Detailed Description

Function Documentation

tpt_q31_to_f32()

void tpt_q31_to_f32	(	f32_t *	aOutData,
		const q31_t *	aInData,
		uint32_t	aCount )

Converts the elements of the Q31 vector to floating-point vector.

Parameters

[out]	aOutData	points to the floating-point output vector
[in]	aInData	points to the Q31 input vector
[in]	aCount	number of samples in each vector

Returns

none

Details

The equation used for the conversion process is:

    aOutData[n] = (f32_t) aInData[n] / 2147483648;   0 <= n < aCount.
  

tpt_q31_to_f64()

void tpt_q31_to_f64	(	f64_t *	aOutData,
		const q31_t *	aInData,
		uint32_t	aCount )

Converts the elements of the Q31 vector to floating-point vector.

Parameters

[out]	aOutData	points to the floating-point output vector
[in]	aInData	points to the Q31 input vector
[in]	aCount	number of samples in each vector

Returns

none

Details

The equation used for the conversion process is:

    aOutData[n] = (f64_t) aInData[n] / 2147483648;   0 <= n < aCount.
  

tpt_q31_to_q15()

void tpt_q31_to_q15	(	q15_t *	pDst,
		const q31_t *	pSrc,
		uint32_t	blockSize )

Converts the elements of the Q31 vector to Q15 vector.

Parameters

[out]	pDst	points to the Q15 output vector
[in]	pSrc	points to the Q31 input vector
[in]	blockSize	number of samples in each vector

Details

The equation used for the conversion process is:

 pDst[n] = (q15_t) pSrc[n] >> 16;   0 <= n < blockSize.
 

tpt_q31_to_q7()

void tpt_q31_to_q7	(	q7_t *	pDst,
		const q31_t *	pSrc,
		uint32_t	blockSize )

Converts the elements of the Q31 vector to Q7 vector.

Parameters

[out]	pDst	points to the Q7 output vector
[in]	pSrc	points to the Q31 input vector
[in]	blockSize	number of samples in each vector

Details

The equation used for the conversion process is:

 pDst[n] = (q7_t) pSrc[n] >> 24;   0 <= n < blockSize.
