中文摘要：

随着嵌入式系统规模、复杂度和性能需求的提升，嵌入式系统开发的重点从代码级提前到模型级，模型驱动体系结构成为嵌入式系统开发的主流。结构分析和设计语言（AADL）是一种模型驱动系统工程的新标准，从过程、方法和工具三个方面对其进行研究。讨论模型分析、模型转换和代码生成等相关技术，并将其与OMG的标准建模语言UML进行比较。

英文摘要：

The focus of embedded system development is shifted from the code level to themodel level with the increasing scale,complexity and performance of embedded system and the model-driven architecture stands for a general orientation of embedded system development.~AADL is a new standard of model-driven system engineering.The process,the method and the tools are discussed and the technologies including model analysis,model transformation and code generation are also discussed.At last AADL is compared with UML which is the standard modeling language of OMG.
