本發明係關於一種雙顯卡模組之電源控制方法，特別是一種使用同一電源控制模組以針對不同顯卡模組進行供電控制切換之電源控制方法，以及使用該方法之電腦系統。The invention relates to a power control method for a dual graphics module, in particular to a power control method using the same power control module to perform power supply control switching for different graphics modules, and a computer system using the same.
一般可攜式電腦會設置有內建顯卡，以因應電腦之基本顯示需求；而針對注重影音功能之較高階可攜式電腦來說，制式規格之內建顯卡已不敷使用，因此會對應設置較高規格之獨立顯卡，以增加其顯示效能。部分機種為提供顯示效能多樣化之選擇，會同時設置內建顯卡及獨立顯卡，以供電腦系統視使用需求而切換執行。Generally, the portable computer will be equipped with a built-in graphics card to meet the basic display requirements of the computer. For higher-end portable computers that focus on audio and video functions, the built-in graphics card of the standard specification is no longer sufficient, so it will be set accordingly. A higher specification discrete graphics card to increase its display performance. In order to provide a variety of display performance options, some models will also set up a built-in graphics card and a discrete graphics card for the computer system to switch between executions.
新一代的顯示模組，無論是採內建顯卡或是獨立顯卡設計，均針對其執行效能大幅提升，相對地亦增加了其電力需求；對此，各大廠(例如Intel及NVIDIA等)所設計的顯示卡開始支援雙相直流對直流轉換器(two phase DC to DC power converter)，以提供足夠電力。然而，光是電腦的CPU本身就需要一組雙相或三相直流對直流轉換器，若再加上不只一組的新顯示模組，則需要設置多組雙相直流對直流轉換器，如此將與可攜式電腦之輕薄化設計大相逕庭。此外，不同顯示模組所需要之控制電壓及控制方式亦有所差異，例如Intel內建顯卡採用SMBUS做為切換訊號傳輸路徑，而NVIDIA獨立顯卡則採用GPIO訊號，使得在支援雙顯卡之電腦機種上內部電路設置將會更趨複雜。A new generation of display modules, whether built-in graphics cards or discrete graphics design, have significantly improved their performance and relatively increased their power requirements. For this, major manufacturers (such as Intel and NVIDIA) The designed display card began to support two phase DC to DC power converters to provide sufficient power. However, the CPU of the computer itself needs a set of two-phase or three-phase DC-to-DC converters. If more than one set of new display modules is added, multiple sets of dual-phase DC-to-DC converters need to be set. It will be very different from the slim and light design of portable computers. In addition, the control voltages and control methods required by different display modules are also different. For example, Intel built-in graphics cards use SMBUS as the switching signal transmission path, while NVIDIA discrete graphics cards use GPIO signals to enable computer models that support dual graphics cards. The internal circuit settings will be more complicated.

為能讓 貴審查委員能更瞭解本發明之技術內容，特舉出較佳實施例說明如下。In order to enable the reviewing committee to better understand the technical contents of the present invention, the preferred embodiments are described below.
請先參考圖1係本發明之電腦裝置100之示意圖。在本發明之一實施例中，電腦裝置100係為可攜式電腦，例如筆記型電腦、平板電腦、小筆電等，但依據應用類型不同，電腦裝置100亦可為其他設有二個顯示模組以上之裝置，不以本實施例為限。Please refer to FIG. 1 for a schematic diagram of a computer device 100 of the present invention. In an embodiment of the present invention, the computer device 100 is a portable computer, such as a notebook computer, a tablet computer, a small notebook computer, etc., but depending on the type of application, the computer device 100 may have two other displays. The device above the module is not limited to this embodiment.
