[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0027] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0028] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0029] In this application, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0030] With the development of the vehicle industry, "software-defined vehicles" has become an irreversible trend. Software accounts for an increasingly larger proportion of vehicle development, is becoming more complex, covers a wider range of interaction requirements, and has a shorter iteration cycle. Software has become an independent core component product, and the traditional signal-oriented software architecture is facing obvious pain points.

[0031] In the field of autonomous driving, the requirements for communication bandwidth and performance are becoming increasingly demanding. Simply using Ethernet to carry all data interactions can easily reach performance bottlenecks, and development costs will also increase dramatically. Please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of existing data transmission methods between chips. In this diagram, service 'a' in chip A and service 'b' in chip B transmit data via Ethernet. To reduce network communication burden, one aspect of this application provides a data transmission method based on a physical link. Please refer to [link to details]. Figure 2 , Figure 2 This is a schematic flowchart illustrating a data transmission method based on a physical link, as shown in an exemplary embodiment of this application. The data transmission method is applied to a target chip and includes at least steps S210 to S220, detailed below: S210: Detect whether a transmission instruction for transmitting target data has been received, and detect whether the usage frequency of the transmission data specified in the transmission instruction is less than a preset frequency; wherein, the target data is the data provided by the target service in the target chip.

[0032] The transmission instructions include information such as the specified target service, the specific content of the target data, and the transmission time.

[0033] The target service can proactively provide target data, for example, by periodically sending target data to other chips as a publisher; the target service can also passively provide target data, for example, by sending target data to other chips as a responder.

[0034] The preset frequency is a pre-defined parameter that defines the frequency of data usage. If the usage frequency of the corresponding data is greater than or equal to the preset frequency, the data is determined to be high-frequency data; if the usage frequency of the corresponding data is less than the preset frequency, the data is determined to be low-frequency data. Low-frequency data is transmitted via wired data exchange through a physical link interface, while high-frequency data is transmitted wirelessly via an Ethernet link interface.

[0035] Low-frequency data includes, but is not limited to, LiDAR dot matrix data and data read from or stored on solid-state drives on chips. High-frequency data includes, but is not limited to, camera data and UDS (Unified Diagnostic Services) diagnostic messages.

[0036] S220: If all are yes, then the target data is transmitted to the first physical link interface through the target preset virtual transmission interface, so that the target data is transmitted to the second physical link interface in other chips through the first physical link interface; wherein, the first physical link interface and the second physical link interface are connected through a physical link.

[0037] The target preset virtual sending interface belongs to the preset virtual sending interface; among which, the preset virtual sending interface includes the preset publish virtual sending interface and the preset response virtual sending interface.

[0038] The first physical link interface is an external interface belonging to the target chip, and the second physical link interface is an external interface belonging to other chips. Related data is transmitted in both directions via the physical link between these interfaces, eliminating the need for network communication and thus reducing network communication overhead.

[0039] In some embodiments, in Figure 2 Based on S210 to S220 of the data transmission method shown, this data transmission method also includes S230, which is described in detail below: S230: If it is detected that the frequency of use of the transmission data specified by the transmission command is less than the preset frequency, the target data is transmitted to the first Ethernet link interface through the target preset virtual transmission interface, so that the target data is transmitted to the second Ethernet link interface in other chips through the first Ethernet link interface; wherein, the first Ethernet link interface and the second Ethernet link interface are connected through an Ethernet link.

[0040] Upon detecting a transmission command, and if the target data specified in the transmission command is high-frequency data, the target data will be transmitted via the Ethernet link to split the high- and low-frequency data for transmission, thereby improving data transmission efficiency.

[0041] This embodiment sends target data from the target chip to the first physical link interface via a preset virtual transmission interface, and then transmits the target data to the second physical link interface of other chips via physical links connected to them. The chips are connected via physical links, establishing a connection between the corresponding physical link interface and the preset virtual interface. This allows for the transmission of target data between the virtual and physical interfaces without the need for network communication. Furthermore, the wired or wireless transmission method of the target data is determined based on the relationship between the usage frequency of the target data and a preset frequency, rather than solely relying on wireless network communication for data transmission. This diversion of data transmission reduces the burden on network communication.

[0042] In another exemplary embodiment of this application, a detailed description is provided of how to generate a preset virtual interface, that is, in Figure 2 Based on S210 to S220 of the data transmission method shown, this data transmission method further includes S21, which is described in detail below: S21: Generate a preset virtual interface based on the parameters of the target chip and the parameters of the first physical link interface; wherein the preset virtual interface includes a preset virtual transmitting interface and a preset virtual receiving interface.

