[0041] Based on a preset protocol, the current upgrade data packet is encapsulated to obtain a processed upgrade data packet; the preset protocol refers to the General Public Radio Interface Protocol.

[0042] The processed upgrade data packet is sent to the remote device;

[0043] Upon receiving the response data corresponding to the processed upgrade data packet returned by the remote device, the response data is sent to the host computer; the host computer is used to return the next upgrade data packet corresponding to the current upgrade data packet based on the response data;

[0044] The next upgrade data packet is used as the new current upgrade data packet, and the process jumps to the step of encapsulating the current upgrade data packet according to a preset protocol to obtain a processed upgrade data packet, until the next upgrade data packet is the last upgrade data packet of the target program; the remote device is used to perform program upgrade processing on the target program according to each received processed upgrade data packet to obtain the program upgrade result of the target program.

[0045] Fifthly, this application also provides a computer program product, including a computer program that, when executed by a processor, performs the following steps:

[0046] In response to a program upgrade request for a target program on a remote device sent by a host computer, the system receives a current upgrade data packet for the target program sent by the host computer; the distance between the remote device and the local device is greater than a preset distance; the target program refers to a field-programmable gate array (FPGA) program.

[0047] Based on a preset protocol, the current upgrade data packet is encapsulated to obtain a processed upgrade data packet; the preset protocol refers to the General Public Radio Interface Protocol.

[0048] The processed upgrade data packet is sent to the remote device;

[0049] Upon receiving the response data corresponding to the processed upgrade data packet returned by the remote device, the response data is sent to the host computer; the host computer is used to return the next upgrade data packet corresponding to the current upgrade data packet based on the response data;

[0050] The next upgrade data packet is used as the new current upgrade data packet, and the process jumps to the step of encapsulating the current upgrade data packet according to a preset protocol to obtain a processed upgrade data packet, until the next upgrade data packet is the last upgrade data packet of the target program; the remote device is used to perform program upgrade processing on the target program according to each received processed upgrade data packet to obtain the program upgrade result of the target program.

[0051] The aforementioned remote upgrade method, apparatus, computer equipment, storage medium, and computer program product for a field-programmable gate array (FPGA) program based on the Universal Public Radio Interface (UPRI) protocol first responds to a program upgrade request for a target program on a remote device sent by a host computer, receiving the current upgrade data packet of the target program sent by the host computer; the distance between the remote device and the local device is greater than a preset distance; the target program refers to an FPGA program; then, based on a preset protocol, the current upgrade data packet is format-encapsulated to obtain a processed upgrade data packet; the preset protocol refers to the UPR protocol; next, the processed upgrade data packet is sent to the remote device; then, upon receiving response data corresponding to the processed upgrade data packet returned by the remote device, the response data is sent to the host computer; the host computer is used to return the next upgrade data packet corresponding to the current upgrade data packet based on the response data; finally, the next upgrade data packet is used as the new current upgrade data packet, and the process jumps to the step of format-encapsulating the current upgrade data packet based on the preset protocol to obtain a processed upgrade data packet, until the next upgrade data packet is the last upgrade data packet of the target program; the remote device is used to perform program upgrade processing on the target program according to each received processed upgrade data packet to obtain the program upgrade result of the target program. In this way, during remote program upgrades, for long-distance transmission scenarios, the upgrade data packets sent by the host computer are encapsulated in a standardized format according to the common public radio interface protocol. Leveraging the protocol's standardized characteristics in long-distance, high-reliability wireless transmission, this avoids issues such as format corruption, data loss, or parsing errors during data packet transmission. A packet-by-packet confirmation mechanism is employed; after each encapsulated upgrade data packet is sent, the remote device must return the corresponding acknowledgment data before the next data packet transmission process is triggered. This mechanism accurately verifies whether each data packet is correctly received by the remote device. If a data packet transmission is abnormal, subsequent data packet transmission is suspended due to the lack of acknowledgment, preventing error accumulation and ensuring that all data packets are accurately received by the remote device and used for program upgrades. This improves the reliability and success rate of remote program upgrades. Furthermore, the entire process requires no manual intervention, avoiding the subjective factors and errors inherent in manual configuration and triggering methods that can lead to lower accuracy in remote program upgrades, further enhancing the accuracy of remote program upgrades.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0065] The remote programmable gate array (FPGA) program upgrade method based on the Common Public Radio Interface (CRI) protocol provided in this application can be applied to, for example... Figure 1 In the application environment shown, local device 102 communicates with host computer 101 via a network (network cable), and local device 102 also communicates with remote device 103 via fiber optic cable (fiber optic remote connection). For details, refer to...

