1.8.2.10 mchp_rfft_q31()
void mchp_rfft_q31 (const mchp_rfft_instance_q31 * S, q31_t * pSrc, q31_t * pDst)
Processing function for the Q31 real FFT (ARM-compatible signature).
| in | S |
Points to an mchp_rfft_instance_q31 structure. |
| in,out | pSrc |
Points to the input buffer (modified by this function). |
| out | pDst |
Points to the output buffer. |
Note:
The transform direction (forward/inverse) is determined by the ifftFlagR field set during initialization.
