Technical Field

[0001] This application relates to the field of communication technology, and more particularly to the field of embedded application software development technology for autonomous driving, specifically to a software deployment method, apparatus, device, and storage medium. Background Technology

[0002] With the development of autonomous driving technology, the requirements for system-on-chip (SoC) are becoming increasingly stringent in terms of software deployment, development complexity, and precision. Typically, software systems are automatically loaded by fixed logic after the underlying hardware boots up, making changes and upgrades inflexible and costly.

[0003] In practical applications, the various software systems in autonomous driving technology have different functions and corresponding requirements. For example, the control module requires high real-time performance, while the data analysis module requires significant computing resources. Therefore, how to flexibly deploy multiple software systems within a single SoC to enable each system to be applied in specific scenarios is a problem that needs to be solved during the development process. Summary of the Invention

[0004] This application provides a software deployment method, apparatus, device, and storage medium to at least solve the technical problem of mismatch between software system deployment and requirements in related technologies. The technical solution of this application is as follows:

[0005] According to a first aspect of this application, a software deployment method is provided, applied to a multi-core processor, wherein the multi-core processor includes multiple system cores of different core types. The method includes: obtaining the functional type of a target software system; determining a target core type corresponding to the target software system based on the functional type; the target core type being any one of multiple core types; and deploying the target software system on a system core of the target core type.

[0006] Based on the above technical means, this application can determine the system core in a multi-core processor to deploy the target software system based on the functional type of the target software system, so that each system core can adapt to the corresponding functional requirements and realize the flexible deployment of multiple software systems on a multi-core processor.

[0007] In one possible implementation, the multiple core types include large cores and small cores; the method for determining the target core type corresponding to the target software system based on the function type includes: when the function type indicates that the resource consumption of the target software system is greater than a preset value, the target core type is determined to be a large core; when the function type indicates that the response time of the target software system is less than a preset time, the target core type is determined to be a small core.

[0008] Based on the aforementioned technical methods, large cores have a larger processing capacity, correspondingly consuming more computing power and memory resources. Conversely, small cores have a smaller processing capacity but faster processing speed. Therefore, this application can match the corresponding core type to the target software system based on resource consumption and response time, so that the system core can adapt to the corresponding functional requirements.

[0009] In one possible implementation, the method further includes: obtaining target configuration information of the application process of the target software system; scheduling the shared resources of the multi-core processor and running the application process according to the target configuration information.

[0010] Based on the above technical means, this application can schedule shared resources of multi-core processors, and avoid the resource copying process when running application processes, thereby reducing copying time and improving the efficiency of resource scheduling.

[0016] Based on the aforementioned technical means, this application can determine an adjustment strategy for the quantity of shared resources based on whether the occupied resources exceed a preset normal range, so as to adjust the quantity of shared resources according to the adjustment strategy, thereby automatically and quickly realizing the dynamic adjustment of shared resources.

[0017] In one possible implementation, the communication channels of the multi-core processor include a primary channel and a backup channel; the method further includes: transmitting data through the primary channel and obtaining transmission status information; when the transmission status information indicates that the primary channel transmission is abnormal, switching to the backup channel to transmit data.

[0018] Based on the above technical means, this application can switch to a backup channel for transmission when the primary channel is abnormal, without affecting the continuity of data transmission, thereby improving the user experience.

[0020] In one possible implementation, the multiple core types include large cores and small cores; the aforementioned processing unit is specifically used to determine the target core type as a large core when the resource consumption corresponding to the target software system represented by the function type is greater than a preset value; and to determine the target core type as a small core when the response time corresponding to the target software system represented by the function type is less than a preset time.

[0049] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0050] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. 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.

[0051] For ease of understanding, the software deployment method provided in this application will be described in detail below with reference to the accompanying drawings.

[0052] Figure 1 This is a flowchart illustrating a software deployment method according to an exemplary embodiment, such as... Figure 1 As shown, the software deployment method includes the following steps:

[0053] S101, Multi-core processor obtains the function type of the target software system.

[0054] Optionally, the function type can include logic control type and pure algorithm type.

[0055] Pure algorithm-based software systems include applications with high computational requirements, such as environmental perception, visual perception, sensor fusion, and planning and decision-making. They also include applications with high memory requirements, such as data logging, diagnostics, sensors, and internal communication.

[0056] Pure algorithm-based software systems include applications with high real-time requirements, such as external communication, security management, real-time control, and redundant communication.

[0057] In one possible approach, the method for obtaining the function type of a target software system on a multi-core processor may include: when the target software system is initially deployed on a multi-core processor, the developers may manually identify and input the function type of the target software system.

[0058] S102. The multi-core processor determines the target core type corresponding to the target software system based on the function type.

[0059] A multi-core processor includes system cores of multiple core types, and the target core type can be any one of the multiple core types.

[0060] Optionally, multiple kernel types are available, including big kernels and little kernels.

[0061] S103, a multi-core processor, deploys the target software system on the target core type system core.

