[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Please refer to Figure 1 , Figure 1 A flowchart of a method for configuring a field programmable gate array provided by an embodiment of the present invention. The method is applied to a server and may include:

[0054] Step 101: Obtain preset configuration flag information; wherein the preset configuration flag information includes flag information of configuration files corresponding to each preset media access control address; the preset media access control address includes the media access control address of the configured field programmable gate array.

[0055] It can be understood that the preset configuration flag information in this embodiment can be the flag information of the configuration file configured by each configured FPGA (field programmable gate array) that is pre-set and recorded; in this implementation example, the correspondence between the MAC (Media Access Control Address) address (i.e., the preset media access control address) of each configured FPGA and the corresponding preset configuration flag information can be pre-stored.

[0056] Correspondingly, the server in this embodiment can be used to manage the management server for configuring the FPGA, such as a server running a corresponding management platform. The specific method for the server to obtain the preset configuration flag information in this step can be set by the designer according to the practical scenario and user needs. For example, the server can read the stored preset configuration flag information. For example, the server can read the preset configuration flag information at a preset time interval to automatically upgrade the configuration of the configured FPGA.

[0057] Step 102: Detect whether there is a configuration file to be updated according to the preset configuration flag information; wherein the configuration file to be updated is a configuration file that needs to be updated corresponding to the preset configuration flag information.

[0058] It should be noted that the server in this embodiment can detect whether there is a configuration file that can be updated and upgraded by the FPGA (i.e., the configuration file to be updated), such as the latest configuration file, based on each preset configuration flag information, so as to use the configuration file to be updated to update the configuration of the corresponding FPGA.

[0059] Correspondingly, the specific method for the server in this step to detect whether there is a configuration file to be updated based on the preset configuration flag information can be set by the designer according to practical scenarios and user needs. For example, it can be implemented in the same or similar manner as the upgrade file detection method in the related art, and this embodiment does not impose any restrictions on this.

[0060] Step 103: If there is a configuration file to be updated, the configuration file to be updated is sent to the target field programmable gate array using a communication connection established based on the target network association address, so that the target field programmable gate array completes the configuration update using the received configuration file to be updated; wherein the target network association address includes the network association address bound to the preset media access control address corresponding to the configuration file to be updated.

[0061] It can be understood that the target FPGA in this step can be an FPGA that needs to be configured and updated using the corresponding configuration file to be updated; the target network association address in this step can be the IP (network association) address bound to the MAC address (i.e., the preset media access control address) of the target FPGA.

[0062] Since the management platform in the related art allocates IP addresses through the Dynamic Host Configuration Protocol (DHCP) each time a communication connection is established with the FPGA, the management platform will dynamically allocate IP addresses to the FPGA connected to the network according to the number and needs of devices in the network. When the FPGA is disconnected, reconnected, or subsequently upgraded, it is likely that a new IP address will need to be allocated to it to ensure the effective use of network resources, which will cause the FPGA to be unable to establish a communication connection with the server, and the server needs to repeatedly allocate IP addresses, which will not only cause a waste of communication resources, but also may cause the FPGA to be unable to be configured and updated in time. In this embodiment, by binding the MAC address (i.e., the preset media access control address) of the configured FPGA to the IP address used by the FPGA during configuration, it is not necessary to repeatedly allocate IP addresses during subsequent configuration updates and reconnections, thereby avoiding the waste of communication resources and increasing the rate of FPGA configuration updates.

[0063] Correspondingly, in order to ensure the accuracy of the configuration update of the target FPGA, the server in this embodiment can also detect the configuration update result of the target FPGA, so that when the configuration update fails, the corresponding configuration file to be updated can be resent to the target FPGA where the configuration update failed. For example, after step 103, the server can obtain the configuration feedback information sent by the current target FPGA through the current target IP address; wherein the current target FPGA is any target FPGA, and the current target IP address is the target IP address corresponding to the current target FPGA; when the configuration feedback information is configuration failure information, the corresponding configuration file to be updated is resent to the current target FPGA using the communication connection established based on the current target IP address; when the configuration feedback information is configuration success information, the preset configuration flag information corresponding to the current target FPGA is updated to the flag information of the corresponding configuration file to be updated.

