AI总结:

本文提出一种自动重新配置计算资源的方法,实现无延迟的暂态管理,通过预测算法切换并提前执行计算,减少切换延迟。

摘要:

为了解决在突然改变动态算法(如数字滤波器或控制器)时引起的暂态问题,已开发出许多缓解方法。这些“无缝切换”方法具有计算负担且实施时间较长,导致延迟了期望的切换时间。本文开发了一种方法,以自动重新配置计算资源,实现一种无延迟切换时间的暂态管理方法。该方法在预测算法切换即将发生时会生成一个投机线,以便在切换发生前完成计算。描述了软件框架,并展示了在滤波器组中切换滤波器的实验结果。

英文摘要:

There are many methods developed to mitigate transients induced when abruptly changing dynamic algorithms such as those found in digital filters or controllers. These "bumpless transfer" methods have a computational burden to them and take time to implement, causing a delay in the desired switching time. This paper develops a method that automatically reconfigures the computational resources in order to implement a transient management method without any delay in switching times. The method spawns a speculative thread when it predicts if a switch in algorithms is imminent so that the calculations are done prior to the switch being made. The software framework is described and experimental results are shown for a switching between filters in a filter bank.
