在這個實作中,system_clock與high_resolution_clock是同義詞。 Members 公用Typedefs 名稱 描述 system_clock::duration duration<rep, period>之同義資料表。 system_clock::period 用來表示duration中具現化的刻度期間的型別之同義資料表。 system_clock::rep ...
如果您想做基准测试，您最好的选择可能是std::high_resolution_clock，因为您的平台很可能对此时钟使用高...

Define system clock. system clock synonyms, system clock pronunciation, system clock translation, English dictionary definition of system clock. Noun 1. system clock - a time-of-day clock in a computer system clock - a timepiece that shows the time of da
Calibrating the system clock with a delta-sigma loop, for example, reduces the clock error over time. This allows accurate adjustment of the system clock to compensate for errors due to trim resolution, circuit noise and temperature.Matthew Bond...
If your app requires greater resolution than that offered by the Timer class or the system clock, use the high-resolution multimedia timers; see How to: Use the High-Resolution Timer. If the interval is set after the Timer has started, the count is reset. For example, if you set the in...
Because theTimerclass has the same resolution as the system clock, which is approximately 15 milliseconds on Windows 7 and Windows 8 systems, thecallbackdelegate executes at intervals defined by the resolution of the system clock ifperiodis less than the resolution of the system clock. Ifperiodis...
The system clock is continuously powered, and the reference clock is powered only during the calibration routine. 这些技术包括基于在固定数量时钟循环内系统时钟和基准时钟的频率之间的差来确定系统时钟的时钟误差,并调整系统时钟的微调值以补偿时钟误差. These techniques include between frequency based on a ...