Among them, host computer 101 can refer to a server that controls remote devices to perform remote program upgrades; local device 102 can refer to an embedded hardware device used for protocol conversion and data transmission of upgrade data packets; remote device 103 can refer to an embedded hardware device that performs remote program upgrades; the server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services.

[0066] In one exemplary embodiment, such as Figure 2 As shown, a method for remotely upgrading a field-programmable gate array (FPGA) based on a common public radio interface protocol is provided, which can be applied to... Figure 1 Taking a local device as an example, this embodiment of the method includes the following steps:

[0067] Step S201: In response to the program upgrade request for the target program of the remote device sent by the host computer, receive the current upgrade data packet of the target program sent by the host computer; the distance between the remote device and the local device is greater than a preset distance.

[0068] The target program, also known as the FPGA program, refers to the Field Programmable Gate Array program.

[0069] Among them, the program upgrade request refers to the request used to trigger the FPGA program upgrade process on the remote device.

[0070] The current upgrade data packet refers to a single transmission data packet segment sent by the host computer to the target program in batches. Because the target program (bitstream file) is large in size and cannot be sent in a single transmission, the host computer will split the complete target program into multiple data packets. The current upgrade data packet is the single packet data being processed in a certain transmission stage. It contains key information such as the packet sequence number, upgrade data body, and CRC (Cyclic Redundancy Check) check code. This information is used by the remote device to verify the integrity of the received data, reassemble the complete upgrade program in sequence, and finally realize the remote upgrade of the target program.

[0071] Here, distance refers to the actual communication link distance between the remote device and the local device.

[0072] The preset distance refers to a pre-set distance threshold, such as 1 kilometer.

[0073] For example, the local device monitors the communication link with the host computer in real time. When it detects a program upgrade request sent by the host computer for a target program on a remote device that is more than a preset distance away from the local device, it parses the key information carried in the program upgrade request, including the remote device identifier. Then, the local device matches the parsed remote device identifier with a pre-stored list of target remote devices. If the matching result indicates that the remote device identifier belongs to the list of target remote devices, the local device receives the current upgrade data packet of the target program sent by the host computer.

[0074] Step S202: Based on a preset protocol, the current upgrade data packet is format-encapsulated to obtain a processed upgrade data packet.

[0075] The default protocol, also known as the CPRI protocol, refers to the Common Public Radio Interface Protocol.

[0076] Among them, the processed upgrade data packet refers to the current upgrade data packet after format encapsulation processing.

[0077] For example, the local device queries the correspondence between the protocol and the encapsulation format based on the preset protocol to obtain the encapsulation format corresponding to the preset protocol, which is used as the encapsulation format corresponding to the current upgrade data packet; then, according to the encapsulation format corresponding to the current upgrade data packet, the current upgrade data packet is encapsulated to obtain the processed upgrade data packet.

[0078] Step S203: Send the processed upgrade data packet to the remote device.

[0079] For example, the local device performs status detection on the optical fiber link with the remote device to obtain optical power attenuation information, signal strength, and real-time bit error rate of the optical fiber link. Then, feature extraction processing is performed on the optical power attenuation information, signal strength, and real-time bit error rate to obtain a first feature vector of optical power attenuation information, a second feature vector of signal strength, and a third feature vector of real-time bit error rate. Then, the first feature vector, the second feature vector, and the third feature vector are concatenated to obtain a concatenated feature vector. Next, the concatenated feature vector is input into an optical fiber link status prediction model trained based on the random forest algorithm to obtain the predicted optical fiber link status. Then, if the predicted optical fiber link status is a preset optical fiber link status (such as a stable transmission status), the processed upgrade data packet is sent to the remote device through the optical fiber link.

