摘　　要：目前的软硬件协同设计方法都有其局限性,主要表现在:缺乏必要的模型映射机制、不同语言描述的软硬件设计容易造成不一致现象。经过分析和研究,该文提出了一个软硬件协同设计流程,它基于CDM模型,支持从系统需求描述出发、通过设置各描述组件的参数,自动产生CDM模型。利用SystemC的软硬件描述功能,对CDM模型进行映射和绑定操作,自动生成SystemC可执行程序,使软硬件代码无缝联接。模型经过多次细化和验证,从而提高设计质量和缩短设计周期。最后通过一个实例说明该方法的设计特点。Nowadays various hardware/software co - design methodologies have their limits, such as lack of necessary mapping mechanism, disaccord caused by hardware/software design described with different languages. A co - design flow is proposed after analysis and research. Based on a CDM model, the flow can describe system requirements, set parameters of components and automatically generate CDM models. Using systemc description, the mapping and binding are made to the models, and executable SystemC programs are automatically generated and hardware/software codes are linked seamlessly. Repetitive refinement and verification of models can improve design quality and shorten design periods. Finally a case shows the characteristics of the co - design method.
