Description
본 발명은 컴퓨터시스템에 관한 것으로서, 보다 상세하게는 S3절전모드를 지원하는 컴퓨터시스템에 관한 것이다.The present invention relates to a computer system, and more particularly to a computer system that supports the S3 power saving mode.
컴퓨터의 사용으로 인해 소비전력을 많아지면서, 컴퓨터시스템의 전원소비를감소시키기 위한 방법으로, 일정시간 동안 입력장치로부터 데이터의 입력이 없는 경우에는 디스플레이장치의 디스플레이동작을 정지시키고, 일정 시간동안 하드디스크의 드라이브의 엑세스가 발생하지 않는 경우 하드디스크의 드라이브 동작을 정지시키는 것 등을 통해 컴퓨터의 시스템의 전원소비를 최소화하는 전원관리기능이 컴퓨터에 적용되어왔다.As a method of reducing power consumption of a computer system while increasing power consumption due to the use of a computer, if there is no data input from an input device for a predetermined time, the display operation of the display device is stopped, and the hard disk for a predetermined time. The power management function has been applied to the computer to minimize the power consumption of the computer system by stopping the drive of the hard disk when the drive of the drive does not occur.
최근에는 컴퓨터시스템의 상태를 다섯 가지(S0~S4)모드로 구분하여 시스템의 전원을 관리하는 ACPI(Advanced Configuration and Power Interface Specification)라는 전원관리기능이 제안되어 사용되고 있다.Recently, a power management function called ACPI (Advanced Configuration and Power Interface Specification), which manages the power of the system by classifying the state of the computer system into five (S0 to S4) modes, has been proposed and used.
여기서, ACPI의 S3 모드는 컴퓨터 시스템의 빠른 재사용을 위한 것으로, 이 모드에서는 휘발성 메모리(volatile memory)로 구성되는 시스템 메모리(RAM)와 전원 관리 컨트롤러를 제외한 그 밖의 다른 컴퓨터 하드웨어 장치들로의 전원 공급은 중지된다. 시스템이 S3 모드로 진입하는 과정을 '서스팬드 투 램(suspend to RAM)' 이라고 하며, 상기 과정에서 시스템 메모리에 현재 상태가 저장된다.Here, ACPI's S3 mode is for fast reuse of computer systems, in which power is supplied to other computer hardware devices other than the power management controller and system memory (RAM), which consists of volatile memory. Is stopped. The process of entering the system into S3 mode is called 'suspend to RAM', and the current state is stored in the system memory.
시스템에서 S3 모드로 지정되면 ACPI 기능에 따라 시스템 메모리(RAM)에 현재 작업 상태를 저장하고, 모든 전원이 오프 되게 된다. 그리고, 컴퓨터 시스템이 S3 모드에서 정규 모드로 전환되는 웨이크 업(Wake-Up) 동작에서 일반적인 부팅 과정이 진행되지 않고, 시스템 메모리에 저장되어 있던 내용을 호출하여 빠르게 시스템을 재사용 하게 된다. 따라서, 사용자는 절전효과가 크며, 빠른 시스템의 재사용이 가능한 ACPI의 S3 모드를 지원하는 컴퓨터 시스템을 선호하게 된다.When the system is set to S3 mode, the ACPI function saves the current working state in system memory (RAM) and turns off all power. In the wake-up operation in which the computer system switches from the S3 mode to the normal mode, the general booting process is not performed, and the system system is quickly reused by calling contents stored in the system memory. Therefore, the user prefers a computer system that supports ACPI's S3 mode, which has a large power saving effect and enables fast system reuse.
그런데, 종래의 컴퓨터시스템은, S3모드에서 디스플레이장치에 공급되는 비디오데이터 및 전원을 차단하므로, 디스플레이화면이 블랙상태가 되어, 컴퓨터시스템이 오프된 상태와 구분할 수가 없다. 이에 따라, 사용자는 S3모드상태를 시스템이 오프된 것으로 혼동하여 컴퓨터를 재부팅하면 작업한 데이터를 손실하게 되는 문제가 발생할 수 있다.However, the conventional computer system cuts off the video data and the power supplied to the display device in the S3 mode, so that the display screen is black and cannot be distinguished from the off state of the computer system. Accordingly, the user may confuse the S3 mode state that the system is off, and may cause a problem that the work data is lost when the computer is rebooted.
따라서, 본 발명의 목적은, 디스플레이장치에 마련된 상태표시부에 의해 시스템의 절전상태를 용이하게 인식할 수 있는 컴퓨터시스템을 제공하는 것이다.Accordingly, an object of the present invention is to provide a computer system that can easily recognize the power saving state of the system by the status display unit provided in the display device.

