Convert 32-bit floating point value
[Support Functions]

Converts the elements of the floating-point vector to Q15 vector.

Parameters:

[in]	*pSrc	points to the floating-point input vector
[out]	*pDst	points to the Q15 output vector
[in]	blockSize	length of the input vector

Returns:

none.

Description:

The equation used for the conversion process is:

  
 	pDst[n] = (q15_t)(pSrc[n] * 32768);   0 <= n < blockSize.  
 

Scaling and Overflow Behavior:

The function uses saturating arithmetic. Results outside of the allowable Q15 range [0x8000 0x7FFF] will be saturated.

Note:

In order to apply rounding, the library should be rebuilt with the ROUNDING macro defined in the preprocessor section of project options.

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

Parameters:

[in]	*pSrc	points to the floating-point 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] * 2147483648);   0 <= n < blockSize.  
 

Scaling and Overflow Behavior:

The function uses saturating arithmetic. Results outside of the allowable Q31 range[0x80000000 0x7FFFFFFF] will be saturated.

Note:

In order to apply rounding, the library should be rebuilt with the ROUNDING macro defined in the preprocessor section of project options.

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

Parameters:

[in]	*pSrc	points to the floating-point 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] * 128);   0 <= n < blockSize.  
 

Scaling and Overflow Behavior:

The function uses saturating arithmetic. Results outside of the allowable Q7 range [0x80 0x7F] will be saturated.

Note:

In order to apply rounding, the library should be rebuilt with the ROUNDING macro defined in the preprocessor section of project options.
