摘要
由于小波变换算法的复杂性,直接计算小波变换耗时较长,微机和通用的微处理器在运算速度上难以实现小波变换的实时性要求。定点DSP具有低功耗、高性能的特点,本文结合TI公司的16位定点DSP,将小波变换快速算法用C语言开发,详细说明了小波变换快速算法在定点DSP上的具体实现,解决了小波变换实时、高精度处理的要求,大大提高了小波变换的运算效率。
Due to the comolexitv of the wavelet transformation algorithm, the processing velocity of computer and general microprocessor can hardly meet its real - time requirements. Based on the 16-bit fixed point DSP who has low power con-sumption and high performance presented by TI Company, this article explains the detailed realization process of the wavelet transformation algorithm so as to meet the real-time and high resolution processing requirement in the wavelet transformation algorithm.
