void arm_cfft_mag_bitreversal_f32 ( float32_t *  pSrc,
uint16_t  fftSize,
uint16_t  bitRevFactor,
uint16_t *  pBitRevTab 
)

In-place bit reversal function for cfft magnitude process.

Parameters:
[in,out]*pSrcpoints to the in-place buffer of floating-point data type.
[in]fftSizelength of the FFT.
[in]bitRevFactorbit reversal modifier that supports different size FFTs with the same bit reversal table.
[in]*pBitRevTabpoints to the bit reversal table.
Returns:
none.
