Design of FIR Filter in MATLAB-DSP Integrated Environment

文章介绍了有限冲激响应(FIR)数字滤波器的原理,以及如何根据工程中所给的参数设计所需的FIR数字滤波器。在MATLAB环境下完成FIR数字滤波器的设计与分析,利用CCSIDE完成数字滤波器的实现,通过CCSLink这一高效的工具完成MATLAB与DSP之间的实时数据传送,在不影响DSP运行的情况下完成DSP的开发。利用这一技术可以快速地对DSP进行控制与调试,极大地缩短了DSP的开发周期,提高了DSP的开发效率。

This paper describes the principle and structure of FIR digital filter, and the design of desired FIR digital filters in accordance with the engineering parameters. The design and analysis of FIR digital filters is completed in the MATLAB environment, the digital filter is implemented by using CCS IDE, and the data between MATLAB and DSP is realized by using CCS Link tool. This technique can accelerate the control and debugging of DSP greatly shorten the development cycle of DSP, thus improving the efficiency of DSP development.