[0062] In some embodiments, in order to determine the target core type corresponding to the target software system, the method for determining the target core type corresponding to the target software system based on the function type in S102 provided in this application embodiment specifically includes the following steps:

[0063] S201. When the resource consumption corresponding to the target software system is greater than the preset value, the multi-core processor determines the target core type as a large core.

[0064] S202. When the function type indicates that the response time of the target software system is less than the preset time, the multi-core processor determines the target core type as a small core.

[0065] Among them, the large cores have a larger processing capacity, which corresponds to a greater consumption of computing power and memory resources, while the small cores have a smaller processing capacity but a faster processing speed.

[0066] Therefore, applications with high real-time requirements can be deployed on small cores, while applications with high computing power and memory requirements can be deployed on large cores.

[0067] For example, such as Figure 2As shown, the software system deployed by the multi-core processor includes visual perception 1, sensor 2, environmental perception 3, vehicle signal 4, sensor fusion 5, planning and decision 6, data logging 7, diagnostics 8, status management 9, and internal communication 10, deployed on two large cores. It also includes external communication 11, safety management 12, real-time control 13, and redundant communication 14, deployed on four small cores respectively.

[0068] Visual perception 1 is used to capture images of the vehicle's front view, panoramic view, and surrounding view.

[0069] Sensor 2 includes lidar, microwave radar, and front and rear angle radar.

[0070] Environmental perception 3 is used to collect data on vehicle interior and exterior temperatures, weather conditions, and targets around the vehicle.

[0071] Vehicle signal 4 indicates the vehicle body signal.

[0072] Sensor fusion 5 is used to integrate and analyze the local data resources provided by visual perception 1, sensor 2 and environmental perception 3.

[0073] Planning and Decision 6 is used to realize lateral and longitudinal control planning and decision-making, automatic driving and automatic parking path planning and decision-making, vehicle on-ramps and off-ramps planning and decision-making, parking space planning and decision-making, etc.

[0074] Data record 7 is used to record the data generated in each scenario and its communication and data transmission with the cloud platform.

[0075] Diagnostics 8 includes diagnostic messages for customers, and diagnostics for development, debugging, and maintenance.

[0076] Status Management 9 is used to manage and schedule various states of the vehicle.

[0077] Internal communication 10 includes electronic fences and communication between large and small core chips.

[0078] External communication 11 includes high, medium and low level controller area network (CAN) bus, vehicle Ethernet communication, and wireless communication.

[0079] Security Management 12 is used to implement information security management, irreversible fault management, and fault data recording management.

[0080] Real-time control 13 includes lateral and longitudinal control, vehicle control, and safety braking.

[0081] Redundant communication 14 is used to switch between primary and backup channels.

[0082] In some embodiments, in order to enable the target software system to run normally on a multi-core processor, the method provided in this application embodiment further includes the following steps:

[0083] S301, the multi-core processor obtains the target configuration information of the application process of the target software system.

[0084] S302: The multi-core processor schedules the shared resources of the multi-core processor and runs application processes according to the target configuration information.

[0085] Optionally, shared resources may include memory and computing resources.

[0086] like Figure 3 As shown, based on the commonalities of multiple application processes 01, shared resources 02 can be pre-configured for use by application processes of multiple software systems. Furthermore, to resolve the conflict and contention issues among multiple application processes 01, this application embodiment provides unified resource management 03 to address these issues.

[0087] In one feasible approach, pure algorithm programs can utilize the hardware acceleration provided by the SOC, using the interfaces provided by neon technology to perform addition, subtraction, multiplication, and division, while supplementing with matrix operations to reduce resource consumption. This, combined with the flexible deployment of the target software system, achieves the effect of rational resource utilization.

[0088] In some embodiments, in order to obtain target configuration information of the application process of the target software system, such as Figure 4 As shown, the method for a multi-core processor to obtain target configuration information of the application process of the target software system in S301 provided in this application embodiment specifically includes the following steps:

[0089] S401: The multi-core processor runs the application process based on the initial configuration information preset by the application process and obtains the running information of the application process at the running time.

[0090] S402. When the runtime information indicates that the application process is running abnormally, the multi-core processor determines the target exception type of the application process based on the runtime information.

[0091] Optionally, the target anomaly type can include multiple levels, represented by pre-created corresponding identifiers.

[0092] For example, as shown in Table 1, the target anomaly type can include five anomaly types: application logic failure, radar sensor failure, vision sensor failure, communication failure, and domain controller failure. The anomaly type identifier can be represented as a 32-bit wide classification code, with each classification code representing one anomaly type. As shown in Table 2, each anomaly type includes specific fault content, which can be represented as a 16-bit wide fault code.

[0093] Table 1 Classification Codes

[0094] Table 2 Fault Codes

[0095]

[0096]

[0097] During the design phase, the correspondence between classification codes and exception types, as well as the correspondence between fault codes and fault content, for each software system is incorporated into the source code. When a runtime exception occurs, the classification code is written into the process along with the fault code, facilitating the identification of exception types and fault content by debugging personnel. This application does not limit the format and bit width of the classification codes and fault codes; Tables 1 and 2 are merely illustrative examples. This application also does not limit the format of the codes written into the process; Table 1 uses a txt format as an example.

