All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The embodiment of the application provides an expansion slot channel allocation method, an expansion slot channel allocation device, electronic equipment and a storage medium. Before explaining the technical scheme provided by the embodiment of the application, the structure related to the electronic equipment is explained.

As shown in fig. 1, a hardware structure diagram of an electronic device according to an embodiment of the present application is shown.

By way of example, the electronic device may be any electronic product that can interact with a user by one or more of a keyboard, a touchpad, a touch screen, a remote control, a voice interaction, a handwriting device, etc., such as a mobile phone, a notebook computer, a tablet computer, a palm top computer, a personal computer, a wearable device, a smart television, a PAD, etc.

As shown in fig. 1, the electronic device includes: the device comprises a main board 11, a processor 12 arranged on the main board, a plurality of expansion slots 13 arranged on the main board and at least one switch piece 14 arranged on the main board.

By way of example, expansion slot 13 may be a PCIE (PERIPHERAL COMPONENT INTERCONNECT EXPRESS, high speed serial computer expansion bus standard) slot.

Exemplary, the slot types of the plurality of expansion slots arranged on the main board are the same; or, the slot types of the expansion slots arranged on the main board are not identical; or, the slot types of the plurality of expansion slots arranged on the main board are completely different.

Illustratively, the expansion slots of different shapes shown in fig. 1 are different in the type of slot corresponding to the expansion slots of the same shape.

Exemplary slot types include, but are not limited to: any one of a PCIE x1 slot type, a PCIE x4 slot type, a PCIE x8 slot type, a PCIE x16 slot type, and a PCIE x32 slot type.

The expansion slot belonging to the PCIE x1 slot type is the expansion slot PCIE x1; the expansion slot belonging to the PCIE x4 slot type is expansion slot PCIE x4; the expansion slot belonging to the PCIE x8 slot type is expansion slot PCIE x8; the expansion slot belonging to the PCIE x16 slot type is expansion slot PCIE x16; the expansion slot belonging to the PCIE x32 slot type is the expansion slot PCIE x32.

Where xi represents the bandwidth over which i transmission channels can be used in total, i being a positive integer greater than or equal to 1. Illustratively, the maximum bandwidth of the expansion slot PCIEx4 can reach 3.938GB/s, the maximum bandwidth of the expansion slot PCIEx8 can reach 7.877GB/s, and the maximum bandwidth of the expansion slot PCIEx16 can reach 15.754GB/s. And the bandwidths of the transmission channel numbers of PCIEs of different versions have a plurality of different specification standards.

It should be noted that 10 expansion slots are shown in fig. 1, and the embodiment of the present application is not limited to the number of expansion slots provided on the motherboard, for example, the number of expansion slots provided on the motherboard may be any integer greater than or equal to 2, such as 2, 3, 4, …, etc. In fig. 1, 5 switching elements 14 are shown, and the number of switching elements disposed on the motherboard is not limited in the embodiment of the present application, for example, the number of switching elements disposed on the motherboard may be any positive integer such as 1, 2, 3, …, etc.

It should be noted that the positions of the expansion slots, the switching elements, and the processors shown in fig. 1 are only examples and are not limiting.

For example, the plurality of expansion slots may be located on the same side of the motherboard, or on different sides of the motherboard.

It should be noted that the shapes and structures of the expansion slots and the switch members shown in fig. 1 are only examples and are not limited thereto.

It should be noted that, as those skilled in the art will appreciate, the structure of the electronic device shown in fig. 1 is not limited to the electronic device, and more or fewer components than those shown in fig. 1 may be included on a motherboard, or in combination with some components, or in different arrangements of components.

For example, the motherboard 11 may further include a memory slot 15, and the processor 12 may be electrically connected to the memory slot 15 to control the same frequency and the respective operating frequency, and may support functions such as expansion slot data transmission.

In an alternative implementation, the motherboard 11 may also be provided with switching circuitry 16. The switching circuit 16 will be described in connection with the specific implementation, and will not be described in detail here.

It should be noted that the location of the switching circuit 16 on the motherboard 11 shown in fig. 1 is merely an example and is not limiting.

