[0033] An embodiment of the present invention provides a method for optimizing multi-task processing of a single-chip microcomputer. First, an interrupt processing function is triggered periodically by a clock. Each time the interrupt processing function is triggered, a target task that meets a first preset condition is determined by polling a registered task list through the interrupt processing function. If the task time of the target task is less than a preset time, the interrupt processing function is exited after the target task is executed. If the task time of the target task is greater than or equal to the preset time, the target task is split into multiple subtasks and mounted into a subtask queue before exiting the interrupt processing function. On the other hand, the main loop function executes the subtasks in the subtask queue when the system is idle. The method for optimizing multi-tasking of a single-chip microcomputer provided in an embodiment of the present invention determines the task processing mode based on the task duration. When the task duration is short, it is directly executed through the interrupt processing function, and when the task duration is long, it is split and stored, and gradually processed through the main loop function when the system is idle. The task allocation and execution process is optimized, and it can ensure timely response to all interrupts and emergency events. At the same time, the idle resources of the system are effectively used to process tasks that take a long time, which significantly improves the overall performance and response speed of the system during multi-tasking, thereby avoiding the slow response problem caused by some tasks occupying CPU resources for a long time, and enhancing the stability and reliability of the system.

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0038] It should be mentioned before discussing the exemplary embodiments in more detail that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe the steps as sequential processes, many of the steps therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of the steps can be rearranged. The process can be terminated when its operation is completed, but can also have additional steps not included in the accompanying drawings. The process can correspond to a method, function, procedure, subroutine, subprogram, etc.

[0039] Embodiment 1

[0040] Figure 1 This is a flow chart of a method for optimizing multi-tasking of a single-chip microcomputer provided in the first embodiment of the present invention. This embodiment is applicable to the case of effectively scheduling time-consuming tasks on a single-chip microcomputer. The method can be executed by the device for optimizing multi-tasking of a single-chip microcomputer provided in the embodiment of the present invention. The device can be implemented by hardware and / or software, and can generally be integrated into a computer device, specifically a single-chip microcomputer. Figure 1 As shown, the specific steps include:

[0041] S11, triggering the interrupt processing function periodically through the clock.

[0042] S12: polling a registered task list through the interrupt processing function to determine a target task that meets a first preset condition.

[0043] S13: If the target task takes less time than a preset time, execute the target task and exit the interrupt processing function.

[0044] S14. If the task duration of the target task is greater than or equal to the preset duration, the target task is split into multiple subtasks, mounted into a subtask queue and the interrupt processing function is exited, so as to execute the subtasks in the subtask queue in the system idle state through the main loop function.

[0045] Specifically, the single-chip microcomputer program is provided with a main loop function and an interrupt processing function. The interrupt processing function can interrupt the interrupt or regular business process that is being executed with a lower priority than the interrupt processing function, such as the main loop function. When the interrupt processing function is processed, it can return to the position where the main loop function is interrupted to continue execution. In the single-chip microcomputer, the clock can be used to periodically trigger the interrupt processing function to interrupt the execution of the main loop function, thereby realizing the periodic scheduling of tasks. Optionally, the period of the clock is 1 millisecond.

[0046] After the interrupt handling function is triggered, the current registered task list can be polled to determine the target task that meets the first preset condition from the registered tasks, wherein the first preset condition can be set according to actual needs, and can specifically include waiting time conditions and / or priority conditions, etc. Optionally, the first preset condition is the highest priority and the longest waiting time. Before the system runs, the system environment can be initialized first, and a registered task list (List) can be established, each of which contains multiple tasks (Task). When the interrupt handling function is triggered, all registered task lists can be polled first to determine the target task list with the longest waiting time, and then the task with the highest priority (such as TaskA) can be selected from the target task list as the target task.

[0047] After determining the target task in the interrupt handling function, the time consumption of the target task can be evaluated first to determine whether the task consumption is less than the preset duration. If the task consumption is less than the preset duration, the target task can be run in the interrupt handling function, and the interrupt handling function can be exited after the task is completed. Among them, when running the target task, it will not be interrupted by the interrupt handling function triggered by other clocks. If the task consumption is greater than or equal to the preset duration, the target task can be decomposed into multiple subtasks (SubTask), and these subtasks can be mounted in the subtask queue (WorkSet). At the same time, the index of each subtask can be recorded, and the interrupt handling function will be exited after the subtask mounting is completed.

