function plp_dot_prod_f32s_xpulpv2

void plp_dot_prod_f32s_xpulpv2(
    const float32_t *__restrict__ pSrcA,
    const float32_t *__restrict__ pSrcB,
    uint32_t blockSize,
    float32_t *__restrict__ pRes
)

Glue code for dot product of 32-bit float vectors.

Parameters:

  • pSrcA points to the first input vector
  • pSrcB points to the second input vector
  • blockSize number of samples in each vector
  • pRes output result returned here

Return: none
