Description
本發明是有關於一種周邊設備連接技術，且特別是有關於一種採用閃電介面之連接系統、連接裝置及其連接方法。The invention relates to a peripheral device connection technology, and in particular to a connection system using a lightning interface, a connection device and a connection method thereof.
為使電腦系統上的諸多周邊設備的連接介面能夠統一化以及規格化，許多廠商提出了能適用於多樣周邊設備的資料傳輸介面。英特爾公司所提出的雷霆(Thunderbolt)介面率先提出並與蘋果公司進行產品應用，但是雷霆介面需要採用昂貴的控制晶片及線材。In order to unify and standardize the connection interfaces of many peripheral devices on a computer system, many manufacturers have proposed a data transmission interface that can be applied to various peripheral devices. The Thunderbolt interface proposed by Intel was first proposed and applied to Apple, but the Thunder interface requires expensive control chips and wires.
超微半導體(Advanced Micro Devices,Inc；AMD)公司則提出閃電(lightning bolt)介面。由於採用顯示埠介面的裝置在大部分情形下只會使用到顯示埠介面上四個線道(lane)其中的兩個線道，便可傳輸高畫質(Full DH)解析度規格的顯示信號，因此，閃電介面技術便將顯示埠介面上未使用的另外兩個線道提供做為通用序列匯流排(USB)的信號傳輸之用。雖然這雷霆介面與閃電介面同樣使用小型顯示埠(mini DisplayPort；mDP)插槽，但是閃電介面的控制晶片較便宜、現今USB匯流排的適用範圍較廣，且閃電介面僅需沿用原本的顯示埠傳輸線材即可，不需特別另外採購昂貴的線材。因此，閃電介面在建置時所需的成本將優於雷霆介面。閃電介面也可用於取代以往電腦系統上的視 訊圖形陣列(Video Graphics Array；VGA)介面以及用於乙太網路的雙絞線(也稱為RJ45)介面。Advanced Micro Devices, Inc. (AMD) has proposed a lightning bolt interface. Since the device using the display interface can only use two of the four lanes on the display interface in most cases, the display signal of the high-definition (Full DH) resolution specification can be transmitted. Therefore, the lightning interface technology provides the other two lanes that are not used on the display interface for signal transmission as a universal serial bus (USB). Although the Thunder interface and the lightning interface use the mini display port (mDP) slot, the control chip of the lightning interface is cheaper. The current USB bus bar has a wide range of applications, and the lightning interface only needs to use the original display. The wire can be transported without the need to purchase expensive wires. Therefore, the lightning interface will cost more to build than the Thunder interface. The lightning interface can also be used to replace the view on previous computer systems. Video Graphics Array (VGA) interface and twisted pair (also known as RJ45) interface for Ethernet.
然而，現今許多的周邊設備(例如，投影機、網路插槽)仍然使用VGA、RJ45介面，因此電腦裝置便需藉由轉接設備以將採用閃電介面的mDP插槽轉換成VGA和/或RJ45介面，以與周邊設備互連。在閃電介面的相關規格中，電腦裝置以及轉接設備兩者應具備閃電介面之控制晶片。電腦裝置會提供偵測信號，並接收從轉接設備的控制晶片所回應的相關信息。若轉接設備有回應，電腦裝置會判斷轉接設備採用的是閃電介面，相對地，若轉接設備沒有回應，電腦裝置則會判斷轉接設備採用的是被動式顯示埠介面。因此，當此種轉接設備在沒有配置符合閃電介面之控制晶片的情況下，電腦裝置無法讓轉接設備利用另外兩個線道來進行USB的資料傳輸。However, many of today's peripherals (eg, projectors, network slots) still use VGA, RJ45 interfaces, so the computer device needs to convert the mDP slot with lightning interface to VGA and / or RJ45 interface to interconnect with peripheral devices. In the relevant specifications of the lightning interface, both the computer device and the switching device should have a control chip of the lightning interface. The computer device provides a detection signal and receives relevant information from the control device of the switching device. If the transfer device responds, the computer device will judge that the transfer device uses a lightning interface. In contrast, if the transfer device does not respond, the computer device determines that the transfer device uses a passive display interface. Therefore, when such a switching device is not equipped with a control chip conforming to the lightning interface, the computer device cannot allow the switching device to utilize another two lanes for USB data transmission.

