Which of the following statements is false with regard to instruction ...
The false statement regarding instruction pipelining is option D: The basic goal of instruction pipelining is to achieve a CPI of more than 1.
Explanation:
Instruction pipelining is a technique used in computer architecture to improve the performance of processors by allowing multiple instructions to be executed simultaneously. It breaks down the execution of instructions into smaller stages and allows each stage to be performed concurrently.
1. The basic goal of instruction pipelining is to achieve a CPI of 1:
The CPI (Cycles Per Instruction) represents the average number of clock cycles required to execute one instruction. The goal of instruction pipelining is to reduce the CPI to 1 or as close to 1 as possible. By allowing multiple instructions to be processed concurrently, the overall throughput of the system is increased and the CPI is reduced.
2. Instruction set architectures with simple addressing modes are easier to pipeline:
Complex addressing modes require additional calculations and memory accesses, which can introduce dependencies and hazards in the pipeline. On the other hand, simple addressing modes like register addressing can be easily pipelined as they do not require additional memory accesses.
3. Pipeline hazards can be removed using hardware and compiler techniques:
Pipeline hazards occur when the execution of one instruction depends on the completion of another instruction in the pipeline. These hazards can lead to stalls and reduce the overall performance of the pipeline. However, by using hardware techniques like forwarding and compiler techniques like instruction scheduling, these hazards can be mitigated or eliminated.
4. The basic goal of instruction pipelining is not to achieve a CPI of more than 1:
The goal of instruction pipelining is to reduce the CPI to 1 or as close to 1 as possible. Achieving a CPI of more than 1 would mean that the pipeline is not effectively utilizing the available resources and is not improving the performance of the processor.
Therefore, option D is the false statement as the basic goal of instruction pipelining is to achieve a CPI of 1, not more than 1.
