What's the difference between DSPF_sp_fftSPXSP( ) and DSPF_sp_cfftr2_dit( )?
Where can I find the document on them?
I can only find http://processors.wiki.ti.com/index.php/C674x_DSPLIB
but there is no DSPF_sp_cfftr2_dit( ) here.
I debuged and find that the output of DSPF_sp_cfftr2_dit( ) is bit_reversed, but the DSPF_sp_cfftr2_dit.h file didn't tell me that, where it is documented?