為讓本發明之上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the present invention will be more apparent from the following description.
請參照圖1，圖1是符合閃電介面技術之電腦裝置100以及連接裝置110的示意圖。如圖1所示，符合閃電介面技術之電腦裝置100通常具備提供顯示埠(DisplayPort)協定信號103的顯示埠來源單元102、提供資料協定信號105(例如，通用序列匯流排(USB)3.0或USB 2.0)的資料處理單元104、閃電介面控制器106以及閃電介面插槽108。閃電介面插槽108一般是以小型顯示埠(mini DisplayPort；mDP)插槽作為舉例，其具有四個線道，分別表示為lane0、lanel、lane2以及lane3。本案實施例將線道lane0、lane1 稱為第一組線道，並將線道lane2、lane3稱為第二組線道。傳輸線段109可使用一般的顯示埠電纜即可實現。Please refer to FIG. 1. FIG. 1 is a schematic diagram of a computer device 100 and a connection device 110 in accordance with a lightning interface technology. As shown in FIG. 1, the computer device 100 conforming to the lightning interface technology is generally provided with a display port source unit 102 that provides a display port protocol signal 103, and provides a data protocol signal 105 (for example, a universal serial bus (USB) 3.0 or USB. 2.0) data processing unit 104, lightning interface controller 106, and lightning interface slot 108. The lightning interface slot 108 is generally exemplified by a mini display port (mDP) slot having four lanes, designated as lane0, lanel, lane2, and lane3. The embodiment of this case will line lanes lane0, lane1 Called the first set of lanes, and the lanes lane2, lane3 are called the second set of lanes. The transmission line segment 109 can be implemented using a general display cable.
連接裝置110主要包括閃電介面插槽112、閃電介面控制器114、顯示埠串流單元116以及USB處理單元118。於本實施例中，由於此處所指的連接裝置110可以是用於連接其他周邊設備(例如，顯示埠裝置170、網路設備(網路集線器)180、儲存裝置(快閃記憶體裝置190)...等)的底座(docking)裝置，例如，連接裝置110包括一至多個顯示埠連接器120、USB埠130、乙太網路埠140以及音訊插座埠150。於其他實施例中，連接裝置110也可以設置在顯示埠裝置170、網路設備網路集線器180、或是快閃記憶體裝置1902當中。The connection device 110 mainly includes a lightning interface slot 112, a lightning interface controller 114, a display buffering unit 116, and a USB processing unit 118. In this embodiment, the connection device 110 referred to herein may be used to connect other peripheral devices (for example, the display device 170, the network device (network hub) 180, and the storage device (flash memory device 190). The docking device 110 includes, for example, one or more display port connectors 120, a USB port 130, an Ethernet port 140, and an audio jack 150. In other embodiments, the connection device 110 can also be disposed in the display device 170, the network device network hub 180, or the flash memory device 1902.
由於閃電介面技術結合了顯示埠協定以及USB協定，因此閃電介面技術除了可以與符合閃電介面的裝置進行資料處理以外，也可以單純地連接顯示埠裝置(例如顯示螢幕)以顯示影像。也就是，電腦裝置100的閃電介面控制器106可依照透過閃電介面插槽108的裝置類型來相應地調整所需提供的信號種類。圖2是一般符合閃電介面技術之連接方法的流程圖。請同時參照圖1及圖2，於步驟S210，閃電介面控制器106會藉由閃電介面插槽108來判斷是否透過傳輸線段109連接到相應裝置，例如是顯示埠裝置170(如，顯示螢幕)或是連接裝置110。Because the lightning interface technology combines the display protocol and the USB protocol, the lightning interface technology can be used to display data in addition to the device that conforms to the lightning interface, or simply connect the display device (such as the display screen). That is, the lightning interface controller 106 of the computer device 100 can adjust the type of signal to be provided accordingly in accordance with the type of device that is transmitted through the lightning interface slot 108. 2 is a flow chart of a connection method generally in accordance with the lightning interface technology. Referring to FIG. 1 and FIG. 2 simultaneously, in step S210, the lightning interface controller 106 determines, by the lightning interface slot 108, whether to connect to the corresponding device through the transmission line segment 109, such as the display device 170 (eg, display screen). Or connect the device 110.
