The device information can characterize the device type, i.e. the function type, of the corresponding communication interface, and the device information and its corresponding device type can be shown in table 1 below. One piece of device information, i.e., the target device information of the target device type, can be uniquely determined based on the target device type, and the target device information is taken as the current device information of the target communication interface.

In the embodiment of the present invention, when the control end 101 is started and initialized, a base address information is allocated to each device, where the base address information on one hand establishes a mapping relationship with the device address information inside the communication interface chip 102, on the other hand establishes a mapping relationship with the storage space allocated in the control end 101, so as to establish a mapping relationship as an intermediate address between the device address information inside the communication interface chip 102 and the storage space allocated in the control end 101.
As an alternative embodiment, when the same type of device 103 is not present in the plurality of devices 103, the corresponding base address information can be uniquely determined based on the device information, and then the corresponding target device information and the target base address information can be uniquely determined based on the target device type of the target communication interface.
As an alternative embodiment, when the same type of device 103 exists among the plurality of devices 103, the device information of these same type of devices 103 is the same, but the base address information is different, and the distinction is made by the base address information.
Alternatively, when the target device type of the target communication interface obtained by the control end 101 is a device type in which a plurality of devices 103 exist, if no specific device is specified in the user update requirements obtained by the control end 101, it is possible to search for base address information of a device 103 that is not enabled among the devices 103 whose device type is the target device type, and select one base address information from among them as the target base address information of the target communication interface, that is, select one device 103 to be enabled from among the devices 103 that are not enabled.
Alternatively, when the target device type of the target communication interface obtained by the control end 101 is a device type in which a plurality of devices 103 exist, if a specific device is specified in the user update requirement obtained by the control end 101, for example, the devices of the same device type may be numbered to form a distinction, then the base address information of the specified device may be directly used as the target base address information of the target communication interface.
Step S203, a mapping relationship is established between the current base address information and the device address information of the target device type.
In the embodiment of the invention, the device address information is preset address information respectively corresponding to each device type. The device address information is address information built in the communication interface chip 102, which characterizes the address space base address inside the communication interface chip 102, i.e., the start address of the address space inside the communication interface chip 102, for each device type, i.e., each device.
In the embodiment of the present invention, the communication interface chip 102 establishes a mapping relationship between the current base address information and the device address information corresponding to the target communication interface, so as to map the read-write operation to the current base address information. And then, a mapping relation is established between the current base address information corresponding to the target communication interface and the storage space in the control end 101 through the control end 101, so that a mapping relation is established between the equipment address information of the target communication interface and the storage space in the control end 101, the operation of the target communication interface is mapped into the storage space in the control end 101, and the bus access operation of the target communication interface is mapped onto the corresponding equipment.
According to the communication interface function configuration method provided by the embodiment, the current configuration information of the target communication interface is reconfigured according to the type of the target equipment of the target communication interface, so that the mapping relation is established between the target communication interface and the target equipment again, and flexible configuration of the communication interface function is realized.
In this embodiment, a communication interface function configuration method is provided, which may be used in the integrated circuit, the apparatus or the device accessing the communication interface chip 102, and fig. 3 is a flowchart of another communication interface function configuration method according to an embodiment of the present invention, and as shown in fig. 3, the flowchart includes the following steps:
Step S301, receiving a target device type of a target communication interface sent by a control end. Please refer to step S201 in the embodiment shown in fig. 2 in detail, which is not described herein.
Step S302, determining current configuration information of the target communication interface based on the target device type.
Specifically, the step S302 includes:
in step S3021, target configuration information of a target communication interface is determined based on a target device type.
In the embodiment of the present invention, since the target communication interface may be performing a read-write operation, at this time, the current configuration information of the target communication interface is directly reconfigured, which may cause interruption of the current read-write operation and cause abnormal read-write operation, so when the communication interface chip 102 receives the target device type of the target communication interface, the configuration information is prepared, but the current configuration information of the target communication interface is not directly updated, that is, the target configuration information of the target communication interface is first determined.
As an alternative embodiment, the step S3021 may include:
and a1, determining target equipment information and target address information corresponding to the target equipment type.
