    说明:

    执行6级流水作业:

    1. fetch(取指)

    2. decode(译码)

    3. dispatch/renaming(分发/重命名)

    4. select/wakeup(选择/唤醒)

    5. execution/mem access/finish(执行/存取/结束)

    6. complete/retire(完成/恢复)

    六级流水作业的另一种划分说法:

    The six-stage pipeline should be divided into the following stages:

    Instruction Fetch (取指)-- request instruction from iMem and update PCDecode(译码) -- receive response from iMem and decode instructionRegister Fetch(取寄存器) -- read from the register fileExecute(执行) -- execute the instruction and redirect the processor if necessaryMemory(存储) -- send memory request to dMemWrite Back(回写) -- receive memory response from dMem (if applicable) and write to register file

    设计完成后的芯片:
