void arm_mult_f32 (float32_t *pSrcA, float32_t *pSrcB, float32_t *pDst, uint32_t blockSize)
 Floating-point vector multiplication.
 
void arm_mult_q15 (q15_t *pSrcA, q15_t *pSrcB, q15_t *pDst, uint32_t blockSize)
 Q15 vector multiplication.
 
void arm_mult_q31 (q31_t *pSrcA, q31_t *pSrcB, q31_t *pDst, uint32_t blockSize)
 Q31 vector multiplication.
 
void arm_mult_q7 (q7_t *pSrcA, q7_t *pSrcB, q7_t *pDst, uint32_t blockSize)
 Q7 vector multiplication.
 
-

Description

-

Element-by-element multiplication of two vectors.

-
        
-    pDst[n] = pSrcA[n] * pSrcB[n],   0 <= n < blockSize.        
-

There are separate functions for floating-point, Q7, Q15, and Q31 data types.
