For example, the slot types corresponding to the expansion slots of different shapes shown in fig. 1 are different, and the slot types corresponding to the expansion slots of the same shape are the same.
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.
Wherein, the expansion slot belonging to the PCIE x1 slot type is an expansion slot PCIE x 1; an expansion slot belonging to the PCIE x4 slot type is an expansion slot PCIE x 4; an expansion slot belonging to the PCIE x8 slot type is an expansion slot PCIE x 8; an expansion slot belonging to the PCIE x16 slot type is an expansion slot PCIE x 16; an expansion slot belonging to the PCIE x32 slot type is expansion slot PCIE x 32.
Where xi represents the bandwidth where i transmission channels can be used in total, and i is a positive integer greater than or equal to 1. Illustratively, the maximum bandwidth of the expansion slot pcie 4 may reach 3.938GB/s, the maximum bandwidth of the expansion slot pcie 8 may reach 7.877GB/s, and the maximum bandwidth of the expansion slot pcie 16 may reach 15.754 GB/s. And the bandwidth of each transmission channel number of the PCIE with different versions has various different specification standards.
It should be noted that 10 expansion slots are shown in fig. 1, and the number of expansion slots provided on the motherboard is not limited in the embodiments of the present application, 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, …, and the like. Fig. 1 shows 5 switch elements 14, and the number of the switch elements disposed on the main board is not limited in the embodiments of the present application, for example, the number of the switch elements disposed on the main board may be any positive integer such as 1, 2, 3, …, and the like.
It should be noted that the locations of the expansion slots, the switch pieces, and the processor shown in fig. 1 are merely examples and are not limiting.
For example, multiple 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 shape and structure of the expansion slot and the switch member 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 does not constitute a limitation of the electronic device, and the main board may include more or less components than those shown in fig. 1, or may combine some components, or may arrange different 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 for controlling the same frequency and the respective operating frequency, and for supporting functions such as slot data transmission.
In an alternative implementation, the main board 11 may also be provided with a switching circuit 16. The switching circuit 16 is described later with reference to specific implementation manners, which are not described herein again.
It should be noted that the position of the switching circuit 16 on the main board 11 shown in fig. 1 is merely an example and does not cause limitation.
The following describes a circuit diagram of an electronic device with reference to a 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 M expansion slots are illustrated in fig. 2 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 slot 3, …, and expansion slot M.
The processor 12 allocates a first number of transmission channels to each expansion slot, where the first number corresponding to the expansion slot is a number corresponding to a slot type to which the expansion slot belongs; the first number of expansion slots belonging to different slot types is different.
For example, if the expansion slot belongs to the PCIE x4 slot type, the processor 12 allocates 4 transmission channels to the expansion slot (i.e., PCIE x4 slot), that is, the first number is 4; if the expansion slot is of the PCIE x8 slot type, the processor 12 allocates 8 transmission channels to the expansion slot (i.e., PCIE x8 slot), that is, the first number is 8.
Each switch member may be associated with a plurality of expansion slots. Fig. 2 illustrates an example in which each switch is connected to two expansion slots.
For example, the slot types of the expansion slots connected to the same switch member may be the same, or completely different, or not completely the same for the same switch member.
For example, the number of expansion slots connected by different switch pieces may be the same or different.
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. And the processor allocates a second number of transmission channels to the target expansion slot, wherein the second number is the sum of the first numbers respectively corresponding to the plurality of connected expansion slots.
In the electronic device provided by the embodiment of the application, a plurality of expansion slots connected with a processor are arranged on a mainboard, at least one switch piece is arranged on the mainboard, and each switch piece is respectively connected with the plurality of expansion slots; when the switch piece is in a first state, a plurality of expansion slots connected with the switch piece are connected to form a target expansion slot; therefore, the user can control the state of the switch piece based on the type of the adapter card to be inserted, so that a target expansion slot matched with the type of the adapter card to be inserted is formed, and the expansion capability of the mainboard is improved.
For example, assume that 2 switches are disposed on the motherboard, and are respectively switch 1 and switch 2, and assume that the number of the expansion slots connected to the motherboard is 3, and are respectively an expansion slot pci express 4, an expansion slot pci express 4, and an expansion slot pci express 8; the switch 1 is connected to two expansion slots pcie 4, and the switch 2 is connected to one expansion slot pcie 4 and one expansion slot pcie 8, respectively.
If a user needs to connect two adapter cards corresponding to the extension slot pcie 8, for example, a display card and an AI (Artificial Intelligence) accelerator card, to the motherboard, the switch 1 may be controlled to be in the first state, so that the motherboard includes two extension slots pcie 8, and the user may insert the display card and the AI accelerator card into the extension slot pcie 8, respectively.
If a user needs to connect two adapter cards, such as solid state disks, corresponding to the expansion slot pcie 4 on the motherboard, the switch device 1 may be controlled to be in the second state, so that the motherboard includes two expansion slots pcie 4 and one expansion slot pcie 8, and the two solid state disks are inserted into the expansion slot pcie 4 respectively.
