**Title: Understanding Pipeline Hazards in Instruction Execution****Pipeline Stages:**1. **S1 - Fetch Instruction**: The process of retrieving the instruction from memory.2. **S2 - Decode and Calculate Effective Address**: Decoding the instruction to understand required actions and calculating any necessary addresses.3. **S3 - Fetch Operand**: Gathering the needed data variables for execution.4. **S4 - Execute Instruction**: Performing the computation or operation as dictated by the instruction.5. **S5 - Store Results**: Writing the computed results back to memory or registers.**Code Segments and Instructions:**1. **X = R1 + Y**2. **R1 = R2 + Y**3. **Y = R1 + X****Potential Pipeline Hazards:**Pipeline hazards may occur when instruction stages overlap, leading to conflicts or stalls. In this scenario:- **Data Hazard**: - There is a potential data hazard between instructions. - For example, instruction 3 depends on the result of instruction 1 and potentially instruction 2. If instruction 2 updates R1, the new value must be used in instruction 3. This dependency might lead to a stall until R1 is properly updated in stage S5 of instruction 2.Understanding and managing these hazards is crucial for efficient pipeline processing in computer architecture, minimizing stalls, and ensuring correct execution order.

The three key pipeline hazards that occur in the lining of instruction pipes are: Structural Hazard:…

A 5-stage pipelined processor has instruction Fetch (IF), Instruction Decode (ID), Operand fetch (OF), perform Operation (PO) and Write Operand (WO) stages. The IF, ID, OF and WO stages take 1 clock cycle each for any instruction. The PO stage takes 1 clock cycle for ADD and SUB instructions, 3 clock cycles for MUL instruction, and 6 clock cycles for DIV instruction respectively. Operand forwarding is used in the pipeline. What is the number of clock cycles needed to execute the following sequence of instructions? I0: ADD $t2, $t1, $t2 Il: DIV $t4, $t3, $t2 12: MUL $t6, $t5, $t4 Answer:
The instruction is stored at location 300 with its address field at location 301. The address field has a value of 400. A processor register R1 contains the number 200. Evaluate the effective address if the addressing mode of the instruction is Relative Addressing mode; • Relative: 300 + 200 = 500 • Relative: 302 + 200 = 502 • Relative: 301 + 400 = 701 • Relative: 302 + 400 = 702
