Pipelining in Computer Architecture Quiz

What is the primary purpose of pipelining in computer architecture?

• To reduce power consumption

• To increase processing speed

• To decrease memory usage

• To simplify the processor design

Which of the following stages is typically found in a pipelined processor?

• Fetch

• Decode

• Execute

• All of the above

What is a pipeline hazard?

• An error in the software

• A situation that causes the pipeline to stall

• A type of processor

• A form of data storage

Which type of hazard occurs due to data dependencies between instructions?

• Structural hazard

• Data hazard

• Control hazard

• Timing hazard

What is a control hazard also known as?

• Data hazard

• Instruction hazard

• Branch hazard

• Execution hazard

In a typical instruction pipeline, what does the 'fetch' stage do?

• Executes the instruction

• Decodes the instruction

• Retrieves the instruction from memory

• Writes the results to memory

Which hazard can be mitigated using branch prediction?

• Data hazard

• Control hazard

• Structural hazard

• Power hazard

What is the role of the 'decode' stage in a pipelined processor?

• To fetch the instruction

• To interpret and prepare the instruction for execution

• To execute the instruction

• To write the results to memory

Which of the following techniques can resolve data hazards?

• Pipelining

• Branch prediction

• Forwarding (or bypassing)

• Caching

What is instruction-level parallelism (ILP)?

• The use of multiple processors

• The parallel execution of instructions in a pipeline

• A type of memory architecture

• A compiler optimization technique
