Technical Field

[0001] This application relates to the field of computer technology, and more specifically, to a task data processing method, apparatus, and electronic device. Background Technology

[0002] In related approaches, artificial intelligence tasks typically require the use of pipelined structures to process data. For example, when a Neural Network Processing Unit (NPU) executes an algorithm to process an image, it generally first needs to preprocess the image, then input the processed image into the NPU for further processing, and finally input the processed image into the display module for display.

[0003] However, there are still issues with data processing anomalies in the relevant task data processing methods. For example, when a task is interrupted during execution, the data corresponding to the task has not yet been processed and accumulates in the pipeline structure, causing anomalies in the data processing of subsequent tasks in the pipeline. Summary of the Invention

[0004] In view of the above problems, this application proposes a task data processing method, apparatus, electronic device, and computer program product to improve the above problems.

[0005] In a first aspect, this application provides a task data processing method applied to an electronic device. The electronic device includes a first data processing module, a second data processing module, a first data buffer module, and a second data buffer module. The first data buffer module stores data output by the first data processing module. The second data processing module reads data from the first data buffer module during task execution, processes it, and outputs the processed data to the second data buffer module. The electronic device also includes a first mailbox module for communication between the first data processing module and the second data processing module. The method includes: the second data processing module responding to a received interrupt signal to obtain the content of the received interrupt signal; if the content of the interrupt signal indicates termination of the current task and commencement of the next task, clearing the task data corresponding to the current task in the first data buffer module and the second data processing module, and clearing the task data corresponding to the current task in the second data buffer module; if the content of the interrupt signal indicates pause of the current task and commencement of the next task, storing task status data corresponding to the current task, which is used by the second data processing module to resume execution of the current task after completing the next task; and executing the next task corresponding to the interrupt signal.

[0006] Secondly, this application provides a task data processing device operating in an electronic device. The electronic device includes a first data processing module, a second data processing module, a first data buffer module, and a second data buffer module. The first data buffer module stores data output by the first data processing module. The second data processing module reads data from the first data buffer module during task execution, processes it, and outputs the processed data to the second data buffer module. The electronic device also includes a first mailbox module for communication between the first and second data processing modules. The device includes an interrupt signal content acquisition unit, used by the second data processing module in response to a received interrupt signal. The system includes: a current task data cleanup unit, configured to clean up the task data corresponding to the current task in the first data buffer module and the second data processing module, and clean up the task data corresponding to the current task in the second data buffer module, if the content of the interrupt signal indicates termination of the current task and commencement of the next task; a current task status data storage unit, configured to store the task status data corresponding to the current task, if the content of the interrupt signal indicates termination of the current task and commencement of the next task, and the task status data is used to resume execution of the current task after the second data processing module has completed the execution of the next task; and a next task execution unit, configured to execute the next task corresponding to the interrupt signal.

[0007] Thirdly, this application provides an electronic device, including a first data processing module, a second data processing module, a first data buffer module, a second data buffer module, a first mailbox module, and a memory. The first data buffer module is used to store data output by the first data processing module. The second data processing module is used to read data from the first data buffer module for processing during task execution and output the processed data to the second data buffer module. The first mailbox module is used for communication between the first data processing module and the second data processing module.

[0009] Fifthly, this application provides a computer-readable storage medium storing program code, wherein the above-described method is executed when the program code is run.

[0010] This application provides a task data processing method, apparatus, electronic device, computer program product, and storage medium. In response to a received interrupt signal, the second data processing module acquires the content of the received interrupt signal. If the interrupt signal indicates termination of the current task and commencement of the next task, the module clears the task data corresponding to the current task in both the first and second data processing modules, and also clears the task data corresponding to the current task in the second data buffer module. If the interrupt signal indicates pause of the current task and commencement of the next task, the module stores the task status data corresponding to the current task. This task status data is used by the second data processing module to resume execution of the current task and the next task corresponding to the interrupt signal after the second data processing module has completed the next task. This method allows for the clearing or storage of task status data corresponding to the current task based on the interrupt signal, avoiding data processing anomalies when the electronic device executes the next task corresponding to the interrupt signal.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] In related approaches, artificial intelligence tasks typically require the use of pipelined structures to process task data. For example, when a Neural Network Processing Unit (NPU) executes an algorithm to process an image, it generally first needs to preprocess the image, then input the processed image into the NPU for further processing, and finally input the processed image into the display module for display.

