function plp_mat_mult_trans_i32_parallel

void plp_mat_mult_trans_i32_parallel(
    const int32_t *__restrict__ pSrcA,
    const int32_t *__restrict__ pSrcB,
    uint32_t M,

  • M height of the first input matrix
  • N width of the first input matrix and hight of the second
  • O width of the second input matrix
  • nPE Number of cores to use
  • pDstC points to the output matrix

Return: none
