Name
void plp_mult_f32(const float32_t * pSrcA, const float32_t * pSrcB, float32_t * pDst, uint32_t blockSize)
Glue code for element-by-element multiplication of 32-bit float vectors.

Functions Documentation

function plp_mult_f32

void plp_mult_f32(
    const float32_t * pSrcA,
    const float32_t * pSrcB,
    float32_t * pDst,
    uint32_t blockSize
)

Glue code for element-by-element multiplication of 32-bit float vectors.

Parameters:

  • pSrcA points to first input vector
  • pSrcB points to second input vector
  • pDst points to output vector
  • blockSize number of samples in each vector

Return: none
