Description

Technical Field

Detailed Implementation

[0027] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods and apparatus described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0028] The embodiments described in the following examples of this disclosure are not intended to represent all embodiments consistent with this disclosure. Rather, they are merely examples of methods, protocol stacks, apparatuses, etc., consistent with some aspects of this disclosure as detailed in the appended claims.

[0029] Figure 1 This is a schematic diagram of a UniPro protocol stack. Figure 1 As shown, the UniPro protocol stack can include a transport layer, a network layer, a data link layer, and a physical adaptation layer.

[0030] The UniPro protocol stack can split and encapsulate unlimited data packets from the application layer (of the terminal) into multiple PDUs with length limits, and add appropriate headers to each PDU at each layer. See also... Figure 2 The transport layer needs to include an End of Message (EOM) flag in the header added to the PDU. The EOM indicates whether the corresponding PDU is the end segment (last segment) of the data packet.

[0031] However, the application layer typically sends the end-of-message identifier to the UniPro protocol stack only when sending the last character of a data packet. This allows the transport layer to determine the end of the data packet based on the received end-of-message identifier. The transport layer then appends the header to each PDU upon receiving the end-of-message identifier, impacting the transmission efficiency of each PDU. For example, see... Figure 3After the transport layer determines the PDU to be the end segment, it can set the EOM of the PDU to 1 (indicating that the corresponding PDU is the end segment of the data packet) and set the EOM of other PDUs to 0 (indicating that the corresponding PDU is not the end segment of the data packet). Then, each PDU is sent through the network layer, data link layer and physical adaptation layer in sequence and sent to the Universal Flash Storage (UFS) system, which affects the efficiency of each PDU being stored in the UFS system.

[0032] In one related technology, see Figure 4 If the transport layer does not obtain the message end marker, it can set the EOM of each obtained PDU to 0 and send each PDU sequentially through the network layer, data link layer, and physical adaptation layer. If the transport layer obtains the message end marker, it can split the current PDU. That is, it encapsulates the data in the current PDU that has not been transmitted to the network layer into a new PDU (e.g., ...). Figure 4 The PDU' is then processed by setting its EOM to 1 and then sending the PDU' through the network layer, data link layer and physical adaptation layer in sequence.

[0033] However, splitting data that could be integrated into a single PDU into two PDUs for transmission increases the number of packet headers, thereby introducing additional transmission overhead.

[0034] In another related technology, if the transport layer cannot determine whether a PDU is the end segment of a data packet to be processed when encapsulating it, it can temporarily store the PDU header and the data in the PDU that are in the same processing cycle as the header, and send the other data in the PDU as the PDU body through the network layer to the data link layer. After the transport layer determines the EOM value corresponding to the PDU, it can fill in the PDU header based on the EOM value, and send the filled header and the temporarily stored data through the network layer to the data link layer. The data link layer can integrate the received PDU body, the filled header, and the data temporarily stored by the transport layer to transmit the integrated data to the corresponding location through the physical adaptation layer.

[0035] However, the above method requires additional temporary storage units in the transport layer, increasing transmission overhead. Furthermore, the temporary storage of packet headers and data in the transport layer also increases the latency of the entire data processing flow, affecting the transmission efficiency of the PDU.

[0036] Therefore, to address the aforementioned problems, this disclosure provides a data processing method, apparatus, storage medium, program product, and chip system. By first setting the end flag of the target data segment to a preset value, the transmission preparation process for the target data segment can proceed without waiting for the target value of the end flag. Subsequently, when the target value of the end flag is obtained, the transmission process for the target data segment can be started simply by updating the value of the end flag to the target value, thereby improving the transmission efficiency of the target data segment.

[0037] The solutions provided by the embodiments of this disclosure will now be described in conjunction with the accompanying drawings.

[0038] Figure 5 This is a flowchart illustrating a data processing method according to some embodiments of the present disclosure. The data processing methods illustrated in some embodiments of the present disclosure can be applied to a data processing apparatus, which may include a protocol stack such as the UniPro protocol stack for performing data processing. The data processing method illustrated in some embodiments of the present disclosure will be described in detail below, taking this data processing apparatus as the execution subject.

[0039] like Figure 5 As shown, some embodiments of this disclosure illustrate a data processing method that may include the following steps S501-S502: S501: Obtain the target data segment of the data packet to be sent, and set the value of the end flag bit of the target data segment to a preset value.

