In this paper, we present a systematic approach that transforms the program execution trace into the frequency domain and precisely identifies program phases. The analyzed results can be embedded into program code to mark the starting point and execution characteristics, such as CPI (Cycles per Instruction), of each phase. The so generated information can be applied to runtime program phase prediction. With the precise program phase information, more intelligent software and system optimization techniques can be further explored and developed.

一种基于频域分析的精确节目相位识别方法

在本文中，我们提出了一种将程序执行轨迹转换到频域并精确识别程序阶段的系统方法。分析结果可以嵌入到程序代码中，以标记每个阶段的起点和执行特征，例如CPI（每指令周期数）。如此生成的信息可以应用于运行时程序阶段预测。有了精确的程序阶段信息，可以进一步探索和开发更智能的软件和系统优化技术。
