The task processing method and device of the embodiment of the present invention are mainly applied to a wearable device such as a smart watch, and may of course be applied to other terminal devices, which is not limited by the present invention. The following is a detailed description of the application to a smart watch.

Referring to FIG. 1, an embodiment of a task processing method of the present invention is proposed. The method includes the following steps:

S11. The main processing unit performs a high load task.

S12. When the high load task ends, the main processing unit notifies the processing unit to perform a low load task and automatically enters the low power mode.

In the embodiment of the present invention, the smart watch includes two processing units, which are a main processing unit and a slave processing unit, respectively. The processing unit is preferably an MCU (Microcontroller Unit), such as a master MCU and a slave MCU for the smart watch. The smart watch further includes a display unit 30, as shown in FIG. 2, preferably, the main processing unit 10, the processing unit 20 and the display unit 30 are sequentially connected, and the master-slave processing unit cascades to drive the display unit 30, so that The circuit is more streamlined, improving the stability and reliability of the circuit.

The performance of the main processing unit is strong, but the power consumption is large, which is mainly used to perform high-load tasks, so that the smart watch can smoothly run various complicated applications and realize various rich functions, thereby ensuring the performance of the smart watch. . The performance of the slave processing unit is weak, but the power consumption is low, and it is mainly used to perform low-load tasks. When the high load task ends, the main processing unit notifies the processing unit to perform a low load task and then automatically enters a low power mode (such as sleep mode). In low-power mode, the main processing unit greatly reduces the operating frequency and turns off most of the functions, leaving only the instruction reception function, which greatly reduces power consumption. This achieves a balance between performance and power consumption.

In the embodiment of the present invention, before the step S11, the main processing unit receives the task instruction. If the main processing unit is in the low power mode, the main processing unit switches from the low power mode to the working mode, and determines that the type of the task to be executed is high. Load tasks are also low load tasks. When the task to be executed is a high-load task, the process proceeds to step S11, that is, the main processing unit executes the high-load task; when the task to be executed is a low-load task, the main processing unit notifies the processing unit to perform the low-load task. .

The task command includes at least one of a button command, a communication command, a voice command, and the like. For example, when the button is triggered, the main processing unit receives the button command; when the wireless communication module (such as the Bluetooth module) sends information to the main processing unit, the main processing unit receives the task command; when the microphone receives the specific voice information The main processing unit receives the voice command.

When determining the type of task, if the task to be executed is a relatively complex task such as displaying a map, calculating real-time parameters, synchronizing data, displaying communication information, the main processing unit determines that the task to be executed is a high-load task; The task is a simple task or a standby task such as updating the time or updating non-real-time parameters, and the main processing unit determines that the task to be executed is a low-load task.

The display map, such as displaying GPS, displays map information of a current location, and calculating real-time parameters such as real-time statistics of steps, speed, distance, heart rate, blood pressure, and the like in a sports mode, such as a mobile phone, a tablet, etc. The device synchronizes the motion data, the address book data, and the like, and the display communication information is, for example, displaying the instant messaging information, the short message, the incoming call notification information, and the like sent by the terminal device. The update time is such as a timing (eg, about 1 minute interval) refresh time, and the update non-real-time parameters such as timing (eg, interval 2-5 minutes) refresh parameters such as temperature, air pressure, and timing in non-sport mode (eg, 1 minute interval) Left and right) Refresh the parameters such as the number of steps, speed, and distance.

Further, when the task to be executed is a low load task, the main processing unit automatically enters the low power mode. Therefore, even if the main processing unit is woken up from the low power mode by the task instruction, if the task corresponding to the task instruction is a low load task, the processing unit can restore the low power state in time, thereby greatly reducing power consumption.

In some embodiments, when the main processing unit is in the low power mode, the task instruction can also be received from the processing unit and the type of task to be executed is determined to be a high load task or a low load task. When the task to be executed is a high-load task, the main processing unit is woken up, so that the main processing unit enters the working mode from the low-power mode, and proceeds to step S11, that is, the main processing unit executes the high-load task; when the task to be executed is performed For low load tasks, the slave unit performs the low load task and the master processing unit maintains the low power mode.

Further, in order to further reduce power consumption, when the main processing unit performs a high load task, the main processing unit also notifies the processing unit to enter the low power consumption mode. Specifically, the main processing unit sends a low power mode instruction to the slave processing unit, and receives a low power mode command from the processing unit, and shorts the output to the input according to the instruction, such as shorting the output and the input by means of programming mapping. Thereby entering the low power mode.

At this time, in step S12, when the high-load task ends, the main processing unit sends a working mode command to the slave processing unit, receives the working mode command from the processing unit, and switches from the low power mode to the working mode according to the command, in the working mode. Perform low-load tasks such as update time, update non-real-time parameters, and so on.

In the specific implementation, the MT2523 can be used as the master MCU, and the FPGA (Field-Programmable Gate Array) is used as the slave MCU. The powerful main MCU achieves 30FPS speed on the 240*240 display, which can smoothly run various high-load operations such as GPS navigation; ultra-low-power MCU can independently complete simple clock refresh, even in the display When the screen is working 24 hours a day, the standby current is as low as 0.2 mA. This ensures the high performance and low power consumption of smart watches.

The task processing method of the embodiment of the present invention configures the master-slave two processing units to perform high-load tasks through the main processing unit to ensure the fluency of the system. When the high-load task ends, the main processing unit notifies the processing unit to execute. Low load tasks and automatically enter low power mode to reduce power consumption. Thereby, the high performance of the smart watch is ensured, the power consumption of the smart watch is reduced, the standby time is prolonged, and the balance between performance and power consumption is realized, and the high performance and low power consumption of the smart watch are taken into consideration.
