想在6678上实现4096点的浮点FFT运算,但是我在dsplib3.2.0.0中怎么没有找到实现浮点fft的函数,有哪位高手知道哪里有直接实现浮点fft的函数,是否可以直接用c67xx的dsplib,后者要自己写一个吗?

您好,
我安装的dsplib_c66x_3_1_1_1下面有单精度及双精度浮点的FFT/IFFT,
dsplib_c66x_3_1_1_1\packages\ti\dsplib\src\DSPF_dp_fftDPxDP
dsplib_c66x_3_1_1_1\packages\ti\dsplib\src\DSPF_sp_fftSPxSP
VLFFT是基于sysBios的例程:http://www.deyisupport.com/question_answer/dsp_arm/c6000_multicore/f/53/t/12423.aspx
