Hi
        I am looking for references on how to support general 32 bit
integer division (not just invariants) on hardware without dedicated
integer-division support and 64 bit floating point support. However
there is 32 bit floating point support and dedicated hardware to
support 32 bit math functions such as logarithm and exponential. Can
someone please point me to references. I realize this question has
been asked before but they seemed to pertain to invariant
denominators. And invariant perhaps refers to constants...


thanks
