对于4096点FFT(4采样/周期),使用连续输入索引/ M间隔输出索引输入/输出索引模式(其中M等于1024),第一个有效输入周期中的输入采样索引为0, 1, 2, 3,第二个周期中的索引为4, 5, 6, 7并以此类推。第一个有效输出周期中的输出采样索引为0, 1024, 2048, 3072,第二个周期中的输出索引为1, 1025, 2049, ...
我参考使用FFTLIB 库, D:\ti\fftlib_k2hx_2_0_0_2\packages\ti\fftlib\src\fft_sp_1d_r2c\fft_sp_1d_r2c_d.c文件中的fft_sp_plan_1d_r2c进行修改做4096点1D FFT变换(因据说这个fft会比较快 ),我看了不少了该函数的手册,但是还是没有搞懂fft_memory_request 的传入参数FFTmemBuffer_t结构体中...

For this situation, there exists many libraries, such as FFTW, that have been rigorously developed, tested, and optimized. Our goal is to use these existing techniques and develop novel implementations to address the more interesting case of FFT in finite fields. We will see that in many ...
ti fftlib分享: TI官方的fftlib使用请问有没有fftlib库的使用实例,比如fft_dp_2d_r2c_ecpy(fft_param_u u, void *edmaState);具体的调用实现,谢谢? dwbsemail 2018-06-21 04:28:09 请问C66x中使用FFTLIB 2.0.0.2库做4096点FFT变换是否比DSPLIB 中 DSPF_sp_fftSPxSP快? 本帖最后由 一只耳朵怪 于 ...