[0040] The data packets to be sent can be obtained from a data source. The data source can be a device or a software or hardware module included in the device. For example, the data source can be an application software in a mobile phone. This application embodiment does not limit this.

[0041] The data packets to be sent can be a collection of data continuously output by the data source. The length of each data packet output by the data source can vary; that is, the data source can continuously output corresponding data packets based on the actual situation, and the length of the data packets output in different outputs can be different, rather than being limited to outputting only a fixed-length data packet each time.

[0042] Since the length of the data packets output by the data source is not fixed, and the data source may need to continuously output a large amount of data to achieve the output of the complete data packet to be sent, the data processing device can perform group processing on the received data (the data included in the data packet to be sent) to split the data packet to be sent into at least one data segment (the target data segment in this application embodiment can be any of the at least one data segment), thereby ensuring that subsequent data can be successfully transmitted.

[0043] In one implementation, the data processing device can group the received data based on a length threshold. Taking a length threshold of 5 characters as an example, the data source can continuously output a series of data (data1, data2, data3...), with each data item occupying one character. When the data processing device receives data1, it can divide data1 into data segment 1, and continue dividing the received data2-data5 into data segment 1. In this case, the data processing device can determine that data segment 1 has reached the length threshold (including 5 characters). Then, when the data processing device receives data6, it can divide data6 into data segment 2, and continue dividing the received data6-data10 into data segment 2. In this case, the data processing device can determine that data segment 2 has reached the length threshold (including 5 characters). Afterward, the data processing device can continue to group the received data11, data12, etc., to obtain more data segments.

[0044] The data processing device can generate a header for each data segment before it begins splitting it. For example, the data processing device generates the header for data segment 1 when it receives data1 in the aforementioned example. As another example, the data processing device generates the header for data segment 2 when it receives data6 in the aforementioned example. The header of a data segment may include a length bit indicating the length of the data segment, an end flag bit indicating whether the data segment is the end of a data packet, and a destination address bit indicating the receiving location of the data segment, etc.

[0045] Because the data source sends the message end marker to the data processing device only when sending the last character of the data packet to be sent, and the data processing device has not yet obtained the message end marker when generating the data segment header and splitting the data segments, it cannot determine in advance whether the current data segment is the last segment of the data packet. Therefore, the value of the end marker can be set to a preset value. This preset value can be a pre-set fixed value, such as 0 (a value of 0 in the end marker indicates that the corresponding data segment is not the end segment of the data packet to be sent). In this way, the data processing device can quickly complete the splitting of the data segment and the preliminary configuration of the corresponding data segment header without waiting for the message end marker to be obtained, thereby advancing the subsequent data processing flow and avoiding transmission delays caused by waiting for the message end marker to be obtained.

[0046] It should be noted that the aforementioned length threshold can be determined based on the maximum transmission unit (MTU) required by the data transmission protocol followed by the data processing device. The length of each data segment split by the data processing device based on the length threshold is less than or equal to the value corresponding to that maximum MTU, to ensure that each data segment will not fail to transmit normally during subsequent transmission due to exceeding the length limit.

[0047] S502: Determine the target value of the end flag and update the value of the end flag from the preset value to the target value.

[0048] The target value indicates whether the target data segment is the end segment of a data packet. The data processing device generates a target value for the end flag bit of each data segment it determines is the end segment of a data packet. Then, based on the target value of the end flag bit, the value of the end flag bit in the header of the corresponding data segment is updated from a preset value to the target value. After the update, the end flag bit in the header of the data segment accurately reflects whether the corresponding data segment is the end segment of the data packet. In subsequent data transmission, the receiving end can quickly identify the position of each data segment based on the target value of the end flag bit. For example, if the target value of the end flag bit of the target data segment is 0, it can be determined that the target data segment is not the end segment, and other data segments need to be received; if the target value of the end flag bit of the target data segment is 1, it can be determined that the target data segment is the end segment, and no other data segments need to be received. The received data can then be integrated and processed accordingly.

[0049] As can be seen, by first setting the end flag of the target data segment to a preset value, the transmission preparation process for the target data segment can be advanced without waiting for the target value of the end flag. Subsequently, when the target value of the end flag is obtained, the transmission process for the target data segment can be started simply by updating the value of the end flag to the target value, which can improve the transmission efficiency of the target data segment.

