Implementation of Adaptive FIR Filter Based on TMS320VC5402

The article introduced the design and implementation of the adaptive FIR filter based on DSP (digital signal processor). Firstly, simulate experiment of the adaptive FIR filter structure and algorithm is carried out by MATLAB, and adaptive filtering of the input signal added Gauss noise is performed. Simulation waves are given, and the reference data for the DSP designing is provided. On this foundation, TMS320VC5402 DSP chip is selected as the center processor to design and implement the adaptive FIR filter. The hardware system design module, the software system design flow chart and the related assembly code are given. The uniformity of simulation results and measurement results and the filter effect is satisfied.
