Understanding Pipelining in Processors

What is the primary purpose of pipelining in a processor?

• To increase the size of the processor

• To improve processor performance

• To reduce the cost of manufacturing

• To decrease the power consumption

Which of the following best describes the concept of pipelining?

• A technique to cool down the processor

• A method to increase the clock speed of the processor

• A technique similar to an assembly line in a factory

• A way to increase the number of cores in a processor

In the context of pipelining, what is the fetch-decode-execute cycle?

• A cycle that increases the processor's power consumption

• A cycle that consists of stages repeated for every instruction

• A cycle that reduces the number of instructions a processor can handle

• A cycle that is only used in multi-core processors

What is the role of registers in the fetch-decode-execute cycle?

• To increase the processor's clock speed

• To keep intermediate results between stages

• To decrease the processor's power consumption

• To store the final output of the processor

Why is a clock signal important in the fetch-decode-execute cycle?

• To increase the processor's temperature

• To synchronise the flow of data between stages

• To reduce the number of instructions executed

• To increase the size of the processor

What happens when one instruction is being executed in a pipelined processor?

• Another instruction is being fetched

• The processor remains idle

• The processor shuts down

• The processor increases its clock speed

How does pipelining affect the execution rate of instructions?

• It decreases the execution rate

• It keeps the execution rate the same

• It increases the execution rate

• It has no effect on the execution rate

Which of the following is a requirement for a task to be suitable for pipelining?

• The task must be able to be broken down into independent subtasks

• The task must be completed in a single step

• The task must require a large amount of memory

• The task must be executed by a single core processor
