Branch prediction techniques are described that can improve the performance of pipelined microprocessors. A microprocessor with a hierarchical branch prediction structure is presented. The hierarchy of branch predictors includes: a multi-cycle predictor that provides very accurate branch predictions, but with...
分支预测器的misprediction会给流水线带来高延迟与额外功耗,设计一个合适的分支预测器能极大地提高处理器性能与显著改善处理器功耗。比如,在实际的处理器里面(ICCD,An optimized scaled neural branch predictor)使其misprediction减半,能提高13%处理器的性能。 论文主要总结了动态分支预测的研究现状。下图展示了论文的...

Branch prediction techniques are utilized to minimize the number of clock cycles that are wasted when a conditional branch is taken. In the translate stage, the branch history table 223 maintains a historical record of the outcomes of conditional jump instructions that have been previously executed ...

Correctly predicting the direction that branches will take is increasingly important in today's wide-issue computer architectures. The name program-based branch prediction is given to static branch prediction techniques that base their prediction on a program's structure. In this paper, we investigate...

The second lab was about exploring branch prediction and evaluating various predictors for their impact on program execution. The PIN tool was used again. The primary objective was to delve into branch prediction techniques and assess different predictors' performance in terms of mispredictions and acc...
