Understanding Processor Pipelining

What is the main purpose of using pipelining in processors?

• To increase the size of the processor

• To enhance the graphics performance

• To reduce the power consumption

• To improve the efficiency of instruction processing

In the analogy of writing invites, what role does the second friend play?

• Addressing the envelopes

• Sending out the invites

• Placing invites in envelopes and attaching stamps

• Writing the invites

How does pipelining improve the efficiency of a processor?

• By using more power

• By reducing the number of instructions

• By increasing the clock speed

• By executing multiple instructions at the same time

What happens during the fetch stage in the pipelining process?

• The instruction is executed

• The instruction is stored

• The instruction is decoded

• The instruction is retrieved from memory

What is the role of the ALU during pipelining?

• To store instructions

• To perform arithmetic or logic operations

• To decode instructions

• To fetch instructions

What is a potential problem with pipelining when dealing with branching instructions?

• It reduces the clock speed

• It may require flushing the pipeline

• It causes the processor to overheat

• It increases the power consumption

What does 'flushing the pipe' mean in the context of pipelining?

• Clearing out instructions that are no longer needed

• Enhancing the graphics performance

• Reducing the number of instructions

• Increasing the speed of instruction execution

Why might a program with many branching instructions not benefit from pipelining?

• It requires more power

• It causes more heat

• It reduces the clock speed

• It may lead to frequent pipeline flushing

What are the two types of pipelines mentioned in the video?

• Instruction Pipeline and Arithmetic Pipeline

• Data Pipeline and Control Pipeline

• Fetch Pipeline and Decode Pipeline

• Memory Pipeline and Cache Pipeline

What is the key question posed at the end of the video?

• How can the processor size be increased?

• How can the speed of a processor be increased further?

• How can the graphics performance be enhanced?

• How can the power consumption be reduced?