The circuit diagram of the electronic device will be described below with reference to the hardware configuration diagram of the electronic device.

Fig. 2 is a circuit diagram of an electronic device according to an embodiment of the present application.

The processor 12 is connected to a plurality of expansion slots, and in fig. 2, M expansion slots are illustrated as an example, where M is an integer greater than or equal to 2. The M expansion slots are respectively: expansion slot 1, expansion slot 2, expansion slots 3, …, expansion slot M.

The processor 12 allocates a first number of transmission channels for each expansion slot, wherein the first number corresponding to the expansion slot is the number corresponding to the slot type to which the expansion slot belongs; the first numbers of expansion slots belonging to different slot types are different.

For example, if the expansion slot belongs to the PCIE x4 slot type, the processor 12 allocates 4 transmission channels for the expansion slot (i.e., PCIE x4 slot), i.e., the first number is 4; if the expansion slot belongs to the PCIE x8 slot type, the processor 12 allocates 8 transmission channels for the expansion slot (i.e., PCIE x8 slot), i.e., the first number is 8.

Each switch member may be connected to a plurality of expansion slots. Each of the switch elements is illustrated in fig. 2 as being connected to two expansion slots.

For example, for the same switch element, the slot types of the plurality of expansion slots connected with the switch element may be the same, or completely different, or not completely the same.

The number of expansion slots to which different switchgears are connected may be the same or may be different, for example.

And when the switch piece is in the first state, the plurality of expansion slots connected with the switch piece are connected to form a target expansion slot. The processor allocates a second number of transmission channels for the target expansion slot, wherein the second number is the sum of the first numbers corresponding to the connected expansion slots respectively.

For example, assume that 2 switch elements are provided on the motherboard, and the switch elements 1 and 2 are respectively, and that the number of the plurality of expansion slots connected to the motherboard is 3, and the expansion slots PCIEx4, and PCIEx8 are respectively; the switch element 1 is connected to two expansion slots pcie x4, and the switch element 2 is connected to one expansion slot pcie x4 and one expansion slot pcie x8 respectively.

If the user needs to connect two adapter cards corresponding to the expansion slots pcie x8 on the motherboard, for example, a display card and an AI (ARTIFICIAL INTELLIGENCE ) accelerator card, the switch element 1 may be controlled to be in the first state, so that the motherboard includes two expansion slots pcie x8, and the user may insert the display card and the AI accelerator card into the expansion slots pcie x8 respectively.

If the user needs to connect two adapter cards, for example, solid state disks, corresponding to the expansion slots pcie x4 on the motherboard, the switch element 1 may be controlled to be in the second state, so that the motherboard includes two expansion slots pcie x4 and one expansion slot pcie x8, and the two solid state disks are respectively inserted into the expansion slots pcie x4.

If the user needs to connect an adapter card corresponding to the expansion slot pcie x16 on the motherboard, the switch element 1 and the switch element 2 may be controlled to be in the first state, so that the motherboard includes the expansion slot pcie x16, and the adapter card may be inserted.

The following description will be made of "a plurality of expansion slots connected to the switch member in the first state, form a target expansion slot". The present application provides, but is not limited to, the following two cases where "the switch member is in the first state, and a plurality of expansion slots connected to the switch member are connected to form one target expansion slot".

First kind: if the switch pieces are in the first state, and any switch piece of the switch pieces is in the switch pieces, the switch pieces connected with the same expansion slot are all in the switch pieces, and the expansion slots respectively connected with the switch pieces are connected to form a target expansion slot.

It can be understood that if any one of the plurality of switch elements is a switch element having the same expansion slot connected with the switch element, the plurality of expansion slots respectively connected with the switch elements are described as being connected. The following examples are illustrative.