當連接到相應裝置時，進入步驟S220，閃電介面控制器106對連接之相應裝置發出偵測信號，並判斷是否接收 到相應的回應信號，藉以判斷連接裝置110是否是符合閃電介面的連接裝置110還是顯示埠裝置170。若***的閃電介面插槽108是顯示埠裝置170的話，由於符合顯示埠協定的顯示埠裝置170不會主動回應閃電介面控制器106，只會被動地接收並撥放顯示埠協定信號103，因此閃電介面控制器106在沒有接收到回應信號時，則進入步驟S230，判斷所連接的相應裝置為顯示埠裝置170。於步驟S240中，閃電介面控制器106便將閃電介面插槽108中的所有線道(lane0~lane3)皆用來傳輸顯示埠協定信號103。When connected to the corresponding device, proceeding to step S220, the lightning interface controller 106 sends a detection signal to the connected device, and determines whether to receive A corresponding response signal is sent to determine whether the connection device 110 is the lightning connection device 110 or the display device 170. If the inserted lightning interface slot 108 is the display device 170, since the display device 170 conforming to the display protocol does not actively respond to the lightning interface controller 106, only the display protocol signal 103 is passively received and played. When the lightning interface controller 106 does not receive the response signal, the process proceeds to step S230, where it is determined that the connected corresponding device is the display device 170. In step S240, the lightning interface controller 106 uses all the lanes (lane0~lane3) in the lightning interface slot 108 to transmit the display protocol signal 103.
另一方面，於步驟S220中，若***的閃電介面插槽108是符合閃電介面的裝置(例如，連接裝置110)的話，則進入步驟S250，由於連接裝置110內部設置有符合閃電介面的閃電介面控制器114，且閃電介面控制器114在接收到偵測信號後會回應符合閃電介面的回應信號，使得電腦裝置100的閃電介面控制器106便會依據此回應信號來選擇閃電介面中的兩種模式：全顯示埠模式或是閃電介面模式，以調整第二組線道的連接情形。全顯示埠模式便跟上述連接至顯示埠裝置170相同，閃電介面控制器106、114會將所有線道(lane0~lane3)提供給顯示埠協定信號使用，此時閃電介面控制器114中的切換控制器115利用多工器(MUX)117以將第二組線道(lane2、lane3)連接至顯示埠串流單元116。On the other hand, in step S220, if the inserted lightning interface slot 108 is a device that meets the lightning interface (for example, the connection device 110), then the process proceeds to step S250, and the lightning interface conforming to the lightning interface is disposed inside the connection device 110. The controller 114, and the lightning interface controller 114 responds to the response signal conforming to the lightning interface after receiving the detection signal, so that the lightning interface controller 106 of the computer device 100 selects two of the lightning interfaces according to the response signal. Mode: Full display mode or lightning interface mode to adjust the connection of the second set of lanes. The full display mode is the same as the above connection to the display device 170. The lightning interface controllers 106, 114 provide all the lanes (lane0~lane3) to the display protocol signal, and the lightning interface controller 114 switches. The controller 115 utilizes a multiplexer (MUX) 117 to connect the second set of lanes (lane2, lane3) to the display buffering unit 116.
閃電介面模式則是閃電介面控制器106將閃電介面插槽108中的第一組線道(lane0、lane1)用來傳輸顯示埠協定 信號103至顯示埠串流單元116，並且，依據連接裝置110的需求，將閃電介面插槽108中的第二組線道(lane2、lane3)連接到顯示埠串流單元116、或是將第二組線道(lane2、lane3)連接到USB處理單元118。此時，閃電介面控制器114中的切換控制器115便會依照所述偵測信號並利用多工器(MUX)117將第二組線道(lane2、lane3)連接至USB處理單元118。The lightning interface mode is that the lightning interface controller 106 uses the first set of lanes (lane0, lane1) in the lightning interface slot 108 to transmit the display protocol. The signal 103 is displayed to the 埠 stream unit 116, and the second set of lanes (lane2, lane3) in the lightning interface slot 108 are connected to the display 埠 stream unit 116 according to the requirements of the connection device 110, or Two sets of lanes (lane2, lane3) are connected to the USB processing unit 118. At this time, the switching controller 115 in the lightning interface controller 114 connects the second group of lanes (lane2, lane3) to the USB processing unit 118 in accordance with the detection signal and using the multiplexer (MUX) 117.