In the embodiment of the invention, firstly, the corresponding target equipment information and target address information are determined based on the type of the target equipment of the target communication interface. The target equipment information is equipment information corresponding to the type of the target equipment; the target address information is address information corresponding to the type of the target device, and is set correspondingly as described in step S202.
And a step a2 of configuring target address space information of the target communication interface based on the target address information.
In the embodiment of the invention, the target address information comprises target space information and target base address information. The space information is the same as the device address information, and is the information built in the communication interface chip 102, each device address information has corresponding space information, and the space size of the address space information of the communication interface is consistent with the space size of the device address information corresponding to the device address information, so that when determining the target address information, the space information of the device address information corresponding to the target device type, that is, the target space information, needs to be determined.
In the embodiment of the present invention, as described in the above step S202, the destination address information of the destination communication interface is determined based on the destination device type.
As an alternative embodiment, the step a2 may include:
step a21, determining the size of the target address space based on the target space information.
In the embodiment of the invention, the target space information characterizes the space size of the device address information corresponding to the target device type, and simultaneously characterizes the space size of the corresponding target address space. Therefore, the space size of the target address space can be determined based on the target space information.
Step a22, determining the address segment range of the target address space of the target communication interface based on the target base address information and the size of the address space to determine the target address space information.
In the embodiment of the invention, the target base address information is used as the initial address of the address segment of the target address space, and then the address segment range of the target address space is determined by combining the size of the address space, so that the target address space information is obtained. All read-write operations mapped in the target address space information range are read-write operations aiming at the target communication interface.
In step S3022, in response to the function update request, the target configuration information is determined as the current configuration information of the target communication interface.
In the embodiment of the present invention, when the current read-write operation of the target communication interface in the control terminal 101 is completed, it indicates that the configuration information of the target communication interface can be updated, and the function of the target communication interface is reconfigured, and at this time, the control terminal 101 generates a function update request. Accordingly, the communication interface chip 102 determines the target configuration information as the current configuration information in response to the function update request to complete the configuration update of the target communication interface.
As an alternative embodiment, a device function register may be provided in the communication interface chip 102, where a reset function bit is provided, and the function update request is implemented through the reset function bit. When the communication interface chip 102 is just started, the reset function bit is enabled, so that the reset function bit is activated, and the assignment of the reset function bit can correctly reflect the requirement of requesting function update.
As an alternative embodiment, when the current read/write operation of the target communication interface in the control terminal 101 is completed, the reset function bit of the device function register is assigned to 1. When the value of the reset function bit is 1, the communication interface chip 102 generates a response, i.e., in response to the function update request, to determine the target configuration information as the current configuration information.
As an alternative embodiment, the current configuration information includes current device information, current base address information, and current address space information corresponding to the target configuration information. Based on this, the step S3022 may include: determining the target equipment information as the current equipment information of the target communication interface; determining the target base address information as the current base address information of the target communication interface; and determining the target address space information as current address space information of the target communication interface.
Step S303, a mapping relationship is established between the current base address information and the device address information of the target device type. Please refer to step S203 in the embodiment shown in fig. 2 in detail, which is not described herein.
According to the communication interface function configuration method provided by the embodiment, the configuration information of the target communication interface is not directly updated, but after the current read-write operation of the target communication interface is completed, the function update request is regenerated successfully, the communication interface chip 102 responds to the function update request, the configuration of the target communication interface is updated, the read-write abnormality caused by the interruption of the current read-write operation is avoided, and the reliability of the communication interface chip 102 is ensured.
In this embodiment, a communication interface function configuration method is provided, which may be used in the integrated circuit, the apparatus or the device accessing the communication interface chip 102, and fig. 4 is a flowchart of another communication interface function configuration method according to an embodiment of the present invention, and as shown in fig. 4, the flowchart includes the following steps:
step S401, a target device type of a target communication interface is acquired, and the target device type is sent to a communication interface chip.