[0080] Step S204: Upon receiving the response data corresponding to the processed upgrade data packet returned by the remote device, the response data is sent to the host computer; the host computer is used to return the next upgrade data packet corresponding to the current upgrade data packet based on the response data.

[0081] The response data represents the status feedback data returned by the remote device to the local device after receiving the processed upgrade data packet sent by the local device. It includes core fields such as the remote device identifier, the packet sequence number corresponding to the processed upgrade data packet, the CRC check result (success / failure) corresponding to the processed upgrade data packet, and the link status.

[0082] The next upgrade packet indicates the next data packet segment in the target program in response to the current upgrade packet. It should be noted that the target program (bitstream file) is split into multiple sequentially arranged upgrade packets. The sequence number of the next upgrade packet is the sequence number of the current upgrade packet plus 1, and its data body is the subsequent segment of the target program, which, together with the current upgrade packet, constitutes a complete target program data sequence.

[0083] For example, when the local device receives the response data corresponding to the processed upgrade data packet returned by the remote device, it parses the response data to obtain information such as the remote device identifier, the packet sequence number of the current processed upgrade data packet, and the CRC check result. The local device first matches the remote device identifier in the response data with the pre-stored target remote device list. If the matching result indicates that the remote device identifier belongs to the target remote device list, and the CRC check result indicates that the processed upgrade data packet has passed the check, the local device sends the response data to the host computer through the communication link with the host computer. The host computer retrieves the pre-stored target program (bit stream file) segment list based on the response data, extracts and returns the next upgrade data packet with the packet sequence number of the current packet sequence number plus 1.

[0084] Step S205: The next upgrade data packet is taken as the new current upgrade data packet, and the process jumps to the step of encapsulating the current upgrade data packet according to the preset protocol to obtain the processed upgrade data packet, until the next upgrade data packet is the last upgrade data packet of the target program; the remote device is used to perform program upgrade processing on the target program according to each received processed upgrade data packet to obtain the program upgrade result of the target program.

[0085] The program upgrade result refers to the final status feedback information output by the remote device after it has reassembled all the processed upgrade data packets received into a complete target program in sequence, and completed the program burning, verification and operation verification. This includes program upgrade success and program upgrade failure.

[0086] For example, the local device takes the next upgrade data packet as the new current upgrade data packet and jumps to the step of encapsulating the current upgrade data packet according to a preset protocol to obtain a processed upgrade data packet, until the next upgrade data packet is the last upgrade data packet of the target program; the remote device performs packet-by-packet verification on each received processed upgrade data packet, for example, comparing the packet sequence number of each processed upgrade data packet with a pre-stored list of data packet sequence numbers. If it is confirmed that the processed upgrade data packet is a valid segment in the sequence and there is no duplicate reception or sequence number gap, it splices the processed upgrade data packets in order according to their packet sequence numbers to obtain a spliced ​​upgrade data packet, which serves as the complete target program; then, the target program is written into the configuration storage unit of the FPGA for programming. After programming is completed, the remote device performs program initialization operations, restarts the FPGA configuration logic, loads the newly programmed target program, and performs a self-test on the core functional modules of the target program to obtain the self-test result of the target program, which serves as the program upgrade result of the target program.