然而，由於上述閃電介面控制器106的判斷流程，使得連接裝置110必需設置閃電介面控制器114才能讓電腦裝置100運作在USB傳輸模式。而且，連接裝置110必需自行透過電源供應器160來提供閃電介面控制器114的電源，其無法透過電腦裝置100的連線而從電腦裝置100獲得電源供應，因而造成不方便。However, due to the determination process of the lightning interface controller 106 described above, the connection device 110 must be provided with the lightning interface controller 114 to enable the computer device 100 to operate in the USB transmission mode. Moreover, the connection device 110 must itself supply the power of the lightning interface controller 114 through the power supply 160, which cannot obtain power supply from the computer device 100 through the connection of the computer device 100, thereby causing inconvenience.
因此，本案實施例的精神在於，希望使本實施例的連接裝置能夠不需要配置閃電介面控制器便可通知電腦裝置100以使其進入一種特殊的USB傳輸模式(也稱為，特定模式)，此種特殊USB傳輸模式除了可以同時傳輸顯示埠協定信號跟資料協定信號以外，電腦裝置100還會透過傳輸線段109提供連接裝置的電源，免除連接裝置的供電問題。此外，由於本案所述的連接裝置並不需要配置閃電介面控制器，因此能降低建置成本，並可簡化連接裝置的設計時效。Therefore, the spirit of the embodiment of the present invention is to enable the connecting device of the embodiment to notify the computer device 100 to enter a special USB transmission mode (also referred to as a specific mode) without configuring a lightning interface controller. In addition to transmitting the display protocol signal and the data protocol signal simultaneously, the special USB transmission mode provides the power of the connection device through the transmission line segment 109, thereby eliminating the power supply problem of the connection device. In addition, since the connection device described in this case does not need to be equipped with a lightning interface controller, the construction cost can be reduced, and the design time of the connection device can be simplified.
圖3為符合本案實施例採用閃電介面之連接系統300的示意圖。連接系統300包括電腦裝置310以及連接裝置320。電腦裝置310包括閃電介面控制單元330以及主要處 理單元340。於部分實施例中，電腦裝置310不需必備主要處理單元340。閃電介面控制單元330例如是符合閃電介面的控制器，例如型號為HD3SS2521的控制晶片。連接裝置320包括特定信號產生單元360以及閃電介面插槽350。閃電介面插槽350具備第一組線道(lann0、lane1)及第二組線道(lane2、lane3)。特別提出的是，連接裝置320沒有設置特別適用於閃電介面的閃電介面控制器。FIG. 3 is a schematic diagram of a connection system 300 employing a lightning interface in accordance with an embodiment of the present invention. The connection system 300 includes a computer device 310 and a connection device 320. The computer device 310 includes a lightning interface control unit 330 and a main place Unit 340. In some embodiments, the computer device 310 does not require the primary processing unit 340. The lightning interface control unit 330 is, for example, a controller that conforms to the lightning interface, such as a control chip of the type HD3SS2521. The connection device 320 includes a specific signal generation unit 360 and a lightning interface slot 350. The lightning interface slot 350 has a first set of lanes (lann0, lane1) and a second set of lanes (lane2, lane3). It is specifically proposed that the connection device 320 is not provided with a lightning interface controller that is particularly suitable for the lightning interface.
