	)

brief Core function for the floating-point CFFT butterfly process. param[in,out] pSrc points to the in-place buffer of floating-point data type. param[in] fftLen length of the FFT. param[in] pCoef points to the twiddle coefficient buffer. param[in] twidCoefModifier twiddle coefficient modifier that supports different size FFTs with the same twiddle factor table. return none
