摘　　要：提出了基于DSP Builder平台的快速整数离散余弦变换(DCT)的实现方法。首先介绍了整数DCT的原理,然后基于DSP Builder平台、Simulink平台以及电子设计自动化(EDA)平台Modelsim构建了整数DCT的蝶形运算模型。最后,对完整的测试电路进行仿真。结果表明:该方法简单可行,缩短了开发周期,可方便地应用于相关领域。The implementation method of fast integer discrete cosine transform( DCT) based on DSP Builder software was proposed. First,the principle of integer discrete cosine transform was introduced.Then,DSP Builder software,Simulink software and EDA tool of Modelsim were employed to construct the butterfly computation model of integer discrete cosine transform. Finally,the test circuit model was simulated. The experimental results showthat the method is simple and can be conveniently applied to the related fields for the development cycle reduction.
