Consumer interest in high-end smart phones is pushing manufacturers to include more and more features and capabilities seen in PC desktops. As the complexity of the designed System-on-Chip increases, pre-silicon performance investigations are difficult to do without appropriate tools and methodologies. Application models for embedded systems are needed for early performance analysis before availability of either hardware or software. Current practice based on traffic generators is not sufficiently accurate to model various realistic use cases. A better option is to replace some of the traffic generators by a more precise representation of the application running on the CPUs. However, development of such representations is a manual and time consuming job. The primary objective of this project is to understand which code structures must be implemented in the application model and which details may be abstracted away so that the application model can be automatically generated.

消费者对高端智能手机的兴趣正在推动制造商加入越来越多的PC台式机特性和功能。随着所设计的片上系统的复杂性增加，如果没有合适的工具和方法，预硅的性能研究是很难进行的。在硬件或软件可用之前，需要嵌入式系统的应用模型来进行早期性能分析。当前基于流量生成器的实践不足以对各种实际用例进行建模。更好的选择是用运行在CPU上的应用程序的更精确表示来替换一些流量生成器。然而，开发这样的表示是一项人工且耗时的工作。该项目的主要目标是了解哪些代码结构必须在应用程序模型中实现，以及哪些细节可以抽象出来，以便自动生成应用程序模型。
