背景技术Background technique
随着科技的进步，电脑的功能趋于多样化，各式各样的周边设备也不断推陈出新。为了能够方便使用者提升电脑效能或是扩充电脑功能，电脑的主机板上一般会配置加速图形端口(AcceleratedGraphicsPort，AGP)、外围组件互联(PeripheralComponentInterconnect，PCI)、快捷PCI(PCIExpress，PCI-E)等总线插槽，以供使用者插入显卡、声卡、网卡等扩充卡。此外，电脑主机上也会配置火线(Firewire)、通用串行总线(UniversalSerialBus，USB)等扩充接口，以供使用者连接硬盘、打印机等外部装置。With the advancement of technology, the functions of computers tend to be diversified, and various peripheral devices are constantly being introduced. In order to facilitate users to improve computer performance or expand computer functions, the motherboard of the computer is generally equipped with accelerated graphics port (Accelerated Graphics Port, AGP), peripheral component interconnect (Peripheral Component Interconnect, PCI), express PCI (PCI Express, PCI-E), etc. The bus slot is used for users to insert expansion cards such as a graphics card, a sound card, and a network card. In addition, expansion interfaces such as Firewire and Universal Serial Bus (USB) are also configured on the host computer for users to connect external devices such as hard disks and printers.
最近，美国英特尔(Intel)公司推出了全新的霹雳(Thunderbolt)接口，其是整合PCI-E和显示端口(DisplayPort)两项技术，而可在同一条缆线中同时传送数据及图像串流。图1是现有霹雳接口的数据传输示意图。请参照图1，霹雳传输技术是在同一条缆线12中提供两个通道122、124作为PCI-E和显示端口，以分别传输数据及图像串流。通过配置在缆线12两端的霹雳控制器14、16的控制，每个通道在两个方向上的传输都可达到每秒10十亿比特(GigaBit，GB)的传输量，使得电脑与周边设备之间可来回高速传输数据。霹雳传输技术提供的带宽还可供多台高速装置以菊花链(Daisy-chain)的方式串接，而无须使用集线器或交换器。Recently, Intel Corporation of the United States has introduced a new Thunderbolt (Thunderbolt) interface, which integrates PCI-E and DisplayPort (DisplayPort) two technologies, and can simultaneously transmit data and image streams in the same cable. FIG. 1 is a schematic diagram of data transmission of an existing Thunderbolt interface. Please refer to FIG. 1 , the Thunderbolt transmission technology provides two channels 122 , 124 in the same cable 12 as PCI-E and DisplayPort to transmit data and image streams respectively. Through the control of the thunderbolt controllers 14 and 16 arranged at the two ends of the cable 12, the transmission of each channel in both directions can reach a transmission volume of 10 billion bits (GigaBit, GB) per second, making the computer and peripheral equipment Data can be transferred back and forth at high speed. The bandwidth provided by Thunderbolt transmission technology can also allow multiple high-speed devices to be connected in daisy-chain (Daisy-chain) without using hubs or switches.
举例来说，图2是现有霹雳接口的菊花链串接架构的示意图。请参照图2，为了实现菊花链的串接方式，作为主控端的主机22需要配置一个霹雳接口端口224及一个支援双通道传输的霹雳控制器222，其后续串接的霹雳接口装置24、26、28则都需要配置两个以上的霹雳接口端口244、246、264、266、284、286。其中，由于每个霹雳接口均具有两个通道，因此这些霹雳接口装置24、26、28内还需要配置一个支援4个通道的霹雳控制器242、262、282，无形之间也增加了装置的生产成本。For example, FIG. 2 is a schematic diagram of the daisy-chain serial architecture of the existing Thunderbolt interface. Please refer to FIG. 2 , in order to realize the daisy chain connection mode, the host computer 22 as the master control terminal needs to be equipped with a Thunderbolt interface port 224 and a Thunderbolt controller 222 supporting dual-channel transmission, and its subsequent series-connected Thunderbolt interface devices 24, 26 , 28 need to configure more than two Thunderbolt interface ports 244, 246, 264, 266, 284, 286. Among them, since each Thunderbolt interface has two channels, these Thunderbolt interface devices 24, 26, 28 also need to be equipped with a Thunderbolt controller 242, 262, 282 supporting 4 channels, which also increases the number of devices. Cost of production.
