Timer calling method, device and equipment and computer readable storage medium

Abstract

The invention discloses a timer calling method, device and equipment, and a computer readable storage medium. The timer calling method comprises the following steps: collecting timing duration corresponding to a timer applied by each task in an embedded real-time operating system; grouping the timing durations in multiple relation in the timing durations into the same time sequence to obtain the time sequence corresponding to the timing durations; and applying for a target timer corresponding to the time sequence according to the time sequence, and calling the target timer when the timing duration in the time sequence is called. According to the method and the device, the situation that each task in the embedded real-time operating system needs to apply for a plurality of timers and the situation that the tasks need to apply for a plurality of timers when the tasks are executed can be avoided, so that the embedded real-time operating system calls fewer timers when the tasks are executed, and then the wakeup frequency of the system is reduced; therefore, the power consumption is reduced and the system performance is improved.

Description

technical field [0001] The invention relates to the technical field of embedded real-time operating systems, in particular to a timer calling method, device, equipment and computer-readable storage medium. Background technique [0002] In the embedded real-time operating system, when performing tasks, timers are often used to perform specified tasks. In fact, different tasks will apply for multiple timers with different durations, and each time the timer is called to calculate the time, the device needs to be woken up for timing. Therefore, when executing a task, due to the large number of timers that need to be called, the device needs to be woken up for timing when the timer is called multiple times, which not only occupies system resources, but also leads to increased power consumption of the device and increased consumption of system resources. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does no...
