void arm_negate_f32 (float32_t *pSrc, float32_t *pDst, uint32_t blockSize)
 Negates the elements of a floating-point vector.
 
void arm_negate_q15 (q15_t *pSrc, q15_t *pDst, uint32_t blockSize)
 Negates the elements of a Q15 vector.
 
void arm_negate_q31 (q31_t *pSrc, q31_t *pDst, uint32_t blockSize)
 Negates the elements of a Q31 vector.
 
void arm_negate_q7 (q7_t *pSrc, q7_t *pDst, uint32_t blockSize)
 Negates the elements of a Q7 vector.

Description

-

Negates the elements of a vector.

-
        
-    pDst[n] = -pSrc[n],   0 <= n < blockSize.        
-

The functions support in-place computation allowing the source and destination pointers to reference the same memory buffer. There are separate functions for floating-point, Q7, Q15, and Q31 data types.

void arm_negate_f32 (float32_t * pSrc,
float32_t * pDst,
uint32_t blockSize 
)
-
-
Parameters
- - - - -
[in]*pSrcpoints to the input vector
[out]*pDstpoints to the output vector
[in]blockSizenumber of samples in the vector
-
-
-
Returns
none.

void arm_negate_q15 (q15_t * pSrc,
q15_t * pDst,
uint32_t blockSize 
)
-
-
Parameters
- - - - -
[in]*pSrcpoints to the input vector
[out]*pDstpoints to the output vector
[in]blockSizenumber of samples in the vector
-
-
-
Returns
none.
-
Conditions for optimum performance
Input and output buffers should be aligned by 32-bit
-

Scaling and Overflow Behavior:

-
The function uses saturating arithmetic. The Q15 value -1 (0x8000) will be saturated to the maximum allowable positive value 0x7FFF.
