[0035] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

[0036] The specific implementation of the embodiment of the present application is further explained below in conjunction with the accompanying drawings of the embodiment of the present application.

[0037] The embodiment of the present application provides a data transmission method based on a DPU, which is applied to an arbitration unit of a DPU, such as Figure 1 As shown, it is a schematic diagram of a DPU structure provided in an embodiment of the present application. The DPU in the embodiment of the present application includes an arbitration unit, a cache unit, a media access control unit and a communication main line, wherein one end of the arbitration unit is connected to the media access unit and the cache unit respectively, and the other end is connected to the communication main line. Furthermore, the DPU is connected to the CPU through the communication main line.

[0038] Furthermore, the DPU-based data transmission method of the embodiment of the present application comprises the following specific steps: Figure 2 As shown, including:

[0039] S201, if the arbitration unit receives a transaction quotation data packet, the arbitration unit transmits the transaction quotation data packet to the CPU via the communication main line.

[0040] In an embodiment of the present application, when the market server sends a transaction market data packet to the DPU, the DPU receives the transaction market data packet through the media access control unit. After receiving the transaction market data packet, the media access controller sends the transaction market data packet to the arbitration unit. After receiving the transaction market data packet, the arbitration unit transmits the transaction market data packet to the CPU through the communication main line to ensure low-latency transmission of the transaction market data packet.

[0041] S202, when the transaction quotation data packet transmission is completed, the arbitration unit transmits the log data stored in the cache unit to the CPU through the communication main line.

[0042] In the embodiment of the present application, when the arbitration unit transmits the transaction quotation data packet to the CPU through the communication main line, the DPU collects its own operation data, operation status data and other log data, and temporarily writes the log data into the cache unit inside the DPU. When the arbitration unit determines that the transmission of the transaction quotation data packet is completed, the arbitration unit reads the log data in the cache unit and transmits the log data to the CPU through the communication main line, thereby avoiding transmission competition between the log data and the transaction quotation data packet.

[0043] According to the DPU-based data transmission method provided in the embodiment of the present application, after receiving the transaction market data packet, the arbitration unit transmits the transaction market data packet to the CPU through the communication main line, so that the transaction market data packet can monopolize the communication main line, and then the transaction market data packet can be transmitted to the CPU with low latency. Furthermore, when the transmission of the transaction market data packet is completed, the arbitration unit transmits the log data stored in the cache unit to the CPU, which can avoid transmission competition between the log data and the transaction market data packet, and further ensure the low-latency transmission of the transaction market data packet to the CPU.

[0044] Furthermore, the DPU-based data transmission method of the embodiment of the present application may further include the following steps:

[0045] S203: If the arbitration unit does not receive the transaction quotation data packet and the cache unit stores the log data, the log data is transmitted to the CPU via the communication main line.

[0046] In an embodiment of the present application, when the arbitration unit does not receive a transaction quotation data packet, the arbitration unit determines that the transaction quotation data packet does not need to be transmitted at this time, and further determines that the transmission of the log data at this time will not compete with the transmission of the transaction quotation data packet. The arbitration unit determines whether the log data exists in the cache unit, and when it is determined that the log data exists in the cache unit, the arbitration unit transmits the log data to the CPU to complete the transmission of the log data.

[0047] Furthermore, when the transaction quotation data packet is transmitted, the embodiment of the present application transmits the log data of the cache unit to the CPU through the communication main line, which may include the following steps:

[0048] S2021, the arbitration unit reads the log data packet in the cache unit.

[0049] In the embodiment of the present application, the arbitration unit reads the log data packet in the cache unit during the process of transmitting the log data to the CPU via the communication main line. Specifically, when the DPU of the embodiment of the present application writes the log data to the cache unit, it obtains a preset number of bytes, and divides the log data into a plurality of log sub-data using the preset number of bytes, and further, encapsulates each log sub-data to generate a plurality of log data packets, and finally writes the log data to the cache unit in the form of the log data packet, so that the log data in the cache unit is stored in the form of a plurality of log data packets.

[0050] S2022: The arbitration unit sends the log data packet to the CPU through the communication main line.

[0051] In the embodiment of the present application, after the arbitration unit completes reading the log data packet, the arbitration unit sends the read log data packet to the CPU through the communication main line to transmit the log data to the CPU.

