Hi there,
The paragraph indicates that:
    The integer multiply operation takes 11 cycles to execute, because it does
not use pipeline technique.
    But the floating point multiply operation takes 3 cycles to execute, because
it uses pipeline technique.
So, the integer multiply operation is time consuming rather than floating point
multiply.
