Processor Pipelining Quiz

What is the main purpose of pipelining in a processor?

• To decrease the speed of the processor

• To reduce the number of registers used

• To improve efficiency and performance

• To increase the number of instructions executed simultaneously

What is the analogy used to explain pipelining in the video?

• Baking a cake

• Writing and sending invites for a party

• Building a house

• Planning a vacation

What is the main limitation of pipelining in a processor?

• It slows down the fetch-decode-execute cycle

• It causes the processor to overheat

• It requires a large amount of memory

• It may not benefit programs with branching instructions

How does pipelining improve the efficiency of a processor?

• By increasing the number of registers used

• By allowing multiple instructions to be executed simultaneously

• By reducing the speed of the processor

• By decreasing the size of the CPU cache

What is the purpose of the arithmetic pipeline in a processor?

• To manage the CPU cache

• To improve the efficiency of arithmetic operations

• To execute branching instructions

• To handle the fetch-decode-execute cycle

What happens when a program with branching instructions is being pipelined?

• The pipeline needs to be flushed

• The program experiences no impact

• The program runs faster

• The processor becomes more efficient

What is the effect of pipelining on the fetch-decode-execute cycle?

• It causes the cycle to skip instructions

• It slows down the cycle

• It speeds up the cycle

• It has no impact on the cycle

How can the speed of a processor be increased further?

• By reducing the number of instructions executed simultaneously

• By increasing the number of registers used

• By flushing the pipeline more frequently

• By using advanced pipelining techniques

What is the purpose of the instruction pipeline in a processor?

• To manage the CPU cache

• To handle arithmetic operations

• To execute branching instructions

• To move instructions through the processor

What is the main benefit of using pipelining in a processor?

• It allows for more efficient use of registers and CPU cache

• It reduces the number of instructions executed simultaneously

• It limits the number of instructions that can be executed

• It slows down the fetch-decode-execute cycle
