基于动态数据流图的嵌入式系统设计

A Hardware/Software Co-design Approach for Embedded System Based on DDF Model

该文提出一种嵌入式系统软硬件协同设计方法,它以动态数据流图为系统模型对嵌入式系统的功能和性能需求进行描述,由此提供强大的描述、分析能力及可接受的实现规模.通过一种特定的实现结构,以及数据通路的自动综合和实现代码框架的自动生成,设计工作的主体部分可以被有效分解为一系列独立设计任务,能缩短设计周期并提高设计工作的可重用性。

A hardware/software co-design approach for embedded system is proposed in this paper.The approach uses dynamic data flow graph as system model to describe the functional and performance requirements of the designed system,providing powerful description and analysis ability.With the help of a dedicated implementation architecture,an automatic synthesis method for data paths and automatic generation of execution code framework,the main body of design process can be effectively decomposed into a lot of separate design items with the consistency being maintained,which shortens the design cycle and improves the reuse ability of design work.
