Surprise test

What is the purpose of the Decode Instruction (DI) stage in instruction pipelining?

• Retrieve operands needed for execution

• Calculate where the operands are stored

• Fetch the instruction from memory

• Decode the fetched instruction to determine the operation and operands

What type of hazard occurs when two instructions in the pipeline need the same resource?

• Branch Hazard

• Resource Hazard

• Control Hazard

• Data Hazard

What type of data hazard occurs when an instruction modifies a register or memory location, and the succeeding instruction reads data in that location before the write is complete?

• Read after write (RAW)

• Control Hazard

• Write after write (WAW)

• Write after read (WAR)

Which of the following is NOT a type of pipelining hazard?

• Data Hazard

• Structural Hazard

• Branch Hazard

• Memory Hazard

Which is used to improve pipeline performance by automatically rearranging instructions within a program?

• Branch Prediction

• Loop Buffer

• Multiple Streams

• Delayed Branch
