[理工] 106中央計組 第3題已刪文
想請問各位大大~
3.Consider the following code sequence:
SUB R2, R1, R3
AND R4, R2, R5
OR R7, R6, R2
ADD R8, R2, R2
SW R9, 100(R2)
Which of the following statements about
the dependency in the code sequence are correct?
(c) The two dependencies between SUB and ADD instructions are not hazards.
請問C選項
SUB跟AND的 $R2 不是(RAW) hazard嗎?
為什麼答案卻說C是對的呢??
