500微秒的实时循环周期 [英] 500 microsecond real-time cycle period

问题描述

大家好，

我一直在阅读实时计时器和RTOS功能。如果我们需要一个500微秒的软实时循环时间，我们首先需要一个定时器，它为我们提供每500微秒的分辨率。

我尝试了多媒体计时器并获得1毫秒分辨率。但它不能满足需要。

现在似乎只能用硬件计时器来完成这项任务。 

我使用PC-104和嵌入式标准Windows 7。

现在问题是，是否可以使用软件完成此任务CPU占用率低的计时器？

解决方案

Windows仍然可能无法为您提供支持需要。有适用于Windows的实时附加解决方案。有TenAsys的银泰：  http：// www。 tenasys.com/index.php/tenasys-products/intime-rtos-family/intime-for-windows

Hi all,

I have been reading real time timers  and RTOS capabilities. If we need a soft real time cycle time of 500 microseconds we first need a timer that provides us a tick on every 500 microseconds with a resolution. 

I tried multimedia timer and obtained 1 milisecond resolution. But it doesn't satisfy the need.

Now it seems that it is only possible to achieve this task with a hardware timer. 

I use a PC-104 and an embedded standard windows 7.

Now the question is, is it possible to do this task with a software timer with a low CPU usage?

解决方案

Windows still might not provide the support you need. There are real-time add on solutions available for Windows. There is TenAsys' INtime: http://www.tenasys.com/index.php/tenasys-products/intime-rtos-family/intime-for-windows ?