[0087] In the aforementioned remote upgrade method for a field-programmable gate array (FPGA) program based on the Universal Public Radio Interface (UPRI) protocol, the system first responds to a program upgrade request sent by a host computer for the target program on a remote device by receiving the current upgrade data packet of the target program sent by the host computer. The distance between the remote device and the local device is greater than a preset distance. The target program refers to an FPGA program. Then, based on a preset protocol, the current upgrade data packet is format-encapsulated to obtain a processed upgrade data packet. The preset protocol refers to the UPR protocol. Next, the processed upgrade data packet is sent to the remote device. Then, upon receiving the response data corresponding to the processed upgrade data packet returned by the remote device, the response data is sent to the host computer. The host computer returns the next upgrade data packet corresponding to the current upgrade data packet based on the response data. Finally, the next upgrade data packet is used as the new current upgrade data packet, and the system jumps to the step of format-encapsulating the current upgrade data packet based on the preset protocol to obtain a processed upgrade data packet, until the next upgrade data packet is the last upgrade data packet of the target program. The remote device performs program upgrade processing on the target program according to each received processed upgrade data packet to obtain the program upgrade result of the target program. In this way, during remote program upgrades, for long-distance transmission scenarios, the upgrade data packets sent by the host computer are encapsulated in a standardized format according to the common public radio interface protocol. Leveraging the protocol's standardized characteristics in long-distance, high-reliability wireless transmission, this avoids issues such as format corruption, data loss, or parsing errors during data packet transmission. A packet-by-packet confirmation mechanism is employed; after each encapsulated upgrade data packet is sent, the remote device must return the corresponding acknowledgment data before the next data packet transmission process is triggered. This mechanism accurately verifies whether each data packet is correctly received by the remote device. If a data packet transmission is abnormal, subsequent data packet transmission is suspended due to the lack of acknowledgment, preventing error accumulation and ensuring that all data packets are accurately received by the remote device and used for program upgrades. This improves the reliability and success rate of remote program upgrades. Furthermore, the entire process requires no manual intervention, avoiding the subjective factors and errors inherent in manual configuration and triggering methods that can lead to lower accuracy in remote program upgrades, further enhancing the accuracy of remote program upgrades.

[0088] In an exemplary embodiment, step S202 above, based on a preset protocol, performs format encapsulation processing on the current upgrade data packet to obtain a processed upgrade data packet. Specifically, it includes the following: determining an initial data frame that matches the preset protocol; mapping the current upgrade data packet to a preset time slot in the initial data frame according to the frame format corresponding to the preset protocol to obtain an updated data frame; obtaining the frame header corresponding to the updated data frame, and combining the frame header with the updated data frame to obtain a processed upgrade data packet.

[0089] The initial data frame refers to a blank data frame structure that perfectly matches the preset protocol format requirements and serves as the carrier for the current upgrade data packet.

[0090] Among them, frame format refers to the unified specification of the initial data frame structure, field length, time slot division, synchronization identifier, etc. by the preset protocol.

[0091] Among them, the preset time slot refers to the dedicated time slot that is pre-specified in all time slots of the initial data frame to carry the current upgrade data packet.

[0092] The updated data frame refers to the complete data frame that carries the current upgrade data packet after mapping the current upgrade data packet to the preset time slot of the initial data frame.

[0093] The frame header refers to the control information segment attached to the header of the updated data frame based on a preset protocol. It includes key control fields such as frame synchronization identifier, frame sequence number, protocol version number, and time slot occupancy identifier.

[0094] For example, the local device queries the correspondence between the protocol and frame structure configuration parameters based on a preset protocol to obtain the frame structure configuration parameters corresponding to the preset protocol (including frame length, total number of time slots, time slot bandwidth, synchronization code position, etc.); then, according to the frame structure configuration parameters corresponding to the preset protocol, it generates an initial data frame that matches the preset protocol; then, it extracts the configuration information of the preset time slot (such as time slot number, time slot start position, time slot capacity) from the frame format corresponding to the preset protocol, and extracts the time slot capacity of the preset time slot from the configuration information of the preset time slot; then, it performs length adaptation processing on the current upgrade data packet to obtain the adapted current upgrade data packet; for example, if the data packet length of the current upgrade data packet is greater than the time slot capacity of the preset time slot, it is segmented according to the time slot bandwidth of the preset time slot to obtain the adapted current upgrade data packet; if the data packet length is less than... If the time slot capacity is within the preset time slot limit, then the end of the current upgrade data packet is padded with padding codes specified by the preset protocol to ensure that the data length is consistent with the preset time slot capacity, resulting in the adapted current upgrade data packet. If the data packet length is equal to the preset time slot capacity, the current upgrade data packet is used as the adapted current upgrade data packet. Then, according to the frame format corresponding to the preset protocol, the adapted current upgrade data packet is mapped to the preset time slot in the initial data frame, while the remaining non-preset time slots are kept in an idle code padded state, resulting in the updated data frame carrying upgrade data. Next, based on the frame header format requirements of the preset protocol, a frame header corresponding to the updated data frame is generated, and the frame header and the updated data frame are combined according to the frame structure order specified by the preset protocol (for example, the generated protocol-compliant frame header is appended to the header of the updated data frame) to obtain the processed upgrade data packet.

