Functions Documentation

function plp_cmplx_dot_prod_q32

void plp_cmplx_dot_prod_q32(
    const int32_t *__restrict__ pSrcA,
    const int32_t *__restrict__ pSrcB,
    uint32_t numSamples,
    uint32_t deciPoint,
    int32_t *__restrict__ realResult,
    int32_t *__restrict__ imagResult
)

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

Parameters:

  • pSrcA points to the first input vector
  • pSrcB points to the second input vector
  • numSamples number of samples in each vector
  • deciPoint decimal point for right shift
  • realResult real part of the result returned here
  • imagResult imaginary part of the result returned here

Return: none
