Description

A method for power saving of computer system by using resource monitor analysis}

The present invention relates to a technique for efficiently managing power through a resource monitor analysis of a computer, disabling processes other than the currently running app through a resource monitor analysis of the computer, and in particular, a currently running program needs a security tool When it does not, it relates to a method of saving energy in a computer system through resource monitor analysis to reduce power consumption in a computer system in a simple manner by disabling a security processor that takes a relatively large load.

An operating system (OS) is a part of a computer system that manages all hardware and all software, and manages who can use the system and how.

The operating system can be said to be an intermediate area between hardware and software, controlling hardware, managing computer resources, facilitating computer use, helping applications to perform, and acting as an intermediary between users and hardware.

There is no specific standard model for the organization of the operating system, but overall, most operating system organizations can generally be written in one of three configuration models. That is, it can be classified into i) single component layer, ii) layer component and iii) microkernel component.

Operating system programs are either memory-resident or non-resident, some of the resident programs operate in protected mode, and in many cases called kernel mode, others are traditional user modes.

In the dual, single configuration model, various memory-resident operating system features are presented in a single kernel, with no specific organization. An important function of the kernel operates in protected mode, the rest in user mode. The shell is independent of the kernel and acts as an interface between the user, utilities, and user programs and the kernel. Thus, the shell can be replaced without affecting kernel operation. The main difficulty of a single configuration is the stability and consistency of the entire system, so the program in the kernel can hang the entire system.

On the other hand, the microkernel configuration constitutes a client server system in which the client and server are on the same system. Operating system services other than the basic mode are executed by user mode programs. Each program acts as a server that performs specific operating system tasks at the request of the application model and other operating system programs (clients of this model). The client requests a service by sending a message directly to the microkernel. The microkernel delivers a message to the appropriate server to perform the required function, responds to the request to send the message back to the client, and the response also passes through the microkernel. The security and integrity of the system is maintained because all communication must pass through the microkernel. One of the advantages of microkernel configuration is that while maintaining the security and stability of the microkernel, you can create designs for other operating systems simply by changing service programs outside the microkernel. Macintosh OS X, for example, is one of many operating systems built on the Mach microkernel. The microkernel approach provides reliability, flexibility, scalability, and mobility, but delivering a variety of messages required by the microkernel configuration can degrade performance over other types of designs.

On the other hand, the hierarchical operating system shows that the operating system is divided into several layers, as shown in FIG. 1. The upper layer (user space) 100 is displayed to the user, the middle layer represents the kernel space 200, and the lowermost layer is the I / O device driver 260 that interacts with hardware.

The user space 100 may be represented by the OS 110, the user interface 120, and commands and utilities 130, and the kernel space 200 may include a file service 210 at the top layer and I / at the bottom layer. It consists of the O device driver 260 and the network service 220 of the middle layer, the process manager 230, the resource allocation 240, and the virtual memory manager 250.

For reference, the file service 210 sets and manages a file server capable of storing and sharing files with a user, and the network service 220 is directly connected to a network to store data, operate, present, and communicate functions. Provides, the process manager 230 is similar to the task manager managing the PID (process ID), the resource allocation 240 dynamically allocates and allocates resources to the user.

In this model, each layer is relatively independent of the other layers, so the file manager defines the file location identified by the logical name and interprets the characteristics of the request, but does not attempt to access the hardware directly. Instead, it asks the kernel. After that, the local request is passed to the I / O device driver level to access the hardware. The network request is passed to the I / O device driver of the system providing the service. The layer is arranged such that access to various layers of the operating system originates from the top. Each layer calls the next lower layer. Most computer systems today provide the proper hardware instructions to perform this procedure in the design of the operating system. This is a relatively desirable operating system that provides security as well as an interface between different functions of the operating system.

However, a layered operating system needs to be carefully designed because it is necessary to layer the service so that all requests go down, and a particular layer of programs can compromise the integrity of the system, and intermediate to receive services at the lowest layer. It takes a lot of time to pass the request through the layer.