[0095] In this embodiment, by constructing a standardized data transmission carrier based on a preset protocol, the upgrade data packets are mapped to a dedicated time slot and combined with a protocol-compliant frame header, ensuring the compatibility of the upgrade data transmission with the preset protocol, avoiding conflicts with other service data in the link, significantly reducing the risk of data unpacking misalignment, and realizing efficient and orderly transmission of upgrade data packets in long-distance optical fiber links.

[0096] In an exemplary embodiment, step S201, before receiving the current upgrade data packet of the target program sent by the host computer in response to the program upgrade request for the target program of the remote device, specifically includes the following: receiving the program version query request for the target program of the remote device sent by the host computer, and sending the program version query request to the remote device, so that the remote device returns the program version information of the target program of the remote device according to the program version query request; sending the program version information to the host computer; the host computer is also used to return the program upgrade request for the target program of the remote device when it detects that the program version information is inconsistent with the preset program version information.

[0097] Among them, the program version query request refers to the request used to obtain the version status of the target program currently loaded on the remote device.

[0098] Among them, program version information refers to the version attribute data of the target program currently running on the remote device, such as the program version number of the target program on the remote device.

[0099] Among them, the preset program version information refers to the latest version attribute data of the target program pre-stored by the host computer, such as the latest program version number of the target program.

[0100] For example, the local device receives a program version query request for the target program of the remote device from the host computer via a communication link. If the remote device identifier in the program version query request is detected to exist in the pre-stored list of target remote devices, the local device sends the program version query request to the remote device via the fiber optic link. The remote device retrieves the program version information of the target program of the remote device stored in the local configuration unit according to the program version query request and returns the program version information to the local device. Then, the local device sends the program version information to the host computer. If the host computer detects that the program version information is inconsistent with the preset program version information, it returns a program upgrade request for the target program of the remote device. If the host computer detects that the program version information is consistent with the preset program version information, it determines that the current program of the remote device is the latest version and does not need to be upgraded. The host computer records the version comparison result and terminates the process.

[0101] In this embodiment, the pre-processed program version query and comparison mechanism enables accurate verification of the target program version status of remote devices, avoiding repeated upgrade processes for remote devices that have already loaded the latest version of the program. This significantly reduces the occupation of fiber optic link bandwidth and consumption of equipment resources by invalid data transmission, and improves the targeting and overall efficiency of program upgrades.

[0102] In an exemplary embodiment, the method further includes: if no response data corresponding to the processed upgrade data packet is received from the remote device, resending the processed upgrade data packet to the remote device.

[0103] For example, if the local device does not receive the response data corresponding to the processed upgrade data packet returned by the remote device, or if the CRC check result in the response data indicates that the processed upgrade data packet verification fails, the local device will retrieve the processed upgrade data packet that has not received a valid response data stored in the cache, and resend the processed upgrade data packet to the remote device according to the same link transmission rules and protocol format as the previous transmission.

[0104] In this embodiment, the retransmission mechanism of the upgraded data packets after processing can effectively cope with abnormal situations such as data packet loss and transmission timeout that may occur during long-distance fiber optic link transmission, avoid interruption of the upgrade process due to a single transmission failure, ensure the continuity and reliability of the target program's batch upgrade process, and improve the success rate of remote device program upgrades.

[0105] In an exemplary embodiment, the method further includes: obtaining the number of retransmissions corresponding to the processed upgrade data packet; generating program upgrade failure information corresponding to the target program if the number of retransmissions exceeds the preset number of retransmissions; and sending the program upgrade failure information to the host computer.

[0106] The number of retransmissions refers to the cumulative number of times the local device performs repeated retransmission operations for the processed upgrade data packet.

[0107] The preset resend count refers to the number of resends set in advance. It should be noted that the preset resend count depends on the situation.

[0108] Among them, the program upgrade failure information refers to the abnormal status feedback data generated by the local device for the target program, which includes the device identifier of the remote device, the packet sequence number of the processed upgrade data packet, the number of resends, and other information.