[0064] Correspondingly, after obtaining the configuration feedback information sent by the current target FPGA through the current target IP address, the method further includes: detecting whether the configuration file flag information in the configuration feedback information is the same as the flag information of the corresponding configuration file to be updated; if they are the same, determining that the configuration feedback information is configuration success information, and the preset configuration flag information corresponding to the current target FPGA can be updated to the flag information of the corresponding configuration file to be updated; if they are not the same, determining that the configuration feedback information is configuration failure information, and the corresponding configuration file to be updated can be resent to the current target FPGA using the communication connection established based on the current target IP address.

[0065] Among them, the above-mentioned process of obtaining the configuration feedback information sent by the current target FPGA through the current target IP address may include: judging whether the configuration feedback information sent by the current target FPGA through the current target IP address is received within a preset detection time; if the configuration feedback information is received, the above-mentioned corresponding processing may be performed; if the configuration feedback information is not received, the MAC address of the current target FPGA may be directly unbound from the current target IP address, or it may be monitored whether a broadcast message (such as an IP address application request) sent by the current target FPGA is received within a preset reconnection time; wherein the broadcast message includes the MAC address of the current FPGA; if the broadcast message is not received, the MAC address of the current target FPGA is unbound from the current target IP address; if the broadcast message is received, the current target IP address is allocated to the current target FPGA, so that the current target FPGA can reuse the current target IP address to establish a communication connection with the server and obtain the corresponding configuration file to be updated.

[0066] It should be noted that the method provided in this embodiment can also be a process in which the server establishes a communication connection with each FPGA; such as the process in which the server establishes a communication connection with the FPGA when the FPGA is initially configured, for example, before step 101, it can also include: obtaining the MAC address in the IP address application request sent by the current FPGA through network broadcast; detecting whether the MAC address of the current FPGA is a recognized address (such as a MAC address in a preset format); if it is a recognized address, assigning the current IP address to the current FPGA, and establishing a communication connection with the current FPGA through the current IP. Among them, the current FPGA can be any FPGA.

[0067] Correspondingly, since the MAC address of the FPGA during the configuration process or after the configuration is completed (i.e., the preset MAC address) is bound to the corresponding IP address in this embodiment, the above process of assigning the current IP address to the current FPGA may include detecting whether the MAC address of the current FPGA is the preset MAC address; if it is the preset MAC address, assigning the IP address bound to the MAC address of the current FPGA to the current FPGA; if it is not the preset MAC address, assigning an IP address to the current FPGA through the Dynamic Host Configuration Protocol (DHCP), and binding the assigned IP address to the MAC address of the current FPGA.

[0068] Correspondingly, the server can also use the communication connection established based on the current IP address to send the configuration file corresponding to the current FPGA to the current FPGA, so that the current FPGA can complete the configuration using the received configuration file. Similar to the above-mentioned configuration update result determination process, after the server uses the communication connection established based on the current IP address to send the configuration file corresponding to the current FPGA to the current FPGA, it determines whether the initial configuration feedback information sent by the current FPGA through the current IP address is received within the preset detection time; wherein the current FPGA is any FPGA, and the current IP address is the IP address bound to the MAC address of the current FPGA; if the initial configuration feedback information is received, then when the initial configuration feedback information is configuration failure information, the configuration file corresponding to the current FPGA is resent to the current FPGA using the communication connection established based on the current IP address; when the initial configuration feedback information is configuration success information, the corresponding relationship between the MAC address of the current FPGA and the flag information of the configuration file corresponding to the current FPGA is recorded; if the initial configuration feedback information is not received, the MAC address of the current FPGA is unbound from the current IP address.

