摘　　要：随着片上系统(SOC)技术的发展,越来越多的功能模块被集成到单一芯片中。适合硬件描述的HDL语言很难满足实现复杂算法功能的要求,C++等高级语言可以高效地描述算法功能,但是在综合和验证时遇到很大困难。文章介绍了一种允许使用C和VHDL独立描述原始模块,通过创建统一内部模型IIR的办法实现对功能元件和算法模块的混合处理。IIR内部模型以XML文件格式作为外部存储,能够方便地被划分、综合、验证等处理程序使用,避免了重复的原始描述文件分析,提高了研发效率。With the development of System-On-Chip(SOC),more and more function modules are integrated into a chip.HDL language,which fits for hardware description,is not satisfying for complex algorithmic function,and high language such as C++can describe algorithmic function effectively suffering from logic synthesis and verification.This paper rep-resents a method,which can deal with function components and algorithmic modules together through describing original modules with C or VHDL and creating uniform internal model(IIR).IIR internal model saves as XML format file exter-nally and can be used by partition,synthesis,and verification tools.Analyzing original description repeatedly is avoided and the efficiency of research is improved.