[0109] For example, the local device extracts the retransmission count corresponding to the processed upgrade data packet from the retransmission count statistics cache table; then, it judges the retransmission count based on the preset retransmission count; if the retransmission count is greater than the preset retransmission count, it combines the device identifier of the remote device, the packet sequence number of the processed upgrade data packet, and the retransmission count to obtain the program upgrade failure information corresponding to the target program; then, it sends the program upgrade failure information to the host computer through the communication link with the host computer.

[0110] It should be noted that the preset number of retransmissions can be determined as follows: obtain the historical packet loss rate and transmission delay time of the fiber optic link with the remote device, extract the feature vectors of the historical packet loss rate and the transmission delay time, and concatenate the feature vectors of the historical packet loss rate and the transmission delay time to obtain the concatenated feature vector; then, input the concatenated feature vector into the trained retransmission number prediction model to obtain the predicted number of retransmissions for the fiber optic link, which is used as the preset number of retransmissions.

[0111] In this embodiment, by setting a threshold for the number of retransmissions and determining if the limit is exceeded, the unlimited retransmission of the same processed upgrade data packet can be avoided, reducing invalid link occupation and device computing resource consumption. This provides an accurate basis for subsequent fault diagnosis, link optimization, or upgrade process retry, ensuring the controllability of the upgrade process and operational efficiency.

[0112] In one exemplary embodiment, the local device has a built-in first high-speed serial transceiver interface, and the remote device has a built-in second high-speed serial transceiver interface; the first high-speed serial transceiver interface and the second high-speed serial transceiver interface are connected by optical fiber.

[0113] Therefore, step S203 above, which involves sending the processed upgrade data packet to the remote device, specifically includes the following: sending the processed upgrade data packet to the remote device through the first high-speed serial transceiver interface and the second high-speed serial transceiver interface.

[0114] The first high-speed serial transceiver interface refers to the high-speed serial transceiver interface built into the local device.

[0115] The high-speed serial transceiver interface is also known as the GT (Gigabit Transceiver) interface.

[0116] The second high-speed serial transceiver interface refers to the high-speed serial transceiver interface built into the remote device.

[0117] For example, the local device transmits the processed upgrade data packet to the serial-to-parallel conversion module of the first high-speed serial transceiver interface. The serial-to-parallel conversion module converts the processed upgrade data packet into a high-speed serial data stream according to a preset serialization clock frequency. Then, the high-speed serial data stream is encoded by the encoding module of the first high-speed serial transceiver interface, and the encoded electrical signal serial data stream is converted into an optical signal. It is injected into the optical fiber link according to a preset optical power threshold (such as -3dBm~0dBm), so that the optical signal is transmitted over a long distance through the optical fiber to the remote device. The optical signal transmitted through the optical fiber is restored to an electrical signal serial data stream by the photoelectric conversion module of the second high-speed serial transceiver interface of the remote device. Then, the electrical signal serial data stream is decoded by the decoding module to obtain a serial data frame. Finally, the serial data is converted into a parallel format processed upgrade data packet by the parallel-to-serial conversion module.

[0118] In this embodiment, a direct fiber optic connection architecture between the first high-speed serial transceiver interface and the second high-speed serial transceiver interface enables high-speed, low-latency, and interference-resistant transmission of the processed upgrade data packets. This avoids the bandwidth contention problem of traditional Ethernet and other shared links, ensuring the timeliness and stability of upgrade data transmission.

[0119] In one exemplary embodiment, such as Figure 3 As shown, another method for remotely upgrading field-programmable gate arrays (FPGAs) based on the Common Public Radio Interface (CPI) protocol is provided, which can be applied to... Figure 1 Taking a local device as an example, the specific steps include:

[0120] Step S301: Receive the program version query request for the target program of the remote device sent by the host computer, and send the program version query request to the remote device so that the remote device returns the program version information of the target program of the remote device according to the program version query request.

[0121] Step S302: Send the program version information to the host computer; the host computer is also used to return a program upgrade request for the target program on the remote device when it detects that the program version information is inconsistent with the preset program version information.

[0122] Step S303: In response to the program upgrade request for the target program of the remote device sent by the host computer, receive the current upgrade data packet of the target program sent by the host computer; the distance between the remote device and the local device is greater than a preset distance; the target program refers to a field-programmable gate array program.

[0123] Step S304: Determine the initial data frame that matches the preset protocol; the preset protocol refers to the General Public Radio Interface Protocol.

