The configuration of the PHY chip can be divided into hardware configuration and software configuration.

[0003] In the related art, since the PHY chip only supports MDIO (Management Data Input / Output) interface communication, most system devices cannot directly access the internal registers of the PHY chip. Therefore, to realize the configuration function of the PHY chip, the system device generally needs to first configure an SFP (Small Form Pluggable) interface module through I2C (Inter-Integrated Circuit), and then the interface module configures the PHY chip through MDIO. However, the communication rate of I2C is difficult to adapt to the case of high speed requirement, and the SFP interface module only supports I2C protocol, so that the system device can only configure the PHY chip through the I2C interface. There are problems such as low port adaptability and low transmission rate.

[0046] The core of this application is to provide a method, apparatus, computing device, and computer-readable storage medium for configuring physical interface chips, thereby improving the transmission efficiency of configuration data based on existing interfaces.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] In related technologies, because PHY chips only support MDIO interface communication, most system devices cannot directly access the PHY chip's internal registers. Therefore, to configure the PHY chip, the system device typically needs to first configure the SFP interface module via I2C, and then the interface module configures the PHY chip via MDIO. However, the communication rate of I2C is difficult to adapt to high-speed requirements, and the SFP interface module only supports the I2C protocol, forcing system devices to configure the PHY chip only through the I2C interface. This results in problems such as low port compatibility and low transmission rates.

[0049] Therefore, this application provides a method for configuring a physical interface chip. First, the data to be parsed is obtained from the bus interface. Then, the data to be parsed is parsed according to the communication format corresponding to the bus interface to obtain configuration data. Finally, the configuration data is sent to the physical interface chip according to the MDIO communication format to realize the corresponding software configuration. This eliminates the need to connect an interface conversion module, improves transmission efficiency, and can also handle data transmitted from different buses, thus improving adaptability.

[0050] The following embodiment illustrates a method for configuring a physical interface chip provided in this application.

[0051] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a method for configuring a physical interface chip, as provided in an embodiment of this application.

[0052] In this embodiment, the method may include:

[0053] S101, obtain the data to be parsed from the bus interface;

[0054] This step aims to obtain the data to be parsed from the bus interface. In this embodiment, the main focus is on software configuration of the physical interface chip, i.e., sending configuration data to the physical interface chip. In existing technologies, the configuration data is typically sent to the physical interface chip via a bus interface adapter, which can easily lead to reduced data transmission efficiency. Therefore, the technical solution of this application obtains the data to be parsed directly from the bus interface. This data to be parsed includes configuration data for software configuration.

[0055] The data to be parsed is encapsulated in the communication format corresponding to the bus. Normally, data from this bus interface cannot be directly sent to the physical interface chip. Therefore, in this embodiment, the data is transmitted through a parsing and transmission process, improving the compatibility with the configuration chip.

[0056] Furthermore, this step may include:

[0057] The FPGA obtains the data to be parsed from the bus interface.

[0058] As can be seen, this alternative solution can also acquire the data to be parsed based on an FPGA (Field Programmable Gate Array). The FPGA can improve the efficiency of data processing and avoid slowing down the data processing speed.

[0059] S102, based on the communication format corresponding to the bus interface, parse the data to be parsed to obtain the configuration data;

[0060] Based on S101, this step aims to parse the data to be parsed based on the communication format corresponding to the bus interface to obtain the configuration data.

[0061] Furthermore, in this step, the data frame of the data to be parsed can be redefined based on the MDIO communication format. That is, the parts of the data to be parsed that are the same as those in the MDIO format are mapped to ensure that the data to be parsed can be effectively transmitted to the physical interface chip.

[0062] Furthermore, this step may include:

[0063] Step 1: Match the corresponding communication format based on the interface information of the bus interface;

[0064] Step 2: Parse the data to be parsed based on the communication format to obtain the configuration data.

[0065] As can be seen, this optional solution mainly describes how to parse and obtain configuration data. In this optional solution, the interface information of the bus interface is matched with the corresponding communication format; based on the communication format, the data to be parsed is parsed to obtain the configuration data. That is, first, it is determined what kind of bus the bus interface is, then the format corresponding to that bus is determined, and the data to be parsed is parsed to obtain the configuration data. The configuration data includes not only the data used for configuration but also parameter information constituting MDIO data. Therefore, the configuration data can include operands, physical interface chip addresses, device addresses, and communication data in MDIO communication.

