摘要

代码的推测执行正在成为提高流水线处理器性能的一项关键技术。我们研究了基于分支执行历史来预测程序执行路径的方案。在先前工作的基础上，我们提出了一个模型，用于分析使用各种推测执行方案的流水线的有效加速。接下来，我们对各种投机执行方案进行随机分析。最后，我们以涵盖我们研究的几个设置的模拟来结束。

Dynamic schemes for speculative execution of code

Speculative execution of code is becoming a key technique for enhancing the performance of pipeline processors. We study schemes that predict the execution path of a program based on the history of branch executions. Building on previous work, we present a model for analyzing the effective speedup from pipelining using various schemes for speculative execution. We follow this with stochastic analyses of various speculative execution schemes. Finally, we conclude with simulations covering several of the settings we study.
