I used sp_fftSPxSP.
This is a mixed radix, cache optimized routine specially made for c67x.
You can find good docs on the internet.
The sp means single precision. The w and brev arguments will need to
be calculated ahead of time. There is a tool for calculating w. You
have to be very careful when using TI's optimized routines. There are
many special requirements - like padding arrays and an even number of
elements. I suggest you try an example in the emulator to verify it