[0050] In some embodiments of this disclosure, step S502, determining the target value of the end flag bit, includes: during the process of obtaining the target data segment, determining the target value of the end flag bit based on the result of obtaining the message end identifier; the message end identifier is sent by the data source when the last character of the data packet is sent.

[0051] In this process, the data source does not send a separate message end marker during the output of data packets. Instead, it outputs the message end marker synchronously with the last character of the data packet. Therefore, during the generation of the target data segment, the data processing device can determine whether the target data segment is the end data segment of the data packet based on the result of obtaining the message end marker, and generate the target value of the end flag bit of the target data segment.

[0052] As can be seen, the data processing device can determine the target value of the end flag bit during the generation of the target data segment, without the need to add an independent step of flag acquisition and target value determination after the target data segment is generated, thus avoiding redundancy and time consumption in the overall data processing flow.

[0053] In some embodiments of this disclosure, see Figure 6 The above-mentioned determination of the target value of the end flag bit based on the result of obtaining the message end identifier includes: if the message end identifier is obtained, the target value of the end flag bit is determined to be a first value; the first value is used to indicate that the target data segment is the end data segment of the data packet.

[0054] In the process of obtaining the target data segment, if the data processing device confirms that it has obtained the message end identifier, it can determine the target value of the end flag bit corresponding to the target data segment as the first value (for example, determine the target value of the end flag bit corresponding to the target data segment as 1) to clarify that the target data segment is the end data segment of the data packet.

[0055] This method of determining the end of a message directly by associating the acquired message end marker with the determined first value is logically clear and direct, eliminating the need for complex intermediate determination processes and improving the efficiency of the data processing device in determining the target value of the end marker. Furthermore, the first value clearly indicates that the corresponding target data segment is the end of the data packet, providing a clear and unambiguous basis for subsequent data processing device updates to the end marker value, thus avoiding update errors caused by ambiguous determination criteria.

[0056] In some embodiments of this disclosure, see also [link to previous document]. Figure 6 The above-mentioned determination of the target value of the end flag bit based on the result of obtaining the message end identifier includes: if the message end identifier is not obtained, the target value of the end flag bit is determined to be a second value; the second value is used to indicate that the target data segment is not the end data segment of the data packet.

[0057] In the process of obtaining the target data segment, if the data processing device confirms that the message end identifier has not been obtained, it can determine the target value of the end flag bit corresponding to the target data segment as a second value (for example, determine the target value of the end flag bit corresponding to the target data segment as 0) to clarify that the target data segment is not the end data segment of the data packet.

[0058] This method of directly linking the acquisition of the message end marker with the determination of the second value is logically clear and direct, eliminating the need for complex intermediate determination processes and improving the efficiency of the data processing device in determining the target value of the end marker. Furthermore, the second value clearly indicates that the corresponding target data segment is not the end segment of the data packet, providing a clear and unambiguous basis for subsequent data processing device updates of the end marker value, avoiding update errors caused by ambiguous determination criteria.

[0059] In some embodiments of this disclosure, the data processing method provided in the above embodiments can be applied to a data processing apparatus, which may include a transport layer and a data link layer. Step S501, setting the value of the end flag bit of the target data segment to a preset value, includes: setting the value of the end flag bit of the target data segment to a preset value through the transport layer, and sending the target data segment to the data link layer.

[0060] The transport layer can acquire data sent by the data source and perform grouping processing on the acquired data to split the data packet to be sent into at least one data segment, thereby ensuring that subsequent data can be successfully transmitted. For a description of the transport layer's grouping processing of the acquired data, please refer to the description of the data processing device's grouping processing of the acquired data in the foregoing embodiments, which will not be repeated here.

[0061] Furthermore, the transport layer can add a header (also referred to as a transport layer header in this embodiment) to the target data segment. The transport layer header may include fields serving end-to-end application data transmission and segmentation management. For example, the transport layer header may include a length bit, an end flag bit, a source port identifier (corresponding to the sending application port of the data packet), a destination port identifier (corresponding to the receiving application port of the data packet), a command field (used to identify the transmission command type corresponding to the target data segment, such as data transmission, acknowledgment feedback, etc.), and a transport layer check field (used to verify whether errors occur during the internal flow of transport layer data). The transport layer can set the value of the end flag bit to a preset value and send the target data segment configured with the transport layer header to the data link layer. A description of the preset value can be found in the description in the foregoing embodiments, and will not be repeated here.

