Function Documentation
void arm_negate_f32 | ( | float32_t * | pSrc, |
float32_t * | pDst, | ||
uint32_t | blockSize | ||
) |
Negates the elements of a floating-point vector.
- Parameters:
-
*pSrc points to the input vector *pDst points to the output vector blockSize number of samples in the vector
- Returns:
- none.
Definition at line 59 of file arm_negate_f32.c.
void arm_negate_q15 | ( | q15_t * | pSrc, |
q15_t * | pDst, | ||
uint32_t | blockSize | ||
) |
Negates the elements of a Q15 vector.
- Parameters:
-
*pSrc points to the input vector *pDst points to the output vector blockSize number of samples in the vector
- Returns:
- none.
Scaling and Overflow Behavior:
- The function uses saturating arithmetic. The Q15 value -1 (0x8000) will be saturated to the maximum allowable positive value 0x7FFF.
Definition at line 54 of file arm_negate_q15.c.
void arm_negate_q31 | ( | q31_t * | pSrc, |
q31_t * | pDst, | ||
uint32_t | blockSize | ||
) |
Negates the elements of a Q31 vector.
- Parameters:
-
*pSrc points to the input vector *pDst points to the output vector blockSize number of samples in the vector
- Returns:
- none.
Scaling and Overflow Behavior:
- The function uses saturating arithmetic. The Q31 value -1 (0x80000000) will be saturated to the maximum allowable positive value 0x7FFFFFFF.
Definition at line 54 of file arm_negate_q31.c.
void arm_negate_q7 | ( | q7_t * | pSrc, |
q7_t * | pDst, | ||
uint32_t | blockSize | ||
) |
Negates the elements of a Q7 vector.
- Parameters:
-
*pSrc points to the input vector *pDst points to the output vector blockSize number of samples in the vector
- Returns:
- none.
Scaling and Overflow Behavior:
- The function uses saturating arithmetic. The Q7 value -1 (0x80) will be saturated to the maximum allowable positive value 0x7F.