[0023] The inventors discovered in their research that there are still data processing anomalies in the relevant task data processing methods. For example, when a task is interrupted during execution, the data corresponding to the task has not yet been processed and accumulates in the pipeline structure, causing anomalies in the subsequent task data processing in the pipeline.

[0024] Therefore, the inventors have proposed a task data processing method, apparatus, electronic device, and computer program product in this application. After the second data processing module responds to a received interrupt signal and obtains the content of the received interrupt signal, if the content of the interrupt signal indicates termination of the current task and commencement of the next task, the task data corresponding to the current task in the first data buffer module and the second data processing module is cleared, as is the task data corresponding to the current task in the second data buffer module. If the content of the interrupt signal indicates pause of the current task and commencement of the next task, the task status data corresponding to the current task is stored. This task status data is used by the second data processing module to resume execution of the current task and execute the next task corresponding to the interrupt signal after the second data processing module has completed the execution of the next task. This method allows for the clearing or storage of task status data corresponding to the current task based on the interrupt signal, avoiding data processing anomalies when the electronic device executes the next task corresponding to the interrupt signal.

[0025] Please see Figure 1 This application provides a task data processing method applied to an electronic device. The electronic device includes a first data processing module, a second data processing module, a first data buffer module, and a second data buffer module. The first data buffer module stores data output by the first data processing module. The second data processing module reads data from the first data buffer module during task execution, processes it, and outputs the processed data to the second data buffer module. The electronic device also includes a first mailbox module for communication between the first data processing module and the second data processing module. The method includes:

[0026] S110: The second data processing module responds to the received interrupt signal and obtains the content of the received interrupt signal.

[0027] In this embodiment, the second data processing module is a module capable of performing data calculation and image data processing. More specifically, the second data processing module can be a chip with data calculation and image processing functions, such as an NPU or a DSP (Digital Signal Processing).

[0028] In one approach, the central control module (e.g., MCU (Microcontroller Unit), CPU (Central Processing Unit)) may respond to an interrupt request from other functional modules in the electronic device (e.g., telephone communication module, voice receiving module, etc.) by sending an interrupt signal to the second data processing module. This interrupt request can indicate that other functional modules require the second data processing module to process the task data corresponding to that functional module.

[0029] As another approach, it could be an interrupt signal sent directly from other functional modules in the electronic device (e.g., telephone communication module, voice receiving module, etc.) to the second data processing module.

[0030] Furthermore, in the embodiments of this application, the content of the interrupt signal can be to terminate the task being executed by the second data processing module and start executing the next task, or to pause the task being executed by the second data processing module and start executing the next task.

[0031] One approach is to determine the content of the interrupt signal based on the application scenario. For example, when the second data processing module is performing a video processing task, and the telephone communication function module needs the second data processing module to process telephone-related task data, the telephone communication function module can directly send an interrupt signal to the second data processing module indicating the termination of the video processing task and the execution of the telephone processing task. Alternatively, the telephone communication function module can send an interrupt request to the central control module, indicating that the telephone communication function module needs the second data processing module to process telephone-related task data. In response to this interrupt request, the central control module can send an interrupt signal to the second data processing module indicating the termination of the video processing task and the execution of the telephone processing task.

[0032] For example, when the second data processing module is performing a music playback task, the voice receiving module needs the second data processing module to process voice-related task data. In this case, the voice receiving module can directly send an interrupt signal to the second data processing module, indicating that the music playback task is paused and the voice receiving task is executed. Alternatively, the voice receiving module can send an interrupt request to the central control module. This request indicates that the voice receiving module needs the second data processing module to process voice-related task data. In response to this interrupt request, the central control module can send an interrupt signal to the second data processing module, indicating that the music playback task is paused and the voice receiving task is executed.

