This allows more latency hiding and less instructionpipeline stalls, and the code runs faster as a result.
这将允许更多的延迟隐藏和更少的指令管道摊位,和代码运行更快。
2
The lower value of CPI means one instruction takes less time to execute. The cycles can be broken down into several parts in terms of how much time is spent in different pipeline stage.
CPI 值低就意味着指令花费的执行时间少。
3
Branch mis-prediction (Processor guesses the wrong branch, so it has to flush the pipeline and load instruction from proper branch again), or.
