Functions Documentation

function plp_mat_fill_I_stride_q8s_xpulpv2

void plp_mat_fill_I_stride_q8s_xpulpv2(
    uint32_t N,
    uint32_t stride,
    int32_t fracBits,
    int8_t *__restrict__ pDst
)

Create a strided 8-bit fix-point identity matrix on XpulpV2.

Parameters:

  • N Width and height of the matrix
  • stride Stride of the matrix (elements between each row)
  • fracBits Decimal point for the appropriate scale
  • pDst Points to the output matrix

Return: none

Par: Fix-Point

The diagonal elements will be filled with the value: 1 << fracBits.