如圖1所示，本發明之電腦裝置100包括系統模組110、內建顯卡模組120、獨立顯卡模組130及整合電源控制模組140，且整合電源控制模組140係與系統模組110、內建顯卡模組120及獨立顯卡模組130電性連接，使得整合電源控制模組140用以接收系統模組110所發出之切換訊號，並依據切換訊號輸出電壓供內建顯卡模組120及獨立顯卡模組130共用。在本發明之一實施態樣中，系統模組110可為硬體(例如電路、電子晶片等)、軟體(例如儲存於硬碟或記憶體中之作業系統或程式等)、韌體或前述任兩者以上之結合，但本發明並不以此為限。As shown in FIG. 1 , the computer device 100 of the present invention includes a system module 110 , a built-in graphics module 120 , a discrete graphics module 130 , and an integrated power control module 140 , and integrates the power control module 140 and the system module. 110. The built-in graphics module 120 and the independent graphics module 130 are electrically connected, so that the integrated power control module 140 is configured to receive the switching signal sent by the system module 110, and output the voltage according to the switching signal for the built-in graphics module. 120 and the discrete graphics module 130 are shared. In an embodiment of the present invention, the system module 110 can be a hardware (such as a circuit, an electronic chip, etc.), a software (such as an operating system or a program stored in a hard disk or a memory), a firmware, or the foregoing. Any combination of the two or more, but the invention is not limited thereto.
內建顯卡模組120係設定有內建顯卡待機模式及內建顯卡執行模式，係依據所取得之電壓不同而選擇進入不同模式；其中當內建顯卡模組120取得最低電壓值時，則進入內建顯卡待機模式。獨立顯卡模組130設定有獨立顯卡待機模式及獨立顯卡執行模式，亦依據所取得之電壓不同而選擇進入不同模式；其中當獨立顯卡模組130取得最低電壓值時，則進入獨立顯卡待機模式。在本發明之一實施態樣中，內建顯卡模組120為採用Intel GPU之內建顯卡，而獨立顯卡模組130則為採用NVIDIA GPU之獨立顯卡，但本發明不以此為限。The built-in graphics card module 120 is provided with a built-in graphics card standby mode and a built-in graphics card execution mode, and is selected to enter different modes according to the obtained voltage; wherein when the built-in graphics card module 120 obtains the lowest voltage value, it enters Built-in graphics card standby mode. The discrete graphics module 130 is configured with a separate graphics standby mode and a separate graphics execution mode, and is also selected to enter different modes according to the obtained voltage; wherein when the discrete graphics module 130 obtains the lowest voltage value, the discrete graphics standby mode is entered. In one embodiment of the present invention, the built-in graphics module 120 is a built-in graphics card using an Intel GPU, and the discrete graphics module 130 is a discrete graphics card using an NVIDIA GPU, but the invention is not limited thereto.
整合電源控制模組140係以系統管理匯流排(SMBUS)160與系統模組110電性連接，便於進行彼此間之訊號傳輸。整合電源控制模組140包括主電源控制單元141及顯卡模組電源控制單元142，主電源控制單元141用以控制輸出至中央處理單元150之電壓，而顯卡模組電源控制單元142則用以同步控制輸出至內建顯卡模組120及獨立顯卡模組130之電壓，即讓內建顯卡模組120及獨立顯卡模組130同時共用顯示模組電源控制單元142。The integrated power control module 140 is electrically connected to the system module 110 by a system management bus (SMBUS) 160 to facilitate signal transmission between each other. The integrated power control module 140 includes a main power control unit 141 and a graphics card power control unit 142. The main power control unit 141 is configured to control the voltage output to the central processing unit 150, and the video card power control unit 142 is used to synchronize. The voltage output to the built-in graphics module 120 and the discrete graphics module 130 is controlled, that is, the built-in graphics module 120 and the discrete graphics module 130 share the display module power control unit 142 at the same time.
在本實施例中，主電源控制單元141係藉由雙相或三相直流對直流電源轉換器(two or three phase DC to DC power converter)以控制輸出至中央處理單元之電壓，而顯卡模組電源控制單元142則藉由另一組雙相直流對直流電源轉換器以控制輸出至內建顯卡模組120及獨立顯卡模組130之電壓。藉由本發明之設計，即使採用兩組不同之顯卡模組，也只需要多增加一組雙相直流對直流電源轉換器，以減少對應線路及供電元件之設置；且由於內建顯卡模組120與獨立顯卡模組130不需要同時啟動，因此同時間內只會有一個顯卡模組會使用到直流對直流電源轉換器之最大電流，因此僅利用一組雙相直流對直流電源轉換器即可因應本發明之需求。此外整合電源控制模組140更可藉由嵌入式控制器(embedded controller,EC)或/及南橋晶片(platform controller hub,PCH)來同步控制內建顯卡模組120及獨立顯卡模組130，本發明不以此為限。In this embodiment, the main power control unit 141 controls the voltage output to the central processing unit by a two-phase or three-phase DC to DC power converter, and the video card module The power control unit 142 controls the voltages output to the built-in graphics module 120 and the discrete graphics module 130 by another set of dual-phase DC-to-DC power converters. With the design of the present invention, even if two different sets of graphics cards are used, only one set of dual-phase DC-to-DC power converters needs to be added to reduce the setting of the corresponding lines and power supply components; and because the built-in graphics module 120 It does not need to be started simultaneously with the discrete graphics module 130, so only one graphics card module will use the maximum current of the DC-to-DC power converter at the same time, so only one set of dual-phase DC-to-DC power converters can be used. In response to the needs of the present invention. In addition, the integrated power control module 140 can simultaneously control the built-in graphics module 120 and the discrete graphics module 130 by using an embedded controller (EC) or/and a platform controller hub (PCH). The invention is not limited to this.