In the embodiment of the present invention, the control end 101, as a platform for interaction with a user, can obtain a configuration requirement of the user on a communication interface function, including a communication interface that needs to update a function, i.e., a target communication interface, and a function that needs to be updated by the target communication interface, i.e., a target device type. The control terminal 101 sends the target device type of the target communication interface to the communication interface chip 102, so that the communication interface chip 102 starts to reconfigure and switch the functions of the communication interface based on the target device type of the target communication interface.
Step S402, a current device type of a plurality of communication interfaces is acquired.
In the embodiment of the present invention, in order to reallocate the storage space in the control end 101, after the communication interface chip 102 reconfigures the current configuration information of the target communication interface, the current device type of each communication interface in the communication interface chip 102 is obtained.
As an alternative implementation manner, after the communication interface chip 102 completes the reconfiguration of the current configuration information of the target communication interface, a signal may be generated by an external power-up manner or the like to inform the control terminal 101 that the communication interface chip 102 has completed the related operation about the functional configuration of the target communication interface, and the control terminal 101 may reallocate the storage space of each communication interface.
Step S403, based on the current device types of the plurality of communication interfaces, allocates storage space for the plurality of communication interfaces, and establishes a mapping relationship between the allocated storage space and the current base address information of the communication interface chip.
In the embodiment of the invention, the storage space can be allocated for each communication interface according to the communication protocol corresponding to the communication interface. Meanwhile, in order to map the bus access operation of the target communication interface onto the corresponding device, a mapping relationship is established between the storage space allocated by the control end 101 and the current base address information corresponding to the target communication interface in the communication interface chip 102, the read-write operation mapped to the current base address information may be mapped into the storage space, so that a mapping relationship is established between the device address information of the target communication interface and the storage space in the control end 101, and thus the operation on the target communication interface is mapped into the storage space in the control end 101.
Step S404, based on the current device types of the plurality of communication interfaces, loading device drivers of the target devices corresponding to the plurality of communication interfaces.
In the embodiment of the present invention, in order to configure the function of the communication interface to the corresponding device, not only a mapping relationship needs to be established between the device address information of the target communication interface and the storage space in the control end 101, but also a device driver of the corresponding target device needs to be loaded, so that the corresponding target device can be invoked and operated, thereby providing a hardware base for the function configuration of the communication interface. Therefore, the device type of the communication interface can be updated according to the requirements, the storage space is redistributed, and corresponding device drivers are loaded, so that the flexible configuration of the communication interface functions is realized.
In this embodiment, a communication interface function configuration method is provided, which may be used in the integrated circuit, the apparatus or the device accessing the communication interface chip 102, and fig. 5 is a flowchart of a further communication interface function configuration method according to an embodiment of the present invention, as shown in fig. 5, where the flowchart includes the following steps:
step S501, a target device type of a target communication interface is acquired, and the target device type is sent to a communication interface chip. Please refer to step S401 in the embodiment shown in fig. 4 in detail, which is not described herein.
Step S502, stopping the read-write operation of the target communication interface and initiating a function update request to the communication interface chip when the target communication interface finishes the current read-write operation or the target communication interface does not perform the read-write operation.
In the embodiment of the present invention, since the target communication interface may be performing a read-write operation, at this time, the current configuration information of the target communication interface is directly reconfigured, which may cause interruption of the current read-write operation and cause abnormal read-write operation, so that the communication interface 102 is informed when to reconfigure the current configuration information of the target communication interface by setting a function update request. Specifically, when the target communication interface finishes the current read-write operation or the target communication interface does not perform the read-write operation, a function update request is initiated to the communication interface chip, and meanwhile, the read-write operation of the target communication interface is stopped, so that the read-write abnormality is avoided.
Therefore, the configuration information of the target communication interface can be fully updated after the current read-write operation of the target communication interface needing to reconfigure the function is completely finished, the integrity of data read-write is guaranteed, and the reliability of the communication interface is improved.
Step S503, obtaining the current device types of the plurality of communication interfaces. Please refer to step S402 in the embodiment shown in fig. 4 in detail, which is not described herein.
Step S504, based on the current equipment types of the plurality of communication interfaces, storage space is allocated for the plurality of communication interfaces, and a mapping relation is established between the allocated storage space and the current base address information of the communication interface chip.