[0052] The embodiment of the present application can conveniently transmit log data by dividing log data into log data packets for transmission.

[0053] Furthermore, if Figure 3 As shown, an embodiment of the present application provides another DPU structure schematic diagram, wherein the cache unit of the embodiment of the present application includes a first cache unit and a second cache unit connected to each other, and the storage capacity of the first cache unit is smaller than the storage capacity of the second storage unit. Specifically, one end of the first cache unit is connected to the arbitration unit, and the other end is connected to the second storage unit.

[0054] Furthermore, the reading of the log data packet in the cache unit in the embodiment of the present application may include the following steps:

[0055] S20211, the arbitration unit reads the log data packet in the first cache unit.

[0056] In an embodiment of the present application, when the arbitration unit transmits the log data packet, the log data packet is read in the first cache unit, and further, the arbitration unit transmits the log data packet to the CPU via the communication main line. Specifically, the log data packet of the first cache unit is read in the second cache unit by the first cache unit when the log data is transmitted. Further, when the DPU writes the log data packet to the cache unit, the DPU writes the log data packet to the second cache unit, and when the log data packet needs to be transmitted, the first cache unit reads the log data packet in the second cache unit.

[0057] Furthermore, in the first cache unit, after the arbitration unit completes reading the log data packet, the first cache unit retains the log data packet, and when the arbitration unit completes transmitting the log data packet, the first cache unit deletes the log data packet.

[0058] Furthermore, after the second cache unit reads the log data packet, the second cache unit deletes the read log data packet.

[0059] The embodiment of the present application stores log data through a cache unit, which can avoid competition between the transmission of log data and the transmission of market trading data packets. By setting up two cache units, the transmitted log data packets can be temporarily retained during the transmission of the log data packets, and then the log data packets can be deleted when the transmission of the log data packets is completed. Deleting the log data packets can ensure that the log data packets are completely transmitted to the CPU, thereby ensuring the completeness of the log data transmission.

[0060] Furthermore, the DPU-based data transmission method of the embodiment of the present application may further include the following steps:

[0061] S204, if the arbitration unit receives a transaction quotation data packet during the process of transmitting the log data packet to the CPU via the communication main line, the arbitration unit stops transmitting the log data packet and transmits the transaction quotation data packet via the communication main line.

[0062] In an embodiment of the present application, when the arbitration unit is transmitting a log data packet to the CPU via the communication main line, if the arbitration unit receives a transaction quotation data packet sent by the media access control unit, the arbitration unit determines that the transaction quotation data packet needs to be transmitted at this time, and then the arbitration unit immediately stops transmitting the log data packet and transmits the transaction quotation data packet to the CPU via the communication main line.

[0063] In the process of transmitting the log data packet to the CPU via the communication main line, if the arbitration unit receives the transaction market data packet sent by the media access control unit, the transaction market data packet can be transmitted to the CPU in a timely manner by immediately stopping the transmission of the log data packet and transmitting the transaction market data packet to the CPU via the communication main line.

[0064] Furthermore, the DPU-based data transmission method of the embodiment of the present application may further include the following steps:

[0065] The DPU-based data transmission method of this embodiment can be executed by any appropriate electronic device with data processing capabilities, including but not limited to: servers, mobile terminals (such as mobile phones, PADs, etc.) and PCs, etc.

[0066] S205 , if the transmission of the log data packet is stopped during the transmission of the log data packet, the arbitration unit detects whether there is a first log data packet being transmitted.

[0067] In the embodiment of the present application, when the arbitration unit stops transmitting the log data packet during the process of transmitting the log data packet, the arbitration unit simultaneously detects whether there is a first log data packet being transmitted at this time.

[0068] S206: If yes, the arbitration unit sends a retain instruction to the first cache unit and adds an error mark to the first log data packet.

[0069] In an embodiment of the present application, after the arbitration unit determines to store the first log data packet, the arbitration unit sends a retention instruction to the first cache unit to instruct the first cache unit to save the first data packet, and adds an error mark to the first log data packet to instruct the CPU to delete the first log data packet.

[0070] S207, when the transaction quotation data packet is transmitted, the arbitration unit obtains the first log data packet in the first cache unit, and transmits the first log data packet to the CPU through the communication main line.

