[0029] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that the terms "first," "second," etc., used in this disclosure and the accompanying drawings 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 disclosure described herein can be implemented in orders other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this disclosure.

[0031] The following description, with reference to the accompanying drawings, outlines a data transmission method, apparatus, chip, electronic device, storage medium, and computer program product according to embodiments of the present disclosure.

[0032] Figure 1 This is a flowchart illustrating a data transmission method according to an exemplary embodiment, such as... Figure 1 As shown, the data transmission method of this disclosure includes the following steps.

[0033] S101, receive task information of the control task of the data transmission controller sent by the main processor; wherein, the task information is sent before the control task is completed, and the control task is used to control the data transmission controller to execute the data transmission task.

[0034] S102, continue executing the control task based on the task information.

[0035] It should be noted that the data transmission method of this embodiment is executed by a microcontroller. The data transmission method of this embodiment can be executed by the data transmission device of this embodiment, which can be configured in any microcontroller to execute the data transmission method of this embodiment.

[0036] The main processor, also known as a general-purpose processor, is a high-performance, fully functional processor designed to run complex operating systems and multitasking applications. It includes the main CPU, which has stronger computing power and a more complex architecture than a microprocessor, but also consumes more power and has higher system overhead.

[0037] A microprocessor, also called a microprocessor, is a processor composed of one or a few large-scale integrated circuits, such as a microCPU (Central Processing Unit). Compared with the main processor, it has advantages such as low power consumption and low system overhead.

[0038] In this embodiment of the disclosure, the processor controls the data transmission controller to perform data transmission tasks. However, during operation, in addition to controlling the data transmission controller, the processor also needs to perform operations such as interrupt response and thread scheduling, resulting in a large processor load and low data transmission efficiency. In addition, the processor has a high power consumption problem, which results in a large power consumption required for data transmission.

[0039] To address the aforementioned issues, this disclosure proposes a collaborative control mechanism. The microprocessor receives task information from the data transmission controller sent by the main processor and continues to execute the control task based on the task information. Thus, the main processor and the microprocessor can collaboratively execute the control task, which can significantly reduce the load on the main processor. In addition, the microprocessor, with its low power consumption and lightweight architecture, can significantly improve data transmission efficiency and significantly reduce the power consumption and system overhead required for data transmission.

[0040] In addition, the microprocessor can continue to execute control tasks based on task information, which means that control tasks can be automatically migrated from the main processor to the microprocessor without the user having to manually switch to the microprocessor to execute control tasks, thus optimizing the user experience.

[0041] like Figure 7 As shown, chip 700 includes a main processor 701, a microprocessor 702, and a data transfer controller 703. This solution can significantly reduce the load on the main processor, thereby significantly reducing the performance requirements, power consumption, and system overhead of the main processor. The main processor can adopt a more lightweight architecture design, which helps to reduce chip area, increase chip integration, and reduce chip manufacturing costs.

[0042] It should be noted that the control task can include any step of the processor controlling the data transmission controller in related technologies. The control task is not overly limited; it may include data transmission controller initialization, triggering transmission startup, status monitoring and interrupt handling, and exception handling for the data transmission task. Initialization includes setting transmission parameters, configuring the operating mode, and enabling relevant peripherals and the clock. Triggering transmission startup includes writing a startup command to the control register of the data transmission controller. Status monitoring and interrupt handling includes periodically reading the status register of the data transmission controller, checking whether the transmission is complete, and handling interrupt requests sent by the data transmission controller. Exception handling for the data transmission task includes checking for transmission errors and, if errors are found, executing the exception handling procedure.

[0043] The task information for control tasks is not subject to many restrictions, but may include the execution progress of control tasks, executed steps, steps to be executed, the operation information of data transmission controllers, and the execution information of data transmission tasks.

[0044] There are no strict limitations on data transmission controllers, such as USB (Universal Serial Bus) controllers, network card controllers, PCIe (Peripheral Component Interconnect Express) controllers, etc.