[0033] S120: If the content of the interrupt signal indicates that the current task is terminated and the next task is started, clear the task data corresponding to the current task in the first data buffer module and the second data processing module, and clear the task data corresponding to the current task in the second data buffer module.

[0034] Among them, as a method, such as Figure 2 As shown, clearing the task data corresponding to the current task in the first data buffer module and the second data processing module includes:

[0035] S121: Clear the task data corresponding to the current task in the second data processing module by using a reset signal.

[0036] In one approach, when the second data processing module responds to an interrupt signal sent by the central control module or other functional modules of the electronic device, which indicates the termination of the current task and the start of the next task, the central control module can send a reset signal to the second data processing module, thereby clearing the task data corresponding to the current task in the second data processing module.

[0037] S122: Send a first signal to the first mailbox module. The first signal is used to notify the first data processing module that the task data corresponding to the current task in the first data buffer module is in a cleanable state.

[0038] In this embodiment, the first mailbox module is a communication module that enables communication between different modules. More specifically, the first mailbox module can be a module that communicates between the first data processing module and the second data processing module, such as a mailbox communication (MAILBOX) module. The first data processing module can be a module for data preprocessing, for example, the first data processing module can perform image resizing, translation, rotation, and other processing.

[0039] Optionally, data that needs to be preprocessed can be input to the first data processing module via DMA (Direct Memory Access).

[0040] In one approach, the second data processing module can send a first signal to the first mailbox module to clear the task data corresponding to the current task in the first data buffer module. This first signal can be used to notify the first data processing module via the first mailbox module that the task data corresponding to the current task in the first data buffer module is in a cleanable state. The first signal can include a fake read signal and a read completion signal. The fake read signal can be used to start a fake read thread, and the read completion signal can be used to indicate that the second data processing module has finished reading the task data corresponding to the current task from the first data buffer module.

[0041] More specifically, such as Figure 3 As shown, when it is necessary to clean up the task data corresponding to the current task in the first data buffer module, the second data processing module can first send a fake read signal to the first mailbox module to indicate that the "fake read" thread has been started, and then send a read completion signal (such as a csync signal) to the first mailbox module through the "fake read" thread. The read completion signal indicates that the second data processing module has finished reading the task data corresponding to the current task in the first data buffer module, but in fact, the second data processing module has not performed the operation of reading the task data corresponding to the current task in the first data buffer module. When MAILBOX receives the fake read signal and the read completion signal (such as a csync signal) in succession, it can increase the available storage space of the current first data buffer module. The increased available storage space is exactly the same as the storage space required for the task data corresponding to the current task. This allows the data output by the first data processing module corresponding to the next task to overwrite the task data corresponding to the current task in the first data buffer module during the execution of the next task, thereby realizing the cleanup of the task data corresponding to the current task in the first data buffer module.

[0042] Furthermore, in this embodiment, the electronic device also includes a data output module and a second mailbox module. The second mailbox module is a communication module that enables communication between different modules. More specifically, the second mailbox module can be a module that communicates between the second data processing module and the data output module, such as a mailbox communication (MAILBOX) module. The data output module can be used to read data from the second data buffer module and output it. More specifically, the data output module can be a display module, etc., wherein the display module can be used to display the image processed by the second data processing module.

[0043] Optionally, in this embodiment of the application, there are multiple ways to clear the task data corresponding to the current task in the second data buffer module.

[0044] In one approach, the first communication module can send a write completion signal to the data output module to clear the task data corresponding to the current task in the second data buffer module. This write completion signal can be used to trigger the data output module to read the task data corresponding to the current task in the second data buffer module, and to supplement the read task data before outputting it.