[0062] In one implementation, the data processing device further includes a network layer. The transport layer can send the target data segment to the network layer, which then forwards it to the data link layer. Upon receiving the target data segment from the transport layer, the network layer can add a network layer header. This header may include fields for routing and addressing, such as a source network address (corresponding to the network identifier of the data sending device), a destination network address (corresponding to the network identifier of the data receiving device), a protocol type field (identifying the transport layer protocol type corresponding to the upper-layer data), a routing priority field (used to distinguish the transmission priority of different data), and a network layer checksum field (used to verify the integrity of the network layer header itself). The network layer can adapt the transmission path of the target data segment to ensure it is accurately delivered to the corresponding receiving end. Finally, the network layer can send the target data segment, configured with the transport layer header and network layer header, to the data link layer.

[0063] As can be seen, by setting the end flag of the target data segment to a preset value at the transport layer and sending the target data segment to the data link layer, the transport layer can quickly advance the flow of the target data segment within the data processing device without waiting for the determination of the target value of the end flag. Furthermore, it allows the data link layer to receive the target data segment in advance, avoiding process stagnation caused by the transport layer waiting for the target value determination, thus improving the processing efficiency of the target data segment and consequently improving the processing efficiency of the entire data packet to be sent.

[0064] Figure 7 This is a flowchart illustrating a method for updating the value of an end flag bit according to some embodiments of the present disclosure. Figure 7 As shown, step S502 above, determining the target value of the end flag and updating the value of the end flag from the preset value to the target value, includes the following steps S701-S702: S701: Determine the target value of the end flag bit through the transport layer and send the target value of the end flag bit to the data link layer.

[0065] Specifically, the transport layer can generate a target value for the end flag bit of each data segment it determines as to whether it is the end segment of a data packet. The transport layer can then send the target value of the end flag bit to the data link layer.

[0066] In one implementation, when the transport layer sends a target value to the data link layer, it can send the target value along with the associated information of the corresponding data segment (such as the sequence number and length information of the data segment). This associated information can be consistent with the information carried by the target data segment previously sent by the transport layer to the data link layer, enabling the data link layer to quickly and accurately match the received target value with the target data segment, thus avoiding a correspondence error between the target value and the data segment.

[0067] In one implementation, the transport layer can directly send the target value of the obtained end flag to the data link layer without going through other intermediate layers for forwarding. This shortens the transmission path of the target value, improves transmission efficiency, and allows the data link layer to receive the target value faster, thereby enabling timely updates to the subsequent end flag and ensuring the efficient progress of the data processing flow.

[0068] In another implementation, the transport layer can send the target value obtained from the end flag to the network layer, which then forwards the target value to the data link layer. This network layer forwarding method ensures that the transmission of the target value follows the same internal flow logic as the transmission of the target data segment, guaranteeing the consistency of the transmission mechanism within the data processing device. Furthermore, the forwarding function of the network layer can adapt to the architecture design of the data processing device, including the network layer, ensuring that in scenarios requiring path planning through the network layer, the target value arrives at the data link layer synchronously with the transmission rhythm of the target data segment. This avoids matching delays between the target value and the target data segment due to differences in transmission paths, thus ensuring the stability of the data processing flow.

[0069] S702: Through the data link layer, update the value of the end flag bit of the target data segment from the preset value to the target value.

[0070] When the data link layer receives the target value sent by the transport layer, it can match the corresponding target data segment and update the value of the end flag of the target data segment to the target value, so that the end flag can accurately identify the position of the target data segment in the data packet and provide support for the transmission of subsequent target data segments.

[0071] This design, where the transport layer determines and sends the target value of the end flag, and the data link layer performs the numerical update, ensures precise coordination between the target value determination and update processes, avoiding process disconnects within the data processing device. The transport layer proactively sends the target value, ensuring the data link layer can obtain accurate update information promptly without additional queries or waiting, thus improving the efficiency of the end flag update. The data link layer, by directly updating the value, enables the target data segment to quickly carry accurate end status information, providing a reliable guarantee for the smooth transmission of subsequent target data segments, thereby improving the overall data packet processing and transmission efficiency.