[0045] In some possible implementations, before continuing to execute the control task based on the task information, the process further includes receiving a sixth instruction message sent by the main processor; wherein the sixth instruction message is used to instruct the microprocessor to continue executing the control task. Thus, the microprocessor only continues to execute the control task based on the task information after receiving the sixth instruction message sent by the main processor.

[0046] S103, update the task information and send the updated task information to the main processor; the updated task information is used by the main processor to continue executing the control task.

[0047] In this disclosure, the microprocessor can update the task information and send the updated task information to the main processor, so that the main processor can continue to execute the control task based on the updated task information, that is, the control task can be migrated from the microprocessor to the main processor.

[0048] In some possible implementations, after continuing to execute the control task based on the task information, a fifth instruction message is sent to the main processor; wherein the fifth instruction message is used to instruct the main processor to continue executing the control task. Thus, the microprocessor can notify the main processor to continue executing the control task.

[0049] It should be noted that this disclosure does not impose any restrictions on the execution sequence of steps S101-S103. Figure 1 The example only demonstrates the sequential execution of steps S101-S103. For instance, steps S101-S102 can be implemented as a standalone embodiment.

[0050] The data transmission method provided in the embodiments of this disclosure receives task information of a data transmission controller sent by a main processor. The task information is sent before the control task is completed. The control task is used to control the data transmission controller to execute the data transmission task. Based on the task information, the control task continues to be executed, the task information is updated, and the updated task information is sent to the main processor. The updated task information is used by the main processor to continue executing the control task. Therefore, this disclosure proposes a cooperative control mechanism whereby the microprocessor receives the task information of the data transmission controller sent by the main processor and continues to execute the control task based on the task information. This allows the main processor and the microprocessor to collaboratively execute the control task, significantly reducing the load on the main processor. Furthermore, the microprocessor, with its low-power, lightweight architecture, can significantly improve data transmission efficiency and significantly reduce the power consumption and system overhead required for data transmission.

[0051] In addition, the microprocessor can continue to execute control tasks based on task information, which means that control tasks can be automatically migrated from the main processor to the microprocessor without the user having to manually switch to the microprocessor to execute control tasks, thus optimizing the user experience.

[0052] In addition, the microprocessor can update the task information and send the updated task information to the main processor, so that the main processor can continue to execute the control task based on the updated task information, thus realizing the migration of the control task from the microprocessor to the main processor.

[0053] In addition, this solution can significantly reduce the load on the main processor, thereby significantly reducing the performance requirements, power consumption and system overhead of the main processor. The main processor can adopt a lighter architecture design, which helps to reduce chip area, increase chip integration and reduce chip manufacturing costs.

[0054] Figure 2 This is a flowchart illustrating a data transmission method according to another exemplary embodiment, such as... Figure 2 As shown, the data transmission method of this disclosure includes the following steps.

[0055] S201, receive task information of the control task of the data transmission controller sent by the main processor; wherein, the task information is sent before the control task is completed, and the control task is used to control the data transmission controller to execute the data transmission task.

[0056] The details of step S201 can be found in the above embodiments and will not be repeated here.

[0057] S202, based on task information, activate or disable the transmission function of the data transmission controller.

[0058] In some possible implementations, the transmission function of the data transmission controller is activated or disabled based on task information. This includes activating the data transmission controller's transmission function in response to task information indicating that the transmission link corresponding to the data transmission controller is in a connected state, and disabling the data transmission controller's transmission function in response to task information indicating that the transmission link corresponding to the data transmission controller is in a disconnected state. Thus, the data transmission controller's transmission function can be activated when the transmission link corresponding to the data transmission controller is in a connected state, and disabled when the transmission link corresponding to the data transmission controller is in a disconnected state.

[0059] In some possible implementations, activating or disabling the transmission function of the data transmission controller based on task information includes determining whether the transmission function of the data transmission controller meets activation or disabling conditions based on the task information; activating the transmission function of the data transmission controller in response to meeting the activation conditions; and disabling the transmission function of the data transmission controller in response to meeting the disabling conditions. Thus, the determination of whether the transmission function of the data transmission controller meets activation or disabling conditions can be taken into account with task information; the transmission function of the data transmission controller is activated when it meets the activation conditions, and disabled when it meets the disabling conditions.

