In this application, it provides a kind of method and device of multitasking, calculate equipment and computer-readable storage
Medium is described in detail one by one in the following embodiments.
The method of the present embodiment is used in the system including multiple processors, is formed for the associated multiple tasks of having time
Goal task, so that each processor is undertaken being adapted to it for task, and successively execute by operation timing, to realize at multitask
Manage the optimization of efficiency.
To achieve the goals above, the embodiment of the present application discloses a kind of method of multitasking, referring to Fig. 1, including
Following step 101~104:
101, goal task is split as multiple tasks according to timing.
By taking goal task is the modeling of threedimensional model as an example, including establishing the triangle gridding of threedimensional model, generating three-dimensional table
Surface model, texture mapping, model rendering generate 4 steps of two dimensional image.Each step can also be split as multiple sub-steps, example
The triangle gridding for such as establishing threedimensional model includes indicating grid and index two sub-steps of triangle gridding, and texture mapping includes definition
Texture object generates texture object array, defines texture object, load four sub-steps of texture.
As it can be seen that the step of having only includes a step, there is no the sub-step of subdivision, the step of having may include multiple sons
Step.It so, can be and corresponding as the task using sub-step using each step as a task when actually splitting
Subtask.Such as goal task is split as 1~task of task 4 according to timing, wherein task 2 includes that subtask 21 and son are appointed
Business 22, task 3 include subtask 31, subtask 32, subtask 33 and subtask 34.
102, the corresponding task execution function of each task is determined, and according to the corresponding task execution function of each processor

Function determines according to the corresponding task execution function of each processor and executes the corresponding processor in each subtask.
It is further to note that the corresponding task execution function of each processor can be different from each other, there may also be
Multiple processors correspond to the situation of same task execution function.
In the case where at least two processors correspond to same task execution function, according to the corresponding task of each processor
It executes function and determines the corresponding processor in each subtask of execution, comprising: select any processor as the execution subtask pair
The processor answered.
For example, in the system for including multiple processors at one, including processor Core1, processor Core2, processor
Core3 and processor Core4.Wherein, the corresponding task execution function of processor Core1 is 100, processor Core2 is corresponded to
Task execution function be 150, the corresponding task execution function of processor Core3 is 200, processor Core4 is corresponding
Task execution function is 50.Wherein, processor Core2, processor Core3 and the corresponding task execution of processor Core4
Function has 5.So, determine the corresponding task execution function of subtasking be 5 task execution functions wherein it
In the case where one, any processor in selection processor Core2, processor Core3 and processor Core4 is as the execution son
The corresponding processor of task.
In addition, it is necessary to explanation, do not include the situation of subtask for task, in step 102 according to each processing
The corresponding task execution function of device, which determines, executes the corresponding processor in each subtask, comprising: at least two adjacent tasks
In the case that corresponding task execution function corresponds to same processor, which is executed into at least two adjacent tasks
Corresponding processor.
It include the situation of subtask for task, for former and later two adjacent subtasks, the basis in step 102 is each
The corresponding task execution function of processor, which determines, executes the corresponding processor in each subtask, comprising: adjacent at least two
In the case that the corresponding task execution function in subtask corresponds to same processor, which is executed described adjacent at least two
The corresponding processor in a subtask.
Such as current subtask, corresponding processor is Core1, task execution corresponding for next subtask
Function can be the task execution function in processor Core1, or the task execution function in processor Core4, that
Preferably using processor Core1 as the corresponding processor in next subtask.In this way, processor Core1 can execute it is adjacent
Two subtasks avoid that two adjacent subtasks are gone that different processors is called to go to handle again, thus ensure that son
Under the premise of the operation order of task, optimize the treatment effeciency of multitask.
103, the calling sequence of multiple processors is determined according to the timing of multiple tasks.
Include the situation of subtask for task, determines that the calling of multiple processors is suitable according to the timing of multiple tasks
Sequence, comprising: the calling sequence of multiple processors is determined according to the timing of multiple subtasks.
Table 2 shows the calling that the multiple tasks of goal task or the timing of subtask are determined with 4 processors
The result of sequence.
Table 2
It should be noted that corresponding task execution function both can be Core1 pairs with processor for subtask 22
It answers, it can also be corresponding with processor Core2.In the case where the corresponding processor in subtask 21 is Core2, then it is preferred that son is appointed
Corresponding processor be engaged in as Core2.
104, the processor is successively called according to the calling of the multiple processor sequence, executes the goal task.
The method of multitasking provided by the present application, by the way that goal task is split as multiple tasks according to timing；Really
Determine the corresponding task execution function of each task, and is determined according to the corresponding task execution function of each processor and execute each appoint
It is engaged in corresponding processor；The calling sequence of multiple processors is determined according to the timing of multiple tasks, it can be ensured that the case where running
Under, each processor obtains correct calling sequence, it can ensure that each processor undertakes the task adaptable with it in this way, and
