无限循环会消耗100％的CPU [英] Infinite looping consumes 100% CPU

问题描述

我陷入了需要产生一定Hz定义频率的情况.我已经尝试了多媒体计时器和Internet上所有其他可用的东西，但是到目前为止，如果有其他条件的无限循环给了我最好的结果.但是这种方法的问题在于，它消耗了几乎所有的cpu，没有空间让其他应用程序正常工作.

I am stuck in a situation where I need to generate a defined frequency of some Hz. I have tried multimedia timers and all other stuff available on the internet but so far an infinite loop with some if-else conditions gave me the best results. But the problem in this approach is that it consumes almost all of the cpu leaving no space for other applications to work properly.

我需要一种算法，该算法可以生成从Hz到KHz的频率.

I need an algorithm with either generates frequency of some Hz to KHz.

我正在Windows平台上使用C#.

I am using windows plateform with C#.

推荐答案

您无法在非实时平台上准确生成固定频率的信号.任何时候，来自同一进程或其他进程的高优先级线程都可能阻止线程的执行.例如.当GC线程启动时，辅助线程将被挂起.

You can't accurately generate a signal of a fixed frequency on a non-realtime platform. At any moment, a high priority thread from same or other process could block the execution of your thread. E.g. when GC thread kicks in, worker threads will be suspended.

话虽这么说，您被允许的抖动是多少?需要支持的最高频率是什么?

That being said, what is the jitter you are allowed to have and what is the highest frequency you need to support?
