摘要： 在动态二进制翻译中，热路径的识别和生成是提高二进制翻译器效率的重要环节。为了提高热路径预测的命中率，必须在程序的运行中搜集较为详细的信息，这必然增加系统的开销。因此，在准确率和开销之间做出权衡十分必要。该文在研究现有热路径算法的基础上，提出了一种改进的基于路径的热路径识别和优化算法，并对结果进行了分析。

Abstract: The recognition and creation of hot paths is one of the key factors in promoting the performance of a dynamic binary translator. To promote the accuracy of the hot path prediction, it is necessary to do a more thorough run-time profiling, which will lead to a rise in overhead. So a tradeoff between accuracy and overhead is needed. This paper studies the current profiling strategies and proposes an improved hot path recognition scheme.

Key words: dynamic binary translation, hot path, dynamic optimization