[0043] The preset virtual interface is an interface that directly interfaces with the physical interface. For example, in this embodiment, the preset virtual sending interface interfaces with the first physical link interface to build a data transmission channel at different levels of software and hardware.

[0044] For example, the first physical link is a PCIe (PCI Express, a hardware-based direct connection technology) physical link, which can select x1 to x32 channels according to bandwidth requirements. At the system layer, the first physical link is encapsulated as a BSP (Board Support Package) interface. Specifically, after configuring the first physical link interface for the target chip, the system layer uses an adaptation tool to generate an adapted preset virtual interface based on the parameters of the target chip and the parameters of the first physical link. Among them, the preset virtual sending interface is the virtual interface that sends out the target data of the target chip, and the preset virtual receiving interface is the virtual interface that receives the received data transmitted from the physical link.

[0045] This embodiment provides a method for generating a preset virtual interface. Based on the parameters of the target chip and the parameters of the first physical link interface, an adapted preset virtual interface is generated, so that the preset virtual interface and the first physical link interface are connected to construct a data transmission channel at different software and hardware levels.

[0046] In another exemplary embodiment of this application, it is described in detail how to determine the target preset virtual transmission interface, that is, in Figure 2 Before S220 of the data transmission method shown, the data transmission method further includes S22 to S23, which are described in detail below: S22: If the communication mode specified by the transmission command is detected to be publish-subscribe mode, then the preset publish virtual sending interface will be used as the target preset virtual sending interface.

[0047] S23: If the communication mode specified by the transmission command is detected to be request-response mode, then the preset response virtual sending interface will be used as the target preset virtual sending interface.

[0048] The communication modes include PUB-SUB (publish-subscribe) communication mode and REQ-RSP (request-response) communication mode.

[0049] If it is a publish-subscribe mode, it means that the target chip, as the publisher, can periodically and proactively send the target data out, that is, send the target data to the first physical link interface through a preset publish virtual sending interface, so that the target data can be transmitted to the second physical link interface in other chips through the first physical link interface.

[0050] If it is a request-response mode, it means that the target chip acts as the responder and responds to the request by sending the target data outward. That is, the target data is sent to the first physical link interface through the preset response virtual sending interface, so that the target data can be transmitted to the second physical link interface in other chips through the first physical link interface.

[0051] This embodiment further illustrates that different communication modes are adapted to use different preset virtual sending interfaces, and provides preset virtual sending interfaces corresponding to publish-subscribe mode and request-response mode, so that target data can be securely sent to the first physical link interface through the corresponding preset virtual sending interface in different communication modes.

[0052] In another exemplary embodiment of this application, it is described in detail how to transmit target data to a first physical link interface through a preset virtual interface, so that the target data can be transmitted to a second physical link interface in other chips through the first physical link interface, that is, in Figure 2 The S220 shown further includes: transmitting the target data to the transmitting port in the first physical link interface through a preset virtual interface, so that the target data is transmitted to the receiving port in the second physical link in other chips through the transmitting port; wherein the transmitting port in the first physical link interface and the receiving port in the second physical link interface are connected through the same physical link.

[0053] Please see Figure 3 , Figure 3 This is a schematic diagram illustrating the connection structure between a target chip and other chips according to an exemplary embodiment of this application. SOC-A is the target chip, and SOC-B is one of the other chips. Both the first and second physical link interfaces are PCIe interfaces, each with a transmit port and a receive port. Both chips also have corresponding Ethernet interfaces, which are connected via an Ethernet link.

[0054] In SOC-A, service A transmits target data to the runtime through the corresponding SOA (Service-Oriented Architecture) service interface. If the usage frequency of the target data is less than the preset frequency, it is transmitted to the send port in the PCIe interface through a preset virtual interface, so that the target data is transmitted to the receive port in the PCIe interface of SOC-B through the PCIe physical link. It is evident that the send and receive ports are connected through a unified physical link, allowing data to be transmitted via the physical link without consuming network communication resources.

[0055] If the usage frequency of the target data is greater than or equal to a preset frequency, the target data is transmitted to the first Ethernet link interface through the target preset virtual transmission interface, so that the target data can be transmitted to the second Ethernet link interface in other chips through the first Ethernet link interface; wherein, the first Ethernet link interface and the second Ethernet link interface are connected via an Ethernet link, without occupying a physical link channel. Similarly, data used by other chips at a frequency greater than or equal to the preset frequency can also be transmitted to the first Ethernet link interface through the second Ethernet link interface, so that the target chip can receive other data through the Ethernet link.

[0056] This embodiment further describes how the target data is transmitted from the sending port in the first physical link interface to the receiving port in the second physical link interface to realize the data transmission method of the physical link, which does not occupy network communication resources and reduces the network communication burden.