Assume that the number of the plurality of switching elements is 3, and is switching element 1, switching element 2, and switching element 3, respectively; the switch piece 1 is respectively connected with the expansion slot A1 and the expansion slot A2, and the switch piece 2 is respectively connected with the expansion slot B1, the expansion slot B2 and the expansion slot A1; the switch member 3 is connected to the expansion slot B2 and the expansion slot C1, respectively. For the switch piece 1, the same expansion slot A1 is connected with the switch piece 1 by the switch piece 2 in 3 switch pieces; for the switch piece 2, the same expansion slot A1 is connected with the switch piece 2 in the switch pieces 1 in 3 switch pieces; for the switch 3, the same expansion slot B2 is connected to the switch 3 with the switch 2 among the 3 switches. If the switch element 1, the switch element 2 and the switch element 3 are in the first state, the expansion slot A1, the expansion slot A2, the expansion slot B1, the expansion slot B2 and the expansion slot C1 are connected, thereby forming a target expansion slot.

As shown in fig. 3, a schematic diagram of a target expansion slot formed in the case that 3 switch pieces are in a first state according to an embodiment of the present application is shown.

In fig. 3, each switch element is illustrated as being connected to two expansion slots. The number of transmission channels allocated by the processor to the two expansion slots to which each switch is connected is shown in fig. 3. After the 3 switch elements shown in fig. 3 are in the first state, the 4 expansion slots shown in fig. 3 form a target expansion slot, and the number of transmission channels allocated by the processor to the target expansion slot is 32.

Second kind: if one or more of the switch pieces are in the first state and the expansion slots respectively connected with one or more of the switch pieces are different, the expansion slots connected with each switch piece are connected and form a target expansion slot.

The expansion slots to which one or more switch elements are respectively connected are different, so that for each switch element, the expansion slots to which the switch element is connected are connected, and the expansion slots to which different switch elements are connected are not connected, so that the expansion slots to which the same switch element is connected are connected, and a target expansion slot is formed.

In an alternative implementation, in the second state of the switch device connected to the expansion slot, the expansion slot is the original independent expansion slot.

It can be understood that the switch member connected to the expansion slot is in the second state, and the expansion slot is not connected to any expansion slot, so that the expansion slot is an original independent expansion slot, i.e. is itself.

In summary, for a plurality of expansion slots disposed on the motherboard, at least some of the expansion slots form one or more target expansion slots, and/or at least some of the expansion slots are original independent expansion slots. I.e., the electronic device may include one or more target expansion slots, and/or one or more independent expansion slots.

How to control the state of the switch member will be described below. There are various ways of controlling the switch member to be in the corresponding state, and the following two ways are provided in the embodiments of the present application, but are not limited thereto.

First, software control.

The switch member may be controlled by the processor to be in either the first state or the second state.

The switch is a transistor, such as a diode or a triode, and the user can select a target slot type of the expansion slot required by the user through an interface displayed by the electronic device, and the processor determines the target switch from a plurality of switches based on the target slot type to control the target switch to be in the first state.

The target switch piece comprises one or more switch pieces, and the sum of the first numbers corresponding to the expansion slots connected with the target switch piece is the number corresponding to the type of the target slot.

For example, if one or more of the switching elements is in the first state; the processor may determine a target switch piece from the switch pieces in the first state based on the target slot type, and control the target switch piece to be in the second state.

After the control target switch piece is in the second state, the sum of the first numbers corresponding to the expansion slots connected with the switch piece in the first state is the number corresponding to the type of the target slot.

Second, hardware control.

In an alternative implementation, the electronic device further includes a connector.

The switch piece is matched and connected with the connecting piece so as to enable the switch piece to be in a first state; the switch piece is matched and disconnected with the connecting piece so that the switch piece is in a second state.

For example, the switch member is a groove, and the connecting member is a protrusion that mates with the groove.

For example, the switch member may be manually operated to be cooperatively connected with the connecting member, or the switch member may be cooperatively disconnected from the connecting member.

For example, the switch member may be cooperatively connected to the connecting member or may be cooperatively disconnected from the connecting member by software control.

In an alternative implementation, the electronic device further includes a switching circuit 16, where the number of input terminals of the switching circuit 16 is the same as the number of switching elements provided on the motherboard, and one input terminal of the switching circuit 16 is connected to one switching element. The output of the switching circuit 16 is connected to the processor 12.

