Abstract

In order to quickly implement an embedded system that is mainly based on software, two orthogonal approaches have been proposed: platform-based Design, which maximizes the reuse of components; and model driven development, which rises the abstraction level by using object-oriented concepts and UML. However, with this increasing of the abstraction level, software engineers do not have an exact idea of the impact of their modeling decisions on important issues such as performance, energy, and memory footprint for a given platform. In our approach, analytical estimation of data and program memory, performance, and energy are obtained directly from UML models. Experimental results show a very small estimation error when software components are reused and their costs on the target platform are already known. Real-life applications are modeled in different ways and demonstrate the effectiveness of the estimates in an early design space exploration, allowing the designer to quickly compare different modeling solutions, with estimation errors as low as 5%

基于uml评估的早期嵌入式软件设计空间探索

为了快速实现以软件为主的嵌入式系统，提出了两种正交的方法:基于平台的设计，最大限度地实现了组件的重用;以及模型驱动开发，它通过使用面向对象的概念和UML来提高抽象层次。然而，随着抽象级别的增加，软件工程师并不能准确地了解他们的建模决策对重要问题的影响，例如给定平台的性能、能量和内存占用。在我们的方法中，对数据和程序内存、性能和能量的分析估计是直接从UML模型中获得的。实验结果表明，当软件组件被重用并且它们在目标平台上的成本已经已知时，估计误差非常小。实际应用以不同的方式建模，并在早期的设计空间探索中证明了估计的有效性，允许设计人员快速比较不同的建模解决方案，估计误差低至5%
