function plp_mat_sub_stride_i32_parallel

void plp_mat_sub_stride_i32_parallel(
    const int32_t *__restrict__ pSrcA,
    const int32_t *__restrict__ pSrcB,
    uint32_t M,
    uint32_t N,
    uint32_t strideA,

    uint32_t strideY,
    uint32_t nPE,
    int32_t *__restrict__ pDst
)

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

Parameters:

  • pSrcA Points to the first input matrix
  • pSrcB Points to the second input matrix
  • M Height of all matrices
  • N Width of all matrices
  • strideA Stride of matrix A (elements between each row)
  • strideB Stride of matrid B (elements between each row)
  • strideY Stride of output matrix (elements between each row)
  • nPE Number of cores to use for computation
  • pDst Points to the output matrix

Return: none