基於圖3的方塊結構，當連結裝置320透過閃電介面插槽350***電腦裝置310時，連結裝置320的特定信號產生單元360便會透過閃電介面插槽350取得些許電源，並產生特定信號至電腦裝置310的閃電介面控制單元330。此處所指的特定信號產生單元360並非圖1的閃電介面控制器114或是相關的主動式處理單元，而是只能被動地在連結裝置320透過閃電介面插槽350***電腦裝置310的時候，產生預設於特定信號產生單元360當中的特定信號。也就是說，特定信號產生單元360不會接收偵測信號並且回傳回應信號，而只是單純地將特定信號透過特殊傳送方式提供給電腦裝置310的閃電介面控制單元330。此時，閃電介面控制單元330便會依據特定信號以使閃電介面控制單元330運作於特定的USB傳輸模式之下。Based on the block structure of FIG. 3, when the connecting device 320 is inserted into the computer device 310 through the lightning interface slot 350, the specific signal generating unit 360 of the connecting device 320 obtains some power through the lightning interface slot 350 and generates a specific signal to the computer. Lightning interface control unit 330 of device 310. The specific signal generating unit 360 referred to herein is not the lightning interface controller 114 of FIG. 1 or the associated active processing unit, but can only passively insert the computer device 310 through the lightning interface slot 350 when the connecting device 320 is inserted through the lightning interface slot 350. A specific signal preset in the specific signal generating unit 360 is generated. That is to say, the specific signal generating unit 360 does not receive the detection signal and returns the response signal, but merely provides the specific signal to the lightning interface control unit 330 of the computer device 310 through a special transmission mode. At this time, the lightning interface control unit 330 will operate the lightning interface control unit 330 under a specific USB transmission mode according to a specific signal.
此種特定的USB傳輸模式會讓電腦裝置310透過閃電介面插槽350提供連接裝置320的電源、透過上述第一組線道以傳輸顯示埠協定信號、並且會透過上述第二組線道以傳輸資料協定信號。由於本案實施例所提出之特定的USB傳輸模式為閃電介面基本規格中所無，因此本案實施例會透過下述至少兩種舉例以使閃電介面控制單元330以及連接裝置320能夠在符合閃電介面基本規格外還能額外新增本案實施例所描述的功能。也就是說，本案圖3所述 的閃電介面控制單元330並不等同於圖1的閃電介面控制器106，而是有額外新增功能。The particular USB transmission mode causes the computer device 310 to provide power to the connection device 320 through the lightning interface slot 350, through the first set of lanes to transmit a display protocol signal, and to transmit through the second group of lanes. Data agreement signal. Since the specific USB transmission mode proposed in the embodiment of the present invention is not included in the basic specification of the lightning interface, the embodiment of the present invention can enable the lightning interface control unit 330 and the connection device 320 to meet the basic specifications of the lightning interface through at least two examples described below. In addition, the functions described in the embodiment of the present invention can be additionally added. In other words, as shown in Figure 3 of this case. The lightning interface control unit 330 is not identical to the lightning interface controller 106 of FIG. 1, but has additional new features.
本案實施例所述之閃電介面控制器330的三種操作模式列舉如下表(一)所示。The three modes of operation of the lightning interface controller 330 described in the embodiment of the present invention are shown in the following table (1).
下述提供兩種舉例以作為圖3方塊圖的實現方式，但並不受限於此。第一舉例是，特定信號產生單元360利用閃電介面插槽350中的熱插槽偵測接腳所傳輸的熱插拔偵測(hot plug detection)信號HPD，以作為特定信號。第二舉例則是特定信號產生單元360利用顯示埠資訊中的輔助通道AUXCH(例如，兩個接腳AUX_N、AUX_P)，來傳輸具備特定內容的延伸顯示能力識別資料(Extended display identification data；EDID)，以作為上述之特定信號。Two examples are provided below as an implementation of the block diagram of FIG. 3, but are not limited thereto. In a first example, the specific signal generating unit 360 utilizes the hot plug detection signal HPD transmitted by the hot slot detection pin in the lightning interface slot 350 as a specific signal. In the second example, the specific signal generating unit 360 transmits the extended display identification data (EDID) having the specific content by using the auxiliary channel AUXCH (for example, two pins AUX_N, AUX_P) in the display information. To be the specific signal as described above.