In the embodiment of the present invention, the device types of some of the plurality of communication interfaces are not modified, that is, the current device types of the communication interfaces are consistent with the historical device types, the communication interface chip 102 does not reconfigure the configuration information for the communication interfaces, and then the storage space of the communication interfaces does not need to be reconfigured. When the current device type of the communication interface is inconsistent with the historical device type, namely when an updated communication interface with the inconsistent current device type and the historical device type exists in the plurality of communication interfaces, the configuration information of the updated communication interface is obtained in a reconfiguration mode, at the moment, a storage space is required to be allocated for the updated communication interface, and a mapping relation is established between the storage space and the current base address information of the communication interface chip. Therefore, only the storage space is allocated for the communication interfaces with the reconfiguration function, the memory space can be allocated reasonably, and the work of other communication interfaces without the reconfiguration function is not influenced.
As an alternative implementation manner, the communication interfaces are updated, that is, the target communication interfaces described above, but the control end 101 cannot directly know which of the plurality of communication interfaces in the communication interface chip 102 is the current communication interface with the configuration information reconfigured, but can only acquire the current device type of the communication interfaces, and determines which communication interfaces have the configuration information changed according to the current device type and the historical device type of the communication interfaces, thereby determining the communication interfaces needing to reallocate the storage space, that is, the updated communication interfaces, or the target communication interfaces.
As an alternative implementation, when the function of the communication interface is reconfigured, the memory space occupied by the communication interface before being reconfigured is released, and the stored data is cleared; i.e. the originally occupied memory space of the target communication interface or the updated communication interface is released and the originally stored data is cleared.
As an alternative implementation manner, when the storage space is allocated, the memory may be allocated for each target communication interface or updated communication interface directly according to the communication protocol corresponding to the communication interface.
As an alternative implementation manner, when the storage space is allocated, the storage space occupied by the target communication interface or the updated communication interface before being reconfigured may be used as the storage space of the corresponding device before the target communication interface or the updated communication interface is not reconfigured, and when the function of the other communication interface is configured as the device, the storage space is re-enabled.
In step S505, based on the current device types of the plurality of communication interfaces, device drivers of the target devices corresponding to the plurality of communication interfaces are loaded.
In the embodiment of the present invention, the device types of some of the plurality of communication interfaces are not modified, that is, the current device types of the communication interfaces are consistent with the historical device types, the communication interface chip 102 does not reconfigure the configuration information for the communication interfaces, and then the storage space of the communication interfaces does not need to be reconfigured. When the current device type of the communication interface is inconsistent with the historical device type, namely when an updated communication interface with the inconsistent current device type and the historical device type exists in the plurality of communication interfaces, the configuration information of the updated communication interface is obtained through reconfiguration, and at the moment, a device driver corresponding to the updated communication interface needs to be loaded to provide a hardware basis for the functional configuration of the communication interface.
As an alternative embodiment, a security authentication may also be established between the communication interface chip 102 and the control terminal 101. Specifically, the initial device information and the vendor information of a part of the communication interfaces in the communication interface chip 102 may be set to 0xff, and when the communication interface chip 102 is connected to the control terminal 101, the control terminal 101 cannot normally identify the device types of the communication interfaces, and thus cannot use the communication interfaces. Meanwhile, a key is set in the communication interface chip 102 or the control terminal 101 to perform security verification, and a third party interface, such as a universal asynchronous receiver Transmitter (Universal Asynchronous Receiver/Transmitter, UART) interface, is introduced, through which communication between the control terminal 101 and the communication interface chip 102 is established, so that security verification of the key is completed, and after the security verification is passed, the target device type and the target vendor type of the communication interface in the communication interface chip 102 by the control terminal 101 are still transmitted to the communication interface chip 102 through the third party interface, so that the communication interface chip 102 configures a corresponding communication interface according to the target device type, thereby opening the communication interface to the control terminal 101. By establishing a security verification between the communication interface chip 102 and the control terminal 101, a specific communication interface can be enabled after the security verification is passed, and the security and reliability of the communication interface chip 102 are improved.