[0124] Step S305: According to the frame format corresponding to the preset protocol, the current upgrade data packet is mapped to the preset time slot in the initial data frame to obtain the updated data frame.

[0125] Step S306: Obtain the frame header corresponding to the updated data frame, and combine the frame header with the updated data frame to obtain the processed upgrade data packet.

[0126] Step S307: Send the processed upgrade data packet to the remote device.

[0127] Step S308: Upon receiving the response data corresponding to the processed upgrade data packet returned by the remote device, the response data is sent to the host computer; the host computer is used to return the next upgrade data packet corresponding to the current upgrade data packet based on the response data.

[0128] Step S309: The next upgrade data packet is taken as the new current upgrade data packet, and the process jumps to the step of encapsulating the current upgrade data packet according to the preset protocol to obtain the processed upgrade data packet, until the next upgrade data packet is the last upgrade data packet of the target program; the remote device is used to perform program upgrade processing on the target program according to each received processed upgrade data packet to obtain the program upgrade result of the target program.

[0129] In the aforementioned remote programmable gate array (FPGA) program upgrade method based on the Common Public Radio Interface (CRI) protocol, during remote program upgrades, for long-distance transmission scenarios, the upgrade data packets sent by the host computer are encapsulated in a standardized format according to the CRI protocol. Leveraging the protocol's standardized characteristics in long-distance, high-reliability wireless transmission, this method avoids issues such as format corruption, data loss, or parsing errors during data packet transmission. A packet-by-packet confirmation mechanism is employed; after each encapsulated upgrade data packet is sent, the system waits for the remote device to return the corresponding acknowledgment data before triggering the transmission of the next data packet. This mechanism accurately verifies whether each data packet is correctly received by the remote device. If a data packet transmission is abnormal, subsequent data packet transmission is suspended due to the lack of acknowledgment, preventing error accumulation and ensuring that all data packets are accurately received by the remote device for program upgrades. This improves the reliability and success rate of remote program upgrades. Furthermore, the entire process requires no manual intervention, avoiding the subjective factors and errors inherent in manual configuration and triggering methods that can lead to lower accuracy in remote program upgrades. This further enhances the accuracy of remote program upgrades.

[0130] In an exemplary embodiment, to more clearly illustrate the remote upgrade method for field-programmable gate arrays (FPGAs) based on the Common Public Radio Interface (CPRI) protocol provided in this application, the following specific embodiment will be used to describe this method in detail. In one embodiment, this application also provides a remote FPGA upgrade method based on the CPRI protocol. Specifically, it includes the following:

[0131] The entire remote upgrade system comprises three main components: a host computer, a local server rack, and remote network-connected equipment. The host computer is connected to the FPGA board in the local server rack via a network cable, and the FPGA board in the local server rack is connected to the FPGA board to be upgraded in the remote network-connected equipment via fiber optic cable. The specific connection relationships are as follows: Figure 4 As shown, both the local FPGA and the remote FPGA need to be chips with GT interfaces. Each FPGA at both ends contains 4 GT interfaces, which can be used for fiber optic remote connections.

[0132] First step: Arrange the above three main entities according to... Figure 4 Once the connection is established, all devices are powered on.

[0133] The host computer runs the console software, which is responsible for querying and obtaining the working status of the local cabinet and remote devices, judging the format of the FPGA target file to be upgraded, splitting and reassembling packets, adding CRC checks, and sending and receiving data packets.

[0134] The FPGA board in the local cabinet acts as a bidirectional gateway, requiring it to handle data flows in both directions simultaneously.

[0135] For the host computer, it needs to parse various commands from the host computer, including query and upgrade commands. At the same time, after receiving the relevant commands, it should respond to the host computer immediately and ensure smooth communication through a handshake mechanism. In addition, the local FPGA needs to frame the received upgrade data packets according to the CPRI protocol and send them to the remote device.

[0136] For remote devices, it needs to feed back information such as the working status and version of the remote device to the host computer, as well as transparently transmit normal business data of the remote device.

