2 is a block diagram showing an internal configuration of a computer in which the present invention operates.

The present invention relates to data sharing and control between two or more systems, and more particularly, to a system control and sharing device that can receive and use data by controlling a computer, which is a second device, from a PDA, which is a first device.

Hereinafter, the related art and related art will be described.

In general, data can be transmitted / received by communicating between PDA and portable computer.

However, in the related art, data can be transmitted and received only when the PC is turned on through the PDA, files can be viewed or utilized on the PC, and when the notebook is off, the notebook has to be opened and turned on to perform such a task. .

The present invention connects the PDA to the notebook by cable to enable the notebook on / off without opening the notebook, the data file in the notebook through the cable so that you can see through the PDA when moving to transport or open the notebook It is suggested to provide convenience to users by looking at PDA through cable when you want to see simple things without it.

The system control and sharing apparatus of the present invention comprises: a first apparatus incorporating a predetermined key for controlling the second apparatus in data transmission and control between the first apparatus and the second apparatus; And notifying the control signal operation to a keyboard control unit based on a control signal by the operation of the predetermined key, receiving an execution command according to the control operation from the keyboard control unit, and executing the control operation to the power supply unit to execute the control operation. And a second device including a peripheral device control unit for transmitting a command.

According to one embodiment of the present invention, a power-on / off signal using a button or a special key, which is a predetermined key, is transmitted from the PDA as the first device to the PC as the second device, and the signal is received by the peripheral device controller in the PC. Informs the event to turn on / off the power to the keyboard controller, and the keyboard controller sends a signal to turn on / off one or more power types to the south bridge which is a peripheral controller in response to the power on / off event. By sending the signal, the south bridge sends the one or more power on / off signals to power logic to form each type of power in Power Logic.

In addition, as an embodiment of the present invention, the data of the second device is transmitted to the first device so that at least one display and utilization can be performed.

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating controlling power in two devices of the present invention.

As shown in the figure, the PDA 10 as the first device has a button or a predetermined key (not shown) for controlling the connected PC 20 as the second device.

      The second device notifies the control signal operation to the keyboard control unit 22 based on the control signal by the operation of the predetermined key, receives an execution command according to the control operation from the keyboard control unit, and the control operation is performed. A south bridge (ICH4-M or ICH6-M) 21, which is a peripheral device control unit for transmitting the execution command to the power supply unit 23 to be executed, is included.

The operation of the present invention by the above configuration is as follows.

First, each part of this invention is explained further.

     1. PDA stands for Personal Digital Assistants and is a Poprtable device.

      2. Mobile PC; As a Mobile Personal Computer (Notebook), it is relatively bulkier than the PDA.                     

    3. ICH4 or ICH6; The overall system control and input / output control functions according to the internal and external events. It is commonly called South Bridge.

     4. Embedded Controller (Keyboard Controller); The overall system is controlled according to the events occurring inside and outside.

      5. Power Logic; This is the logic that forms the power supplied to the system.

 6. Cable; It is a connection line connecting the PDA and the PC.

       Hereinafter, the operation at power on by the above configuration will be described.

The PDA 10 sends a power-on signal using a button or a special key to the mobile PC 20.

When the signal is received from ICH4 (or ICH6) in the mobile PC, it informs the event to turn on the power to the embedded controller (EC).

When the embedded controller receives such an event, the ICH4 (or ICH6) is used to supply power for the entire system in the same way as the power-on process through the power button on the mobile PC. (3V, 5V, 1,5V, etc.) Send a signal to send a signal that powers on.

When ICH4 (or ICH6) receives the signal from the EC, it transmits On signals of various power sources (3V, 5V, 1.5V, etc.) to the power logic so that each type of power can be formed in the power logic. Power Logic supplies each power system.

        Therefore, even if you do not control the power by opening the Mobile PC directly, you can check the files in the PC through the PDA by turning on the Mobile PC in the same way.

        Power off is also done through a routine similar to On.

        The PDA sends a power-off signal using a button or special key.

        The ICH4 (or ICH6) receiving the signal turns off the power through a process of powering off the mobile PC.

2 is a block diagram showing an internal configuration of a computer in which the present invention operates.

As shown in the figure, a CPU 30 for controlling the system; A first chipset (North bridge) 32 in contact with the CPU processor to perform a system memory bus input / output adjustment function; A second chipset (South bridge) 35 that manages input / output functions of peripheral devices; A BIOS ROM (37) which is a third memory in which a program for recognizing and setting hardware devices in the system, booting the system, booting the system, and finding an operating system or data for emergency recovery of the system after booting the system; Power logic 39, which is a power applying means; Storage means 42 in which an OS or the like is stored; The main memory 33, the video controller 31, the I / O controller 34, the keyboard controller 38, and the like are configured.

As described above, the present invention relates to data sharing and control between two or more systems, and more particularly, to a system control and sharing device that can receive and use data by controlling a computer, which is a second device, from a PDA, which is a first device.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents.                     

It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Therefore, the above description is not limited to the scope of the present invention by the limitation of the claims.

The present invention connects the PDA to the notebook by cable to enable the notebook on / off without opening the notebook, the data file in the notebook through the cable so that you can see through the PDA when moving to transport or open the notebook When you want to see simple things without looking at the PDA through the cable to provide convenience to the user.
