說明:ide

執行6級流水做業:fetch

1. fetch(取指)spa

2. decode(譯碼).net

3. dispatch/renaming(分發/重命名)code

4. select/wakeup(選擇/喚醒)blog

5. execution/mem access/finish(執行/存取/結束)ip

6. complete/retire(完成/恢復)it

 

六級流水做業的另外一種劃分說法:pip

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

  • Instruction Fetch (取指)-- request instruction from iMem and update PC
  • Decode(譯碼) -- receive response from iMem and decode instruction
  • Register Fetch(取寄存器) -- read from the register file
  • Execute(執行) -- execute the instruction and redirect the processor if necessary
  • Memory(存儲) -- send memory request to dMem
  • Write Back(回寫) -- receive memory response from dMem (if applicable) and write to register file