[0071] In an embodiment of the present application, when the arbitration unit completes transmission of the newly received transaction quotation data packet, the arbitration unit re-reads the first log data packet in the first cache unit, and re-transmits the first log data packet to the CPU through the communication main line, thereby ensuring that the log data packets that the CPU can receive are all complete.

[0072] In the embodiment of the present application, after the arbitration unit determines that the first data packet exists, it sends a retention instruction to the first cache unit to instruct the first cache unit to save the first data packet, and adds an error mark in the first log data packet to instruct the CPU to delete the first log data packet. When the transmission of the newly received transaction quotation data packet is completed, the arbitration unit re-reads the first log data packet in the first cache unit, and re-transmits the first log data packet to the CPU through the communication main line, thereby ensuring the integrity of the log data transmission.

[0073] Furthermore, the embodiment of the present application provides another data transmission method based on DPU, the specific steps are as follows: Figure 4 Shown include:

[0074] If the arbitration unit receives a transaction quotation data packet, it transmits the transaction quotation data packet to the CPU through the communication main line. In the process of transmitting the transaction quotation data packet to the CPU through the communication main line, the DPU collects its own operation data, operation status data and other log data, and obtains a preset number of bytes at the same time, and uses the preset number of bytes to divide the log data into multiple log sub-data. Further, each log sub-data is encapsulated to generate multiple log data packets, and finally the log data is written into the second cache unit in the form of a log data packet.

[0075] When transmitting the log data packet, the arbitration unit reads the log data packet in the first cache unit to transmit the log data packet to the CPU through the communication main line. When the arbitration unit transmits the log data packet to the CPU through the communication main line, if the arbitration unit receives the transaction market data packet sent by the media access control unit, the transaction market data packet is transmitted to the CPU through the communication main line.

[0076] When the arbitration unit stops transmitting the log data packet during the process of transmitting the log data packet, the arbitration unit simultaneously detects whether there is a first log data packet being transmitted at this time. If so, the arbitration unit sends a retention instruction to the first cache unit to instruct the first cache unit to save the first data packet, and adds an error mark in the first log data packet to instruct the CPU to delete the first log data packet. When the arbitration unit completes the transmission of the received transaction quotation data packet, the arbitration unit re-reads the first log data packet in the first cache unit, and re-transmits the first log data packet to the CPU through the communication main line.

[0077] Furthermore, the embodiment of the present application provides a data transmission device based on a DPU, which is applied to an arbitration unit of the DPU, wherein the DPU further includes a cache unit and a communication main line, wherein one end of the arbitration unit is connected to the cache unit, and the other end is connected to the communication main line, as shown in FIG. Figure 5 As shown, the device comprises:

[0078] The first transmission module 501 is used to transmit the transaction market data packet to the CPU through the communication main line if the transaction market data packet is received;

[0079] The second transmission module 502 is used to transmit the log data stored in the cache unit to the CPU through the communication main line when the transaction quotation data packet is transmitted, wherein the log data is collected by the DPU and written into the cache unit during the process of transmitting the transaction quotation data packet.

[0080] Furthermore, the first transmission module 501 of the embodiment of the present application is also used to read log data packets in the cache unit, wherein the log data is stored in the cache unit in the form of multiple log data packets; and send the log data packets to the CPU through the communication main line.

[0081] Furthermore, the first transmission module 501 of the embodiment of the present application is also used to read the log data packet in the first cache unit, wherein the log data packet is read by the first cache unit in the second cache unit when the log data is transmitted.

[0082] Furthermore, the DPU-based data transmission device in the embodiment of the present application also includes a third transmission module, which is specifically used to stop transmitting the log data packet and transmit the transaction market data packet through the communication main line if a transaction market data packet is received during the process of transmitting the log data packet to the CPU through the communication main line.

[0083] Furthermore, the DPU-based data transmission device in the embodiment of the present application also includes a detection module, which is specifically used to stop transmitting the log data packet during the transmission of the log data packet and detect whether there is a first log data packet being transmitted; if so, send a retention instruction to the first cache unit and add an error mark to the first log data packet, wherein the retention instruction is used to instruct the first cache unit to retain the first log data packet, and the error mark is used to instruct the CPU to delete the received first log data packet.

[0084] Furthermore, the second transmission module 502 of the embodiment of the present application is also used to obtain the first log data packet in the first cache unit when the transaction quotation data packet is transmitted, and transmit the first log data packet to the CPU through the communication main line.
