Example Embodiment
[0024] The embodiments and embodiments of the present invention will be described in detail below with reference to the drawings.
[0025] The scope of application of the present invention will be apparent from the detailed description given below. However, it should be understood that while the detailed description and specific examples illustrate preferred embodiments of the present invention, they are given for illustrative purposes only.
[0026] The tasks of the operating system are created, ready, running, waiting, suspended, and terminated. When the system is running, tasks will switch between each state, such as figure 1 Shown. After the system starts to schedule operation, the CPU (Central Processing Unit) is either performing a certain task or performing interrupt processing. During interrupt processing, the CPU uses the specific stack space allocated in interrupt mode, which is generally large enough to prevent stack overflow. Moreover, for the nesting and real-time na...
