Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to an output matching circuit and a data output system for different data links. Background Art

[0002] The intelligent driving system architecture requires that the surround view data collected by the intelligent driving module be bypassed to the cockpit module. The cockpit module then uses this data to implement a 360-degree surround view function, providing the driver with real-time visual information of the vehicle's surroundings, enhancing driving safety and convenience.

[0003] There are two common access solutions currently used in the industry for bypassing the surround view data transmission from the intelligent driving module to the cockpit module. The first solution is to build a data link with a data transmission bandwidth of 12Gbps to achieve efficient transmission of surround view data. The second solution is to build two data links with a data transmission bandwidth of 6Gbps each, and the two links work in parallel to complete the surround view data transmission task.

[0004] It's worth noting that these two different surround view data access solutions differ in data transmission bandwidth, signal characteristics, and system architecture compatibility, leading to different serializer solutions required for data transmission. As a key technical link in ensuring accurate and stable data transmission, the selection and adaptation of the serializer solution has a significant impact on the performance and reliability of the entire system.

[0005] To sum up, how to enable the intelligent driving module to simultaneously achieve the matching of the above two different data links with the cockpit module has become one of the technical problems that technical personnel in this field urgently need to solve.

[0050] Example 1

[0051] Please refer to Figure 1-3 The embodiment of the present invention provides an output matching circuit for different data links, including a first connector 1, an adapter board 2, a deserializer chip 3, a system-level chip 4, a serializer chip 5, and a second connector 6; wherein,

[0052] The adapter board 2 is a key connection component in the circuit, and is electrically connected to the second connector 6 and the system-on-chip 4. This connection ensures that signals can be transmitted efficiently and stably between the system-on-chip 4 and the second connector 6.

[0053] The system-level chip 4 plays the role of the core controller in the circuit. It establishes a connection with the deserializer chip 3 and is responsible for accurately identifying the type of the second connector 6. Specifically, there are two types of second connectors 6, namely single-channel connectors 601 and dual-channel connectors 602. Through built-in logical judgment and configuration programs, the system-level chip 4 can perform corresponding configuration operations on the deserializer chip 3 according to the actual type of the second connector 6. When the second connector 6 is a single-channel connector 601, the system-level chip 4 configures the deserializer chip 3 to output MIPI interface signals using the four-channel DPHY physical layer standard; and when the second connector 6 is a dual-channel connector 602, the system-level chip 4 configures the deserializer chip 3 to output MIPI interface signals using the two-channel DPHY physical layer standard. This flexible configuration method enables the circuit to adapt to the data transmission requirements of different types of connectors.

[0054] First connector 1, serving as the circuit's input interface, connects to deserializer chip 3. Its primary function is to receive surround view data from the intelligent driving module and transmit this data to deserializer chip 3 for processing. After receiving the surround view data, deserializer chip 3 transmits the data to adapter board 2 by outputting MIPI interface signals using the corresponding DPHY physical layer standard, according to configuration instructions from system-level chip 4. Specifically, when second connector 6 is a single-lane connector 601, deserializer chip 3 outputs MIPI interface signals using one, four-lane DPHY physical layer standard (i.e., 4Lane DPHY*1). When second connector 6 is a dual-lane connector 602, deserializer chip 3 outputs MIPI interface signals using two, two-lane DPHY physical layer standards (i.e., 2Lane DPHY*2).

[0055] After receiving the surround view data from the deserializer chip 3, the adapter board 2 further converts the surround view data into a format and transmits it through the serializer chip 5 according to the type of the second connector 6. Specifically, Figure 2 As shown, when the second connector 6 is a single-channel connector 601, the adapter board 2 uses a serializer chip 5 to convert the surround view data into a single 12Gbps GMSL format signal (i.e., GMSL*1 12Gbps), and outputs it to the cockpit module through the second connector 6. When the second connector 6 is a dual-channel connector 602, the adapter board 2 uses two serializer chips 5 to convert the surround view data into two 6Gbps GMSL format signals (i.e., GMSL*1 6Gbps), and also outputs them to the cockpit module through the second connector 6. This design allows the circuit to flexibly adjust the signal format and transmission method based on different connector types and transmission requirements.

[0056] The output matching circuit design proposed in this embodiment accurately identifies the type of the second connector 6 through the system-level chip 4, and flexibly configures the output mode of the deserializer chip 3 according to the type of connector, thereby effectively adapting to two different data link solutions: single-channel 12Gbps and dual-channel 6Gbps. This design not only significantly improves the flexibility and compatibility of the system, enabling the circuit to adapt to changes in different types of connectors and data transmission requirements, but also ensures the accurate and stable transmission of surround view data under different link conditions. At the same time, through the collaborative work of the adapter board 2 and the serializer chip 5, the surround view data is converted into a signal format suitable for transmission on different links, further enhancing the reliability and stability of the system. In addition, the solution also simplifies the hardware design, reduces the complexity and cost of the system, and provides a more efficient and reliable solution for the development and application of intelligent driving systems. This solution not only improves the safety and convenience of driving, but also lays a solid foundation for the further development and promotion of intelligent driving technology.