As shown in fig. 4, a circuit diagram of another implementation manner of the electronic device according to the embodiment of the present application is shown.

The switch is illustratively in a state that is different from the signal detected at the input to which it is connected.

Illustratively, each input of the switching circuit may detect a signal; the signals detected at all inputs of the switching circuit constitute the input signal of the switching circuit.

Illustratively, the switch is in a first state and the signal detected at the input terminal connected to the switch is ON; the switching element is in a second state and the signal detected by the input terminal connected to the switching element is OFF.

The correspondence between the input signal and the output signal is illustrated below.

Assuming that the number of the switch pieces is 2, and the switch pieces are respectively 1 and 2, and assuming that the number of the plurality of expansion slots connected with the motherboard is 3, and the expansion slots are respectively PCIEx4, PCIEx4 and PCIEx8; the switch element 1 is connected to two expansion slots pcie x4, and the switch element 2 is connected to one expansion slot pcie x4 and one expansion slot pcie x8 respectively.

For example, the output signals of the switching circuits corresponding to different input signals are different, and the layout modes of the expansion slots corresponding to different output signals are different. The correspondence between the output signals and the expansion slot layout pattern is preset, and the correspondence between the input signals, the output signals and the expansion slot layout pattern is illustrated in the following, as shown in table 1.

TABLE 1

Illustratively, the number of outputs of the switching circuit is related to the number of output signals, and illustratively, if the number of outputs of the switching circuit is N and the number of output signals is L, 2 ^N is greater than or equal to L. For example, if there are 2 output signals, the number of output terminals of the switching circuit may be 1, and the output signals of the output terminals of the switching circuit may be two signals of a high level signal or a low level signal; if the number of the output signals is 3, the number of the output terminals of the switching circuit may be 2, and the number of the combinations of the signals output by the output terminal 1 and the output terminal 2 may be 4, and the number of the signals is 3.

Illustratively, a low level signal may be represented by 0 and a high level signal may be represented by 1.

Illustratively, the output of the switching circuit may be connected to a pin of the processor, and if the number of output of the switching circuit is 2, illustratively, the output 1 of the switching circuit may be connected to a pin CFG6 of the processor, and the output 2 may be connected to a pin CFG5 of the processor.

It can be understood that if the number of the plurality of expansion slots connected to the motherboard is assumed to be 4, and the expansion slots are respectively the expansion slot pci ex4, the expansion slot pci ex8, and the expansion slot pci ex8; if the target expansion slot is formed as the expansion slot pci ex16, two expansion slots pci ex8 may be formed, or two expansion slots pci ex4 and one expansion slot pci ex8 may be formed. If the target expansion slot is formed by two expansion slots pcie x8, the processor needs to provide 16 transmission channels for the two expansion slots pcie x8; if the target expansion slot is formed by two expansion slots pci ex4 and one expansion slot pci ex8, the processor needs to provide 16 transmission channels for the two expansion slots pci ex4 and one expansion slot pci ex 8. If the target expansion slot is formed by two expansion slots pcie x4 and one expansion slot pcie x8, the processor provides 16 transmission channels for the two expansion slots pcie x8, which is not available 16 transmission channels.

In order to enable the processor to accurately provide a corresponding number of transmission channels for a corresponding expansion slot, the expansion slot layout pattern further includes identification of a plurality of expansion slots forming the target expansion slot, and/or identification of original individual expansion slots.

Illustratively, the identification of the expansion slot characterizes a location of the expansion slot on the motherboard.

The electronic device is described in detail in the embodiments disclosed in the present application, and the method implemented by the electronic device of the present application may be implemented by using various forms of procedures, so the present application also discloses a method, and a specific embodiment is given below for details.

As shown in fig. 5, a flowchart of an expansion slot channel allocation method according to an embodiment of the present application may be applied to a processor of an electronic device, and the method includes the following steps S51 to S53 in an implementation process.

Step S51: a target signal is obtained.

The target signal is an output signal of the switching circuit, for example.

Step S52: and determining a target expansion slot layout mode corresponding to the target signal from the corresponding relation between the preset signal and the expansion slot layout mode.

