)

Matrix multiplication of 16-bit integer matrices kernel for XPULPV2 extension.

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
  • strideA Stride of matrix A (elements between each row)
  • strideB Stride of matrix B (elements between each row)
  • strideC Stride of output matrix (elements between each row)
  • pDstC points to the output matrix

Return: none