[0060] It should be noted that activating or disabling the transmission function of the data transmission controller can be achieved using any data transmission controller control method in the relevant technology, without further limitations. For example, activating the transmission function of the data transmission controller includes enabling the endpoints, channels, or queues of the data transmission controller, while disabling the transmission function of the data transmission controller includes disabling the endpoints, channels, or queues of the data transmission controller.

[0061] S203, based on task information, allocates and reclaims target resources; where target resources are the resources required by the data transmission controller to execute data transmission tasks.

[0062] It should be noted that there are no excessive restrictions on the target resources, such as including descriptors and memory.

[0063] In some possible implementations, the target resources are allocated and reclaimed based on task information, including determining the resource allocation requirements of the data transmission controller based on the task information, and allocating the target resources to the data transmission controller based on the resource allocation requirements.

[0064] In some possible implementations, the allocation and reclamation of target resources are based on task information, including determining the resource reclamation requirements of the data transmission controller based on the task information, and reclaiming the target resources allocated to the data transmission controller based on the resource reclamation requirements.

[0065] S204, update the task information and send the updated task information to the main processor; the updated task information is used by the main processor to continue executing the control task.

[0066] The details of step S204 can be found in the above embodiments and will not be repeated here.

[0067] It should be noted that this disclosure does not impose any restrictions on the execution sequence of steps S201-S204. Figure 2The example only demonstrates the sequential execution of steps S201-S204. For instance, steps S201, S202, and S204 can be implemented as standalone embodiments, and steps S201, S203, and S204 can also be implemented as standalone embodiments.

[0068] The data transmission method provided in the embodiments of this disclosure activates or disables the transmission function of the data transmission controller based on task information, and / or allocates and reclaims target resources based on task information; wherein, the target resources are the resources required by the data transmission controller to perform data transmission tasks. Thus, the microprocessor can undertake the control tasks of activating or disabling the transmission function of the data transmission controller, and / or can undertake the control tasks of resource allocation and reclamation. These two types of control tasks typically occur frequently during data transmission. The main processor does not need to frequently handle these two types of control tasks, which can significantly reduce the load on the main processor, significantly improve data transmission efficiency, and significantly reduce the power consumption and system overhead required for data transmission.

[0069] Figure 3 This is a flowchart illustrating a data transmission method according to another exemplary embodiment, such as... Figure 3 As shown, the data transmission method of this disclosure includes the following steps.

[0070] S301 receives task information from the main processor regarding the control task of the data transmission controller; the task information is sent before the control task is completed, and the control task is used to control the data transmission controller to execute the data transmission task.

[0071] The details of step S301 can be found in the above embodiments and will not be repeated here.

[0072] S302, in response to the task information indicating that the transmission link corresponding to the data transmission controller is in a connected state, allocates target memory to the data transmission controller; wherein, the target memory is used by the data transmission controller for read and write operations.

[0073] It should be noted that allocating target memory to the data transmission controller can be achieved using any memory allocation method of the data transmission controller in the relevant technologies, and no further restrictions are imposed here.

[0074] In some possible implementations, the method further includes, in response to a data transmission task, using memory for storing data to be transmitted as target memory for a data transmission task; wherein the target memory is used by the data transmission controller to perform read operations to obtain the data to be transmitted.

[0075] In some possible implementations, the method further includes, in response to a data transmission task as a data receiving task, using memory for storing data to be received as target memory; wherein the target memory is used by the data transmission controller to perform write operations on the received data.

[0076] S303, Based on the description information of the data transmission task, generate a target descriptor; wherein, the target descriptor is used to indicate the description information.

[0077] S304, Write the target descriptor to the descriptor queue of the data transmission controller; wherein, the descriptor queue is used to store the descriptors to be read by the data transmission controller.

[0078] It should be noted that the target descriptor can be generated using any descriptor generation method in the relevant technologies, and no further restrictions are imposed here.

