摘要： 提出了一种基于CIG模型的片上通信体系结构设计方法CA-CIG。通过分析CIG模型中功能组件之间的通信关系，并考虑了不兼容协议之间协议转换带来的通信开销和不同的总线宽度对系统通信性能的影响，提出了一种快速有效的片上通信体系结构原型设计方法，集成了通信拓扑体系结构设计、总线宽度配置和总线协议选择等过程，提供了相应的算法实现其中的关键步骤。通过JPEG解码系统证明了CA-CIG设计方法的有效性。

Abstract: This paper proposes an efficient on-chip communication architecture design method (called CA-CIG) based on CIG. Analysing the communication between processing elements given in CIG, and taking into consideration of the communication cost from the transformation between incompatible protocols and the different bus width, CA-CIG presents a fast and effective architecture prototype design method, and integrates the communication topology generation, bus width configuration and the communication protocol selection processes. To automate the design, CA-CIG also provides the related algorithms for the key steps. This paper uses the JPEG decoder application to demonstrate the effectiveness of the method.

Key words: communication architecture, CIG, on-chip communication
