## Description

## Function Documentation

void arm_q15_to_f16 | ( | const q15_t * | pSrc,
|  | float16_t * | pDst,
|  | uint32_t | blockSize
| ) |  |

Converts the elements of the floating-point vector to Q31 vector.

Parameters

  [in] | pSrc | points to the Q15 input vector
  [out] | pDst | points to the f16 output vector
  [in] | blockSize | number of samples in each vector

Returns
  none

Details
  The equation used for the conversion process is:

          pDst[n] = (float16_t) pSrc[n] / 32768;   0 <= n < blockSize.

void arm_q15_to_float | ( | const q15_t * | pSrc,
|  | float32_t * | pDst,
|  | uint32_t | blockSize
| ) |  |

Parameters

  [in] | pSrc | points to the Q15 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] / 32768;   0 <= n < blockSize.

void arm_q15_to_q31 | ( | const q15_t * | pSrc,
|  | q31_t * | pDst,
|  | uint32_t | blockSize
| ) |  |

Parameters

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

Returns
  none

Details
  The equation used for the conversion process is:

          pDst[n] = (q31_t) pSrc[n] << 16;   0 <= n < blockSize.

void arm_q15_to_q7 | ( | const q15_t * | pSrc,
|  | q7_t * | pDst,
|  | uint32_t | blockSize
| ) |  |

Parameters

  [in] | pSrc | points to the Q15 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] >> 8;   0 <= n < blockSize.
