## Description

## Function Documentation

void arm_q31_to_float | ( | const q31_t * | pSrc,
|  | float32_t * | pDst,
|  | uint32_t | blockSize
| ) |  |

Parameters

  [in] | pSrc | points to the Q31 input vector
  [out] | pDst | points to the floating-point output vector
  [in] | blockSize | number of samples in each vector

Returns
  none

Details
  The equation used for the conversion process is:

          pDst[n] = (float32_t) pSrc[n] / 2147483648;   0 <= n < blockSize.

void arm_q31_to_q15 | ( | const q31_t * | pSrc,
|  | q15_t * | pDst,
|  | uint32_t | blockSize
| ) |  |

Parameters

  [in] | pSrc | points to the Q31 input vector
  [out] | pDst | points to the Q15 output vector
  [in] | blockSize | number of samples in each vector

Returns
  none

Details
  The equation used for the conversion process is:

          pDst[n] = (q15_t) pSrc[n] >> 16;   0 <= n < blockSize.

void arm_q31_to_q7 | ( | const q31_t * | pSrc,
|  | q7_t * | pDst,
|  | uint32_t | blockSize
| ) |  |

Parameters

  [in] | pSrc | points to the Q31 input vector
  [out] | pDst | points to the Q7 output vector
  [in] | blockSize | number of samples in each vector

Returns
  none

Details
  The equation used for the conversion process is:

          pDst[n] = (q7_t) pSrc[n] >> 24;   0 <= n < blockSize.
