when the SDME is turned off, a resource stored in a control block CB of a memory 1 is acquired for processing. When the SDMF is turned on at the program start, the request block RB is linked to a processing queve WQ. When the processing of the program is finished, the resource S acquired at the start is returned to the control block CB to turn off the slow down mode SDMF.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control method for managing resources such as memory areas used by each program during program execution.

Generally, when a task such as an application program is started, it is necessary for the program to execute.
It is necessary to acquire resources such as memory areas from the resource management section. If the resource management department unconditionally lends resources one after another to such G@t MaclIK, eventually there will be no more usable resources and the entire Ruu system will become abnormal! If a program is using or is scheduled to use other resources that are not in short supply, it may not start (or it may slow down). Sleeping causes nine disorders.

Therefore, the present invention manages each type of resource, detects and clarifies each type of resource, and utilizes the resource effectively. The purpose of the present invention is to provide a control method that prevents the speed of drifting from becoming extremely slow.

The present invention uses a control method for managing resources such as the beak area used by each programm while the program is running, and separates the axillary resources into two types, and assigns a resource number and resource number corresponding to the programmable type. , and the current number of available resources.

Electricity ν indicating the limit number when lending of gorge resources is prohibited.
Nine total error blocks are provided for each type of wrinkle resource, and information on when the scissors/gastric error occurs can be activated by linking the request block of the program that can be started among the two request blocks. a resource management table having a queue and a resource number and a corresponding four-down mode book and processing queue;
An unactivated boogram request block is connected to the request queue, and it is determined whether there are available resources at 1112 or not.

If the resource resource required for the program's overtime is off, the corresponding request block is linked to the startable matrix and turned on. In this case, link to the corresponding processing queue 11, link to ##I moveable queue, and start the request booter program to acquire resources. Reduce the current value number of ν, and when the current number becomes small, turn on the corresponding Sushidakun mode 7yg, and when the executed boogram returns the resource, the nuclear control F roll boot screen The current number of request blocks is increased, and when the current number becomes too large, the corresponding slowdown lag is turned off, and the request block management queue linked to the processing queue is linked to the overtime available queue. It is characterized by

An embodiment of the present invention will be described below in detail with reference to the drawings.The ninth diagram to explain this embodiment is a napkin diagram showing the CPU, 1 is the CPU, Ml, M21M3 are the main parts So, fuck that!

In the @memory M1 that has an activation matrix and a resource management table, CB is a co/) role error, and the resource number-4SNO indicating the type of resource, the current number of usable resources GK, and lending is prohibited. If this occurs, the vine counter LC, which indicates the limit number of turtle resources, will be biased. Each block CB has its own resource S.

In the message M2, @movable matrix RAQ 嬬 links the request block RB of the startable program. In the resource management table BCT
Company, Sudha corresponding to each resource number 8NO? It has a large processing queue WQ linking the y4-door 2g8DMF and the request program III F/RB of the boot program which cannot be activated.

Next, the operation of this embodiment will be described in detail below. First, when a certain boo program is activated, the slowdown instruction-door flag SDMF of the resource number required for that program is checked. Then, if that IIDMP is off, that boogram cannot acquire resources, so its request boot disk RBF
The i activatable matrix RAQK'Jv is created.

The startable matrix RAQK 9 has been created and the * request block RB program is 8:I from the pre-purchased one to next *
y to fight - y pu IFF/CIIK is held and 1 capital aS is acquired and put into action. decrease. And that G
If GK≧LC by comparing K and LC, C1 lends 8 resources. However, if GK<LC, the line is not lent, and the corresponding down mode flag g in the resource management table BCT is
Turn on the DMF and link the request ``F/RB'' to the processing queue WQK.

In other words, turning on the DMF is equivalent to detecting a slowdown for that resource and notifying it.

On the other hand, if a certain program is activated and the program 80MF is on, the request program t'F/RB is linked to the processing queue WQ.

Next, when the run of 10 Gutsumu is completed, the resource S obtained at the time of startup is returned to the control four-tsuku CB.
- If it is a reset LC, the through-down mode 7 j /BDMF was in the on state before that, so the SDMF is turned off and the processing queue W
The first RB linked to Q is activated matrix RAQ
K'Jink/GK (If it's LC, just return it and there's nothing else to do.

At that time, in the case of GK) I, C, the normal resource 8t can be obtained, but if GK < LC, 4#), this is the case, and in the case where a boot program with a high priority is activated and 9, etc., GK is available. (This is because resources are lent out despite LC.

In this way, switching the 80MF from on to off is equivalent to canceling the slowdown using that resource.

As explained above, according to the present invention, since the resource aS server request server RB is managed for each resource, the resources can be used effectively. Only the program that is trying to obtain 9 resources is slowed down and is not in a wait state, and the program that uses other resources is not subject to any influence, so the processing speed is slow. It won't be extremely slow.

[Claims] In a control method for managing resources such as memory areas used by each program while the program is running, the resources are grouped by type, and the resource number corresponding to the type and the current number of usable resources are determined. 1101 When armpit funds@0 lending is prohibited
A search loop is provided for each mosquito resource type 4I with an electric indicator indicating the number of mosquitoes in the world. Request page with information at the time of startup of carpet fee Gutum Wy/(
) of which an activatable matrix is provided that links the activatable estops, and a resource management table is provided which has the resource numbers and their corresponding resource numbers and processing queues. , Unable to start in the processing queue*! The program's request block is connected to 11, and it is indicated whether there are any resources left available (by turning off the armpits and stomach), which is necessary when the program starts. The slowdown of resources
If the flag is off, the corresponding request block is linked to the activation queue; if it is on, it is linked to the corresponding processing queue, and the module of the request block linked to the mosquito activation queue is activated. When a resource is acquired, the current number of required resources in the control panel is decreased, and when the current number is less than the reit counter, the corresponding slowdown mode flag is turned on, and ! When the executed program returns a resource, it increments the current number of the control block, turns off the corresponding slowdown mode flag when the current number is equal to the current counter, and returns the resource to the process queue.
