Soft real-time timing device module and method for soft real-time timing device scheduling

Abstract

The invention relates to a method for dispatching a soft real-time timer and a module thereof, which comprises a dispatching unit, an interrupting unit, an initializing unit and a management unit. The dispatching unit is used for controlling a timer dispatching thread of a set up soft real-time timer, and the inside of the dispatching unit is an unlimited circulation body always obtaining counting semaphores; the interrupting unit is used for controlling the interrupting of the timer and releasing the counting semaphores; wherein, the dispatching unit is synchronous with the interrupting unit through a counting semaphore; the initializing unit is used for initializing overall variation of the timer so as to connect the interrupting unit and interrupting signals of a hardware clock and to initialize the dispatching unit; the overall variation comprises the counting semaphores; the management unit is a front desk window for users to control the timer, and users set up various soft real-time timers through the management unit and then set various operation instruments for the timer. By applying the invention, through an information mechanism, when the timer sends out appointed information to a senior user at time, the portability of a cell phone platform and various demands of the senior user on the cell phone platform can be met.

Description

technical field [0001] The invention relates to the field of mobile phones, in particular to a method for scheduling a soft real-time timer in a mobile phone platform architecture and a soft real-time timer module. Background technique [0002] Various operating systems used in the field of mobile phones provide a set of timer function interfaces, which use hardware clock interrupts to execute user entity functions in interrupt contexts or thread contexts to implement timer execution and scheduling; however, the timers provided by each operating system The function interfaces are not the same, and cannot directly meet the requirements of the mobile phone platform and portability, let alone meet the many needs of the upper-level users of the mobile platform, such as a large amount of timer usage, less system resource occupation, rich function interface input parameters, and convenient programming. And the timer can be paused and continued to operate. Therefore, there is curr...
