中文摘要: SimpleScalar是目前国际上常用的一种超标量处理器的性能模拟器。首先分析了SimpleScalar模拟器的内部体系结构，并在此基础上深入剖析了其分支预测部件的实现机制。针对SimpleScalar模拟器分支预测部件只支持基于计数器预测器的局限性，通过深入研究Perceptron-based 分支预测器的实现机制，提出并设计了如何在SimpleScalar模拟器中实现Perceptron-based 分支预测器的方案。对超标量处理器的性能模拟和研究有着实际的意义。

Abstract:SimpleScalar is a superscalar processor monitor which is used widely in performance analysis. This paper first analyzes the internal architecture of SimpleScalar, and on this basis, in-depth analyzes the mechanism to achieve branch prediction. Through an in-depth study of Perceptron-based branch predictor imple- mentation mechanism, it proposes a design to let SimpleScalar support Perceptron-based branch predictor. And this has practical significance for superscalar processor performance modeling and research.
