Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0038] like figure 1 As shown, the soft real-time timer module of the present invention includes an initialization unit, an interrupt unit, a scheduling unit and a management unit,
[0039] Among them, if the timer provided by the mobile phone operating system is used directly, the system timer needs to be set as a periodic timer with the smallest unit, and the soft real-time timer interrupt control is executed inside the system timer.
[0040] An initialization unit, which is used to initialize the global variables of the soft real-time timer, initialize the interrupt unit and initialize the scheduling unit;
[0041] Among them, the global variables of the soft real-time timer include counting semaphores.
[0042] Initializing the interrupt unit refers to connecting the interrupt unit with the interrupt number of the hardware clock.