If a user needs to connect an adapter card corresponding to the expansion slot pcie 16 on the motherboard, the switch 1 and the switch 2 may be controlled to be in the first state, so that the motherboard includes an expansion slot pcie 16, and the adapter card may be inserted.
Next, description will be made of "a plurality of expansion slots connected to the switch member to form one target expansion slot when the switch member is in the first state". There are various cases of "a plurality of expansion slots connected to the switch member in the first state to form a target expansion slot", and the embodiments of the present application provide, but are not limited to, the following two.
The first method comprises the following steps: if the plurality of switch pieces are all in the first state, and for any one of the plurality of switch pieces, the switch pieces which are connected with the same expansion slots with the switch pieces exist in the plurality of switch pieces, the plurality of expansion slots which are respectively connected with the plurality of switch pieces are connected to form one target expansion slot.
It can be understood that, if any one of the plurality of switch pieces and a switch piece connected with the same expansion slot as the switch piece exists in the plurality of switch pieces, it means that the plurality of expansion slots connected with the plurality of switch pieces respectively are connected. The following examples are given.
Assuming that the number of the plurality of switching elements is 3, and the switching elements are switching element 1, switching element 2 and switching element 3; 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; switch 3 is connected to expansion slot B2 and expansion slot C1, respectively. For the switch 1, the switch 2 and the switch 1 are connected with the same expansion slot A1 in the 3 switches; for the switch 2, the same expansion slot a1 is connected to the switch 1 and the switch 2 in 3 switches; for switch 3, there is the same expansion slot B2 connected to switch 2 and switch 3 among the 3 switches. If the switch piece 1, the switch piece 2 and the switch piece 3 are all 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 to form a target expansion slot.
Fig. 3 is a schematic diagram of a target expansion slot formed when 3 switch pieces are in a first state according to an embodiment of the present application.
Fig. 3 illustrates an example in which each switch is connected to two expansion slots. The number of transmission channels allocated by the processor for the two expansion slots connected by each switch element is shown in fig. 3. After the 3 switches 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.
And the second method comprises the following steps: 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 of the switch pieces are connected with each other to form a target expansion slot.
The expansion slots respectively connected with one or more switch pieces are different, so that for each switch piece, a plurality of expansion slots connected with the switch piece are connected and are not connected with expansion slots connected with different switch pieces, so that a plurality of expansion slots connected with the same switch piece are connected and form a target expansion slot.
In an optional implementation manner, when the switch piece connected to the expansion slot is in the second state, the expansion slot is an original independent expansion slot.
It can be understood that, when the switch member connected to the expansion slot is in the second state, 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 a 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. That is, the electronic device may include one or more target expansion slots, and/or one or more stand-alone expansion slots.
The following is a description of how to control the state of the switch member. There are various ways to control the switch member to be in the corresponding state, and the embodiments of the present application provide, but are not limited to, the following two.
First, software control.
The switch member may be controlled by the processor to be in the first state or the second state.
Illustratively, the switch element is a transistor, for example, a diode or a triode, 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 element from the plurality of switch elements based on the target slot type and controls the target switch element to be in the first state.
Illustratively, the target switch element includes one or more switch elements, and a sum of the first numbers respectively corresponding to the plurality of expansion slots connected to the target switch element is a number corresponding to the type of the target slot.
Illustratively, if one or more of the switching elements are 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.
And after the target switch piece is controlled to be in the second state, the sum of the first numbers respectively corresponding to the plurality of expansion slots connected with the switch piece in the first state is the number corresponding to the type of the target slot.
And the 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 disconnected with the connecting piece in a matched mode, so that the switch piece is in a second state.
For example, the switch member is a groove, and the connection member is a protrusion that fits in the groove.
Illustratively, the switch member may be manually operated to be connected with the connecting member in a fitting manner, or the switch member may be disconnected from the connecting member in a fitting manner.
Illustratively, the software control can be used for making the switch member be matched with and connected with the connecting member or making the switch member be matched with and disconnected from the connecting member.
In an alternative implementation, the electronic device further includes a switching circuit 16, the number of input terminals of the switching circuit 16 is the same as the number of switch elements provided on the main board, and one input terminal of the switching circuit 16 is connected to one switch element. An output of switching circuit 16 is coupled to processor 12.
Fig. 4 is a circuit diagram of another implementation manner of an electronic device according to an embodiment of the present application.
Illustratively, the switching element is in a different state than the signal detected at the input to which the switching element is connected.
Illustratively, a signal may be detected at each input of the switching circuit; the signals detected at all the inputs of the switching circuit constitute the input signals of the switching circuit.
Illustratively, the switching element is in a first state, and the signal detected by the input end connected with the switching element is ON; the switching element is in a second state and the signal detected at the input connected to the switching element is OFF.
The correspondence between the input signal and the output signal is exemplified below.
Assuming that the number of the switches is 2, and the switches are switch 1 and switch 2, respectively, assuming that the number of the expansion slots connected to the motherboard is 3, and the expansion slots are expansion slot pcie 4, expansion slot pcie 4, and expansion slot pcie 8, respectively; the switch 1 is connected to two expansion slots pcie 4, and the switch 2 is connected to one expansion slot pcie 4 and one expansion slot pcie 8, respectively.
