Final answer:
D) Pipelines in computer architecture increase CPU instruction throughput, reduce the execution time of individual instructions, and speed up utilities. However, they can also increase power consumption.
Step-by-step explanation:
The correct answer is option d) Highly increase power consumption. This statement is not true about pipelines in computer architecture. Pipelines help increase the CPU instruction throughput by allowing the overlapping execution of multiple instructions.
They also reduce the execution time of individual instructions by dividing them into smaller tasks that can be executed simultaneously. Additionally, pipelines speed up the overall execution of a program, making utilities more efficient. However, pipelines can lead to increased power consumption due to the parallel execution of multiple tasks, which requires more resources and energy.
Finally, option D is not true because pipelining generally does not highly increase power consumption. On the contrary, by making the processor more efficient, one could argue that it can lead to lower relative power usage per instruction executed. However, this is nuanced and can depend on the specifics of the processor design.