이하에서는 첨부도면을 참조하여 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 컴퓨터시스템의 구성도이다. 도면에 도시된 바와 같이, 전면에 전원스위치(1)가 마련된 컴퓨터본체(10)와, 컴퓨터본체(10)에 연결된 입력장치인 키보드(5) 및 마우스(7)와, 컴퓨터본체(10)의 비디오카드(17)와 비디오커넥터(30)를 통해 연결되며 비디오커넥터(30)를 통해 인가되는 영상신호를 처리하여 화상으로 표시하는 디스플레이장치(20)로 구성된다. 디스플레이장치(20)의 전면 좌측 하단에는 본 발명에 따라 컴퓨터본체(10)의 S3모드상태를 표시하는 표시부(25)로서 LED가 마련된다.1 is a block diagram of a computer system according to the present invention. As shown in the figure, a computer main body 10 provided with a power switch 1 on the front, a keyboard 5 and a mouse 7 which are input devices connected to the computer main body 10, and the computer main body 10 The display device 20 is connected to the video card 17 and the video connector 30 and processes the video signal applied through the video connector 30 to display an image. In the lower left front of the display apparatus 20, an LED is provided as the display unit 25 displaying the S3 mode state of the computer main body 10 according to the present invention.
본 발명에 따라 비디오커넥터(30)에는 R/G/B신호입력핀과 동기신호입력핀이외에도 S3절전상태신호를 인가하기 위한 입력핀이 설정된다(도 4참조).According to the present invention, the video connector 30 is provided with an input pin for applying an S3 sleep state signal in addition to the R / G / B signal input pin and the synchronous signal input pin (see Fig. 4).
도 2는 도 1의 컴퓨터시스템의 내부제어블록도이다. 도면에 도시된 바와 같이, 컴퓨터본체(10)내부에 마련되는 메인보드(미도시)상에는 각종 제어 및 연산기능을 하는 중앙처리장치(11)와, 중앙처리장치(11)와 다른 주변장치를 제어하며, 절전모드로 전환시 주변 장치로의 전원공급이 차단되도록 전원공급부(19)를 제어하는 전원관리콘트롤러의 기능을 하는 칩셋과, 전원관리콘트롤러로의 제어신호와 전원공급부(SMPS: System Management Power Supply)(19)의 절전상태신호를 논리곱하여 반전시키는 낸드게이트(18)로 구성된다.2 is an internal control block diagram of the computer system of FIG. As shown in the figure, the main processor (not shown) provided inside the computer main body 10 controls the central processing unit 11 that performs various control and calculation functions, and the central processing unit 11 and other peripheral devices. And a chipset that functions as a power management controller that controls the power supply unit 19 so that the power supply to the peripheral device is cut off when the power saving mode is switched to, and a control signal and a power supply unit to the power management controller (SMPS: System Management Power). And a NAND gate 18 for inverting and inverting the power saving state signal of the supply 19.
칩셋은 중앙처리장치(11)와 비디오카드(17)간의 제어기능을 하는 노스브리지(13)와, 각종 입출력을 관리하며 중앙처리장치(11)로부터 제공되는 전원명령어에 따라 전원공급부(19)를 제어하기 위한 전원관리기능을 하는 사우스브리지(15)로 구성된다.The chipset controls the north bridge 13, which controls the central processing unit 11 and the video card 17, and the power supply unit 19 according to a power command provided from the central processing unit 11 to manage various inputs and outputs. It is composed of a south bridge (15) that serves as a power management function for controlling.
한편, 디스플레이장치(20)는, S3모드상태표시부(25)와, 비디오커넥터(30)의소정 핀을 통해 입력되는 S3절전상태신호를 감지하며 S3절전상태의 하이/로우상태에 기초하여 S3모드상태표시부(25)의 턴온/턴오프되도록 제어하는 마이컴(23)을 포함한다. 마이컴(23)은 S3절전상태신호가 하이인 경우 S3모드상태표시부(25)를 턴온시키고, S3절전상태신호가 로우인 경우 S3모드상태표시부(25)를 턴오프시킨다.On the other hand, the display device 20 detects the S3 sleep state signal input through the S3 mode state display unit 25 and the predetermined pin of the video connector 30, and based on the high / low state of the S3 sleep state, the S3 mode. It includes a microcomputer 23 for controlling to turn on / off of the status display unit 25. The microcomputer 23 turns on the S3 mode state display unit 25 when the S3 power saving state signal is high, and turns off the S3 mode state display unit 25 when the S3 power saving state signal is low.
여기서, 정상전원이 공급되는 정상모드인 경우 사우스브리지(15)는 S3절전제어신호를 하이레벨로 출력하고, S3절전모드로 전환되면 S3절전제어신호를 로우레벨로 출력한다.Here, in the normal mode in which the normal power is supplied, the south bridge 15 outputs the S3 power saving control signal to the high level, and when the S3 power saving mode is switched, the south bridge 15 outputs the S3 power saving control signal to the low level.