圖4為符合本案實施例之第一舉例說明採用閃電介面之連接系統300的示意圖。第一舉例中的顯示埠串流單元116、USB處理單元118皆與上述實施例相同。電腦裝置410的閃電介面控制單元330與連接裝置320的閃電介面插槽350透過熱插拔接腳以相互連接。也就是，閃電介面插槽350除了四個線道lane0~lane3以外還包括熱插拔接腳。一般而言，此熱插拔接腳是在連接裝置320***電腦裝置310時，連接裝置320會透過熱插拔接腳以立即產生普通的熱插拔偵測信號(例如，信號串流”邏輯1”、”邏輯0”、”邏輯1”)，並將其傳輸到閃電介面控制單元330。4 is a schematic diagram of a first embodiment of a connection system 300 employing a lightning interface in accordance with an embodiment of the present invention. The display buffering unit 116 and the USB processing unit 118 in the first example are the same as the above embodiment. The lightning interface control unit 330 of the computer device 410 and the lightning interface slot 350 of the connection device 320 are connected to each other through a hot plug pin. That is, the lightning interface slot 350 includes hot plug pins in addition to the four lanes lane0~lane3. Generally, the hot plug pin is inserted into the computer device 310 when the connecting device 320 is inserted, and the connecting device 320 can automatically generate a hot plug detection signal (for example, signal stream) logic through the hot plug pin. 1", "logic 0", "logic 1") and transmitted to the lightning interface control unit 330.
藉此，本實施例的連接裝置320之特定信號產生單元360是連接至熱插拔接腳的熱插拔偵測(hot plug detection；HPD)信號產生器460。熱插拔偵測信號產生器460在連接裝置320***電腦裝置310時，得以產生一組特殊的熱插拔偵測信號HPD(例如，信號串流”邏輯1”、”邏輯0”、”邏輯1”、”邏輯0”、”邏輯1”)以作為上述之特定 信號。此特定的熱插拔偵測信號HPD符合原有的熱插拔信號格式(也就是，符合”邏輯1”、”邏輯0”、”邏輯1”的信號串流)且額外增加判斷信號(也就是，信號串流最末端額外增加的”邏輯0”、”邏輯1”)。閃電介面控制單元330便可透過熱插拔接腳以接收特定的熱插拔偵測信號HPD_1，使閃電介面控制單元330可判斷此特定的熱插拔偵測信號HPD之產生而進入上述的特定模式。Thereby, the specific signal generating unit 360 of the connecting device 320 of the embodiment is a hot plug detection (HPD) signal generator 460 connected to the hot plug pin. The hot plug detection signal generator 460 generates a special hot plug detection signal HPD (eg, signal stream logic 1", "logic 0", "logic" when the connection device 320 is inserted into the computer device 310. 1", "logic 0", "logic 1") as the above specific signal. The specific hot plug detection signal HPD conforms to the original hot plug signal format (that is, the signal stream conforming to "logic 1", "logic 0", "logic 1") and additionally adds a judgment signal (also That is, "logic 0" and "logic 1" are added at the end of the signal stream. The lightning interface control unit 330 can receive the specific hot plug detection signal HPD_1 through the hot plug pin, so that the lightning interface control unit 330 can determine the specific hot plug detection signal HPD to enter the specific mode.
圖4之電腦裝置310的主要處理單元340可以是中央處理單元(CPU)342和/或平台控制集線器(platform controller hub；PCH)344。於部分實施例中，特定的熱插拔偵測信號可以由CPU 342透過閃電介面控制單元330所傳送的熱插拔偵測信號HPD_2來偵測，從而控制閃電介面控制單元330進入特定模式。此外，CPU 342跟PCH 344可分別提供顯示埠協定信號103以及資料協定信號105到閃電介面控制單元330。The primary processing unit 340 of the computer device 310 of FIG. 4 may be a central processing unit (CPU) 342 and/or a platform controller hub (PCH) 344. In some embodiments, the specific hot plug detection signal can be detected by the CPU 342 through the hot plug detection signal HPD_2 transmitted by the lightning interface control unit 330, thereby controlling the lightning interface control unit 330 to enter a specific mode. In addition, CPU 342 and PCH 344 can provide display protocol signal 103 and data protocol signal 105 to lightning interface control unit 330, respectively.