[0098] S403, the multi-core processor sends an exception notification message to the debugging terminal.

[0099] The exception notification message includes: runtime information and the target exception type.

[0100] In one feasible approach, developers can instruct the debugging terminal to subscribe to exception notification messages by inputting configuration items via the vehicle's infotainment display, mobile application, or cloud platform. When the debugging terminal receives an exception notification message, it can authenticate the object viewing the message. If the object is an authorized user, the debugging terminal can display the exception notification message.

[0101] In one feasible approach, administrators can grant different levels of permissions to objects, allowing them to view and respond to different message contents. Administrators can configure these permissions; by default, only basic permissions are granted.

[0102] The S404 multi-core processor receives the configuration update message sent by the debug terminal in response to the exception notification message.

[0103] Configuration update messages are used to indicate that the initial configuration information has been updated.

[0104] In one feasible approach, the debugging terminal can determine the target exception type of the application process based on runtime information. The debugging terminal can then determine the target handling strategy corresponding to the target exception type based on a pre-defined mapping between exception types and handling strategies, and finally generate a configuration update message based on the target handling strategy.

[0105] In some embodiments, in order to archive runtime data during abnormal runtime events, such as Figure 4 As shown, the method provided in this application embodiment further includes the following steps:

[0106] S405. When the running information indicates that the application process is running abnormally at runtime, the multi-core processor obtains a set of running information of the application process within a preset time period.

[0107] The preset time period includes the running time, such as the time period within 30 seconds before and after the running time.

[0108] The S406 multi-core processor stores a set of runtime information in non-volatile memory.

[0109] Specifically, in combination Figure 5 The process of debugging configuration information is described. After the multi-core processor obtains the debugging information of the application process, it can read the application process's configuration file to determine the debugging parameters to be debugged. Then, the application process is loaded and run according to the initial configuration information of the debugging parameters.

[0110] When an application process fails to start normally, a multi-core processor can send an error message and close the application process's launcher.

[0111] If the application process starts normally and there are no irreversible or functional failures, the application process will continue to run.

[0112] When an application process experiences an irreversible or functionally impactful failure, the multi-core processor acquires a set of runtime information for the application process within a 30-second period before and after the current runtime and stores it in non-volatile memory. Simultaneously, it sends an exception notification message to the debugging terminal so that the terminal can display the notification.

[0113] In some embodiments, in order to achieve dynamic adjustment of the capacity of shared resources, the method provided in this application further includes the following steps:

[0114] S501. When the occupied resources of the shared resources exceed the preset normal range, the multi-core processor updates the initial resource quantity of the shared resources to the target resource quantity.

[0115] S502. When the occupied resources are restored to the normal range, the multi-core processor updates the target resource quantity to the initial resource quantity.

[0116] In one possible implementation, Resource Management 03 can provide resource alerts. If the occupied resources of shared resources exceed the preset normal range, for example, if the remaining shared resources are less than 20%, and depending on the program's running status, such as in automatic parking or automatic driving, Resource Management 03 will temporarily update the initial resource quantity of shared resources to the target resource quantity to solve the problem of resource shortage during full-speed operation and ensure the normal operation of all application processes.

[0117] When the occupied resources are within a normal range, some memory reclamation mechanisms can meet the requirements for normal operation, so the initial resource quantity of shared resources is not updated.

[0118] In some embodiments, the communication channels of a multi-core processor include a primary channel and a backup channel. The method provided in this application embodiment further includes the following steps:

[0119] The S601 multi-core processor transmits data through the primary channel and obtains transmission status information.

[0120] Optionally, transmission status information includes transmission delay, packet loss rate, transmission rate, etc.

[0121] In one possible approach, data is transmitted using a fixed frame format, and cyclic redundancy check (CRC32) is used to verify the data. Alternatively, a binary data encryption method based on 64 printable characters (BASE64) can be used to improve data security.

[0122] S602. When the transmission status information indicates that the primary channel transmission is abnormal, the multi-core processor switches to the backup channel to transmit data.

[0123] Specifically, multi-core processor communication adopts a redundant design pattern, including a primary channel and a backup channel.

[0124] Combination Figure 6 The SoC chip 001 transmits data through the Ethernet switch chip 002, the primary port 003, and the backup port 004. The SoC chip 001 establishes a primary channel and a backup channel with the Ethernet switch chip 002 through two network ports. The primary port 003 and the backup port 004 correspond to the primary channel and the backup channel, respectively.

[0125] When the primary channel is operating normally, the backup channel can communicate additional non-essential services. When transmission status information indicates an anomaly in the primary channel transmission, for example, if three frames of data loss are detected, the SoC chip 001 generates a fault notification. The Ethernet switch chip 002, within a switching period after receiving the primary channel fault notification (e.g., within 20 milliseconds), switches to the backup channel to transmit data. Once the faulty channel is repaired, the Ethernet switch chip 002 switches back to the primary channel within a preset time (e.g., after one minute).

[0126] In one possible implementation, the multi-core processor can also notify the visual interface, cloud platform, and mobile device of the current communication channel type.
