摘要： 提出了一种通用的接口模型，在SoC设计的接口综合中对IP核的通信接口进行了建模。基于可扩展标记语言(XML)，提出了接口描述文件(IDF-XML)的概念，利用XML的优势对该模型进行描述，并提出了一种转换机制，将IDF-XML中的通信接口信息转换为接口综合中的对象模型。该文以一个简单数码相机的设计为实例，使用建模技术对其中的DCT模块进行接口建模。接口综合算法生成的接口电路将DCT模块与整个系统相连，实现了模块间的平滑通信。

Abstract: This paper presents a generic model for the communication interface of IP cores in SoC design. To represent the interface model in a clear and readable format, this paper proposes an XML-based description medium named IDF-XML using XML technology, which takes its full advantages. Also, a transform mechanism is used to parse IDF-XML and generate object models for interface synthesis. As preliminary experiments, this model is applied to the DCT module of a simple digital camera design. An interface synthesis algorithm is used to generate interface modules between incompatible parts to facilitate smooth communication.