請參考圖2係本發明之雙顯卡模組之電源控制方法之流程圖。須注意的是，以下雖以圖1所示之電腦裝置100為例說明本發明之雙顯卡模組之電源控制方法，但本發明並不以適用於電腦裝置100為限，任何其他具類似架構之電腦裝置亦可適用本發明之方法。如圖2所示，本發明之雙顯卡模組之電源控制方法包括步驟S201至步驟S206。以下將詳細說明該方法之各個步驟。Please refer to FIG. 2, which is a flowchart of a power control method of the dual graphics module of the present invention. It should be noted that although the computer device 100 shown in FIG. 1 is taken as an example to illustrate the power control method of the dual graphics module of the present invention, the present invention is not limited to the computer device 100, and any other similar architecture. The computer device can also be adapted to the method of the present invention. As shown in FIG. 2, the power control method of the dual graphics module of the present invention includes steps S201 to S206. The various steps of the method are described in detail below.
步驟S201：提供一整合電源控制模組140，用以輸出電壓供內建顯卡模組120及獨立顯卡模組130共用。Step S201: An integrated power control module 140 is provided for outputting voltage for sharing between the built-in graphics module 120 and the discrete graphics module 130.
電腦裝置100係包括整合電源控制模組140，使得內建顯卡模組120及獨立顯卡模組130均透過此整合電源控制模組140之顯卡模組電源控制單元142，來控制輸出至內建顯卡模組120及獨立顯卡模組130之電壓大小，藉以切換目前系統所執行之不同顯卡模組。The computer device 100 includes an integrated power control module 140, so that the built-in graphics module 120 and the discrete graphics module 130 both control the output to the built-in graphics card through the graphics card power control unit 142 of the integrated power control module 140. The voltage of the module 120 and the discrete graphics module 130 is used to switch between different graphics modules executed by the current system.
步驟S202：藉由整合電源控制模組140接收一切換訊號。Step S202: Receive a switching signal by the integrated power control module 140.
電腦裝置100可透過系統模組110產生對不同顯卡模組之切換訊號，而此切換訊號可藉由系統管理匯流排160傳送至整合電源控制模組140予以接收。The computer device 100 can generate a switching signal for different graphics card modules through the system module 110, and the switching signal can be transmitted to the integrated power control module 140 through the system management bus bar 160 for receiving.
步驟S203：依據切換訊號輸出一基本固定電壓，以使得內建顯卡模組120進入內建顯卡待機模式，或使得內建顯卡模組120及獨立顯卡模組130分別進入內建顯卡待機模式及獨立顯卡待機模式。Step S203: output a basic fixed voltage according to the switching signal, so that the built-in graphics card module 120 enters the built-in graphics card standby mode, or causes the built-in graphics card module 120 and the discrete graphics module 130 to enter the built-in graphics card standby mode and independently. Graphics card standby mode.
本發明在進行顯卡模組之切換前，為保持系統之穩定性，整合電源控制模組140必須先提供固定之最小電壓值，用以將執行中之內建顯卡模組120或獨立顯卡模組130先行進入對應之待機模式，以便進行後續之顯卡模組切換操作。In order to maintain the stability of the system before the switching of the graphics card module, the integrated power control module 140 must first provide a fixed minimum voltage value for executing the built-in graphics module 120 or the discrete graphics module. 130 first enters the corresponding standby mode for subsequent video card module switching operations.
