1.8.2.6 mchp_cfft_q31()

void mchp_cfft_q31 (const mchp_cfft_instance_q31 * S, q31_t * pSrc, uint8_t ifftFlag, uint8_t bitReverseFlag)

Processing function for the Q31 complex FFT.

Parameters:
in	S	Points to an instance of the Q31 CFFT structure.
in,out	pSrc	Points to the complex data buffer (in-place).
in	ifftFlag	0 = forward FFT, 1 = inverse FFT.
in	bitReverseFlag	0 = no bit reversal, 1 = enable bit reversal.

Note:

The CFFT applies 1/2 scaling per stage, so the output is scaled by 1/N for the forward transform.