[0045] Optionally, the first communication module can be a signal line for connecting the second data processing module and the data output module. For example, such as... Figure 4 As shown, the second data processing module can send a write completion signal to the data output module via signal line 1. This signal allows the data output module to confirm that the second data processing module has written all the task data corresponding to the current task into the second data buffer module. At this point, the data output module reads the task data corresponding to the current task from the second data buffer module. Since the execution of the current task is interrupted by an interrupt signal, the data output module does not receive the complete output data corresponding to the current task. In this case, the NPU can send a data supplementation command to the data output module via signal line 1. Upon receiving this command, the data output module can complete the output data corresponding to the current task by padding with zeros and then output it.

[0046] Optionally, the first communication module may include a second data processing module, a central control module, a data output module, and a signal line for connecting the second data processing module, the central control module, and the data output module. For example,... Figure 4 As shown, the second data processing module can send a write completion signal to the data output module via signal line 2 through the central control module. Similarly, since the execution of the current task is interrupted by an interrupt signal, the data output module does not receive the complete output data corresponding to the current task. At this time, the NPU can send a data supplementation command to the data output module via signal line 2 through the central control module. After receiving the command, the data output module can supplement the output data corresponding to the current task by padding with zeros and other methods before outputting it.

[0047] Optionally, when the write completion signal can be sent from the second data processing module to the data output module via signal line 1, the data supplementation command can also be sent from the second data processing module via signal line 2 to the data output module via the central control module.

[0048] Alternatively, a second signal can be sent to the second mailbox module to clean up the task data corresponding to the current task in the second data buffer module. This second signal can be used to trigger the data output module to read and output the task data corresponding to the current task from the second data buffer module. The second signal can include a fake write signal and a write completion signal. The fake write signal can be used to start a fake write thread, and the write completion signal can be used to indicate that the second data processing module has finished reading the task data corresponding to the current task from the first data buffer module.

[0049] More specifically, such as Figure 4 As shown, when it is necessary to clean up the task data corresponding to the current task in the second data buffer module, the second data processing module can first send a fake write signal to the second mailbox module to indicate that the "fake write" thread has been started. Then, through the "fake write" thread, it sends a write completion signal (such as the psync signal) to the second mailbox module. This indicates that the second data processing module has written all the task data corresponding to the current task into the second data buffer module, but in reality, the second data processing module has not performed the operation of writing the task data corresponding to the current task. When MAILBOX receives the fake write signal and the write completion signal (such as the psync signal) in succession, it can reduce the available storage space of the current second data buffer module. The reduced available storage space is exactly the same as the storage space required for the task data corresponding to the current task in the second data processing module. This allows the data output module to determine that the second data processing module has written all the task data corresponding to the current task into the second data buffer module. At this time, the data output module can read the task data corresponding to the current task from the second data buffer module and output it, thereby realizing the cleanup of the task data corresponding to the current task in the second data buffer module.

[0050] S130: If the content of the interrupt signal indicates that the current task is paused and the next task is started, the task status data corresponding to the current task is stored. The task status data is used by the second data processing module to resume the execution of the current task after the next task is completed.

[0051] The task status data corresponding to the current task represents the processing progress of the second data processing module. More specifically, the task status data can be data information from the registers of the second data processing module. Alternatively, the second data processing module can input the task status data corresponding to the current task into its internal memory for storage.

[0052] S140: Execute the next task corresponding to the interrupt signal.

[0053] In one approach, when the second data processing module completes step S120 or S130, the second data processing module can send a task request to the central control module. This task request allows the central control module to determine that the second data processing module can begin executing the next task corresponding to the interrupt signal. After responding to the task request, the central control module can send the next task information corresponding to the interrupt signal (e.g., the data storage location of the next task) to the second data processing module so that the second data processing module can execute the next task corresponding to the interrupt signal.

[0054] This embodiment provides a task data processing method. When the second data processing module responds to a received interrupt signal and acquires the content of the received interrupt signal, if the interrupt signal indicates termination of the current task and commencement of the next task, the method clears the task data corresponding to the current task in both the first data buffer module and the second data processing module, and also clears the task data corresponding to the current task in the second data buffer module. If the interrupt signal indicates pause of the current task and commencement of the next task, the method stores the task status data corresponding to the current task. This task status data is used by the second data processing module to resume execution of the current task and the next task corresponding to the interrupt signal after the second data processing module has completed the next task. This method allows for the clearing or storage of task status data corresponding to the current task based on the interrupt signal, avoiding data processing anomalies when the electronic device executes the next task corresponding to the interrupt signal.