圖4的連接裝置320更包括顯示埠串流單元116以及通用序列匯流排(USB)處理單元118。顯示埠串流單元116透過第一組線道(lane0~lane1)以接收並處理顯示埠協定信號103。USB處理單元118透過第二組線道(lane2~lane3)以接收並處理符合USB協定的資料協定信號105。USB處理單元118可符合USB 3.0或是USB 2.0規格。The connection device 320 of FIG. 4 further includes a display serial stream unit 116 and a universal serial bus (USB) processing unit 118. The display buffering unit 116 transmits and processes the display protocol signal 103 through the first group of lanes (lane0~lane1). The USB processing unit 118 transmits and processes the data protocol signal 105 conforming to the USB protocol through the second set of lanes (lane2~lane3). The USB processing unit 118 can conform to USB 3.0 or USB 2.0 specifications.
圖5為符合本案實施例之第二舉例說明採用閃電介面之連接系統300的示意圖。第二舉例與上述實施例相似，其不同處在於，特定信號產生單元360利用顯示埠資訊中 的輔助通道AUXCH(例如，兩個接腳AUX_N、AUX_P)，來傳輸具備特定內容的延伸顯示能力識別資料(Extended display identification data；EDID)。由於主要處理單元340通常會對顯示螢幕提取EDID以作為顯示影像的校正依據，因此本案實施例的特定信號產生單元360是連接至輔助通道AUXCH的延伸顯示識別資料(EDID)產生器560，其會產生特定格式的EDID以作為上述特定信號。電腦裝置310的主要處理單元340與連接裝置320的閃電介面插槽350透過輔助通道AUXCH相連。換句話說，閃電介面插槽350還包括輔助通道接腳，此輔助通道接腳用以傳輸EDID。因此，當連結裝置320透過閃電介面插槽350***電腦裝置310時，延伸顯示識別資料產生器560產生特定的EDID以作為特定信號。主要處理單元340透過輔助通道AUXCH以接收並分析此特定的EDID，以控制閃電介面控制器330運作於特定模式。FIG. 5 is a schematic diagram of a second embodiment illustrating a connection system 300 employing a lightning interface in accordance with an embodiment of the present invention. The second example is similar to the above embodiment except that the specific signal generating unit 360 utilizes the display information. The auxiliary channel AUXCH (for example, two pins AUX_N, AUX_P) transmits an extended display identification data (EDID) having a specific content. Since the main processing unit 340 generally extracts the EDID from the display screen as a basis for correcting the display image, the specific signal generating unit 360 of the embodiment of the present invention is an extended display identification data (EDID) generator 560 connected to the auxiliary channel AUXCH, which will A specific format of EDID is generated as the specific signal described above. The main processing unit 340 of the computer device 310 is connected to the lightning interface slot 350 of the connection device 320 through the auxiliary channel AUXCH. In other words, the lightning interface slot 350 also includes an auxiliary channel pin for transmitting the EDID. Therefore, when the linking device 320 is inserted into the computer device 310 through the lightning interface slot 350, the extended display identification data generator 560 generates a specific EDID as a specific signal. The primary processing unit 340 transmits and analyzes this particular EDID through the secondary channel AUXCH to control the lightning interface controller 330 to operate in a particular mode.
圖5的連接裝置更包括顯示埠串流單元116、顯示埠連接器120、USB連接單元118以及周邊連接器(如，USB埠130、乙太網路埠140)。顯示埠串流單元116透過第一組線道及顯示埠連接器120以將顯示埠協定信號103傳送至符合顯示埠協定的顯示埠裝置170。USB處理單元118透過第二組線道及周邊連接器以將資料協定信號105傳送至對應的周邊裝置(如，快閃記憶體裝置190)。The connecting device of FIG. 5 further includes a display port stream unit 116, a display port connector 120, a USB connection unit 118, and peripheral connectors (eg, USB port 130, Ethernet port 140). The display buffering unit 116 transmits the display protocol signal 103 to the display device 170 conforming to the display protocol through the first group of channels and the display port connector 120. The USB processing unit 118 transmits the data protocol signal 105 to a corresponding peripheral device (e.g., flash memory device 190) through the second set of lanes and peripheral connectors.
