On the substrate, there are; =; main chip group, bus bar and bus bar slot. Central processing ς TM, day 曰 and through the wafer _ connection bus. The busbars can be routed and programmed into slots. The bus slot can be configured with:: another / ', the element can pass through the bus slot" Jl Hunt 4 control single 7L can carry out network signal and bus (4) == and the control unit can pass through the bus Receive; age is used as a reference clock for work. In the embodiment of the present invention, the bus bar may be a peripheral "PCI" M stream or a peripheral interconnect high speed interface bus. 9 In addition, the expansion card slot on the expansion card can include at least one of the peripheral interconnect: slot, peripheral interconnect high-speed interface slot, and peripheral interconnect wide-band interface slot. 8. Because the expansion card provided by this creation can be configured not only with expansion card slots with different transmissions, but also with a network route interface and control unit. = This, this creation can achieve more work on the effective board area. Since the control unit uses the clock signal in the bus as the working clock, this creation does not need to be on the hardware circuit. Make a big change. The above and other objects, features and advantages of the present invention will become more apparent. 7 M338525 is easy to understand, and the preferred embodiments are described below in conjunction with the drawings and are described in detail below. [Embodiment] FIG. 2 is a system block diagram of a motherboard circuit of a computer system in accordance with a preferred embodiment of the present invention. Referring to FIG. 2, the motherboard circuit 200 provided in this embodiment can be applied to a computer system such as a server having a substrate 202. In some embodiments, substrate 202 can be a printed circuit board (PCB). On the substrate 202, a central processing cry 204, a wafer set 206, a bus bar 208, and a bus bar slot 210 can be disposed. The central processor 204 is connected to the chip set 206, and the chip set 206 can be transferred to the bus bar 208. In addition, the chip set 206 can be coupled to the bus bar slot 210 through the bus bar 208. In the present embodiment, the wafer set 206 can include a north bridge wafer 212 and a south bridge wafer 214. The north bridge chip 212 can be coupled to the central processor 204 and can be coupled to the memory 216. The south bridge wafer 214 can be connected to the north bridge wafer 212 and can be connected to the bus bar 208. The bus 208 is, for example, a peripheral interconnect interface bus or a peripheral interconnect high speed interface bus. In addition, an expansion card 222 can be inserted in the bus bar slot 21A. Thereby, the expansion card 222 can exchange the bus bar signal with the bus bar 208 through the bus bar slot 210. 3A is a circuit block diagram of an expansion card in accordance with a preferred embodiment of the present invention, and FIG. 3B is a top view of the expansion card of FIG. 3A. Referring to FIG. 3A and FIG. 3β together, the expansion card • M338525 300 provided in this embodiment can be applied to the expansion card 222 in FIG. 2, which includes a medium 302, a control unit 304, and a network route interface 3〇6. The control unit 3 (10) is implemented using a single wafer, such as a helper wafer, which can interface with the interface 302 and the network routing interface 3〇6. When the expansion card 3 is inserted in, for example, the bus bar slot 210 of FIG. 2, the expansion card 3 can transmit a bus signal through the interface unit and the bus bar 208. The network route interface 306 can be implemented using the RJ 45, which allows the network route to be plugged in. When the #Scale line is plugged into the network route interface _, the expansion card can receive or network signals through the network route interface 3〇6. When the expansion card 300 S passes the network route interface 3〇6 to receive the network; the control unit 304 can convert it into a bus bar signal and send it to the bus distribution via the = face unit 302. Conversely, when the computer system wants to transmit the network signal, the bus signal can be sent to the expansion card 300 through the bus. At this time, the control unit 3〇4 can convert the bus line signal into a network signal and transmit it out from the network route interface. In general, the sink/guest row, the number can be a digit number, and the network signal can be an analog signal. A special trick is used. When the control unit 3〇4 is in operation, a clock signal can be extracted from the busbar 2〇8 through the interface unit 2〇2 as a working reference clock. Thereby, the control unit 3〇4 can operate normally. In some embodiments, the expansion card 3 can also be configured with an expansion slot, such as 306. The expansion slot 3〇6 can face the interface unit 3〇2 and allow an interface card having the same transmission interface to be inserted thereon. The expansion card slot 306 can include one of a peripheral interconnect interface slot, a peripheral interconnect high speed interface slot, and a peripheral interconnect wide interface interface slot. 9 • M338525 Although the expansion card 300 in FIGS. 3A and 3B is only configured to expand the slot 306, those of ordinary skill in the art will appreciate that multiple expansion slots can be configured simultaneously on the expansion card 3, such as 1A or map, paying the user's actual needs. ^ In summary, the network route interface can be configured on the network card provided by this creation. Therefore, the empty interface of the network card can be omitted on the domain board, and the area of the board is further reduced. In addition, since this creation uses a single-chip to convert the network signal and the bus signal, this creation and the original circuit are too modified, so that the expansion card can be more, although the creation has been better implemented. The example reveals the above, but it is not P艮=this creation' Anyone who is familiar with this art, in the creation and crimes of Lai County, when there are some changes and refinements, the scope of this creation should be attached to the patent application scope. The definition is final. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1A and Figure 1 are continued from a top view of a conventional expansion card.
