)

Matrix multiplication of 32-bit floating-point 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

strided matrix matrix multiplication of a 32-bit floating-point matrices for XPULPV2 extension.
