write-back

基本解釋

In write-back mode the unit of memory access is the cache line, 64 bytes in the Core 2.
在回寫(xiě)式模式下，在64位機(jī)的酷睿2處理器中，存儲(chǔ)單元路徑就是緩存路線(xiàn)。
Typically kernels treat all RAM memory as write-back, which yields the best performance.
在這里輸入譯文典型的核心將所有的隨機(jī)存儲(chǔ)看作回寫(xiě)式，這樣抑制了存儲(chǔ)器最好的運(yùn)轉(zhuǎn)。
Any memory access that falls within a single cache line is guaranteed to be atomic (assuming write-back memory).
在這里輸入譯文任何屬于單獨(dú)緩存線(xiàn)的內(nèi)存存取肯定是回寫(xiě)式的。

So really, the rule of thumb if you think back to Scratch is -- that any time you write a statement -- -- something that does something in one line of code -- you generally need the semicolon there.
實(shí)際上，根據(jù)經(jīng)驗(yàn)，你們回憶一下在Scratch中,任何時(shí)候你們寫(xiě)一條語(yǔ)句-,處理一些操作的一行代碼-,你們通常需要在那里加個(gè)分號(hào)。