Accordingly, in the layered operating system (OS) of FIG. 1, in order to increase responsiveness, various resources related to processes, which are not currently used, but currently running programs, and in particular secure processors, are preloaded, and even They also run them directly, regardless of the app they're currently running, which can cause a lot of unnecessary energy to be wasted.

For reference, FIG. 2 is an example of a resource monitor screen for a process, a service connected handle, and a module, FIG. 3 is an example of a resource monitor screen for a process, and FIG. 7 is an example of a job manager screen.

Accordingly, the present inventors, in the layered operating system (OS) of FIG. 1, disable processes other than the currently running app, and a relatively heavy load, especially when the currently running program does not require a security tool. By disabling the processor, it saves power consumption in the computer system, but in particular, it analyzes the resource monitor to manage power efficiently by identifying processes other than the currently running app in a simple manner through the analysis of the resource monitor of the computer.

(Energy saving system of a computer system according to an exemplary embodiment of the present invention)

First, an energy saving system of a computer system through resource monitor analysis according to an exemplary embodiment of the present invention will be described with reference to FIG. 4.

The energy saving system of the computer system through the analysis of the resource monitor according to the best embodiment of the present invention, as shown in FIGS. 1 and 4, the user space 100 as an upper layer includes the OS 110 and the user interface 120 ) And commands and utilities 130, the kernel space 200 as an intermediate layer includes a file service 210 at the top layer, an I / O device driver 260 at the bottom layer, and a network service 220 at the middle layer. ), Process manager 230, resource allocation 240, and virtual memory manager 250.

The energy saving system of the computer system through the analysis of the resource monitor according to the optimal embodiment of the present invention, in addition, the processor manager app 160 and the processor thread save area 170 are required, and the processor manager app ( 160) is connected to the app-related DB 150 and the resource monitoring 140 function.

Thus, the processor manager app 160 checks the currently running app (process) by monitoring the resource monitor as shown in FIGS. 3 and 4 using the resource monitor 140 function, and from the app association DB 150 It calls the program DB associated with the currently running app, and stops apps and processors that are not currently running. For example, this can be done by sorting the processes in the order of the most loads to see if they are truly running according to the number of threads.

The processor thread save area 170 is a temporary storage space used to store the current state information of the currently running app and then call it upon return to return.

Meanwhile, a current processor control unit 270, a display control unit 280, and an I / O device PM control unit 290 are added to the kernel space 200 of the energy saving system of the computer system through the resource monitor analysis according to the present invention. The file manager and the device manager 165 in the processor manager app 160 store current state information of apps or processes that are not currently running in the processor thread save area 170, and then perform a current processor control unit ( 270) while controlling an app or process that is actually executed, processes that are not actually related to the currently executed app or processes are deactivated, and additionally, the display control unit 280 is a file manager and device in the processor manager app 160. Turn off or stop the display device among the hardware through the I / O device driver 260 according to the instruction from the manager 165, and the I / O device PM control unit 290 is a file in the processor manager app 160 The I / O device among hardware is turned off or stopped through the I / O device driver 260 according to instructions from the manager and the device manager 165.

That is, the app-related DB 150 stores information required to execute a specific app, and the processor thread save area 170 has information necessary to return after saving the current state, and includes the file manager and The device manager 165 is required when the processor manager app 160 stops a specific process and then re-executes files and sleeps the device.

(Computer system energy saving method according to an exemplary embodiment of the present invention)

Now, a method for saving energy of a computer system through resource monitor analysis according to an exemplary embodiment of the present invention will be described with reference to FIGS. 5 and 6.

The energy saving method of the computer system through the analysis of the resource monitor according to the best embodiment of the present invention, first, as shown in FIG. 5, the processor manager app 160 uses the resource monitor 140 function in FIG. 3 and As shown in FIG. 4, by monitoring the resource monitor (S1), the currently running app and processor ('A') are identified, and the program DB ('B') associated with the currently running app is checked from the app association DB 150. You will be called (S2).

