新内核的hrtimer的触发和设置不像之前在定期的tick中断中进行,而是动态调整的,即基于事件触发,hrtimer的工作原理:通过将高精度时钟硬件的下次中断触发时间设置为红黑树中最早到期的 Timer 的时间,时钟到期后从红黑树中得到下一个 Timer 的到期时间,并设置硬件,如此循环反复。 在高精度时钟模式下,操作系统内核仍然需要周...

1.With the Digilert 100 operating,set the Mode switch to Total.The display shows SET,the hourglass,and the most recent timing period used.The first time you use the timer,the setting is 00:01,which means one minute.2.Use the + and - buttons to set the timing period.The timed period ...
--简单地说就是过一段时间调用一次该函数 setInterval() 方法会不停地调用函数，直到 clearInterval() 被调用或窗口被关闭。由 setInterval() 返回的 ID 值可用作 clearInterval() 方法的参数。代码演示如下 var backId=setInterval("aaa()",1000); $('.aaa').mouseover(function(){ clearInter ...
