Research on Implementation Method of DSP Using Model-Based Design

为了满足现代DSP算法的快速硬件实现需求,本文分析了传统DSP设计方法的缺点,给出基于模型设计的DSP实现工作流程。整个设计流程从设计的需求开始到最后的硬件实现一直集中在DSP算法的设计模型。通过采用Simulink、FixedPoint Designer、MATLAB Coder和HDL Coder等工具,给出了完整的开发流程。这种基于模型设计的DSP算法开发流程不仅克服了传统设计方法效率低的缺点,而且提高了DSP电路设计的可靠性。

In order to meet the needs of fast hardware implementation of modern DSP algorithm,this paper analyzes the shortcomings of the traditional DSP design method,and gives the workflow of DSP implementation using Model-Based Design. The entire process which starts from design concept to hardware implementation always focuses on design model of DSP algorithm.Using Simulink,Fixed-Point Designer,MATLAB Coder and HDL Coder,the complete development process is given.The development process of DSP algorithm based on model design not only overcomes the disadvantage of low efficiency of traditional design method,but also improves the reliability of the circuit of DSP.