[0055] Please see Figure 5 This application provides a task data processing method applied to an electronic device, comprising a first data processing module, a second data processing module, a first data buffer module, and a second data buffer module. The first data buffer module stores data output by the first data processing module. The second data processing module reads data from the first data buffer module during task execution, processes it, and outputs the processed data to the second data buffer module. The electronic device further includes a first mailbox module for communication between the first data processing module and the second data processing module. The method includes:

[0056] S210: The second data processing module responds to the received interrupt signal and obtains the content of the received interrupt signal.

[0057] S220: If the content of the interrupt signal indicates that the current task is terminated and the next task is started, clear the task data corresponding to the current task in the first data buffer module and the second data processing module, and clear the task data corresponding to the current task in the second data buffer module.

[0058] S230: If the content of the interrupt signal indicates that the current task is paused and the next task is started, the task status data corresponding to the current task is stored. The task status data is used by the second data processing module to resume the execution of the current task after the next task is completed.

[0059] S240: If the interrupt signal indicates that the current task is paused and the next task is started, a first status signal is sent to the first data processing module through the first mailbox module to prevent the first data processing module from sending data to the first data buffer module.

[0060] The first status signal can be a signal indicating that the storage space of the first data buffer module is full; for example, the first status signal can be the pstatus signal. As one approach, when the second data processing module stops reading data from the first data buffer module, the first data processing module will continue writing data to the first data buffer module. When the storage space of the first data buffer module is full of data written by the first data processing module, the first mailbox module can send the first status signal to the first data processing module to confirm that the storage space of the first data buffer module is full, and thus stop sending data to the first data buffer module.

[0061] As one approach, once the first data processing module stops sending data and the second data processing module has finished saving the status data corresponding to the current task, the second data processing module can read the data corresponding to the next task from the electronic device's memory and output the processing result to the storage location corresponding to the output data of the next task. For example... Figure 6 As shown, the second data processing module can read the data corresponding to the next task from area A of memory 1 and output the processing result to the storage location corresponding to the output data of the next task, namely area B of memory 1 and area C of memory 2.

[0062] S250: In response to the completion of the next task, read the stored task status data.

[0063] In one approach, the second data processing module can send a recovery request to the central control module after completing the next task corresponding to the interrupt signal. This recovery request can enable the central control module to determine that the second data processing module can continue to execute the task before the interrupt signal. After responding to the recovery request, the central control module can send a recovery confirmation to the second data processing module. After receiving the recovery confirmation, the second data processing module can read the stored task status data from its internal memory.

[0064] Alternatively, the second data processing module can directly read the stored task status data from the internal memory after completing the next task corresponding to the interrupt signal.

[0065] S260: Based on the task status data, a second status signal is sent to the first data processing module through the first mailbox module to control the first data processing module to resume the execution of the current task and output data to the first data buffer module.

[0066] The second status signal can be a signal indicating that the first data buffer module still has available storage space. For example, the second status signal can be the pstatus signal. As one approach, when the second data processing module resumes execution of the task interrupted by the interrupt signal, it reads the data corresponding to the task from the first data buffer module and sends a read signal (e.g., a csync signal) to the first mailbox module. When the first mailbox module receives this read signal, it can increase the available storage space of the first data buffer module. This available storage space is the same as the data storage space read by the second data processing module. Furthermore, the first mailbox module can send the second status signal to the first data processing module to confirm that the first data buffer module still has available storage space, thereby allowing the first data processing module to continue sending the data corresponding to the task before the interrupt signal to the first data buffer module.

