TMS320C6678: FFTLIB example code

Part Number: TMS320C6678
Other Parts Discussed in Thread: FFTLIB

Hi,

My customer is considering using fft_sp_2d_r2c and ifft_sp_2d_c2r kernel with FFTLIB 3.1(bundled in the recent ProcSDK) on C6678, but it seems there is no example code for them.
Usually, TI provides <api_name>_d.c as an example API integration, right ? Unfortunately, I could not see related *_d.c integration in the FFTLIB package. Can you comment on this ?

Best Regards,
Naoki

Hi Naoki,

I've forwarded this to the c66x DSP SW experts. Their feedback should be posted here.

Naoki-san,

FFTLIB is a high performance compute library that is meant to be used along with DSPLIB and OpenMP. My understanding is that for test cases regarding 2D FFTs in this library, you should look for the test cases under fft_omp_sp_2d_r2c and ifft_omp_sp_2d_c2r that has the <api_name>_d.c unit test that you are looking for.

Regard,s
Rahul
