Supporting High-Resolution Timers (Windows Embedded CE 6.0) 發行項 2012/01/05 本文內容 To support high-resolution timers See Also 1/5/2010 The high-resolution timer functions QueryPerformanceCounter and QueryPerformanceFrequency allow independent software vendors (ISVs) to use the high-resolution ...
The Timer API Windows NT bases all of its timer support off of one system clock interrupt, which by default runs at a 10 millisecond granularity. This is therefore the resolution of standard Windows timers. When a multimedia application uses thetimeBeginPeriodmutlimedia API, which is exported by...
In many cases, 64-bit high-resolution counters are not implemented in hardware platforms. A workaround is to implement the counter using 32-bit hardware counters and implement the rollover to 64-bits through an interrupt. Another is to use the thread scheduling timer to update a 64-bit tick...
Some devices support a high-resolution timer. This timer, when present, provides more precise measurements than you can obtain by using the TickCount property, which has a 1-millisecond resolution. In applications where precise time measurements are important, the high-resolution timer provides the ...
vR0001, Thank you for posting in the Intel® Communities Support. We will do further research to confirm if the Intel® Xeon® E-2176M processor supports high-resolution timer default, as soon as I get any updates I will post all the details on this thread. Regards, Alberto R. ...
关于High-Resolution Timer(了解) 如果一个系统包含高精度性能计数器(HRPC,high-resolution performance counter)则此系统提供高精度定时器。你可以使用API函数QueryPerformanceFrequency来获得HRPC的频率HRPCF,返回值为cps(counts per second)。这个依赖于处理器(processor dependent),在一些处理器中HRPCF的值可能就是处理器...
关于Linux的 High-Resolution Timer 若是禁用High-Resolution Timer,那么内核是在毫秒级别处理内部时间分片。 禁用掉High-Resolution Timer不会有问题,除非你的应用程序需要在纳秒级别处理时间分片。 如下摘自:Oracle Linux: How to Disable High-Resolution Timer (文档 ID 2207818.1)...
You can configure agent computers to use a high-resolution timer when collecting performance data. The high-resolution timer ensures that all measurements are precise to within 1 millisecond. Before you begin The high-resolution timer is used by default on the Linux operating system. You do not ...

Is there a high-precision timer API in MacOS like that Windows Multimedia Timers provide? I need execute my callback exactly every 1 ms, so I need an API allowing to fire events with this resolution. I can't find appropriate API for this. Ideally I want to use C++. As far as I kno...