本案實施例可統整為一種採用閃電介面之連接方法，圖6為符合本案實施例採用閃電介面之連接方法的流程 圖。此連接方法適用於具有例如圖3之電腦裝置310以及連接裝置320的連接系統300，且連接裝置320包括閃電介面插槽350。於步驟S610中，電腦裝置310中的閃電介面控制單元330判斷連結裝置320是否透過閃電介面插槽350***電腦裝置310。當步驟S610為是時，連接裝置320中的特定信號產生單元360產生特定信號至電腦裝置310，其中，連接裝置320並沒有設置符合閃電介面的控制器。於步驟S630中，閃電介面控制單元330對連接之相應裝置發出偵測信號，並判斷是否接收回應信號、特定信號或是沒有回應。若沒有回應，則從步驟S630進入步驟S640，閃電介面控制單元330判斷所連接的裝置是顯示埠裝置，並操作於全顯示埠模式，以將所有線道(lane0~lane3)皆用來傳輸顯示埠協定信號。The embodiment of the present invention can be integrated into a connection method using a lightning interface, and FIG. 6 is a flow corresponding to the connection method using the lightning interface in the embodiment of the present invention. Figure. This connection method is applicable to the connection system 300 having, for example, the computer device 310 of FIG. 3 and the connection device 320, and the connection device 320 includes a lightning interface slot 350. In step S610, the lightning interface control unit 330 in the computer device 310 determines whether the linking device 320 is inserted into the computer device 310 through the lightning interface slot 350. When the step S610 is YES, the specific signal generating unit 360 in the connecting device 320 generates a specific signal to the computer device 310, wherein the connecting device 320 is not provided with a controller conforming to the lightning interface. In step S630, the lightning interface control unit 330 sends a detection signal to the connected device, and determines whether to receive the response signal, the specific signal, or no response. If there is no response, proceed from step S630 to step S640, the lightning interface control unit 330 determines that the connected device is the display device, and operates in the full display mode to use all the lanes (lane0~lane3) for transmission display.埠 Agreement signal.
若於步驟S630接收回應信號，則進入步驟S650，閃電介面控制單元330則操作於閃電介面模式，依據連接裝置的需求以調整第二組線道(lane2~lane3)的連接情形。若於步驟S630接收上述之特定信號(例如，特定的熱插拔偵測信號HPD或是特定的EDID)，則進入步驟S660，電腦裝置310的閃電介面控制單元330依據特定信號以使其運作於特定模式。此特定模式使電腦裝置310透過閃電介面插槽350提供連接裝置320的電源，透過第一組線道以傳輸顯示埠協定信號，並透過第二組線道以傳輸資料協定信號。If the response signal is received in step S630, the process proceeds to step S650, and the lightning interface control unit 330 operates in the lightning interface mode to adjust the connection situation of the second group of lanes (lane2~lane3) according to the requirements of the connection device. If the specific signal (for example, the specific hot plug detection signal HPD or the specific EDID) is received in step S630, the process proceeds to step S660, and the lightning interface control unit 330 of the computer device 310 operates according to the specific signal. Specific mode. This particular mode causes the computer device 310 to provide power to the connection device 320 through the lightning interface slot 350, through the first set of lanes to transmit the display protocol signals, and through the second group of lanes to transmit the data protocol signals.
綜上所述，本發明實施例所述之連接裝置不必裝設符合閃電介面的控制器，而是裝設一個特定信號產生單元，其可以在連接裝置***電腦裝置時產生特定信號。電腦裝置中的閃電介面控制單元會依據此特定信號而運作在特定模式下，使得電腦裝置將會提供連接裝置的電源並進行相應的運作。藉此，連接裝置不需設置符合閃電介面的控制器，便可透過閃電介面來同時存取顯示埠協定信號以及通用序列匯流排信號，因此可降低此種連接裝置的建置成本，並且可簡化連接裝置的設計時效。In summary, the connecting device according to the embodiment of the present invention does not need to be equipped with a controller that conforms to the lightning interface, but a specific signal generating unit that can generate a specific signal when the connecting device is inserted into the computer device. The lightning interface control unit in the computer device operates in a specific mode according to the specific signal, so that the computer device will provide power to the connected device and perform corresponding operations. Therefore, the connection device can simultaneously access the display protocol signal and the universal sequence bus signal through the lightning interface without setting a controller conforming to the lightning interface, thereby reducing the construction cost of the connection device and simplifying The design time of the connecting device.
