A circuit such as a host adapter includes a timer capable of detecting time-outs for multiple pending commands. The timer includes a single free- running counter, a first storage for start counts, a second storage for time-out values, a subtractor, and a comparator. The start counts are co...
They can also generate alarms when they reach a specific value, defined by the software. The value of the counter can be read by the software program.Now with these new 16 ISR-based timers (while consuming only 1 hardware timer), the maximum interval is practically unlimited (limited only ...

private static void TimerEventProcessor(Object myObject, EventArgs myEventArgs) { myTimer.Stop(); // Displays a message box asking whether to continue running the timer. if(MessageBox.Show("Continue running?", "Count is: " + alarmCounter, MessageBoxButtons.YesNo) == DialogResult.Yes) { //...
, DateTime.Now.ToString("h:mm:ss.fff"), (++invokeCount).ToString()); if(invokeCount == maxCount) { // Reset the counter and signal Main. invokeCount = 0; autoEvent.Set(); } } } Remarks The callback method is invoked once after dueTime elapses, and thereafter each time the ...

Time Stamp Counter 使用汇编指定获取时间戳的计数器,精度应该是最高的,效率可能也应该是最高的,一条汇编指令rdtscp(相比rdtsc,rdtscp可以避免,因为cpu乱序执行带来的误差问题)即可。是可以作为一个选择的,腾讯的libco就是优先使用这个方法获取时间的。 clock_gettime() 。默认是nanosecond 级精度,是系统调用(_sys_cl...
