Detailed Description
For the purpose of promoting a better understanding of the objects, aspects and advantages of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
It is to be noted that technical or scientific terms used herein should have the ordinary meaning as understood by those of ordinary skill in the art to which this disclosure belongs, unless otherwise defined. The use of "first," "second," and similar terms in this disclosure is not intended to indicate any order, quantity, or importance, but rather is used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect.
Fig. 1 shows a schematic block diagram of a verification system. The motherboard may be separately interfaced with one or more daughter boards.
As shown in fig. 1, the authentication system 100 includes a motherboard 110 and a daughter board 120 connected to the motherboard 110. The motherboard 110 includes a power output 111 of the motherboard and a motherboard interface 112, and the daughter board 120 includes a voltage converter 121 and a daughter board interface 122. The voltage converter 121 is connected to the power output terminal 111 of the motherboard, and obtains a voltage from the power output terminal 111 and converts the voltage into a voltage required by the daughter board to supply power to the daughter board. The motherboard interface 112 interfaces with the daughter board 120 via a daughter board interface 122 to enable communication of DATA. For example, the daughter board interface 122 needs to perform data communication based on 1.8v voltage, and the voltage converter 121 converts the acquired voltage into 1.8v to be provided to the daughter board interface 122. In order to match the voltage requirement of the daughter board interface 122, generally, after knowing that the voltage required by the daughter board interface 122 is 1.8v, the user sets the voltage of the motherboard interface 112 to be 1.8v matching the voltage of the daughter board interface 122, so that the voltages of the motherboard interface 112 and the daughter board interface 122 are both 1.8 v. With the increase of the number of the daughter boards, the manual setting mode will increase the workload of setting the motherboard interface by the user, and easily cause errors, resulting in the inability of communication between the motherboard and the daughter boards. How to match the voltage of the motherboard interface with the voltage of the daughter board interface to complete the data communication between the motherboard interface and the daughter board interface in the case of reducing the configuration voltage of the user becomes an urgent technical problem to be solved by the technology.
In view of this, the present disclosure provides a daughter board, a motherboard, and a verification system. Wherein, daughter board for being connected to the motherboard includes: a first interface unit for connecting to a second interface unit of the motherboard; and a voltage conversion unit including a voltage input terminal for connection to a power output terminal of the motherboard, a first output port for connection to the first interface unit, and a second output port for connection to the second interface unit, wherein the power of the motherboard provides a first voltage, the voltage conversion unit converts the first voltage into a second voltage, and applies the second voltage to the first interface unit of the daughter board and the second interface unit of the motherboard via the first output port and the second output port, respectively. And a motherboard associated with the daughter board, comprising: a power output terminal for connecting to the voltage conversion unit of the daughter board; a power supply for supplying a first voltage to the daughter board via the power supply output terminal; and a second interface unit for connecting to the daughter board, wherein the second interface unit includes a power input port for receiving a second voltage from the daughter board, the second voltage being obtained by converting the first voltage by the daughter board.
According to the daughter board, the mother board and the verification system provided by the embodiment of the disclosure, the daughter board directly supplies power to the mother board interface and the daughter board interface at the same time, so that the voltage between the mother board interface and the daughter board interface can be ensured to be the same, and the mother board interface and the daughter board interface can perform data communication based on the same voltage. Therefore, the voltage of the corresponding mother board interface does not need to be manually set for different daughter board interfaces, the burden of voltage configuration of a user is reduced, the problem that manual setting is prone to error is avoided, and data communication between the mother board and the daughter boards is guaranteed.
FIG. 2 shows a schematic diagram of a verification system according to an embodiment of the disclosure. As shown in fig. 2, authentication system 200 includes a motherboard 210 and a daughter board 220, daughter board 220 being associated with motherboard 210 to provide extended functionality to motherboard 210.

Therefore, the voltage applied to the second interface unit 212 of the motherboard 210 is the preset voltage required by the daughter board 220, the accuracy of motherboard voltage configuration is improved, the step of manually configuring the interface voltage of the motherboard by a user is omitted, and the workload of voltage configuration by the user is reduced. Meanwhile, the voltages of the first interface unit 222 and the second interface unit 212 are both from the output voltage of the voltage conversion unit 221, and both can implement data communication based on the same voltage (for example, the voltages of high levels in signals are the same during communication, so that the signals can be accurately identified), thereby improving the accuracy and efficiency of motherboard voltage configuration while ensuring normal data communication.
In some embodiments, the voltage conversion unit 221 may include a dc converter. For example, 5v may be converted to 3.3v, 1.8v, 1.2v, etc.; a wider range of input voltage amplitudes can also be adapted.

For the sub-board 320, the required preset voltage is the second voltage U2, the first voltage conversion unit 321 converts the first voltage U1 into the second voltage U2 and applies the second voltage U2 to the third interface unit 312 of the mother board 310 and the fourth interface unit 322 of the sub-board 320, respectively, and the third interface unit 312 and the fourth interface unit 322 implement DATA communication, such as DATA1 communication, based on the second voltage U2.
For the sub-board 330, the required preset voltage is the third voltage U3, the second voltage converting unit 331 converts the voltage U1 into the third voltage U3 and applies the third voltage U3 to the fifth interface unit 313 of the mother board 310 and the sixth interface unit 332 of the sub-board 330, respectively, and the fifth interface unit 313 and the sixth interface unit 332 implement DATA communication, such as DATA2 communication, based on the third voltage U3. The second voltage U2 may be different from or the same as the third voltage U3.