[0072] In some embodiments of this disclosure, the data link layer includes a buffer unit; sending a target data segment to the data link layer via the transport layer includes: sending the target data segment to the buffer unit via the transport layer in the system clock domain to write the target data segment to the buffer unit. Sending a target value of an end flag bit to the data link layer via the transport layer includes: sending the target value of the end flag bit to the buffer unit via the transport layer in the system clock domain to write the target value of the end flag bit to the buffer unit.

[0073] The system clock domain refers to the unified clock synchronization reference within the data processing device. The operations of each functional module in the data processing device (including the buffer units of the transport layer and data link layer) can be executed according to the clock reference, thereby ensuring the timing consistency of data transmission and processing within the data processing device.

[0074] In this system, the transport layer and the buffer unit interact with each other based on the same clock cycle. This avoids transmission delays or loss of target data segments or values, or misordering of their reception, caused by timing deviations in different clock domains. Furthermore, the transmit and write operations performed by the transport layer under a unified clock domain enable the buffer unit to accurately store target data segments and their corresponding target values ​​in the order of reception. This ensures a stable correspondence between the same data segment and its target value within the buffer unit, eliminating the need for additional timing calibration or order adjustment. This provides a reliable timing-level guarantee for the data link layer to quickly match data segments and target values ​​and efficiently update the end flag.

[0075] In some embodiments of this disclosure, the buffer unit described above is a static random access memory.

[0076] Static Random Access Memory (SRAM) features fast read / write speeds and no need for dynamic refresh, enabling it to precisely match the high-speed data transmission rhythm of the transport layer under the system clock domain, as well as the buffer unit's need for rapid storage of target data segments and end flag values. When the transport layer sends target data segments and target values ​​according to the system clock cycle, SRAM can receive and complete the write operation immediately without waiting for an additional refresh cycle, avoiding data transmission timing deviations caused by storage latency and ensuring the synchronous storage efficiency of target data segments and corresponding target values. Furthermore, the stable storage characteristics of SRAM ensure that target data segments and target values ​​maintain data integrity during storage, preventing data loss or errors due to the inherent characteristics of the storage medium itself. This provides reliable storage support for the data link layer to subsequently quickly read and match data segments and target values, and efficiently execute end flag update operations, thus meeting the high-efficiency requirements of data processing devices for data transmission and processing.

[0077] In some embodiments, the buffer unit may also be a dynamic random access memory, a register set, a first-in-first-out memory, a ferroelectric random access memory, etc., and the embodiments of this application are not limited thereto.

[0078] In some embodiments of this disclosure, the data link layer further includes a processing unit; step S702, updating the value of the end flag bit of the target data segment from a preset value to a target value through the data link layer, includes: through the processing unit, reading the target data segment and the target value of the end flag bit from the buffer unit in the transmit clock domain, and updating the value of the end flag bit of the target data segment from the preset value to the target value.

[0079] The transmit clock domain serves as the timing reference for the data link layer when sending data. Its timing is adapted to the transmission requirements of the data transmission link, ensuring that the updated target data segment can be sent stably according to the link's timing requirements. When the processing unit performs operations under the transmit clock domain, it can read the target data segment and its corresponding end flag value from the buffer unit in a preset order based on the storage association between the target data segment and its corresponding target value. After reading, the processing unit can locate the end flag field in the header of the target data segment and replace its value with the read target value. The entire update process is synchronized with the timing of the transmit clock domain, ensuring both the accuracy of the end flag update and the ability of the updated target data segment to instantly adapt to the transmission timing of the transmit clock domain. This allows it to enter the subsequent transmission process without additional timing calibration, further improving the continuity and efficiency of data processing and transmission.

[0080] Figure 8 This is a schematic diagram illustrating the structure of a data processing apparatus according to some embodiments of the present disclosure. Figure 8 As shown in some embodiments of this disclosure, the data processing apparatus includes a transport layer and a data link layer.

[0081] The transport layer is used to acquire the target data segment of the data packet to be sent and set the value of the end flag bit of the target data segment to a preset value; the transport layer is also used to determine the target value of the end flag bit. The data link layer is used to update the value of the end flag bit from the preset value to the target value; the target value is used to indicate whether the target data segment is the end data segment of the data packet.

[0082] In some embodiments of this disclosure, in determining the target value of the end flag bit, the transport layer is specifically used to: determine the target value of the end flag bit based on the result of obtaining the message end identifier during the process of obtaining the target data segment; the message end identifier is sent by the data source when the last character of the data packet is sent.

