bytrace，开发人员用于追踪进程轨迹、查看性能的一种工具，主要对内核ftrace进行了封装和扩展，来支持用户态的打点。 16- hdc，开发人员用于调试的命令行工具，通过该工具可以在windows/linux/mac等系统上与开发机或者模拟器进行交互。 17- profiler，旨在为开发者提供一套性能调优平台，可以用来分析内存、性能等问题。 18 19## 系统架构<a

studio的插件进行发布，内部主要包括分为UI绘制、设备管理、进程管理、插件管理、数据导入、数据存储、 数据分析、Session管理、配置管理等模块。 331 332- 设备端主要包括命令行工具、服务进程、插件集合、应用程序组件等模块。设备端提供了插件扩展能力，对外提供了插件接口，基于该扩展能力可以按需定义自己的能力，并集成到框架中来，目前基于插件能力已经完成了实时内存插件和trace插件。详细内容见性能调优组件。 333 334## 相关仓<a name="section1371113476307"></a> 335 336**研发工具链子系统** 337
