**Pipeline Stages Explanation:**To analyze the pipeline hazards in the given code segments, we first describe the stages involved in the instruction pipeline:- **S1 – Fetch Instruction:** The CPU retrieves the instruction from memory.- **S2 – Decode and Calculate Effective Address:** The instruction is decoded, and the effective memory address is calculated.- **S3 – Fetch Operand:** The operands required for the execution are fetched.- **S4 – Execute Instruction and Store Results:** The instruction is executed, and the results are stored.**Instructions:**1. `X = R1 + Y`2. `Z = R2 + Y`3. `Y = R1 + X`**Potential Pipeline Hazards:**- **Data Hazard between Instructions 1 and 2:** - Both instructions require the operand `Y` for computation. While instruction 1 is still processing, instruction 2 will try to fetch `Y` before it has been fully processed, potentially leading to a Read After Write (RAW) hazard.- **Data Hazard between Instructions 1 and 3:** - Instruction 3 uses `X`, which is computed in instruction 1. If instruction 3 reaches the stage to fetch its operands before instruction 1 has completed, another RAW hazard occurs.These data dependencies constitute pipeline hazards that can cause delays or require the pipeline to stall until the correct data is available. Understanding these hazards is crucial for optimizing instruction scheduling and enhancing CPU performance in pipelined processor architectures.

Given, S1, S2, S3, S4 are the four stages of the pipeline. S1 denotes the instruction…

Assuming the given pipeline stages, explain (what and where) the potential pipeline hazard(s) (if any) in the following code segments. S1 - fetch instruction S2 - decode and calculate effective address S3 - fetch operand S4 - execute instruction and store results Instructions: 1.X = R1 + Y 2.Z - R2 + Y 3. Y = R1+X