在本發明之一實施例中，假設電腦裝置100原本正執行內建顯卡模組120(即處於內建顯卡執行模式)，而獨立顯卡模組130則為斷電狀態。當整合電源控制模組140接收到切換訊號後，首先先輸出基本固定電壓單獨供應給內建顯卡模組120，使得內建顯卡模組120由原先之內建顯卡執行模式進入內建顯卡待機模式，此時基本固定電壓等於供內建顯卡模組120可進入其內建顯卡待機模式之最小電壓值。In an embodiment of the present invention, it is assumed that the computer device 100 is originally executing the built-in graphics card module 120 (ie, in the built-in graphics card execution mode), and the discrete graphics module 130 is in the power-off state. After the integrated power control module 140 receives the switching signal, the basic fixed voltage is first separately supplied to the built-in graphics module 120, so that the built-in graphics module 120 enters the built-in graphics standby mode from the original built-in graphics execution mode. At this time, the basic fixed voltage is equal to the minimum voltage value for the built-in graphics card module 120 to enter the built-in graphics card standby mode.
在本發明之另一實施例中，假設電腦裝置100原本正執行獨立顯卡模組130(即處於獨立顯卡執行模式)，而內建顯卡模組120則處於內建顯卡待機模式。當整合電源控制模組140接收到切換訊號後，先輸出基本固定電壓同時供應給內建顯卡模組120及獨立顯卡模組130，以使內建顯卡模組120繼續保持其內建顯卡待機模式，並使獨立顯卡模組130由原先之獨立顯卡執行模式進入其獨立顯卡待機模式；此時供內建顯卡模組120可進入其內建顯卡待機模式之最小電壓值，加上供獨立顯卡模組130可進入其獨立顯卡待機模式之最小電壓值之和，即為此基本固定電壓。In another embodiment of the present invention, it is assumed that the computer device 100 is originally executing the discrete graphics module 130 (ie, in the discrete graphics execution mode), and the built-in graphics module 120 is in the built-in graphics standby mode. After the integrated power control module 140 receives the switching signal, the basic fixed voltage is output to the built-in graphics module 120 and the discrete graphics module 130, so that the built-in graphics module 120 continues to maintain its built-in graphics standby mode. And the independent graphics card module 130 enters its independent graphics card standby mode from the original independent graphics card execution mode; at this time, the built-in graphics card module 120 can enter the minimum voltage value of the built-in graphics card standby mode, plus for the independent graphics card module Group 130 can enter the sum of the minimum voltage values of its discrete graphics card standby mode, i.e., a substantially fixed voltage for this purpose.
步驟S204：判斷切換訊號對應於內建顯卡模組120或獨立顯卡模組130。Step S204: determining that the switching signal corresponds to the built-in graphics card module 120 or the discrete graphics module 130.
在整合電源控制模組140接收到切換訊號後，接著判斷切換訊號是對應於內建顯卡模組120或獨立顯卡模組130，以便針對不同之顯卡模組採取不同操作或提供不同之電壓值。而針對切換訊號不同，以選擇續行下列步驟S205或步驟S206。After the integrated power control module 140 receives the switching signal, it is determined that the switching signal corresponds to the built-in graphics module 120 or the discrete graphics module 130 to perform different operations or provide different voltage values for different graphics modules. For the difference of the switching signals, the following steps S205 or S206 are continued.