[0079] In some possible implementations, a target descriptor is generated based on the description information of the data transmission task, including filling idle descriptors with information based on the description information of the data transmission task to generate the target descriptor.

[0080] It should be noted that there are no excessive restrictions on the target descriptor or description information.

[0081] In some possible implementations, the descriptive information includes at least one of the following: The memory address of the target memory; The amount of data to be transmitted; The source address and destination address of the data to be transmitted.

[0082] S305, in response to the successful execution of the data transmission task, reclaims the target descriptor.

[0083] It should be noted that the target descriptor can be reclaimed using any descriptor reclamation method in the relevant technologies, and no particular limitation is made here. For example, the target descriptor can be marked as an idle descriptor, and / or the target descriptor can be written to an idle descriptor queue for reclamation.

[0084] S306, in response to the data transmission task being converted to a data sending task and the data transmission task being executed successfully, performs a reclaiming process on the target memory.

[0085] It is understandable that a data transmission task is a data sending task, and if the data transmission task is executed successfully, it means that the data to be sent has been retrieved from the target memory, and the target memory can then be reclaimed.

[0086] It should be noted that the target memory can be reclaimed using any memory reclamation method available in the relevant technologies; no particular limitation is made here. For example, the target memory can be marked as free memory for reclamation.

[0087] S307, in response to the data transmission task being a data receiving task, and the data transmission task being successfully executed, and the data received by the data transmission controller being retrieved from the target memory, the target memory is reclaimed.

[0088] It is understandable that the data transmission task is a data receiving task, and the data transmission task is executed successfully. The data received by the data transmission controller has been retrieved from the target memory, indicating that after the data received by the data transmission controller is successfully stored in the target memory, it is retrieved from the target memory by the data usage module, and the target memory can then be reclaimed.

[0089] In some possible implementations, the method further includes receiving first indication information sent by a data transmission controller, wherein the first indication information is used to indicate that the data transmission task was successfully executed.

[0090] In response to the first indication information indicating successful execution of the data receiving task, a second indication information is sent to the data usage module; wherein the second indication information indicates the memory address of the target memory so that the data usage module can perform a read operation on the target memory.

[0091] The receiving data module sends a third indication message; wherein the third indication message is used to indicate that the data using module has retrieved the data received by the data transmission controller from the target memory.

[0092] Therefore, the microprocessor can receive the first instruction information sent by the data transmission controller and determine that the data transmission task has been successfully executed based on the first instruction information.

[0093] When the first indication message indicates that the data receiving task has been successfully executed, the microprocessor sends a second indication message to the data usage module to inform the data usage module of the memory address of the target memory, so that the data usage module can read data from the target memory.

[0094] The microprocessor can receive third indication information sent by the data usage module and determine, based on the third indication information, that the data received by the data transmission controller has been retrieved from the target memory.

[0095] S308 updates the task information and sends the updated task information to the main processor; the updated task information is used by the main processor to continue executing the control task.

[0096] The details of step S308 can be found in the above embodiments and will not be repeated here.

[0097] It should be noted that this disclosure does not limit the execution sequence of steps S301-S308. For example, steps S301-S302 and S308 can be implemented as independent embodiments, steps S301-S303 and S308 can be implemented as independent embodiments, steps S301-S304 and S308 can be implemented as independent embodiments, steps S301-S305 and S308 can be implemented as independent embodiments, steps S301-S304, S306 and S308 can be implemented as independent embodiments, and steps S301-S304, S307 and S308 can be implemented as independent embodiments.

[0098] The data transmission method provided in the embodiments of this disclosure allocates target memory to the data transmission controller in response to task information indicating that the transmission link corresponding to the data transmission controller is in a connected state. The target memory is used by the data transmission controller for read and write operations. A target descriptor is generated based on the description information of the data transmission task. The target descriptor is used to indicate the description information and is written to the descriptor queue of the data transmission controller. The descriptor queue stores descriptors to be read by the data transmission controller. Therefore, when the transmission link corresponding to the data transmission controller is in a connected state, the microprocessor can allocate target memory to the data transmission controller, generate a target descriptor based on the description information of the data transmission task, and write the target descriptor to the descriptor queue of the data transmission controller.

