什麼是non-critical circuits？

chip123

代問：只聽說過作業系統中臨界代碼，電流怎麼也有臨界電流？文件中整段話如下：

; q. H# x' O, ~) x+ v" G5 oThe system context is maintained in system DRAM, but power is shut off to non-critical circuits. Memory is retained, and refreshes continue. All clocks stop except RTC clock.
* C4 M8 a4 v+ i: j& a
麻煩各位大大幫幫忙。謝謝！

non-critical ==> 不重要的

8 P" T7 j4 ~) H8 E, X! @& ^% ^, X% g0 k這是在講sleep mode,比方說睡眠時硬碟和螢幕可以切掉電源來省電.
