Embodiment Construction
[0037] Such as figure 1 As shown, the task two-level scheduling module of the present invention provides a task operation interface for the application layer user, hangs the task on the corresponding thread of the real-time operating system according to the priority, and distributes and processes the thread message, such as figure 2 As shown in the figure, tasks A and B are hung on thread A, and task C is hung on thread B, so that the user's three task applications can be completed on two threads, saving thread resources.
[0038] Specifically, the task secondary scheduling module includes an initialization submodule, a task scheduling processing submodule and a task operation submodule. in,
[0039] The initialization sub-module is used to initialize the task secondary scheduling module, and create a thread registration table for saving task information under the thread;
[0040] The task scheduling processing sub-module is used to receive the message sent to this thread, ...
