Function Documentation

void arm_q7_to_float ( q7_t *  pSrc,
float32_t *  pDst,
uint32_t  blockSize 
)

Converts the elements of the Q7 vector to floating-point vector.

end of park group

Parameters:
[in]*pSrcpoints to the Q7 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] / 128;   0 <= n < blockSize.

Definition at line 74 of file arm_q7_to_float.c.

void arm_q7_to_q15 ( q7_t *  pSrc,
q15_t *  pDst,
uint32_t  blockSize 
)

Converts the elements of the Q7 vector to Q15 vector.

end of inv_clarke group

Parameters:
[in]*pSrcpoints to the Q7 input vector
[out]*pDstpoints to the Q15 output vector
[in]blockSizelength of the input vector
Returns:
none.
Description:

The equation used for the conversion process is:

    
 	pDst[n] = (q15_t) pSrc[n] << 8;   0 <= n < blockSize.

Definition at line 73 of file arm_q7_to_q15.c.

void arm_q7_to_q31 ( q7_t *  pSrc,
q31_t *  pDst,
uint32_t  blockSize 
)

Converts the elements of the Q7 vector to Q31 vector.

end of clarke group

Parameters:
[in]*pSrcpoints to the Q7 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] << 24;   0 <= n < blockSize.

Definition at line 70 of file arm_q7_to_q31.c.
