Zusammenfassung:The present invention discloses a device and method for dynamic clock adjustment. The device is applied to a real-time computing system and comprises: a decision timer for detecting a task time for a real-time computing system to perform a task and calculating a time difference between the task time and a real-time system period; a controller for receiving the time difference and generating a control signal based on the time difference and the reference time; and a clock generator for receiving a control signal to generate an adjusted system clock which then can be provided to the immediate computing system. The invention can realize the dynamic adjustment of the system clock in time to improve the computational efficiency of the real-time computing system. 本发明公开了种动态时钟调整的装置和方法,该装置应用于即时计算系统,包含:研判计时器,检测即时计算系统执行任务的任务时间,并且计算任务时间与即时系统周期的时间差;控制器,接收时间差,并且根据时间差与参考时间来产生控制信号;以及时钟产生器,接收控制信号来产生调整的系统时钟,以提供给即时计算系统。本发明可实现及时地动态调整系统时钟来改善即时计算系统的计算效率。
