fft-arm-0.01.src
- 针对ARM优化过的FFT算法。其中20点,64点,80点的FFT算法。笔者试着加入了256点的FFT -for ARM optimized FFT algorithm off. 20 points, 64 points, 80 points of the FFT algorithm. I tried to join the 256-point FFT
FFT
- 用c实现FFT算法,通过修改该程序可实现32点,64点,128点的FFT运算
自编的FFT算法C程序
- 本人因项目开发需要(基于dsp2812),根据FFT算法原理,用C自编了个FFT程序,可进行64点,128点,256点FFT运算,只要输入对应的参数便可,使用方便灵活!强烈推荐
fft-arm.zip
- 一个用于ARM的基4/基5定点FFT算法,原作者是JDB,后来我扩展过16和256点的计算并用在项目中了,感觉速度还不错。现在重写了基于Linux GCC4的测试程序,可供使用者评估参考。建议安装FFTW3用来精确评估测试结果,相关范例已经在代码中了。,Radix 4/5 FFT routines supporting 16/64/256 and 20/80 calculations. The source originally contributed by JDB, I had extende
