It is noted that the structure shown in fig. 1 does not constitute a limitation of the identification means of the access device, which may comprise more or less components than those shown in fig. 1, or a combination of certain components, or a different arrangement of components, in addition to those shown in fig. 1.
Based on the introduction of the hardware architecture of the host, an embodiment of the present application provides an identification method for an access device, and the following describes the identification method for an access device provided in the embodiment of the present application with reference to the accompanying drawings.
As shown in fig. 2, the identification method of the access device may include the following steps 201 to 203.
201. And under the condition that the computer equipment detects that the access equipment is inserted into the slot, determining the target bit width of the access equipment based on the detection chip.
Optionally, the slot is a reverse-configured PCIE (peripheral component interconnect express) slot, and the type of the slot may be X16.
In a specific implementation, after the computer device is started, whether the access device is inserted into the slot may be detected, and if the access device is inserted into the slot, the bit width of the access device may be determined by detecting the chip.
202. And the computer equipment acquires a target communication mode according to the target bit width.
The target communication mode is a communication mode adopted by data interaction between the computer equipment and the access equipment.
It should be noted that, according to the usage characteristics of the slot set in the flip, the access devices with different bit widths correspond to different communication modes, so that the target communication mode of the access device can be determined and acquired according to the bit width of the access device.
203. And the computer equipment adopts a target communication mode to perform data interaction with the access equipment.
In a specific implementation, the computer device may obtain the target communication mode of the access device according to the bit width of the access device, so as to implement data interaction between the computer device and the access device.
According to the method for identifying the access device, the target bit width of the access device inserted into the slot is identified through the detection chip, the target communication mode is obtained according to the target bit width, and data interaction is performed between the target communication mode and the access device, so that the inverted slot can identify the access device with more than one bit width type, and the use flexibility of the inverted slot can be improved. Meanwhile, the identification of the turned slot to the access equipment with different bit width types is realized through the existing detection chip on the mainboard, no additional device is required to be added, and no additional program for identifying the access equipment is required to be developed and maintained, so that the implementation cost can be reduced.
Optionally, in this embodiment of the application, as shown in fig. 3, the socket may include a first pin, and the detection chip may include a first port, where the first pin is connected to the first port. The computer device in step 201 determines the target bit width of the access device based on the detection chip, and the specific process is as follows: the computer equipment transmits a first detection signal to the slot through the first port, can detect a first level state of the first port after transmitting the first detection signal, and determines a target bit width of the access equipment according to a mapping relation between a pre-stored first level state and the bit width.
It is understood that the first PIN may be the PIN #81 PIN of the socket. The first port may be a first preset port of a General-purpose input/output (GPIO) of the detection chip.
In an actual implementation process, after the computer device is started, the detection chip may periodically transmit a first detection signal to the slot by using the first port. When an access device of a different bit width type is inserted into the slot, a change in the state of the level of the first detection signal is caused. Therefore, after the detection chip transmits the first detection signal, the first level state of the first port can be detected in real time, and the target bit width of the access device is determined according to the mapping relation between the first level state and the bit width.
Specifically, the first level state may be a high level or a low level, and different level states correspond to different bit widths.
For example, when the first level state is a low level, the detection chip may determine that the target bit width of the access device inserted into the slot is X16. When the first level state is a high level, the detection chip may determine that the target bit width of the access device inserted into the slot is a preset bit width other than X16, for example, the preset bit width may be X8. Of course, the mapping relationship between the first level state and the bit width is not limited to the above example. The first level state of the low level may correspond to a bit width of X8, and the first level state of the high level may correspond to a bit width of X16.
Optionally, in this embodiment of the application, as shown in fig. 3, the socket may further include a second pin, and the detection chip may include a second port. And the second pin is connected with the second port. The specific process of detecting that the chip is inserted into the slot in step 201 includes: the detection chip transmits a second detection signal through the second port, detects a second level state of the second port after the detection chip transmits the second detection signal, and determines that the access device is inserted into the slot under the condition that the second level state is in a preset state.
It is understood that the second PIN may be a PIN # 17 PIN of the socket, and the second port may be a second preset port of the GPIO port of the detection chip.
In an actual implementation process, the detection chip may transmit a second detection signal to the slot by using the second port, and detect the level state of the second port after transmitting the second detection signal to obtain a second level state. And then judging whether the second level state is in a preset state, if the level state of the second port is in the preset state, determining that the access equipment is inserted into the slot, and if the level state of the second port is not in the preset state, indicating that the access equipment is not inserted into the slot.
For example, the preset state may be a high level or a low level, and the second level state may be a high level or a low level. If the preset state is a low level, the detection chip may determine that the access device is inserted into the slot when determining that the second level state is a low level. The detection chip may determine that no access device is inserted into the slot when it is determined that the second level state is the high level. Of course, the relationship between the preset state and whether the access device is inserted into the slot is not limited to the above example. When the preset state is the high level, the detection chip may determine that the access device is inserted into the slot when the second level state is determined to be the high level. And when the detection chip determines that the second level state is low level, determining that no access equipment is inserted into the slot. The embodiment of the application does not limit the relationship between the preset state and whether the access device is inserted into the slot, and the preset state and the relationship can be configured in advance according to actual requirements.
Optionally, in this embodiment, as shown in fig. 3, the detection chip may further include a third port. The specific process of the computer device obtaining the target communication mode according to the target bit width in step 202 includes: and the detection chip sets a third level state of the third port according to the target bit width. Therefore, the processor can acquire the target communication mode corresponding to the third level state according to the mapping relation between the prestored third level state and the communication mode.
The third port may be a third preset port of the GPIO port of the detection chip. The level state of the third port includes a high level and a low level, and the communication mode may include an X16 mode and an X8 mode.
In an actual implementation process, the detection chip may determine a target bit width of the access device according to the level state of the first port, and then may set the level state of the third port according to the level state of the first port. For example, if the level state of the first port is low, the level state of the third port is set to low. And if the level state of the first port is high level, setting the level state of the third port to be high level. The processor may then obtain a target communication mode corresponding to the third level state according to a mapping relationship between the third level state and the communication mode, so as to select a target communication mode suitable for communication for the access device inserted into the slot.
Optionally, in this embodiment of the application, a bus is further disposed on the motherboard, and the slot and the detection chip are connected through the bus. The method for identifying the access device provided by the embodiment of the application may further include: and the computer equipment performs parameter configuration on the bus according to the target communication mode.
In this case, the computer device in step 203 adopts the target communication mode, and the specific implementation manner of performing data interaction with the access device is that the computer device adopts a bus after parameter configuration to perform data interaction with the access device.
Optionally, in this embodiment, specifically, the processor may set the usage number of the bus according to the target communication mode. For example, if the target bit width of the access device is X16, the processor may determine that the target communication mode is X16 and configure the number of bus uses to be 16. That is, if the target bit width of the access device is X16, the processor performs data interaction with the access device using 16 lines in the bus. If the target bit width of the access device is X8, the processor may determine that the target communication mode is X8. In this case, the processor may use 8 lines in the bus for data interaction with the access device.
