Functions Documentation

function plp_mat_copy_stride_i8_parallel

void plp_mat_copy_stride_i8_parallel(
    const int8_t *__restrict__ pSrc,
    uint32_t M,
    uint32_t N,
    uint32_t strideSrc,
    uint32_t strideDst,
    uint32_t nPE,
    int8_t *__restrict__ pDst
)

Glue code to copy an MxN strided 8-bit integers matrix in parallel.

Parameters:

  • pSrc Points to the input matrix of shape MxN
  • M Height of both matrices
  • N Width of both matrices
  • strideSrc Stride of the input matrix (elements between each row)
  • strideDst Stride of the output matrix (elements between each row)
  • nPE Number of cores to use for processing
  • pDst Points to the output matrix of shape MxN

Return: none
