摘要
Itanium2处理器以寄存器组的形式提供的性能监视单元实现了在程序运行过程中捕捉微结构事件的功能。文中介绍了以Linux为Itanium2的性能监视单元提供的接口perfmon为基础的开发相对高端的性能分析工具的方法,以实现对这些由性能监视硬件提供的数据进行综合处理利用。
Itanium2 processors are providing hardware support in the form of performance registers that help to capture microarchitectural events that occur during the running of a program. In this paper, we introduce the method to develop the application performance analysis tool based on perfmon under Linux that can assemble various types of complex performance related data available from the performance registers and provide a high level summary of the data.