[0057] Please refer again Figure 1 In one embodiment of the present invention, the connection between adapter board 2 and SoC 4 utilizes a specific port configuration. Specifically, adapter board 2 establishes an electrical connection with SoC 4 via its PIN#1 port. This connection provides a key signal path for subsequent identification of the type of second connector 6.

[0058] As the core control unit in the circuit, the system-on-chip 4 is responsible for identifying the type of the second connector 6. It accurately determines the specific type of the second connector 6 by monitoring the electrical level of the PIN#1 port on the adapter board 2. The specific identification logic is as follows:

[0059] When the PIN#1 port of the adapter board 2 is in a high-level state, the system-level chip 4 identifies the second connector 6 as a dual-channel connector 602 based on this level signal. At this time, the system-level chip 4 will configure the output mode of the deserializer chip 3 accordingly to meet the data transmission requirements of the dual-channel connector 602. Specifically, the deserializer chip 3 is configured to output MIPI interface signals using the two-channel DPHY physical layer standard.

[0060] Conversely, when PIN#1 of the adapter board 2 is in a low-level state, the SoC 4 identifies the second connector 6 as a single-channel connector 601. Based on this identification result, the SoC 4 also adjusts the configuration of the deserializer chip 3 to meet the data transmission requirements of the single-channel connector 601. Specifically, the deserializer chip 3 is configured to output MIPI interface signals using the four-channel DPHY physical layer standard.

[0061] This identification method, based on the high and low levels of PIN #1, not only enables rapid and accurate determination of the type of second connector 6 but also provides a reliable basis for flexible configuration of subsequent circuits and data transmission. Through the intelligent identification and configuration capabilities of the system-on-chip 4, the output matching circuit of this embodiment can adapt to the data transmission requirements of different connector types, significantly enhancing the system's flexibility and compatibility. This design also ensures accurate and stable transmission of surround view data under various link conditions, providing a strong guarantee for the safe and reliable operation of the intelligent driving system.

[0062] Please refer again Figure 1 In one implementation of this embodiment, the output matching circuits of different data links include not only core components such as the first connector 1, the adapter board 2, the deserializer chip 3, the system-level chip 4, the serializer chip 5, and the second connector 6, but also additionally include a second resistor R2 and a first resistor R1 to optimize the signal transmission and recognition performance of the circuit.

[0063] Specifically, second resistor R2 is connected in series between PIN#1 of adapter board 2 and SoC 4. This design primarily serves as a current-limiting resistor, preventing damage to SoC 4 or adapter board 2 caused by excessive current during signal transmission. Second resistor R2 also provides signal filtering, reducing noise interference during signal transmission and improving signal stability.

[0064] One end of the first resistor R1 is connected to a voltage source, and the other end is connected between PIN#1 of adapter board 2 and the second resistor R2. The first resistor R1 acts as a pull-up resistor. When PIN#1 of adapter board 2 is not actively driven (i.e., in a high-impedance state), the first resistor R1 pulls the voltage level of PIN#1 up to the voltage source level, ensuring that the system-on-chip 4 receives a clear high-level signal. This design avoids the voltage uncertainty caused by leaving the port floating, improving the reliability and stability of the circuit.

[0065] In actual applications, when the PIN#1 port of the adapter board 2 outputs a corresponding level signal based on the type of the second connector 6, the second resistor R2 and the first resistor R1 work together to ensure that the signal can be accurately and stably transmitted to the system-level chip 4. The system-level chip 4 accurately identifies the type of the second connector 6 based on the received level signal and configures the deserializer chip 3 accordingly to achieve flexible matching and efficient transmission of different data links.

[0066] In summary, by adding the second resistor R2 and the first resistor R1 , the output matching circuit of this embodiment is significantly improved in terms of signal transmission and recognition performance.

[0067] In one implementation of this embodiment, the system-on-chip 4 is connected to the deserializer chip 3 via an I2C communication interface.

[0068] As a serial communication bus standard widely used in the field of electronic systems and with mature technology, the I2C communication interface occupies an important position in the design of various complex embedded systems with its simple hardware connection method, efficient communication efficiency and excellent multi-device compatibility.

[0069] Specifically, the SoC 4 has dedicated pins for I2C communication. These pins establish a stable and reliable electrical connection with the corresponding I2C pins on the deserializer chip 3 through carefully designed printed circuit board routing. This physical connection establishes an efficient data transmission and control channel between the SoC 4 and the deserializer chip 3.

