Note: Clock Gating

根據CICeNEWS(86期, 2007)的說明, Clock Gating是利用一個And閘, 來關閉模組的Clock訊號。這樣的作用是, 關閉後的模組可以避免運作時產生的動態功率消耗 (可能占總功率消耗的80%)

>> 這似乎也能用來切換模組的Clock

Question Mark

One question mark, the first means one question in the mind.
Two question marks, the second may mean why don't your answer me.
Three question marks, the third one may mean how dare you don't replay me until this time.
...
When seeing a line of question marks, I wonder what do you really want?
Does it mean an emergent question?
Or you get used to use it because lack of notice?
Or you just expect a immediate reply?

Yes, I have some questions.
