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

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

+
+
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.