[0069] In other embodiments, before unbinding the MAC address of the current FPGA from the current IP address when the initial configuration feedback information is not received, it is also possible to monitor whether a broadcast message sent by the current FPGA is received within a preset reconnection time; wherein the broadcast message includes the MAC address of the current FPGA; if the broadcast message is not received, the step of unbinding the MAC address of the current FPGA from the current IP address is performed; if the broadcast message is received, the current IP address is assigned to the current FPGA, so that the current FPGA can use the current IP address to re-establish a communication connection with the server.

[0070] For example, the process of configuring the FPGA for the first time on a server can be as follows: Figure 2 As shown, the server follows Figure 3After the FPGA board is installed and powered on in the networking plan shown, each FPGA can establish a communication connection based on the IP address with the server; the server sends the configuration file of each FPGA through the network according to the assigned IP address, and continuously monitors the feedback message (i.e., initial feedback information) of the IP address within the preset detection time after the configuration file is sent; the FPGA that receives the configuration file is configured and determines whether the configuration is successful. If successful, the configuration success information is fed back through the assigned IP address, and if unsuccessful, the configuration failure information is fed back through the IP address; if the server monitors the feedback message of the IP address within the preset detection time, when the feedback message is configuration failure information, the configuration file is resent to the FPGA, and when the feedback message is configuration success information, an association relationship is established between the MAC address and the flag information (i.e., the preset configuration flag information) of the sent configuration file, so as to detect whether there is the latest configuration file (i.e., the configuration file to be updated) through the flag information of the configuration file. When the server detects that the MAC address has the latest configuration file, the latest configuration file is sent to the corresponding FPGA through the IP address bound to the MAC address to complete the configuration update of the FPGA.

[0071] Correspondingly, if the server does not detect the feedback message of the IP address within the preset detection time, it can detect whether the communication connection between the server and the FPGA is disconnected, such as Figure 4 As shown, if a broadcast message containing the MAC address is received within the preset reconnection time, such as a DHCP DISCOVER broadcast message, it can be determined that the communication connection between the server and the FPGA is disconnected, and the corresponding IP address can be matched by the MAC address of the FPGA and assigned to the FPGA; if a broadcast message containing the MAC address is still not received within the preset reconnection time, the IP address bound to the MAC address can be released so that the IP address can be reallocated later.

[0072] Correspondingly, the process of establishing a communication connection between each FPGA and the server based on the IP address can be as follows: Figure 5 As shown, the FPGA sends a DHCP DISCOVER broadcast message to the server through the network, and the broadcast message may include a vendor identifier and the MAC address of the FPGA; the server compares the MAC address and vendor identifier in the broadcast with the pre-stored MAC address format and identifier respectively. If the requirements are met, the server can mark the MAC address as an identified address, and allocate an IP address to the FPGA, and establish a communication connection between the FPGA and the server; wherein the MAC address is bound to the IP address.

[0073] Furthermore, in order to improve the utilization rate of IP addresses, the server in this embodiment can also detect the usage of the IP addresses bound to each preset MAC address; when an idle IP address whose unused time reaches the preset unbinding time is detected, the idle IP address is unbound from the corresponding preset MAC address to avoid wasting IP address resources. In other embodiments, the server can also communicate with the corresponding FPGA through the idle IP address when an idle IP address whose unused time reaches the preset unbinding time is detected; if the FPGA cannot be communicated with through a certain idle IP address, it can be considered that there is a problem with the FPGA, and the idle IP address can be unbound from the corresponding preset MAC address, and the alarm information of the FPGA can be output.

[0074] In this embodiment, the embodiment of the present invention detects whether there is a configuration file to be updated according to preset configuration flag information, and can automatically detect a new configuration file by using the flag information of the configuration files of each configured FPGA to update the configuration of the relevant FPGA, thereby realizing automatic configuration upgrade of the FPGA and improving user experience; and the server associates the MAC address of the FPGA with the IP address. When the FPGA is disconnected or reconnected, a new IP address does not need to be allocated for it, and the communication connection between the FPGA and the server can still be guaranteed, thereby realizing effective utilization of network resources.
