快速小波变换的定点DSP实现

Implementation of fot to fixed-point digital signal processor

介绍了小波变换理论及其快速Mallat塔式算法及应用TMS320C2xx系列定点DSP实现这种算法的方法,仿真研究表明,利用定点DSP进行小波变换具有良好的实时性和精度,是工控领域的理想选择.

In this paper,the wavelet theory and fast Mallat algorithm were described. And the implementation of the algorthm was given correspondingly to 16bit fixedpoint DSP from Texas Instruments. The result of simulation referred to the wavelet transform of fixedpoint DSP has good realtime and higher presicion, and is good choice in industrial control field.