[0066] S103 sends configuration data to the physical interface chip based on the MDIO communication format, so that the physical interface chip can perform software configuration based on the configuration data.

[0067] Building upon S102, this step aims to send configuration data to the physical interface chip using the MDIO communication format, so that the physical interface chip can perform software configuration based on the configuration data.

[0068] The number of physical interface chips can be one or more. When multiple physical interface chips are present, the chip selection information can be used to select the corresponding chip and send the data.

[0069] The physical interface chip communicates with the outside world only through its MDIO interface. Therefore, this step involves sending data to the chip in the MDIO communication format so that the chip can receive the corresponding data and perform software configuration.

[0070] Furthermore, this step may include:

[0071] Step 1: Convert the configuration data based on the MDIO communication format to obtain MDIO frames;

[0072] Step 2: Send the MDIO frame to the physical interface chip.

[0073] As can be seen, this optional solution mainly describes how to send configuration data. In this optional solution, the configuration data is converted based on the MDIO communication format to obtain MDIO frames; the MDIO frames are then sent to the physical interface chip. The process of converting the configuration data based on the MDIO communication format can employ any conversion method provided by existing technology, and is not specifically limited here.

[0074] Furthermore, this step may include:

[0075] The configuration data is sent to the MDIO interface of the physical interface chip using the MDIO communication format, so that the physical interface chip can receive the configuration data from the MDIO interface.

[0076] As can be seen, this optional solution mainly describes how to send configuration data. In this optional solution, the configuration data is sent to the MDIO interface of the physical interface chip based on the MDIO communication format, so that the physical interface chip can receive the configuration data from the MDIO interface.

[0077] Furthermore, this embodiment may also include:

[0078] Step 1: In response to the read operation command, obtain the data to be read from the physical interface chip based on the MDIO communication format;

[0079] Step 2: Convert the data to be read into the corresponding communication frame based on the communication format of the bus corresponding to the read operation instruction;

[0080] Step 3: Send a communication frame through the bus corresponding to the read operation command.

[0081] As can be seen, this optional solution mainly describes how to read data from the physical interface chip. In this optional solution, in response to a read operation command, the data to be read is obtained from the physical interface chip based on the MDIO communication format; the data to be read is converted into a corresponding communication frame based on the communication format of the bus corresponding to the read operation command; and the communication frame is sent through the bus corresponding to the read operation command. In other words, when an external device needs to read data from the physical interface chip, it can obtain the data through the reverse process described above. That is, the data to be read is obtained from the physical interface chip based on the MDIO communication format; the data to be read is converted into a corresponding communication frame based on the communication format of the bus corresponding to the read operation command; and the communication frame is sent through the bus corresponding to the read operation command. The data to be read is contained in the communication frame.

[0082] Furthermore, this embodiment may also include:

[0083] Step 1: Obtain chip selection data from the data to be parsed;

[0084] Step 2: Determine the physical interface chip to be configured based on the chip selection data;

[0085] Step 3: Send the configuration data to the physical interface chip to be configured based on the MDIO communication format.

[0086] As can be seen, this optional solution mainly describes how to transmit data when multiple chips are involved. In this optional solution, chip selection data is obtained from the data to be parsed; the configuration physical interface chip to be configured is determined based on the chip selection data; and the configuration data is sent to the configuration physical interface chip to be configured based on the MDIO communication format. In other words, this optional solution can select the corresponding chip from multiple chips based on the chip selection data and perform data transmission.

[0087] In summary, this embodiment first obtains the data to be parsed from the bus interface, then parses the data to be parsed based on the communication format corresponding to the bus interface to obtain the configuration data, and finally sends the configuration data to the physical interface chip based on the MDIO communication format to realize the corresponding software configuration, without having to connect an interface conversion module, thus improving the transmission efficiency. At the same time, it can also handle data transmitted from different buses, improving adaptability.

[0088] The following describes a method for configuring a physical interface chip provided in this application through another specific embodiment.

[0089] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the frame format of a method for configuring a physical interface chip provided in an embodiment of this application.

