Question

Add NOP instructions to the code below so that it will run correctly on a pipeline that does not handle data hazards. addi x11, x12, 5

add x13, x11, x12
addi x14, x11, 15
add x15, x13, x12

Answer 1

To eliminate data hazards and make the code run correctly, the student needs to add NOP instructions in the code. These instructions allow the pipeline to proceed smoothly without affecting data dependencies. we ensure that the pipeline stages proceed smoothly without any data hazards.

Step-by-step explanation:

To eliminate data hazards, we can insert NOP (No-Operation) instructions in the code. These instructions allow the pipeline to proceed without affecting the data dependencies. Here's how you can modify the code:

1. addi x11, x12, 5
2. NOP
3. add x13, x11, x12
4. NOP
5. addi x14, x11, 15
6. NOP
7. add x15, x13, x12

By inserting NOP instructions after each instruction, we ensure that the pipeline stages proceed smoothly without any data hazards. eliminate data hazards and make the code run correctly, the student needs to add NOP instructions in the code. These instructions allow the pipeline to proceed smoothly without affecting data dependencies. we ensure that the pipeline stages proceed smoothly without any data hazards.