The target expansion slot layout mode includes: the expansion slot identification set corresponding to the target expansion slot and/or the identification of the independent expansion slot, wherein the expansion slot identification set comprises identifications of a plurality of expansion slots forming the target expansion slot, and each expansion slot layout mode comprises: and forming the identification of the expansion slot of the target expansion slot and/or the identification of the independent expansion slot.

For example, if the switch components respectively connected to the plurality of expansion slots connected to the processor are all in the second state, the plurality of expansion slots connected to the processor are all original independent expansion slots. The corresponding expansion slot layout pattern includes the identification of a plurality of independent expansion slots.

For example, if the switch elements respectively connected to the plurality of expansion slots connected to the processor are all in the first state, the plurality of expansion slots connected to the processor form one or more target expansion slots. The corresponding expansion slot layout pattern includes: and the expansion slot identification sets corresponding to the one or more target expansion slots.

In an exemplary embodiment, if the switch part connected to each of the plurality of expansion slots connected to the processor is in the first state and the switch part is in the second state, a target expansion slot is formed by a part of expansion slots in the plurality of expansion slots connected to the processor, and the part of expansion slots are still original independent expansion slots. The corresponding expansion slot layout pattern includes: and the identification sets of the expansion slots corresponding to the one or more target expansion slots and the identification of the one or more independent expansion slots.

For example, the switch element which is respectively connected with the plurality of expansion slots connected with the processor can be defaulted to be in the second state; the expansion slot layout mode may include only the expansion slot identification set corresponding to the target expansion slot, and the other expansion slots default to independent expansion slots.

Step S53: the second number of transmission channels is allocated in total for expansion slots having identifications of expansion slots forming the target expansion slot based on the target expansion slot layout pattern, and/or the first number of transmission channels is allocated for expansion slots having identifications of independent expansion slots.

In an alternative implementation, the implementation of step S51 is various, and the embodiment of the present application provides, but is not limited to, the following method, which includes steps A1 to A2.

Step A1: an input signal is determined, the input signal comprising a signal detected at an input of the switching circuit.

Step A2: and controlling the switching circuit to output the target signal through the input signal, wherein the target signals corresponding to different input signals are different.

The implementation manner of the switching circuit is various, and the following two kinds of embodiments of the present application are provided but not limited to.

The first implementation mode: and controlling by software.

The correspondence relation between the input signal and the output signal detected by the switching circuit is set in the switching circuit in advance.

The switching circuit is illustratively a controller.

Illustratively, the input signal is the same as the output signal. Illustratively, the input signal is not the same as the output signal.

The second implementation mode: and (5) controlling hardware.

The switching circuit comprises a plurality of switching tubes, and the switching circuit outputs an output signal based on an input signal by controlling the on-off of the switching tubes.

The switching transistor may be a transistor, for example, a diode or a triode, for example.

The following examples illustrate switching circuits, one for each input of the switching circuit, assuming that the input signal of the switching circuit is equal to the output signal. The circuits corresponding to the different input ends are different. For example, a circuit corresponding to one input terminal of the switching circuit may be as shown in fig. 6.

As shown in fig. 6, a circuit diagram of a branch circuit of the switching circuit according to an embodiment of the present application is shown.

The branch circuit includes two transistors, transistor 61 and transistor 62, respectively.

For example, if the switching element connected to the input terminal is in the first state, the signal detected by the input terminal is ON, and if the signal is represented by a high level signal, the transistor 61 is in the ON state, the level at the position 1 is low, so that the transistor 62 is in the off state, and the output terminal outputs the high level signal; if the switching element connected to the input terminal is in the second state, the signal detected by the input terminal is OFF, and if the signal is OFF, the transistor 61 is in the OFF state, and the level at the position 1 is high, so that the transistor 62 is in the on state, and the output terminal outputs the signal of the low level, so that the signal detected by the input terminal is identical to the signal output by the output terminal.

It should be noted that fig. 6 is only an example, and does not limit the switching circuit according to the embodiment of the present application.