For example, the output signals of the switching circuits corresponding to different input signals are different, and the layout patterns of the expansion slots corresponding to different output signals are different. The corresponding relationship between the output signal and the expansion slot layout pattern is preset, and the following illustrates the corresponding relationship between the input signal, the output signal and the expansion slot layout pattern, as shown in table 1.
TABLE 1
Illustratively, the number of output terminals of the switching circuit is related to the number of output signals, and illustratively, if the number of output terminals of the switching circuit is N and the number of output signals is L, then 2NIs more than or equal to L. For example, if there are 2 output signals, the number of the output terminals of the switching circuit may be 1, and the output signal of the output terminal of the switching circuit may be two signals, i.e., a high level signal and a low level signal; if there are 3 output end signals, the number of the output ends of the switching circuit can be 2, and there can be 4 combinations of the signals output by the output end 1 and the output end 2, namely 3.
Illustratively, a low level signal may be represented by 0 and a high level signal may be represented by 1.
Illustratively, the output terminal of the switching circuit may be connected to the pin of the processor, and if the number of the output terminals of the switching circuit is 2, the output terminal 1 of the switching circuit may be connected to the pin CFG6 of the processor, and the output terminal 2 may be connected to the pin CFG5 of the processor.
It can be understood that, if the number of the expansion slots connected to the motherboard is assumed to be 4, and the expansion slots are expansion slot pcie 4, expansion slot pcie 4, expansion slot pcie 8, and expansion slot pcie 8; if the formed target expansion slot is the expansion slot pcie 16, two expansion slots pcie 8 may be formed, or two expansion slots pcie 4 and one expansion slot pcie 8 may be formed. If the target expansion slot is formed by two expansion slots pcie 8, the processor needs to provide 16 transmission channels for the two expansion slots pcie 8; if the target expansion slot is formed by two expansion slots pcie 4 and one expansion slot pcie 8, the processor needs to provide 16 transmission channels for the two expansion slots pcie 4 and the one expansion slot pcie 8. If the target expansion slot is formed by two expansion slots pcie 4 and one expansion slot pcie 8, the processor provides 16 transmission channels for the two expansion slots pcie 8, which cannot be realized by 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 an identification of a plurality of expansion slots forming the target expansion slot, and/or an identification of the original independent expansion slot.
Illustratively, the identification of the expansion slot characterizes the position 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 can be implemented by adopting various forms of processes, so that the present application also discloses a method, and specific embodiments are described in detail below.
As shown in fig. 5, a flowchart of an expansion slot channel allocation method provided in this embodiment of the present application, which may be applied to a processor of an electronic device, includes the following steps S51 to S53.
Step S51: a target signal is obtained.
Illustratively, the target signal is an output signal of the switching circuit.
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 comprises: an extension slot identifier set corresponding to the target extension slot and/or an identifier of an independent extension slot, where the extension slot identifier set includes identifiers of a plurality of extension slots forming the target extension slot, and each extension slot layout mode includes: an identification of an expansion slot forming the target expansion slot, and/or an identification of an independent expansion slot.
For example, if the switch elements respectively connected to the expansion slots connected to the processor are all in the second state, the 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 expansion slots connected to the processor are all in the first state, the 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 set corresponding to the one or more target expansion slots.
For example, if a part of the switch elements respectively connected to the plurality of expansion slots connected to the processor is in the first state and a part of the switch elements is in the second state, a target expansion slot is formed by a part of the plurality of expansion slots connected to the processor, and a part of the plurality of expansion slots is still the original independent expansion slot. The corresponding expansion slot layout pattern includes: a set of expansion slot identifications corresponding to the one or more target expansion slots, and identifications of the one or more independent expansion slots.
For example, it may be default that the switch pieces respectively connected to the plurality of expansion slots connected to the processor are in the second state; therefore, the expansion slot layout pattern may only include the expansion slot identifier set corresponding to the target expansion slot, and the other expansion slots are defaulted to be independent expansion slots.
Step S53: assigning the second number of transmission channels in total for expansion slots having an identification of an expansion slot forming the target expansion slot based on the target expansion slot layout pattern, and/or assigning the first number of transmission channels for expansion slots having an identification of an independent expansion slot.
In an alternative implementation manner, there are various implementation manners of step S51, and the present embodiment provides, but is not limited to, a method including step a1 to step a 2.
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.
There are various implementations of the switching circuit, and the embodiments of the present application provide, but are not limited to, the following two.
The first implementation mode comprises the following steps: and (4) controlling by software.
The correspondence relationship between the input signal and the output signal detected by the switching circuit is set in the switching circuit in advance.
Illustratively, the switching circuit is 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 comprises the following steps: 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.
Illustratively, the switching tube may be a transistor, such as a diode or a triode.
In the following description, the switching circuit is illustrated by way of example, and it is assumed that the input signal of the switching circuit is equal to the output signal, and one circuit corresponds to each input terminal of the switching circuit. The circuits corresponding to 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.
