诺基亚手机软件性能分析工具
A Performance Analysis Tool for Nokia Mobile Phone Software
摘要：
性能问题是嵌入式软件系统中经常出现的问题。业绩不佳的原因往往并不明显。瓶颈可能发生在执行路径上的任何软件组件中，因此，对嵌入式软件系统的运行时行为做出贡献的不同组件进行检测和监视是非常重要的。性能分析工具可以通过监控软件的执行并生成易于理解的性能数据来帮助定位嵌入式软件系统中的性能瓶颈。我们维护并进一步开发了一个工具，用于分析诺基亚手机软件的性能。用户可以在四个性能分析报告中进行选择：平均处理器负载、处理器利用率、任务执行时间统计和任务执行时间轴。这些报告中的每一个都提供了有关执行时间花在何处的重要信息。该演示将展示该工具如何帮助识别诺基亚手机软件的性能瓶颈，并更好地了解性能不佳的领域。
英文摘要：
Performance problems are often observed in embedded software systems. The reasons for poor performance are frequently not obvious. Bottlenecks can occur in any of the software components along the execution path. Therefore it is important to instrument and monitor the different components contributing to the runtime behavior of an embedded software system. Performance analysis tools can help locate performance bottlenecks in embedded software systems by monitoring the software's execution and producing easily understandable performance data. We maintain and further develop a tool for analyzing the performance of Nokia mobile phone software. The user can select among four performance analysis reports to be generated: average processor load, processor utilization, task execution time statistics, and task execution timeline. Each of these reports provides important information about where execution time is being spent. The demo will show how the tool helps to identify performance bottlenecks in Nokia mobile phone software and better understand areas of poor performance.