然而，目前霹雳接口的两个通道仅个别用以传送数据及图像串流，不支援通道集成(channelaggregation)，从而使得传输效能受到限制。当使用者串接的霹雳装置中不包含显示相关装置时，用以传输图像串流的通道将被闲置，连带使得高成本配置的霹雳接口端口及霹雳控制器只能提供一半的传输效能，形成资源浪费。此外，菊花链的串接架构也不允许两个主控(master)装置并存，只能由单一个主控装置与其他串接装置传输数据，相对的也限制了霹雳装置的应用范围。However, currently, the two channels of the Thunderbolt interface are only used to transmit data and image streams individually, and do not support channel aggregation (channel aggregation), thus limiting the transmission performance. When the Thunderbolt device connected in series by the user does not include a display-related device, the channel used to transmit the image stream will be idle, and the high-cost configuration of the Thunderbolt interface port and the Thunderbolt controller can only provide half of the transmission performance, resulting in Waste of resources. In addition, the serial connection structure of the daisy chain does not allow two master devices to coexist, and only a single master device can transmit data with other serial devices, which also limits the application range of the Thunderbolt device.

第一种状态是当第二主控装置98同时使用第一通道及第二通道传输数据，此时第一主控装置96会被设定为绕道模式，而由第三控制器962输出控制信号00至多工器968，而控制多工器968将接点C连接至接点F，以及将接点D连接至接点E；第二主控装置98则会使用通道Q’(即第一通道)来与第一类接口装置92传输数据，以及使用通道P’来与第二类接口装置94传输数据。The first state is when the second main control device 98 uses the first channel and the second channel to transmit data at the same time, at this time the first main control device 96 will be set to bypass mode, and the third controller 962 will output the control signal 00 to the multiplexer 968, and the control multiplexer 968 connects the node C to the node F, and connects the node D to the node E; the second main control device 98 will use the channel Q' (ie, the first channel) to communicate with the first channel A type of interface device 92 transmits data, and uses a channel P' to transmit data with a second type of interface device 94 .
第二种状态是当第一主控装置96使用第一通道传输数据，第二主控装置98使用第二通道传输数据，此时第一主控装置96会由第三控制器962输出控制信号01至多工器968，而控制多工器968将接点A连接至接点C，以及将接点B连接至接点F，使得第一主控装置96可使用第一通道与第一类接口装置92传输数据；第二主控装置98则会使用通道P’(即第二通道)来与第二类接口装置94传输数据。The second state is when the first main control device 96 uses the first channel to transmit data, and the second main control device 98 uses the second channel to transmit data, at this time the first main control device 96 will output a control signal from the third controller 962 01 to the multiplexer 968, and the control multiplexer 968 connects the node A to the node C, and connects the node B to the node F, so that the first master control device 96 can use the first channel to transmit data with the first type interface device 92 The second main control device 98 will use the channel P' (ie, the second channel) to transmit data with the second type interface device 94 .
第三种状态是当第一主控装置96使用第二通道传输数据，第二主控装置98使用第一通道传输数据，此时第一主控装置96会由第三控制器962输出控制信号10至多工器968，而控制多工器968将接点A连接至接点D，以及将接点B连接至接点E，使得第一主控装置96可使用第二通道与第二类接口装置94传输数据；第二主控装置98则会使用通道Q’(即第一通道)来与第一类接口装置92传输数据。The third state is when the first main control device 96 uses the second channel to transmit data, and the second main control device 98 uses the first channel to transmit data, at this time the first main control device 96 will output a control signal from the third controller 962 10 to the multiplexer 968, and the control multiplexer 968 connects the node A to the node D, and connects the node B to the node E, so that the first main control device 96 can use the second channel to transmit data with the second type interface device 94 ; The second main control device 98 will use the channel Q' (ie the first channel) to transmit data with the first type interface device 92 .
综上所述，本发明的菊花链串接装置的数据路由系统及方法是将霹雳接口装置设计为只能使用霹雳接口的其中一个数据传输通道来传输数据，藉此可节省霹雳装置的硬件配置成本。此外，与这些霹雳装置串接的主控装置则会依据使用者、外部装置或另一个串接的主控装置的数据存取需求，分配使用霹雳接口的两个通道或其中一个通道来传输数据，因此可增加霹雳装置的使用弹性以及应用范围。To sum up, the data routing system and method of the daisy chain serial device of the present invention is to design the thunderbolt interface device to only use one of the data transmission channels of the thunderbolt interface to transmit data, thereby saving the hardware configuration of the thunderbolt device cost.
