Function Documentation
void arm_q15_to_float | ( | q15_t * | pSrc, |
float32_t * | pDst, | ||
uint32_t | blockSize | ||
) |
Converts the elements of the Q15 vector to floating-point vector.
- Parameters:
-
[in] *pSrc points to the Q15 input vector [out] *pDst points to the floating-point output vector [in] blockSize length of the input vector
- Returns:
- none.
- Description:
The equation used for the conversion process is:
pDst[n] = (float32_t) pSrc[n] / 32768; 0 <= n < blockSize.
Definition at line 63 of file arm_q15_to_float.c.
void arm_q15_to_q31 | ( | q15_t * | pSrc, |
q31_t * | pDst, | ||
uint32_t | blockSize | ||
) |
Converts the elements of the Q15 vector to Q31 vector.
- Parameters:
-
[in] *pSrc points to the Q15 input vector [out] *pDst points to the Q31 output vector [in] blockSize length of the input vector
- Returns:
- none.
- Description:
The equation used for the conversion process is:
pDst[n] = (q31_t) pSrc[n] << 16; 0 <= n < blockSize.
Definition at line 56 of file arm_q15_to_q31.c.
void arm_q15_to_q7 | ( | q15_t * | pSrc, |
q7_t * | pDst, | ||
uint32_t | blockSize | ||
) |
Converts the elements of the Q15 vector to Q7 vector.
- Parameters:
-
[in] *pSrc points to the Q15 input vector [out] *pDst points to the Q7 output vector [in] blockSize length of the input vector
- Returns:
- none.
- Description:
The equation used for the conversion process is:
pDst[n] = (q7_t) pSrc[n] >> 8; 0 <= n < blockSize.
Definition at line 57 of file arm_q15_to_q7.c.