At this time, in the app-related DB 150, process and application app information that is an execution program, a processor required for system operation, and processor information required for security must be stored.

Subsequently, it is checked whether the execution app and processor ('A') checked in step S2 and the program DB ('B') associated with the current running app called in step S2 match (S3), and step S3. As a result of judging from, if there is a match, the process proceeds to the next step (S5) and sorting is performed in the order of the processor that is heavily loaded. At this time, the degree of heavy load refers to CPU usage, CPU average usage, threads, etc., so it is checked whether it is a true running app according to the number of threads.

On the other hand, as a result of the determination in step S3, when the two do not match, the apps and processors not in the list are set to unused to match the two (S4), and then the process proceeds to step S5.

Continuing, is the program currently being used the most loaded? It is checked whether it is checked (S6), otherwise, it is possible that the virus program is executed. Therefore, the virus check process (steps S7 to S9) is executed. As a result of the determination in step S6, the currently used program is loaded most If it is determined that there are many, the process proceeds to step S11 of FIG. 6.

In the virus check process, is the PID (Process ID) of the system idle process (0) first? It is checked whether or not (S7). As shown in the task manager execution screen of FIG. 7, when most normal programs are executed, the PID of the system idle process is '0', and if the PID of the system idle process is not '0', the virus It is likely that the program is running.

Therefore, when it is determined in step S7 that the PID of the system idle time process is not '0', a virus check program is executed (S8), and then it is checked whether or not a virus is detected (S9). If is found, the process is terminated and the computer system is returned to other generally defined processes such as virus treatment or virus warning and waiting for treatment.If no virus is found in step S9 (as a result of the determination in step S7, the system idle time) If the PID of the process is '0'; and as a result of the determination in step S6, the same is the case when the program being used has the most load) Now, proceeding to step S11 of FIG. 6, is the program being used the Internet? ? Is checked.

As a result of the determination in step S11, if the Internet is not in use, the processor for bank security is disabled (S12), and if the Internet is in use, is it a site that needs a security tool? It is checked whether or not (S13).

Thus, as a result of the determination in step S13, if the Internet site in use is not a site requiring a security tool, after disabling a security processor other than the system general security processor (S14), immediately after the site requiring the security tool, a security tool is required. Is the site closed? It is checked whether or not (S15).

Thus, as a result of the determination in step S15, if a site requiring a security tool has not been terminated, it is continuously checked, and if a site requiring the security tool has been terminated, a security processor other than system security (eg, a pill) is disabled (S16), Is the new app launched now? If it is checked (S17), if a new app is found, the process proceeds to step S2 of FIG. 5 and the steps S2 to S17 are repeatedly performed, and if a new app is not found as a result of the determination in step S17, the system is terminated. As a result, once the computer maintains the idle state for a certain period of time (for example, 3 minutes), the PCI Ex bus and I / O devices are put into sleep mode, and then the entire computer system is shut down.

The idle state in the step S18 may be determined, for example, when there is no key input such as a keyboard or mouse, there is no standby IP of the work manager, and the CPU usage is less than 15%, but is not limited thereto.

According to the energy saving method of the computer system through the resource monitor analysis of the present invention, it is possible to identify the currently running app in a very simple way through the resource monitor analysis, and resources other than the resources associated with it can be disabled because it is unnecessary. You can try to save energy by running the app, and if you don't need a processor for bank security and other security processes that consume a lot of energy, you can disable these processors, furthermore, the risk of virus execution and the possibility of unnecessary energy use. By drastically reducing, it is possible to provide a method for saving energy in a computer system through resource monitor analysis.

In the above, the present invention has been described in accordance with an embodiment of the present invention, but those skilled in the art to which the present invention pertains also include modifications and modifications within the scope of the present invention without departing from the technical spirit of the present invention.