전원공급부(19)는 전원스위치(1)가 온되면, 메인보드에 마련된 전원스위치(1)의 상태감지회로(미도시)에서 출력되는 PS-ON신호를 수령하여 메인보드에 부착된 각 장치에 전원을 공급한 후 정상전원이 공급된다는 표시로서 정상전원상태신호(Power_Good)를 하이레벨로 출력하고, 절전모드로 전환시에는 로우레벨을 출력한다.When the power switch 1 is turned on, the power supply unit 19 receives a PS-ON signal output from a state sensing circuit (not shown) of the power switch 1 provided on the main board and supplies the PS-ON signal to each device attached to the main board. After the power is supplied, the normal power state signal (Power_Good) is output to the high level as an indication that the normal power is supplied, and the low level is output when the power is switched to the power saving mode.
중앙처리장치(11)는 키보드(5) 및 마우스(7)로부터 일정 시간 입력신호가 없는 경우 S3절전모드로 전환하여 S3절전명령어를 출력하고, S3절전명령어는 노스브리지(13)를 통해 사우스브리지(15)로 전달된다. S3절전명령어에 따라 사우스브리지(13)는 전원공급부(19)에 절전제어신호(Sleep_S3)를 로우레벨로 전환하여 전원공급부(19)로 출력한다. 이에 대해 전원공급부(19)는 정상전원상태신호(Power_Good)신호를 로우레벨로 전환하여 사우스브리지(15)측으로 출력한다.When there is no input signal from the keyboard 5 and the mouse 7, the CPU 11 switches to the S3 power saving mode and outputs the S3 power saving command, and the S3 power saving command is connected to the south bridge through the north bridge 13. Is passed to (15). According to the S3 power saving command, the south bridge 13 switches the power saving control signal Sleep_S3 to the low level to the power supply 19 and outputs it to the power supply 19. On the other hand, the power supply unit 19 converts the normal power state signal Power_Good signal to a low level and outputs the signal to the south bridge 15.
본 발명에 따라, 사우스브리지(15)와 전원공급부(19)의 두 출력신호는 낸드게이트(19)의 입력단으로 입력되고, 낸드게이트(19)의 출력값인 S3모드상태신호는 비디오커넥터(30)에 설정된 S3상태신호입력핀을 통해 디스플레이장치(20)로 제공된다.According to the present invention, the two output signals of the south bridge 15 and the power supply unit 19 are input to the input terminal of the NAND gate 19, and the S3 mode state signal, which is the output value of the NAND gate 19, is the video connector 30. It is provided to the display device 20 through the S3 state signal input pin set to.
따라서, 시스템이 정상모드인 경우에는 낸드게이트(19)의 출력은 로우레벨이 되고, 시스템이 S3절전모드인 경우에는 낸드게이트(19)의 출력은 하이레벨이 된다.Therefore, when the system is in the normal mode, the output of the NAND gate 19 becomes low level, and when the system is in the S3 sleep mode, the output of the NAND gate 19 becomes high level.
정상모드와 S3절전모드에 따른 사우스브리지와(15)와 전원공급부(19) 및 낸드게이트(19)의 출력신호를 정리하면 다음과 같다.The output signals of the south bridge 15 and the power supply unit 19 and the NAND gate 19 according to the normal mode and the S3 power saving mode are summarized as follows.
도 3은 도 1의 컴퓨터본체의 전원모드와 S3모드상태표시부의 관계도이다. 도면에 도시된 바와 같이, 컴퓨터본체(10)의 비디오카드(17)와 디스플레이장치(20)가 연결되어 있는 상태에서 S3모드상태표시부(25)가 턴오프이면, 시스템의 전원상태가 정상모드임을 나타내고, S3모드상태표시부(25)가 턴온이면, 시스템의 전원상태가 S3절전모드임을 나타낸다.3 is a relationship diagram of a power mode and an S3 mode state display unit of the computer main body of FIG. As shown in the figure, when the S3 mode status display unit 25 is turned off while the video card 17 and the display device 20 of the computer main body 10 are connected, the power state of the system is in the normal mode. When the S3 mode state display unit 25 is turned on, the power supply state of the system is in the S3 power saving mode.
전술한 실시 예에서는, 절전상태표시부가 LED인 것으로 서술하였으나, beeper를 이용하거나, 다양한 표시장치를 적용할 수 있다.In the above-described embodiment, the power saving state display unit is described as an LED, but a beeper may be used or various display devices may be applied.
이러한 구성에 의하여, 컴퓨터본체의 시스템에서 발생하는 S3절전신호를 비디오커넥터를 통해 디스플레이장치에 입력하고, 입력된 신호의 상태에 따라 표시부를 온오프시킴으로써, 사용자는 용이하게 S3절전모드상태를 파악할 수 있다.With this configuration, the user can easily grasp the S3 sleep mode state by inputting the S3 power saving signal generated by the computer system into the display device through the video connector and turning the display on and off according to the state of the input signal. have.
이상 설명한 바와 같이, 본 발명에 따르면, 디스플레이장치에 마련된 상태표시부에 의해 시스템의 절전상태를 용이하게 인식할 수 있다.As described above, according to the present invention, the power saving state of the system can be easily recognized by the state display unit provided in the display device.
