function plp_mat_mult_i16_parallel

void plp_mat_mult_i16_parallel(
    const int16_t *__restrict__ pSrcA,
    const int16_t *__restrict__ pSrcB,
    uint32_t M,
    uint32_t N,
    uint32_t O,
    uint32_t nPE,
    int32_t *__restrict__ pDstC
)

Glue code for parallel matrix mutliplication of 16-bit integer matrices.

Parameters:

• pSrcA points to the first input matrix
• pSrcB points to the second input matrix
• 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

Glue code for parallel matrix matrix multiplication of a 16-bit integer matrices.
