摘要 提出通信信息图提取方法CIG-EM,实现了从系统行为级模型到通信信息图(CIG)模型提取的自动设计流程,以帮助系统设计人员在系统设计的早期设计高效的片上通信体系结构·CIG-EM采用层次化控制/数据流图(HCDFG)模型作为系统的内部表示模型,并建立了从系统描述到CIG模型提取的整个设计流程;引入HCDFG模型的扩展M-HCDFG模型表示函数-功能单元和变量-存储器的映射信息,简化了CIG模型提取的过程;提出了3种模型HCDFG,M-HCDFG和CIG之间的转换算法,实现了其自动转换·CIG-EM能够平滑系统设计流程,减少设计周期·利用JPEG解码程序表明CIG-EM方法的正确性和有效性· A communication information graph extraction method （CIG-EM）is proposed, which automates the CIG extraction process from the system behavior model to help system designers construct efficient on-chip communication architecture in the early stage of system design. CIG-EM adopts hierarchical control/data flow graph （HCDFG） as the internal representation, and presents the overall design flow from the system specification to the CIG extraction. Besides, CIG-EM introduces M-HCDFG, the extension of HCDFG, to denote the function-PE and variable-memory mapping information. The automated transformation approaches between the three models, HCDFG, M-HCDFG and CIG are also provided. The methodology can smooth the design flow and shorten the turn-around time greatly. For an experiment, this method is applied to JPEG decoder application to validate its correctness and effectiveness.