[0090] In this embodiment, the FPGA mainly parses the data from each interface and then configures the PHY chip through the MDIO interface based on the parsed data. Referring to the MDIO communication frame format, a single MDIO communication mainly transmits OP (operation code), PRTAD (PortAddress), DEVAD (device address), and ADDRESS / DATA data. Therefore, as long as the FPGA can correctly parse these data and then simulate the MDIO communication format to send the data to the PHY chip, the purpose of configuring the PHY chip can be achieved.

[0091] Please refer to Figure 3 , Figure 3 This is a schematic diagram of a method for configuring a physical interface chip provided in an embodiment of this application.

[0092] Therefore, in actual operation, the system of this embodiment can be divided into two parts: a data parsing module and a data processing module. The data parsing module is mainly used to parse the uplink transmitted data and pass it to the data processing module, or to receive data returned by the data processing module and convert it into corresponding communication frames to return to the uplink control terminal. The data processing module is mainly used to convert the data parsed by the data parsing module into MDIO frames and send them to the PHY chip, or to parse the data returned by the PHY chip and pass it to the data parsing module. The data processing module can identify the PHY chip that the current uplink control terminal needs to configure based on the parsed data, realizing the function of configuring multiple PHY chips on one control interface.

[0093] Based on the modules described above, this embodiment can implement the following steps, including:

[0094] Step 1: Obtain the data to be parsed from the bus interface;

[0095] Step 2: Parse the data to be parsed based on the communication format corresponding to the bus interface to obtain the configuration data;

[0096] Step 3: Send the configuration data to the physical interface chip based on the MDIO communication format so that the physical interface chip can perform software configuration based on the configuration data.

[0097] Step 4: In response to the read operation command, obtain the data to be read from the physical interface chip based on the MDIO communication format;

[0098] Step 5: Convert the data to be read into the corresponding communication frame based on the communication format of the bus corresponding to the read operation instruction;

[0099] Step 6: Send a communication frame through the bus corresponding to the read operation command.

[0100] As can be seen, the data to be parsed is first obtained from the bus interface, then the data is parsed according to the communication format corresponding to the bus interface to obtain the configuration data, and finally the configuration data is sent to the physical interface chip according to the MDIO communication format to realize the corresponding software configuration, without the need to connect the interface conversion module, which improves the transmission efficiency. At the same time, it can also handle data transmitted by different buses and improve adaptability.

[0101] The following section uses SPI as an example to explain in detail the working principle of the PHY chip configuration process:

[0102] Step 1: Redefine the SPI communication frame format according to the characteristics of MDIO communication. It can be divided into 28 bits of data: OP, PRTAD, DEVAD, and ADDRESS / DATA, which correspond to the operand, PHY address, device address, and communication data in MDIO communication, respectively.

[0103] Step 2: The FPGA parses the above data through the SPI parsing module and then passes it to the data selection module.

[0104] Step 3: The data selection module selects the corresponding data and passes it to the MDIO module based on the currently selected uplink interface (currently the SPI interface).

[0105] Step 4: The MDIO module sends the obtained data to the PHY chip according to the MDIO communication format to realize the PHY chip configuration function.

[0106] Step 5: If the current operation is a read operation, the MDIO module will return the obtained data to the corresponding parsing module via the data selection module.

[0107] Step 6: When defining the SPI communication frame format, an additional 4-bit data SEL can be defined to represent the PHY chip that needs to be configured. This allows different PHY chips to share the same PHY address and device address.

[0108] As can be seen, this embodiment solves the limitation of the original solution that can only configure the PHY chip through I2C, freeing up the I2C interface of a system device so that the PHY chip can be configured through other idle interfaces; at the same time, by redefining the frame format content, the function of multiple PHY chips sharing the same address can be realized.

[0109] As can be seen, this embodiment first obtains the data to be parsed from the bus interface, then parses the data to be parsed based on the communication format corresponding to the bus interface to obtain the configuration data, and finally sends the configuration data to the physical interface chip based on the MDIO communication format to realize the corresponding software configuration, without having to connect an interface conversion module, thus improving the transmission efficiency. At the same time, it can also handle data transmitted from different buses, improving adaptability.
