[0040] The core of this invention is to provide a method for obtaining the accelerator card address and related components, which can automatically identify the MAC address of the accelerator card, making it easier for users to configure the accelerator card subsequently.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Figure 1 A flowchart of a method for obtaining an accelerator card address provided by the present invention, the method comprising:

[0043] S11: When the accelerator card is connected to the host, configure the corresponding PCIE (peripheral component interconnect express, high-speed serial computer expansion bus standard) parameters for the accelerator card;

[0044] In establishing a network communication connection between an FPGA (Field Programmable Gate Array) accelerator card and a host server, a crucial prerequisite before configuring the FPGA accelerator card's MAC (Media Access Control) address is knowing its MAC address. Since FPGA accelerator cards are frequently circulated among engineers, their MAC addresses are often not marked on their surfaces, and they are rarely properly registered for future use. Because the MAC address of an FPGA accelerator card cannot be directly obtained through network configuration commands, acquiring the MAC address before use is extremely important.

[0045] This application configures the corresponding PCIe parameters for the accelerator card when it is connected to the host. Only after configuring the PCIe parameters can the MAC address of the accelerator card be obtained.

[0046] S12: Read the MAC address of the accelerator card through PCIe parameters;

[0047] The MAC address of the accelerator card can only be read after configuring the PCIe parameters. Specifically, the program can only be burned to the accelerator card after configuring the PCIe parameters, and then the MAC address of the accelerator card can be obtained.

[0048] S13: Save the MAC address to the preset storage space.

[0049] After obtaining the MAC address, save it to the preset storage space so that the host can retrieve the MAC address from the storage space for subsequent configuration.

[0050] This application provides a method for obtaining the address of an accelerator card, applied in the computer field. When the accelerator card is connected to a host, corresponding PCIe parameters are configured for the accelerator card; the MAC address of the accelerator card is read through the PCIe parameters; and the MAC address is saved to a preset storage space. Configuring the corresponding PCIe parameters for the accelerator card when it is connected to the host is necessary to read the accelerator card's MAC address. After reading the MAC address, it is saved to the preset storage space for later retrieval. This application can automatically identify the MAC address of the accelerator card, facilitating subsequent configuration by the user.

[0051] Based on the above embodiments:

[0052] Figure 2 This invention provides a schematic diagram of an accelerator card connection structure;

[0053] In a preferred embodiment, when the accelerator card is connected to the host, the corresponding PCIe parameters are configured for the accelerator card, including:

[0054] When the accelerator card is connected to the first optical module, optical fiber, second optical module and network card in sequence, and the accelerator card and network card are connected to the host respectively, configure the corresponding PCIe parameters for the accelerator card.

[0055] The first optical module, the second optical module, and the optical fiber are used to provide a network for the accelerator card.

[0056] Considering that the accelerator card needs to be connected to the network to operate, the accelerator card is connected to the first optical module, the first optical module is connected to the second optical module through an optical fiber, the second optical module is connected to the network card, and the accelerator card can connect to the network when the network card is connected to the host.

[0057] Once the hardware environment for the accelerator card is set up, it can achieve network connectivity in order to obtain the MAC address later.

[0058] As a preferred embodiment, the corresponding PCIe parameters are configured for the accelerator card, including:

[0059] Identify the type of accelerator card;

[0060] The corresponding PCIe parameters for each type of accelerator card are determined based on the pre-stored correspondence between the accelerator card type and PCIe parameters.

[0061] Given that there are many types of accelerator cards, and each accelerator card has its corresponding PCIe parameters, it is necessary to identify the type of accelerator card in advance in order to configure the corresponding PCIe parameters for the accelerator card.

[0062] The program can only be burned to the accelerator card by configuring the corresponding PCIe parameters.

[0063] In addition, the path location and environment variables need to be configured.

[0064] As a preferred embodiment, before reading the accelerator card's MAC address via PCIe parameters, the following steps are also included:

[0065] Determine whether the accelerator card is identified through PCIe parameters;

[0066] If the accelerator card is detected, proceed to the step of reading the accelerator card's MAC address through PCIe parameters;

[0067] If the accelerator card is not detected, return to the steps for configuring the corresponding PCIe parameters for the accelerator card.

[0068] If the accelerator card is successfully identified through the PCIe parameters, it proves that the PCIe parameters have been configured successfully, and the next step of reading the MAC address can be performed. If the accelerator card is not identified, it may be due to a failure in parameter configuration, which prevents the accelerator card from being identified. Therefore, the PCIe parameters need to be reconfigured.

[0069] As a preferred embodiment, reading the MAC address of the accelerator card via PCIe parameters includes:

[0070] The data in the register that stores the MAC address in the accelerator card is read using the PCIe parameters.

[0071] The accelerator card has a corresponding location that stores its MAC address. Specifically, the MAC address of the accelerator card is stored in the register of the accelerator card. Therefore, the MAC address of the accelerator card can be obtained by reading the register at the corresponding location.

[0072] In a preferred embodiment, the register includes a first preset position and a second preset position;

[0073] Data is read from the register storing the MAC address in the accelerator card via PCIe parameters, including:

[0074] The high and low bits of the MAC address are read from the first and second preset positions respectively using the PCIe parameters.

[0075] The MAC address is obtained by combining the high-order address and the low-order address.

[0076] Considering that the accelerator card stores the MAC address in two parts, high and low, it will read from the register that stores the high part and the register that stores the low part respectively during the reading process.

[0077] Figure 3 This is a flowchart illustrating the program implementation for reading addresses using an accelerator card, as provided by the present invention.

[0078] The address read from bit 0x30038 is 0x9791D2ED, and the address read from bit 0x3003C is 0xFAFA, so the MAC address of this register is 0xFAFA9791D2ED.

[0080] Configuration unit 41 is used to configure the corresponding PCIe parameters for the accelerator card when the accelerator card is connected to the host.

[0081] Reading unit 42 is used to read the MAC address of the accelerator card through PCIe parameters;

[0082] The storage unit 43 is used to save the MAC address to a preset storage space.

[0083] Specifically, configuration unit 41 is used to configure corresponding PCIE parameters for the accelerator card when the accelerator card is connected to the first optical module, optical fiber, second optical module and network card in sequence, and when the accelerator card and network card are connected to the host respectively.

[0084] The first optical module, the second optical module, and the optical fiber are used to provide a network for the accelerator card.

[0085] Identify the type of accelerator card;

[0086] The corresponding PCIe parameters for each type of accelerator card are determined based on the pre-stored correspondence between the accelerator card type and PCIe parameters.

[0087] It also includes a judgment unit to determine whether the accelerator card is identified through PCIe parameters;

[0088] If the accelerator card is detected, proceed to the step of reading the accelerator card's MAC address through PCIe parameters;

[0089] If the accelerator card is not detected, return to the steps for configuring the corresponding PCIe parameters for the accelerator card.

[0090] The reading unit 42 is specifically used to read data from the register that stores the MAC address in the accelerator card through PCIE parameters.

[0091] The register includes a first preset position and a second preset position;

[0092] Data is read from the register storing the MAC address in the accelerator card via PCIe parameters, including:

[0093] The high and low bits of the MAC address are read from the first and second preset positions respectively using the PCIe parameters.

[0094] The MAC address is obtained by combining the high-order address and the low-order address.