步驟S205：當切換訊號對應內建顯卡模組120時，切斷對獨立顯卡模組130之供電，並輸出第一供電電壓至內建顯卡模組120以進入內建顯卡執行模式。當整合電源控制模組140判斷切換訊號對應內建顯卡模組120時，因無須執行獨立顯卡模組130之相關功能，因此整合電源控制模組140會切斷對獨立顯卡模組130之供電，使其自獨立顯卡待機模式變更為斷電狀態，以節省電量消耗；同時整合電源控制模組140會輸出第一供電電壓至內建顯卡模組120以使其進入內建顯卡執行模式，使得電腦裝置100藉由執行內建顯卡模組120用以顯示畫面。此第一供電電壓係根據系統所執行程式或負載不同而因應變化調整，且由於獨立顯卡模組130不會耗電，因此第一供電電壓係不大於內建顯卡模組120於內建顯卡執行模式下所需要之最大供電電壓。Step S205: When the switching signal corresponds to the built-in graphics card module 120, the power supply to the discrete graphics module 130 is cut off, and the first power supply voltage is outputted to the built-in graphics card module 120 to enter the built-in graphics card execution mode. When the integrated power control module 140 determines that the switching signal corresponds to the built-in graphics module 120, since the related functions of the discrete graphics module 130 are not required to be executed, the integrated power control module 140 cuts off the power supply to the discrete graphics module 130. The self-independent graphics card standby mode is changed to the power-off state to save power consumption; at the same time, the integrated power control module 140 outputs the first power supply voltage to the built-in graphics card module 120 to enter the built-in graphics card execution mode, so that the computer The device 100 is configured to display a picture by executing the built-in graphics card module 120. The first power supply voltage is adjusted according to the program or load executed by the system, and since the discrete graphics module 130 does not consume power, the first power supply voltage is not greater than the built-in graphics card module 120 executing on the built-in graphics card. The maximum supply voltage required in the mode.
步驟S206：當切換訊號對應獨立顯卡模組130時，輸出第二供電電壓至獨立顯卡模組130及內建顯卡模組120，使得獨立顯卡模組130進入獨立顯卡執行模式，且內建顯卡模組120保持對應之待機模式。當整合電源控制模組140判斷切換訊號對應獨立顯卡模組130時，整合電源控制模組140會輸出第二供電電壓至獨立顯卡模組130以使其進入獨立顯卡執行模式，使得電腦裝置100藉由執行獨立顯卡模組130用以顯示畫面；而因為內建顯卡模組120無法完全停止其運作，仍需要提供足夠電壓以將內建顯卡模組120保持在內建顯卡待機模式下，因此第二供電電壓係為供應獨立顯卡模組130及內建顯卡模組120之電壓總和。此第二供電電壓亦會根據系統所執行程式或負載不同而因應變化調整，其中第二供電電壓係不大於獨立顯卡模組130於獨立顯卡執行模式下所需要之最大供電電壓及內建顯卡模組120於內建顯卡待機模式下所需要之最小供電電壓之和。此外，由於第二供電電壓之最大值會大於第一供電電壓之最大值，因此第二供電電壓之最大值亦等於整合電源控制模組140之最大輸出電壓值。Step S206: When the switching signal corresponds to the discrete graphics module 130, output the second power supply voltage to the discrete graphics module 130 and the built-in graphics module 120, so that the discrete graphics module 130 enters the independent graphics execution mode, and the built-in graphics module Group 120 maintains a corresponding standby mode. When the integrated power control module 140 determines that the switching signal corresponds to the discrete graphics module 130, the integrated power control module 140 outputs the second power supply voltage to the discrete graphics module 130 to enter the discrete graphics execution mode, so that the computer device 100 The independent graphics card module 130 is used to display the screen; and because the built-in graphics module 120 cannot completely stop its operation, it still needs to provide sufficient voltage to keep the built-in graphics module 120 in the built-in graphics standby mode, so The two supply voltages are the sum of the voltages of the discrete graphics module 130 and the built-in graphics module 120. The second supply voltage is also adjusted according to the program or load executed by the system, wherein the second supply voltage is not greater than the maximum supply voltage and the built-in graphics card required by the discrete graphics module 130 in the discrete graphics execution mode. The sum of the minimum supply voltages required by the group 120 in the built-in graphics card standby mode. In addition, since the maximum value of the second supply voltage is greater than the maximum value of the first supply voltage, the maximum value of the second supply voltage is equal to the maximum output voltage value of the integrated power control module 140.
藉由本發明之設計，針對不同之內建顯卡模組及獨立顯卡模組，僅藉由同一組電源控制模組即可達到不同顯卡模組間之切換控制，不需要對每一個顯卡模組均設置對應之電源控制模組，以避免過多的元件及線路設置，節省成本及使用空間；此外透過對輸出電壓之調整控制，使得系統在執行不同顯卡模組間之切換時更為穩定。With the design of the present invention, for different built-in graphics modules and discrete graphics modules, switching control between different graphics modules can be achieved only by the same set of power control modules, without requiring any graphics card module Set the corresponding power control module to avoid excessive component and circuit settings, saving cost and space; and by adjusting the output voltage, the system is more stable when switching between different graphics modules.