[0057] In another exemplary embodiment of this application, how to receive other data transmitted by other chips is described in detail; please refer to [link to relevant documentation]. Figure 4 , Figure 4 Based on Figure 2 The exemplary embodiment shown illustrates a flowchart of another data transmission method based on a physical link. This data transmission method, in the example described... Figure 2 Based on S210 to S220 shown, S410 to S420 are also included, which are described in detail below: S410: Detects whether the first physical link interface receives other data transmitted by other chips, and detects whether the usage frequency of other data is less than the preset frequency.

[0058] Other data refers to data provided by related services in other chips, which are used less frequently than a preset frequency. The first physical link interface can not only send data but also receive data.

[0059] S420: If all are true, then transmit the other data to the target interface corresponding to the target service through the target preset virtual receiving interface, so that the target service can receive the other data.

[0060] The target preset virtual receiving interface is a preset virtual receiving interface determined according to the communication mode.

[0061] If the first physical link interface detects that external data has been received, the external data is received through the corresponding preset virtual receiving interface and transmitted to the target interface corresponding to the target service in the target chip so that the target service can receive other data.

[0062] This embodiment provides a method for receiving external data through a physical link interface. By using a target preset virtual receiving interface, the external data received by the first physical link interface is transmitted to the target interface corresponding to the target service, so that the target service can receive other data.

[0063] In another exemplary embodiment of this application, it is described in detail how to determine the target preset virtual receiving interface, that is, in Figure 4 Before S420 of the data transmission method shown, the data transmission method further includes S41 to S43, which are described in detail below: S41: Determine the target preset virtual receiving interface based on the communication mode corresponding to other data.

[0064] The preset virtual interfaces corresponding to the PUB-SUB communication mode include: a preset publish virtual sending interface and a preset subscribe virtual receiving interface.

[0065] The preset virtual interfaces corresponding to the REQ-RSP communication mode include: a preset response virtual sending interface and a preset request virtual receiving interface.

[0066] The preset virtual receiving interfaces in this embodiment include: a preset subscription virtual receiving interface and a preset request virtual receiving interface.

[0067] S42: If the communication mode corresponding to other data is publish-subscribe mode, then the preset subscription virtual receiving interface will be used as the target preset virtual receiving interface.

[0068] S43: If the communication mode corresponding to other data is request-response mode, then the preset request virtual receiving interface will be used as the target preset virtual receiving interface.

[0069] If the communication mode is PUB-SUB communication mode, then the target preset virtual receiving interface is the preset subscription virtual receiving interface.

[0070] If the communication mode is REQ-RSP communication mode, then the target preset virtual receiving interface is the preset request virtual receiving interface.

[0071] This embodiment further illustrates that different communication modes are adapted to use different preset virtual receiving interfaces, and provides preset virtual receiving interfaces corresponding to publish-subscribe mode and request-response mode, so as to receive other external data through the corresponding preset virtual receiving interface in different communication modes and transmit it securely to the target service.

[0072] In another exemplary embodiment of this application, a detailed description is provided of how to detect whether the first physical link interface has received other data transmitted by other chips, that is, in Figure 4 The data transmission method shown in step S410 further includes: detecting whether the receiving port in the first physical link interface receives other data transmitted by the sending port in the second physical link interface; wherein the receiving port in the first physical link interface and the sending port in the second physical link interface are connected through the same physical link.

[0073] Reference Figure 3 As shown, other data in SOC-B is transmitted from the send port of its PCIe interface (i.e., the send port of the second physical link interface in this embodiment) to the receive port of the PCIe interface of SOC-A (i.e., the receive port of the first physical link interface in this embodiment) via the PCIe physical link.

[0074] This embodiment further illustrates how to detect whether the first physical link interface receives other data transmitted by other chips. By targeting the receiving port in the first physical link interface to detect whether it receives other data, it can accurately determine whether there is external data transmitted through the physical link.

[0075] Please see Figure 5 , Figure 5 This is a schematic diagram of a PCIe-based SOA integrated logical architecture illustrated in an exemplary embodiment of this application. The following is a detailed description of each module shown in the diagram: PCIe physical link: Implement the PCIe bus link in hardware, and select from x1 to x32 channels to meet different bandwidth requirements.

[0076] System layer: The PCIe link is encapsulated as a BSP interface to implement interfaces for data sending and receiving.

[0077] Abstract Interface Layer: Because different chips may have hardware and system differences, the BSP interface will also be different. Adaptation tools are used to abstract it and generate a unified interface.

[0078] Runtime: Implements two communication modes, PUB-SUB and REQ-RSP, which conform to SOA distributed communication, as well as the basic functions supporting these two communication modes, including: service queue, service registration, [stop] providing services, [stop] requesting services, etc.

