Timer coalescing : ウィキペディア英語版 | Timer coalescing Timer coalescing is a computer system energy-saving technique that reduces central processing unit (CPU) power consumption by reducing the precision of software timers to allow the synchronization of process wake-ups, minimizing the number of times the CPU is forced to perform the relatively power-costly operation of entering and exiting idle states.〔 *The Linux kernel gained support for deferrable timers in 2.6.22,〔〔 and controllable "timer slack" for threads in 2.6.28 allowing timer coalescing.〔〔 *Timer coalescing has been a feature of Microsoft Windows from Windows 7 onward. *Apple's XNU kernel based OS X gained support as of OS X Mavericks.〔〔 == See also ==
