Function Documentation

void arm_q15_to_float	(	q15_t *	pSrc,
		float32_t *	pDst,
		uint32_t	blockSize
	)

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.

void arm_q15_to_q31	(	q15_t *	pSrc,
		q31_t *	pDst,
		uint32_t	blockSize
	)

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.

void arm_q15_to_q7	(	q15_t *	pSrc,
		q7_t *	pDst,
		uint32_t	blockSize
	)

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.