[0079] Service Implementation Layer: SOA requires the implementation of three service interfaces: Method, Event, and Field. Based on the Runtime, the business encapsulation of these three service interfaces is implemented, and service discovery functionality is provided.

[0080] Service Interface Layer: An abstraction of the three service interfaces: Method, Event, and Field, facilitating calls from functional service programs.

[0081] This embodiment uses a PCIe-based SOA integration method, abstracting interface standards to adapt to multi-chip PCIe interfaces. Specifically, it offloads Ethernet-based data transmission through PCIe physical links, reducing network load and thus enhancing system throughput and stability.

[0082] Another aspect of this application provides a data transmission device based on a physical link, such as... Figure 6 As shown, Figure 6 This is a schematic diagram illustrating the structure of a physical link-based data transmission device according to an exemplary embodiment of this application. The data transmission device 600 is applied to a target chip and includes: The detection module 610 is used to detect whether a transmission instruction for transmitting target data has been received, and to detect whether the usage frequency of the transmission data specified in the transmission instruction is less than a preset frequency; wherein, the target data is the data provided by the target service in the target chip.

[0083] The sending module 630 is used to transmit the target data to the first physical link interface through the target preset virtual sending interface if all conditions are met, so that the target data can be transmitted to the second physical link interface in other chips through the first physical link interface; wherein the first physical link interface and the second physical link interface are connected by a physical link.

[0084] In an alternative embodiment, the data transmission device 600 further includes: The wireless transmission module is used to transmit target data to a first Ethernet link interface through a target preset virtual transmission interface if it detects that the frequency of the data to be transmitted specified by the transmission command is less than a preset frequency, so that the target data can be transmitted to a second Ethernet link interface in other chips through the first Ethernet link interface; wherein the first Ethernet link interface and the second Ethernet link interface are connected through an Ethernet link.

[0085] In an alternative embodiment, the data transmission device 600 further includes: The preset virtual interface generation module is used to generate a preset virtual interface based on the parameters of the target chip and the parameters of the first physical link interface; wherein, the preset virtual interface includes a preset virtual transmitting interface and a preset virtual receiving interface.

[0086] In an alternative embodiment, the data transmission device 600 further includes: The first target preset virtual sending interface confirmation module is used to use the preset publishing virtual sending interface as the target preset virtual sending interface if the communication mode specified by the transmission command is detected to be publish-subscribe mode.

[0087] The second target preset virtual sending interface confirmation module is used to use the preset response virtual sending interface as the target preset virtual sending interface if the communication mode specified by the transmission command is detected to be the request-response mode.

[0088] In an alternative embodiment, the sending module 630 further includes: The transmitting unit is used to transmit target data to the transmitting port in the first physical link interface through a preset virtual interface, so that the target data can be transmitted to the receiving port in the second physical link in other chips through the transmitting port; wherein the transmitting port in the first physical link interface and the receiving port in the second physical link interface are connected through the same physical link.

[0089] In an alternative embodiment, the data transmission device 600 further includes: Other data detection modules are used to detect whether the first physical link interface receives other data transmitted by other chips.

[0090] Other data receiving modules are used, if yes, to transmit other data to the target interface corresponding to the target service through the target preset virtual receiving interface, so that the target service can receive other data.

[0091] In an alternative embodiment, the data transmission device 600 further includes: The target preset virtual receiving interface module is used to determine the target preset virtual receiving interface based on the communication mode corresponding to other data.

[0092] The preset subscription virtual receiving interface module is used to select the preset subscription virtual receiving interface as the target preset virtual receiving interface if the communication mode corresponding to other data is publish-subscribe mode.

[0093] The preset request virtual receiving interface module is used to select the preset request virtual receiving interface as the target preset virtual receiving interface if the communication mode corresponding to other data is request-response mode.

[0094] In one alternative approach, the other data detection modules further include: Other data detection units are used to detect whether the receiving port in the first physical link interface receives other data transmitted by the sending port in the second physical link interface; wherein the receiving port in the first physical link interface and the sending port in the second physical link interface are connected through the same physical link.

[0095] The data transmission device of this application transmits target data from the target chip to the first physical link interface through a preset virtual transmission interface, and then transmits the target data to the second physical link interface of other chips through physical links connected to them. The chips are connected via physical links, establishing a connection between the corresponding physical link interface and the preset virtual interface. This allows for the transmission of target data between the virtual and physical interfaces without the need for network communication. Furthermore, based on the relationship between the usage frequency of the target data and a preset frequency, the device determines whether the target data is transmitted via wired or wireless means, rather than solely through wireless network communication. This diversion of data transmission reduces the burden on network communication.
