Computes an in-place single-precision complex discrete Fourier transform of the input/output vector signal, either from the time domain to the frequency domain (forward) or from the frequency domain to the time domain (inverse). Does not use temporary memory.

Points to a structure initialized by a prior call to the FFT setup data
v. The value supplied as parameter
DSP _create _fftsetup
Log2nof the earlier call to the setup function must equal or exceed the value supplied as parameter
Log2Nof this transform function.
A complex input/output vector.
Stride between elements in
C. The value of
ICshould be 1 for best performance.
The base 2 exponent of the number of elements to process. For example, to process 1024 elements, specify
