	Name
void	plp_mat_trans_f32_parallel(const float restrict pSrc, uint32_t M, uint32_t N, uint32_t nPE, float restrict pDst) Glue code for parallel matrix transpose of 32-bit floating-point matrices.

Functions Documentation

function plp_mat_trans_f32_parallel

void plp_mat_trans_f32_parallel(
    const float *__restrict__ pSrc,
    uint32_t M,
    uint32_t N,
    uint32_t nPE,
    float *__restrict__ pDst
)

Glue code for parallel matrix transpose of 32-bit floating-point matrices.

Parameters:

• pSrc Points to the input matrix of shape MxN
• M Height of the input matrix and width of the output matrix
• N Width of the input matrix and height of the output matrix
• nPE Number of cores to use for computation
• pDst Points to the output matrix of shape NxM

Return: none

Par: This function will use plp_mat_trans_i32p_xpulpv2 for its computation.

Glue code for parallel matrix transpose of a 32-bit float*ing-point matrices.