[0070] During system operation, the SoC 4, as the master device, assumes core control and management responsibilities. Based on pre-programmed logic and real-time system status monitoring, it sends a series of carefully crafted control commands and data parameters to the deserializer chip 3 via the I2C communication interface. These commands and parameters cover key parameters such as the deserializer chip 3's output mode configuration, data rate setting, and signal gain adjustment, ensuring that the deserializer chip 3 accurately and efficiently deserializes received surround view data according to the overall system requirements.

[0071] As a slave device, deserializer chip 3 rapidly parses and executes commands and data sent by SoC 4 via the I2C communication interface. Based on the commands, it configures and adjusts its internal circuits and functional modules to accurately deserialize surround view data and feeds the processed data back to SoC 4 or other subsequent circuit modules in the appropriate format and state.

[0072] Through this close connection and efficient communication between the system-level chip 4 and the deserializer chip 3 based on the I2C communication interface, the output matching circuit of this embodiment not only realizes flexible and precise control of the deserializer chip 3, but also ensures the accurate transmission and processing of the surround view data within the system.

[0073] Please refer again Figure 1In one implementation of this embodiment, first connector 1 performs the critical tasks of data reception and preliminary processing. Specifically, after receiving surround view data from the intelligent driving module, first connector 1 performs format conversion and signal splitting based on pre-set signal processing rules and circuit design requirements. After processing, first connector 1 converts the surround view data into four signals compliant with the GMSL format (i.e., GMSL*4).

[0074] GMSL, a high-speed serial communication protocol, offers significant advantages such as high bandwidth, low latency, and strong anti-interference capabilities, meeting the stringent requirements for high-volume, high-speed data transmission in intelligent driving systems. The four GMSL-formatted signals generated by the first connector 1 each carry a portion of the surround view data, and remain independent and synchronized to ensure data integrity and accuracy.

[0075] Subsequently, first connector 1 stably and reliably transmits these four GMSL-formatted signals to deserializer chip 3 via corresponding electrical connections. After receiving these signals, deserializer chip 3 further deserializes them, extracts valid surround view data, and outputs the data in an appropriate format and rate to subsequent circuit modules based on the configuration instructions of system-level chip 4, thus completing the entire surround view data transmission and processing process.

[0076] The surround view data is converted and transmitted into four GMSL format signals through the first connector 1 . The output matching circuit of this embodiment improves the efficiency and stability of data transmission.

[0077] In one implementation of this embodiment, the deserializer chip 3 is connected to the adapter board 2 via an I2C communication interface.

[0078] In this circuit design, the deserializer chip 3 establishes an electrical connection with the corresponding I2C pins on the adapter board 2 via specific I2C pins, thereby establishing a stable and reliable communication link. Through this I2C communication interface, the deserializer chip 3 can exchange data with the adapter board 2 in a two-way manner, such as transmitting configuration parameters, status information, and control instructions. This ensures that the deserializer chip 3 can accurately deserialize the received surround view data according to system requirements and pass the processed data to the adapter board 2 in the appropriate format and parameters.

[0079] At the same time, the connection between the adapter board 2 and the serializer chip 5 is also based on the I2C communication interface. However, the number of connections between the adapter board 2 and the serializer chip 5 will vary depending on the type of the second connector 6. When the second connector 6 is a single-channel connector 601, the adapter board 2 establishes a connection with a serializer chip 5 through the I2C communication interface. In this configuration, the adapter board 2 receives the surround view data from the deserializer chip 3, and after necessary processing and format conversion, sends the corresponding control instructions and data information to the serializer chip 5 through the I2C communication interface. The serializer chip 5 converts the surround view data into a 12Gbps GMSL format signal based on the received instructions, and finally outputs it to the cockpit module through the second connector 6.

[0080] When the second connector 6 is a dual-channel connector 602, the adapter board 2 establishes a connection with the two deserializer chips 5 via the I2C communication interface. At this time, the adapter board 2 needs to perform more complex processing and distribution of the surround view data from the deserializer chip 3, and send corresponding configuration and control instructions to the two deserializer chips 5 through the I2C communication interface, so that the two deserializer chips 5 work together to convert the surround view data into two 6Gbps GMSL format signals, which are then output to the cockpit module through the second connector 6. This flexible connection method based on the I2C communication interface enables the circuit system to adaptively adjust the number of channels and signal format for data transmission according to different application scenarios and requirements, greatly improving the flexibility and compatibility of the system, while also ensuring the accurate and stable transmission of surround view data under different link conditions.

[0081] Although the terms "first connector" and "deserializer core" are frequently used in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
