Draw and explain 6 stage CPU instruction pipeline

Free Discussion

If the instruction processing is split into 6 phases then the pipelined CPU will have 6 different stages for the execution of the sub phases.

The six stages are as follows :
  1. Fetch Instruction : Instruction are fetched from the memory into a temporary buffer before it gets executed.

  2. Decode Instruction :The intstruction is decoded by the CPU so that the necessary OP codes and operands can be determined .

  3. Calculate Operand :It is based on the addressing scheme used, either operands are directly provided in the instruction or the effective address has to be calculated.
  4. Fetch Operand :Once the address is calculated,the operands need to be fetched from the address that was calculated. This is done in this phase.

  5. Execute Instruction :The instruction can now be executed .

  6. Write Operand :Once the instruction is executed, the result from the execution needs to be stored or written back in the memory.
