Timer implementation method

Abstract

The related implementation method for a timer comprises: pre-defining new timer, initiating timer task, recording all events and timing cycle and recall function information in register; using the new-defined timer to obtain signal from original timer and trigger the new one; querying overt-time event from its register, yes to call the corresponding recall function. This invention reduces timer load and improves precision.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for realizing a timer. Background technique [0002] Timer is a common and necessary technology in software development. Timer is a collection of a series of functions. By using the methods provided by it, the software can complete the specified function within a fixed time. Its purpose is to make software automatically perform certain operations or tasks within a fixed period of time. Usually, high-precision timers are implemented by means of interrupts provided by hardware timers, which are also the most accurate benchmark timers in software systems. [0003] In general, in order to complete the function of "automatically performing certain operations within a fixed time" (for example: the function of sending and receiving data packets by the timer), the original timer of the software system is directly used. However, if there are many tasks and the original timer of the sys...

Problems solved by technology

However, if there are many tasks and the original timer of the system is used too frequently, the timing accuracy of the original timer will be greatly reduced, thus affecting the normal use of the timing function.