[0048] During the system idle operation, the main loop function can run uninterruptedly to execute the subtasks in the subtask queue. During the operation of the main loop function, if the interrupt processing function is triggered, the operation of the main loop function will be interrupted, and the operation of the main loop function will continue after exiting the interrupt processing function. That is, the main loop function needs to execute the subtasks in the subtask queue in the system idle state (that is, the state of not processing interrupts).

[0049] Optionally, executing the subtasks in the subtask queue in a system idle state through the main loop function includes: determining whether the subtask queue is empty; if not, determining a target subtask that meets a second preset condition from the subtask queue and executing it.

[0050] Specifically, the main loop function can select a subtask from the subtask queue to execute each time, and loop this operation. Then each loop can first determine whether the subtask queue is empty. If so, it means that there is no subtask that needs to be executed temporarily, and you can directly enter the next loop at this time. If not, you can determine from the subtask queue that the target subtask that currently meets the second preset condition is executed, and you can enter the next loop after completing the target subtask and releasing it. The second preset condition can be set according to actual needs, and can specifically include waiting time conditions and / or priority conditions, etc., so as to ensure that the execution order of tasks can be reasonably arranged when the system is idle. Optionally, the second preset condition is that the priority is the highest and the waiting time is the longest.

[0051] On the basis of the above technical solution, optionally, after polling the registered task list through the interrupt processing function to determine the target task that meets the first preset condition, it also includes: setting the state of the target task to a running state; after executing the target task, it also includes: setting the state of the target task to a paused state; after splitting the target task into multiple subtasks and mounting them into a subtask queue, it also includes: if all subtasks of the target task have been completed, setting the state of the target task to a paused state.

[0052] Specifically, each bit of a number of bytes can be used to record the status of the corresponding task or subtask, and a task status table can be generated so that the system can process according to the task status table. Among them, the status of a task or subtask can include a running state (Running) and a suspended state (Suspend). During the operation of the system, when the operation interrupt processing function selects a certain target task, the state of the target task in the task status table can be set to a running state. Then it can be checked whether the target task has related subtasks. If there are no related subtasks, that is, the task time of the target task is less than the preset duration, then the state can be set to a suspended state after completing the execution of the target task. If there are related subtasks, that is, the task time of the target task is greater than or equal to the preset duration, it can be determined in real time according to the task status table whether all related subtasks have been completed. If all related subtasks have been completed, the state of the target task can be set to a suspended state, otherwise it remains in a running state. In addition, when the interrupt handling function is running and a target task is selected again, it can first check whether there are any related subtasks that have not been completed, that is, there may be subtasks mounted by the same target task selected last time that have not been completed. If so, the execution of the current target task can be directly ended, the interrupt handling function can be exited, and the previous main loop operation can be continued to wait for the next interrupt scheduling. If not, and the task time of the current target task is greater than or equal to the preset duration, the related subtasks can be remounted.

[0053] Further optionally, the method also includes: if the status of all tasks in the registered task list are in a paused state, then the system enters a sleep state. Specifically, when the system enters an idle state and there are no other active tasks, the status of all tasks in the registered task list can be checked based on the task status table. If the status of all tasks is in a paused state, the system can enter a sleep state, otherwise it can continue to wait for the next inspection cycle. In the prior art, when it is necessary to enter a sleep mode, there is often a lack of resource protection and hardware resources are directly released, which may cause abnormal situations due to incomplete data preservation. The method for optimizing multi-tasking of a single-chip microcomputer provided in this embodiment decides whether to enter a sleep mode through state determination, and further improves the reliability of task scheduling of the single-chip microcomputer in a multi-tasking environment.

[0054] The technical solution provided by the embodiment of the present invention first triggers the interrupt processing function periodically through the clock, and each time the interrupt processing function is triggered, the target task that meets the first preset condition is determined by polling the registered task list through the interrupt processing function. If the task time of the target task is less than the preset time, the interrupt processing function is executed and then exited. If the task time of the target task is greater than or equal to the preset time, the target task is split into multiple subtasks and mounted in the subtask queue and then exits the interrupt processing function. On the other hand, the main loop function will execute the subtasks in the subtask queue in the idle state of the system. By determining the task processing method based on the task time, when the task time is short, it is directly executed through the interrupt processing function, and when the task time is long, it is split and stored, and the main loop function is gradually processed when the system is idle, the task allocation and execution process is optimized, and it can ensure timely response to all interruptions and emergency events. At the same time, the idle resources of the system are effectively used to process the tasks that take up a long time, which significantly improves the overall performance and response speed of the system during multi-task processing, thereby avoiding the slow response problem caused by some tasks occupying CPU resources for a long time, and enhancing the stability and reliability of the system.
