Field of the Invention This invention relates to an expansion card, and more particularly to an expansion card having a Hyper Transport Interface. [Prior Art] The PCI-X (Peripheral Component Interconnect Extended) interface is a new computer bus technology that can increase the transmission speed of computers and peripheral devices. The operating frequency ranges from 66MHz to 133MHz, while the new-generation PCI_X interface. Then use the 64-bit bus to perform 133MHz, even 266MHz operating frequency 'to achieve the maximum data exchange capacity of mB~, 2GB per second. As peripheral devices (such as ultra-fast Ethernet cards, disk array cards, and serial port controllers) have a higher bandwidth requirement, when planning a rack-mount server (Rack mount server) system Both hope that the operating frequency of the ρα_χ slot can be maintained at 100MHz or above, but the PCI-X slot on the motherboard is often used with other devices on the motherboard to use the same PCI bus, so that PCI-X The operating frequency of the slot does not reach 100MHz or 133MHz. The invention aims to provide an expansion card with a super transmission interface, which can increase the number of PCI-X slots and improve the working frequency and performance. The invention provides an expansion card with a super transmission interface, which is suitable for use. On a motherboard, the motherboard has at least one central processing unit, a PCU slot, and a PCI-Express minus. The expansion card with a super-transport interface, 1313815 97-12-9 mainly includes a plurality of PCI-X extensions. Slot, a PCI-X pass-through interface, a super-pass interface, and a PCI-X bridge. The PCI_X pass-through interface is inserted into the Ρα-χ slot for transmitting multiple sets of power signals to these PCI_ ^ Expansion slot. In addition, the PCI_X bridge has a first channel and a second channel, respectively connected to the PCI-X expansion slots. In addition, the ultra-transmission interface is inserted into the PCI_Express slot and electrically coupled to ^ CI-X bridge for transmitting most input/output signals to the central processing. Each PCI-X expansion slot is connected to the HyperTransport interface through a PCI-X bridge, and the HyperTransport interface is directly connected to the at least Central processing benefits, the power required for each PCI-X expansion slot is to obtain power from the motherboard through the ρα_χ bridge and the ultra-transmission interface. According to a preferred embodiment of the present invention, the above-mentioned super-transmission The wheel interface transmits the input/output signals in a point-to-point connection. ', the present invention uses a pci-x bridge to transmit a high-frequency input 'out signal, allowing the expansion card to support an increased bandwidth.

[Embodiment] FIG. 1 is a circuit block diagram of a super-transport interface f expansion port and a motherboard according to a preferred embodiment of the present invention, which is suitable for use in a server of a high-speed computing dual-processor system. Support peripheral devices with high bandwidth requirements, such as ultra-fast Ethernet cards, disk array cards, and serial ATA controllers. At the same time, as the computing speed of the central processing unit is getting faster, 6 1313815 15008 twf.doc/g The expansion card 100 of the present invention is designed with three sets of PCI_X expansion slots 102, 104, 106, which can effectively support multiple ρα_χ interfaces. Peripheral equipment, and its operating frequency can be maintained at 100MHz or 133MHz. Please refer to Figure 1 'This expansion card with super-transport interface is mainly composed of a number of PCI-X expansion slots 1〇2, 1〇4, 1〇6, a pci-X transmission" face 108, PCI The -X bridge 11 〇 and a super-transmission interface 116 are formed. Among them, 'PCI-X expansion slots 1〇2, 1〇4, 1〇6 can support the working frequency of 64-bit φ element bus, while the current PCI-X specification 2.0 can work at 266MHz, so it can support higher bandwidth. Peripherals that are required, such as ultra-high-speed Ethernet cards, disk array cards, and serial ATA control crying, and so on. In addition, the PCI-X transmission interface 1〇8 can be inserted into the PCI-X slot 206 on the motherboard 2's board, the purpose of which is to transmit the motherboard through the power supply pin of the pCI_x transmission interface 1〇8. The power is supplied to each group Ρα_χ expansion slots 1〇2, 104, 106. In this embodiment, the motherboard can provide 25 watts of power to the peripheral device through each set of PCI-X expansion slots 102, 104, 106 for data transmission and reading. In addition, the PCI-X bridge 110 has, for example, a first channel and a first channel 114, and the first channel 112 can be connected to the PCI-X expansion slots 102, 104 of the two 64-bit bus bars, and its operation The frequency can be maintained at 100MHz. The second channel 114 is separately connected to the PCI-X expansion slot 106 of a 64-bit bus, so that its operating frequency can be maintained at 133 MHz. Although the present embodiment connects the two sets of PCI-X expansion slots 102, 104, 106' by the two channels 112, 114, it is not limited to the implementation of the connection type i j i j o |5^08twf doc/g. In addition, the 'ultra-transmission interface 116 can be inserted into the pci_Express slot 202 of the motherboard, and can be electrically coupled to the ρα_χ bridge ιι〇 for transmitting the majority of the input/output signals to the central processing unit on the motherboard 200. 204·History, HyperTransport Interface 116 is a kind of interconnecting platform that can support the central processor (10) and high-speed and high-performance point-to-point interconnection with peripheral devices, which can meet the needs of new-generation computer and communication platform (4), and no Streaming speeds up to 6.4Gbps' to speed up data transfer performance. The Dragon ρα_χ bridge 110 is directly connected to the central processing unit 2 (10) through the super transmission interface 116. Rather, the conventional PCI II flow platoon shares the same frequency as other devices on the motherboard. Therefore, the PCI-X expansion slot The operating frequencies of 102, 104, and 1〇6 can reach at least 100 MHz or more. It is worth noting that the HyperTransport Interface 116 transmits most of the input/output signals by the pin definition of the PCI-Express slot, such as the input/output signal that can transmit 8X8 ultra-transmission specifications, or the 16x16 super-transmission specification. Input/output signals. Therefore, those skilled in the art can use different slot sizes (χ4, χ8 or χΐ6) to design pci_E ss slots with different pin counts. Referring to Figure 2, there is shown a schematic diagram of an expansion card having an ultra-transmission interface in accordance with a preferred embodiment of the present invention. The circuit board 210 has two sets of pins 212, 214' including a PCI-X interface pin 212 for transmitting a power signal to [push the pin 214 of the ultra-transmission interface of the input/output signal to facilitate the work.