[0083] In some embodiments of this disclosure, in determining the target value of the end flag bit based on the result of obtaining the message end identifier, the transport layer is specifically used to: if the message end identifier is obtained, determine the target value of the end flag bit as a first value; the first value is used to indicate that the target data segment is the end data segment of the data packet.

[0084] In some embodiments of this disclosure, in determining the target value of the end flag bit based on the result of obtaining the message end identifier, the transport layer is specifically used to: if the message end identifier is not obtained, determine that the target value of the end flag bit is a second value; the second value is used to indicate that the target data segment is not the end data segment of the data packet.

[0085] In some embodiments of this disclosure, when setting the value of the end flag bit of the target data segment to a preset value, the transport layer is specifically used to: set the value of the end flag bit of the target data segment to a preset value and send the target data segment to the data link layer; In determining the target value of the end flag, the transport layer is specifically used to: determine the target value of the end flag and send the target value of the end flag to the data link layer; In updating the end flag value from the preset value to the target value, the data link layer is specifically used to: update the end flag value of the target data segment from the preset value to the target value.

[0086] In some embodiments of this disclosure, Figure 9 This is a schematic diagram illustrating the structure of a data link layer according to some embodiments of this disclosure. Figure 9 As shown, the data link layer may include a buffer unit. Specifically, the transport layer is used to: send a target data segment to the buffer unit under the system clock domain to write the target data segment into the buffer unit; and send the target value of the end flag bit to the buffer unit under the system clock domain to write the target value of the end flag bit into the buffer unit.

[0087] In some embodiments of this disclosure, the buffer unit is a static random access memory.

[0088] In some embodiments of this disclosure, see also [link to previous document]. Figure 9 The data link layer also includes a processing unit; the processing unit is used to: read the target value of the target data segment and the end flag bit from the buffer unit in the transmit clock domain, and update the value of the end flag bit of the target data segment from the preset value to the target value.

[0089] Regarding the apparatus in the above embodiments, the specific manner in which each module performs its operation can be referred to the description in the embodiments of the method, and will not be repeated here.

[0090] The data processing apparatus shown in some embodiments of this disclosure will now be described in detail with reference to specific scenarios.

[0091] See Figure 10The data source can continuously output a series of data (data1, data2, data3...), with each data item occupying one character. The transport layer can group the received data to split the data packet to be sent into data segment 1 (including data1-data5), data segment 2 (including data6-data10), data segment 3 (including data11-data15), etc. The transport layer can also configure a header for each data segment, set the end flag bit in the header of each data segment to 0 (indicating that the corresponding data segment is not the end segment of the data packet to be sent), and, under the system clock domain, send each data segment with configured headers to the data link layer through the network layer.

[0092] During the process of obtaining data segment 1, the transport layer did not receive the message end identifier sent by the data source. Therefore, it determined that the target value of the end flag bit of data segment 1 was 0 (0 is the second value in the embodiment of this application). The transport layer can send the target value 0 to the data link layer in the system clock domain. The data link layer can read data segment 1 and the target value 0 in the transmission clock domain, and update the end flag bit included in the packet header of data segment 1 from 0 to 0, so as to send the updated data segment 1 (such as sending it to the physical adaptation layer included in the data processing device, and sending it to the external storage system through the physical adaptation layer).

[0093] During the process of obtaining data segment 2, the transport layer did not receive the message end identifier sent by the data source. Therefore, it determined that the target value of the end flag bit of data segment 2 was 0 (0 is the second value in the embodiment of this application). The transport layer can send the target value 0 to the data link layer in the system clock domain. The data link layer can read data segment 2 and the target value 0 in the transmission clock domain, and update the end flag bit included in the packet header of data segment 2 from 0 to 0, so as to send the updated data segment 2 (such as sending it to the physical adaptation layer included in the data processing device, and sending it to the external storage system through the physical adaptation layer).

[0094] During the process of obtaining data segment 3, the transport layer receives the message end identifier sent by the data source, and therefore determines that the target value of the end flag bit of data segment 3 is 1 (1 is the first value in the embodiment of this application). The transport layer can send the target value 1 to the data link layer in the system clock domain. The data link layer can read data segment 3 and target value 1 in the transmission clock domain, and update the end flag bit included in the packet header of data segment 3 from 0 to 1, so as to send the updated data segment 3 (such as sending it to the physical adaptation layer included in the data processing device, and sending it to the external storage system through the physical adaptation layer).
