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]*pSrcpoints to the Q15 input vector
[out]*pDstpoints to the floating-point output vector
[in]blockSizelength 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 77 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]*pSrcpoints to the Q15 input vector
[out]*pDstpoints to the Q31 output vector
[in]blockSizelength 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 70 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]*pSrcpoints to the Q15 input vector
[out]*pDstpoints to the Q7 output vector
[in]blockSizelength 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 71 of file arm_q15_to_q7.c.
