Description

Computer system having a window message processing means and a method of processing the message {Apparatus and method for control to window message}

The present invention relates to a computer system, and more particularly, to a computer system and a method for processing the window message that improves system performance by controlling the processing of window messages generated during the operation of the computer system.

The basic architecture of modern computers includes peripheral devices that can communicate information with the external environment. These peripheral devices include keyboards, monitors, tape drives, and communication lines that connect to networks. . In addition, the basic structure of the computer is a hardware for receiving and processing information from the outside and transmitting it back to the outside, a plurality of buses, memory units, input / output controllers, storage devices, and a central processing unit (CPU) for controlling the same. ) Are included. The CPU includes a computer program and executes instructions to manage the operation of the components of another system.

On the other hand, most conventional computer systems process window messages that occur in essentially the same way under the control of the CPU. The message processing is a core task of allowing a Windows application program to perform a predetermined task. The computer system and the window application program generate a message for all events occurring in the window. For example, a window generates a message for every hardware event, such as the user pressing a keyboard or clicking a mouse.

In order to process the window message as described above, the conventional computer system 10 stores the window message corresponding to the event when the window event occurs due to the operation of the peripheral device 11 mounted on the computer system. The message queue 12 is provided. In addition, the window message stored among the plurality of threads operated by the computer system 10 to process the window message stored in the message queue 12 affects any one thread. An event check unit 13 for performing a filtering operation for determining whether the message is) is provided. At this time, in the case of the window message that cannot be processed by any thread as a result of the filtering of the event checker 13, the window message is stored and any thread capable of processing the window message is searched. Thereafter, if it is determined that the window message can be processed by any thread during the search, the window message is controlled to be executed.

When the window message is executed by the filtering operation in the event checker 13, an event processor 14 for removing the window message from the message queue 12 is provided. .

However, the prior art as described above has the following problems.

In other words, in recent years, as computer specifications continue to develop, it is required that the speed of computer systems be increased. However, when processing a window message as in the prior art, the computer system performance is inferior because unnecessary filtering is continuously performed on the window message generated by any event.

In addition, there is a problem that the message stored in the message queue is overwritten because the speed of processing the message stored in the message queue does not reach the performance of the system, and thus the message is lost.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to effectively process the window message generated during the operation of the computer system to improve the speed of the system and its window message processing method To provide.

The present invention relates to a computer system and a method for processing the window message thereof, which efficiently process the window message generated during operation of the computer system.

According to a feature of the present invention for achieving the above object, the present invention comprises: a system polling unit for peaking a window message for an event generated by a computer-mounted peripheral device; A message queue in which the window message for each peripheral device is peaked; An event check unit for accessing a window message corresponding to the event among window messages peaked by the message polling unit, when an event occurs; And an event processing unit for executing the window message accessed by the event check unit.

In this case, when the computer system is booted and the OS is driven, the system polling unit sequentially polls a window message corresponding to the event for each peripheral device.

When the window message is executed, the event processor removes the executed window message.

According to another object of the present invention as described above, the present invention comprises the steps of (A) peaking the window message for the event per peripheral device mounted on the computer system; (B) any event during the operation of the computer system Detecting the occurrence of a message and searching for a window message corresponding to the event among the peaked window messages; And (C) executing the searched window message.

In the step (A), when the computer system is booted and the operating system (OS) is started, the window messages of the peripheral devices mounted in the computer system are sequentially polled.

In the step (C), when the window message is executed, the window message is removed.

Meanwhile, step (A), step (B), and step (C) perform independent functions as respective threads.

According to the present invention, when an arbitrary event occurs while the computer is running, the performance of the computer system is improved by searching for and processing a window message for the corresponding event among the window messages that are fitted to the system polling unit. It works.

In addition, the present invention solves the problem that the message is overwritten in the message queue (Que) that occurs because the conventional window message processing speed is less than the performance of the computer system to provide convenience to the user using the computer system It works.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a computer system according to the present invention as described above will be described in detail.

Figure 2 is a block diagram showing the internal configuration of a computer system having a window message processing means according to a specific embodiment of the present invention, Figure 3 is a window message processing method according to a specific embodiment of the present invention The flowchart shown is shown.

As shown in FIG. 2, the computer system 100 of the present invention includes peripheral devices 110 that can communicate information with an external environment. The peripheral device 110 may include a keyboard, a monitor, a tape drive, a communication line connected to a network, and the like. The peripheral devices 110 generate an event through an arbitrary input operation, and the event of the peripheral device 110 generates a message. The message causes the Windows application to perform a predetermined task.

When the computer system 100 is booted and an operating system (OS) is started, a window message for each peripheral device corresponding to an event is sequentially provided to the peripheral device 110 mounted on the computer system. A system polling unit 130 peaks in the background.

And a message queue 120 in which a window message peaked by the system polling unit 130 is stored.

When any event occurs in the peripheral device, an event check for searching for and accessing a window message corresponding to the event among window messages peaked in the system polling unit 130 based on the event The unit 140 is provided.

In addition, an event processor 150 for executing a window message and removing a message stored in the message queue 120 according to the processing result of the event checker 140 is provided.

As described above, the computer system 100 includes a system polling unit 130, the event checker 140, and an event processor 150 to determine whether a conventional window message for each thread can be processed. By reducing the computer system performance is improved.

In addition, the computer system 100 includes a storage unit 160 which stores API functions that are basically executed in driving the computer system 100 and an 'accelerator program' for effectively processing the window message of the present invention. . At this time, the 'accelerator program' is preferably implemented as a multi-threaded program. The multithreaded program is software that allows two or more functions to be executed in parallel within the same application. The 'accelerator program' is configured to perform each function as a separate thread (for example, the system polling unit, the event checking unit, and the event processing unit). The storage unit 160 may be provided with various media, such as an EEPROM, a flash memory, an external memory, and the like, according to the capacity of the stored data.

Hereinafter, a window message processing method of a computer system according to an embodiment of the present invention will be described in detail with reference to FIG. 3.

First, when the computer system 100 is booted, the operating system (OS) operates (S100).

Thereafter, the computer system 100 activates the system polling unit 130 under the control of a central processing unit (CPU). Then, the system polling unit 130 requests a window message corresponding to an event by the peripheral device to all peripheral devices 110 connected to the computer system 100 in sequence, and requests The window message is peaked in the background (S200). The window message causes the Windows application program to perform a predetermined task.

Once peaks have been completed for all peripheral devices, certain events are generated by any peripheral device during the operation of computer system 100. At this time, the event checker 140 detects the event and searches for a window message corresponding to the event among the window messages peaked on the message queue 120 by the system polling unit 130. The window message corresponding to the corresponding event is searched and brought (S400).

Thereafter, when the event checker 140 accesses the peaked window message by the system polling unit 130, the event processor 150 executes the window message and removes the executed window message. (S500).

For example, when a user presses a keyboard or clicks a mouse, the event checker 140 detects a hardware event and the window message peaked by the system polling unit 130. The window message corresponding to the event is obtained and processed. In this case, the processing of the message means that the Windows application program performs a predetermined task.

As described above, when a predetermined event occurs while the computer system is being driven, the confirmation procedure for processing the window message is simplified because the window message peaked by the system polling unit is searched and the window message is processed. The processing speed of a computer system is improved.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and a person skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.