[0137] The remote device's FPGA performs the following functions: extracts upgrade data from CPRI frames and stores it in the receive buffer. After receiving and verifying a data packet, it initiates the Flash write process. Using MultiBoot technology, the upgrade file is written to the specified address of the Flash (the storage address of the updated image) via the SPI (Serial Peripheral Interface) interface.

[0138] Specific functions are as follows Figure 5 As shown.

[0139] Step 2: Connect to the local FPGA via the host computer console. Once successful, proceed to the upgrade steps.

[0140] Step 3: Check the remote FPGA version to confirm the correctness of the target file to be upgraded;

[0141] Step 4: Select the target file to be upgraded, click Upgrade, and the flowchart of the host computer upgrade control is as follows. Figure 6 As shown;

[0142] After sending the upgrade command, the host computer confirms that the remote FPGA is ready and then begins sending data packets in segments. Each time a data packet is sent, a corresponding acknowledgment is received before sending the next packet, continuing until all packets are sent. If no acknowledgment is received midway, retransmission is initiated. If no acknowledgment is received after a certain number of retransmissions, the upgrade fails.

[0143] At this time, after receiving the data packet, the local FPGA maps the data packet buffered in the FIFO (First In First Out) to the third time slot according to the frame format of the CPRI protocol and sends it to the remote FPGA. At the same time, it receives the status data fed back by the remote FPGA in the fourth time slot.

[0144] After receiving the upgrade command, the remote FPGA first erases the fixed address segment of the Flash memory. Upon completion, it sends an ACK (Acknowledgement) signal prepared by the host computer. Corresponding to the local FPGA's CPRI protocol frame, the remote FPGA receives and buffers data in the third time slot of the CPRI protocol frame. After receiving a complete data packet, it performs a CRC check. If the CRC check passes, it buffers the next received data into another FIFO using a ping-pong method. Simultaneously, it sends a CRC check success acknowledgment signal in the fourth time slot of the CPRI protocol frame. Furthermore, the FPGA writes the correctly verified data to the fixed address 0x10000000 in the Flash memory via SPI.

[0145] The CPRI protocol transmit and receive frame formats for the two FPGAs are as follows: Figure 7 , Figure 8 As shown;

[0146] Step 5: After the upgrade is complete, power on the remote device again and check the upgraded FPGA version information on the host computer to confirm whether the upgrade was successful.

[0147] This solution, based on the CPRI protocol, sends upgrade data packets to remote network-connected devices via fiber optic cable. Simultaneously, it upgrades FPGAs using the Multiboot method, enabling secure and reliable FPGA upgrades at the kilometer level. This reduces FPGA failures caused by transmission failures and eliminates the hassle of on-site FPGA upgrades.

[0148] In the above embodiments, during remote program upgrades, for long-distance transmission scenarios, the upgrade data packets sent by the host computer are encapsulated in a standardized format according to the Common Public Radio Interface Protocol (CPR). Leveraging the protocol's standardized characteristics in long-distance, high-reliability wireless transmission, this avoids issues such as format corruption, data loss, or parsing errors during data packet transmission. A packet-by-packet confirmation mechanism is employed; after each encapsulated upgrade data packet is sent, the remote device must return the corresponding acknowledgment data before the next data packet transmission process is triggered. This mechanism accurately verifies whether each data packet is correctly received by the remote device. If a data packet transmission is abnormal, subsequent data packet transmission is suspended due to the lack of acknowledgment, preventing error accumulation and ensuring that all data packets are accurately received by the remote device for program upgrades. This improves the reliability and success rate of remote program upgrades. Furthermore, the entire process requires no manual intervention, avoiding the subjective factors and errors inherent in manual configuration and triggering methods, which can lead to lower accuracy in remote program upgrades. This further enhances the accuracy of remote program upgrades. Meanwhile, the remote network-connected equipment and the local equipment are connected via optical fiber, and the FPGAs communicate with each other via a high-speed serial interface based on the CPRI protocol. Under the premise of establishing an optical fiber link, upgrade data packets are sent in the user's time slot, which ensures the success rate of long-distance transmission of upgrade data packets. In the case of the remote FPGA adopting the Multiboot upgrade method, the risk of FPGA long-distance upgrade failure is ultimately avoided.

[0149] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.

These steps or stages are not necessarily completed at the same time, but can be executed at different times.
