Functions Documentation

function plp_mat_scale_stride_i16

void plp_mat_scale_stride_i16(
    const int16_t *__restrict__ pSrc,
    uint32_t M,
    uint32_t N,
    uint32_t strideSrc,
    uint32_t strideDst,
    int16_t scaleFactor,
    int32_t shift,
    int16_t *__restrict__ pDst
)

Glue code for strided matrix scale of 16-bit integer matrices.

Parameters:

  • pSrc Points to the input matrix
  • M Height of both matrices
  • N Width of both matrices
  • strideSrc Stride of input matrix (elements between each row)
  • strideDst Stride of output matrix (elements between each row)
  • scaleFactor Factor to mulitply all elements before shifting
  • shift Amount to shift each element
  • pDst Points to the output matrix

Return: none

Glue code for strided matrix scale of a 16-bit integer matrices.
