About: Timer coalescing

An Entity of Type: topical concept, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

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.

Property Value
dbo:abstract
  • 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. (en)
  • 定时器汇聚是计算机系统的节能技术，通过降低软件定时器的精度以允许进程唤醒同步来节约CPU被迫执行的昂贵的进入与退出的次数，从而降低CPU能耗。 * Linux内核通过从版本2.6.22开始支持可延迟定时器（deferrable timer），从版本2.6.28支持可控的定时器松弛（timer slack）。 * Windows 7开始支持定时器汇聚。 * Apple的基于XNU内核的OS X，称作OS X Mavericks，支持此功能。 (zh)
