问题示例: A five-stage in-order pipeline uses operand forwarding. Instruction I1 writes R5 in its EX stage, and immediately following instruction I2 requires R5 as an ALU input in its EX stage. Assuming no cache or control hazards, what is the usual result? I2 can proceed without a stall, I2 must wait until I1 reaches write-back, The processor must flush the entire pipeline, I1 is restarted after I2 completes