[0099] Furthermore, in response to a successful data transfer task, the target descriptor is reclaimed; in response to a successful data transfer task (e.g., a data sending task), the target memory is reclaimed; and in response to a successful data transfer task (e.g., a data receiving task), the memory allocated to the data transfer controller is reclaimed after the data received by the data transfer controller has been retrieved from the target memory. Thus, after a successful data transfer task, the microprocessor can reclaim both the target descriptor and the target memory.

[0100] Figure 4 This is a flowchart illustrating a data transmission method according to another exemplary embodiment, such as... Figure 4 As shown, the data transmission method of this disclosure includes the following steps.

[0101] S401 receives task information from the main processor regarding the control task of the data transmission controller; wherein, the task information is sent before the control task is completed, and the control task is used to control the data transmission controller to execute the data transmission task.

[0102] The details of step S401 can be found in the above embodiments and will not be repeated here.

[0103] S402, in response to the task information indicating that the transmission link corresponding to the data transmission controller is disconnected, the target memory allocated to the data transmission controller is reclaimed; wherein, the target memory is used by the data transmission controller for read and write operations.

[0104] S403, perform the recycling process on the target descriptor; wherein, the target descriptor is used to indicate the description information of the data transmission task.

[0105] It should be noted that the relevant content on the recycling of target memory and target descriptors can be found in the above embodiments, and will not be repeated here.

[0106] S404, update the task information and send the updated task information to the main processor; the updated task information is used by the main processor to continue executing the control task.

[0107] The details of step S404 can be found in the above embodiments and will not be repeated here.

[0108] It should be noted that this disclosure does not impose any restrictions on the execution sequence of steps S401-S404. Figure 4 The example only demonstrates the execution of steps S401-S404 in sequence.

[0109] The data transmission method provided in the embodiments of this disclosure, in response to task information indicating that the transmission link corresponding to the data transmission controller is in a disconnected state, reclaims the target memory allocated to the data transmission controller; wherein the target memory is used by the data transmission controller for read and write operations, and the target descriptor is reclaimed; wherein the target descriptor is used to indicate the description information of the data transmission task. Thus, after the transmission link corresponding to the data transmission controller is in a disconnected state, the microprocessor can reclaim the target descriptor and the target memory.

[0110] Figure 5 This is a flowchart illustrating a data transmission method according to another exemplary embodiment, such as... Figure 5 As shown, the data transmission method of this disclosure includes the following steps.

[0111] S501, receive the fourth indication information sent by the data transmission controller; wherein the fourth indication information is used to indicate that an abnormality has occurred in the data transmission task.

[0112] S502, based on the fourth instruction information, performs exception handling on the data transmission task.

[0113] In this disclosure, the microprocessor can receive a fourth indication message sent by the data transmission controller, wherein the fourth indication message is used to indicate that an abnormality has occurred in the data transmission task, and performs abnormal handling on the data transmission task based on the fourth indication message. That is, the microprocessor can undertake the abnormal handling of the data transmission task. The abnormal handling of the data transmission task usually involves complex processing logic, which can significantly reduce the load on the main processor, significantly improve the data transmission efficiency, and significantly reduce the power consumption and system overhead required for data transmission.

[0114] It should be noted that exception handling for data transmission tasks can be achieved using any of the exception handling methods for data transmission tasks in the relevant technologies.

[0115] In some possible implementations, the data transmission task is handled abnormally based on the fourth indication information, including determining abnormal information of the data transmission task based on the fourth indication information, and handling the data transmission task abnormally based on the abnormal information of the data transmission task.

[0116] In some possible implementations, the abnormal information of the data transmission task is used to perform abnormal handling on the data transmission task. This includes determining the cause of the abnormality of the data transmission task based on the abnormal information, determining the abnormal handling process of the data transmission task based on the cause of the abnormality, and executing the abnormal handling process of the data transmission task to perform abnormal handling on the data transmission task.