[0067] This embodiment provides a task data processing method that, through the aforementioned approach, allows for the clearing or storage of current task data based on interrupt signals, preventing data processing anomalies when the electronic device executes the next task corresponding to the interrupt signal. Furthermore, in this embodiment, when the interrupt signal indicates a pause in the current task and the commencement of the next task, the second data processing module can, after completing the next task corresponding to the interrupt signal, continue executing the task interrupted by the interrupt signal by reading the task status data corresponding to the task prior to the interrupt signal, thereby improving the flexibility of the task execution process.

[0068] Please see Figure 7This application provides a task data processing device 400, which operates in an electronic device. The electronic device includes a first data processing module, a second data processing module, a first data buffer module, and a second data buffer module. The first data buffer module stores data output by the first data processing module. The second data processing module reads data from the first data buffer module during task execution, processes it, and outputs the processed data to the second data buffer module. The electronic device also includes a first mailbox module for communication between the first data processing module and the second data processing module. The device 400 includes:

[0069] The signal response unit 410 is used by the second data processing module to obtain the content of the received interrupt signal in response to the received interrupt signal.

[0070] The task data cleaning unit 420 is used to clean up the task data corresponding to the current task in the first data buffer module and the second data processing module, and to clean up the task data corresponding to the current task in the second data buffer module, if the content of the interrupt signal indicates that the current task is terminated and the next task is started.

[0071] The task status data storage unit 430 is used to store the task status data corresponding to the current task if the interrupt signal pauses the current task and starts executing the next task. The task status data is used by the second data processing module to resume the execution of the current task after the second data processing module has completed the next task.

[0072] The task execution unit 440 is used to execute the next task corresponding to the interrupt signal.

[0073] In one approach, the task data cleaning unit 420 is specifically used to clean up the task data corresponding to the current task in the second data processing module through a reset signal; and to send a first signal to the first mailbox module, the first signal being used to notify the first data processing module through the first mailbox module that the task data corresponding to the current task in the first data buffer module is in a cleanable state.

[0074] Optionally, the electronic device further includes a data output module and a first communication module. The data output module is used to read data from the second data buffer module and output it. The task data cleaning unit 420 is specifically used to send a write completion signal to the data output module through the first communication module. The write completion signal is used to trigger the data output module to read the task data corresponding to the current task in the second data buffer module, and to supplement the read task data before outputting it.

[0075] Optionally, the electronic device further includes a data output module and a second mailbox module. The second mailbox module is used for communication between the second data processing module and the data output module. The data output module is used to read data from the second data buffer module and output it. The task data cleaning unit 420 is specifically used to send a second signal to the second mailbox module. The second signal is used to trigger the data output module to read the task data corresponding to the current task in the second data buffer module and output it.

[0076] Alternatively, the task status data storage unit 430 is specifically used to send a first status signal to the first data processing module through the first mailbox module if the content of the interrupt signal indicates that the current task is paused and the next task is started, so as to prevent the first data processing module from sending data to the first data buffer module.

[0077] In another manner, the task execution unit 440 is specifically used to read the stored task status data in response to the completion of the next task; and to send a second status signal to the first data processing module through the first mailbox module based on the task status data, so as to control the first data processing module to resume the execution of the current task and output data to the first data buffer module.

[0078] The following will combine Figure 8 This application describes an electronic device.

[0079] Please see Figure 8 Based on the aforementioned task data processing method and apparatus, this application embodiment also provides another electronic device 100 capable of executing the aforementioned task data processing method.

[0085] In summary, the task data processing method, apparatus, and electronic device provided in this application, after the second data processing module responds to a received interrupt signal and obtains the content of the received interrupt signal, if the content of the interrupt signal indicates termination of the current task and commencement of the next task, clears the task data corresponding to the current task in both the first data buffer module and the second data processing module, and also clears the task data corresponding to the current task in the second data buffer module. If the content of the interrupt signal indicates pause of the current task and commencement of the next task, the task status data corresponding to the current task is stored. This task status data is used by the second data processing module to resume execution of the current task and execute the next task corresponding to the interrupt signal after completing the next task. This approach allows for the clearing or storage of task status data corresponding to the current task based on the interrupt signal, avoiding data processing anomalies when the electronic device executes the next task corresponding to the interrupt signal.
