Do you still have access to this?

  Sadly not. I was pretty terrible about version control and saving things from that early in my career. The concept was pretty simple though: division was 1-bit so you could simply do fewer divisions if you had smaller numbers. The first version was something like a BSR -> jump into the divide table. That probably would have been the place to stop, but I was clearly terrible at profiling because I remember adding all sorts of special case logic on top to handle things like powers of two, which likely ended up being slower in practice because cycle times aren't everything.

    > I was pretty terrible about version control and saving things from that early in my career. You and everyone else, I feel. I tried to find some of my early projects from two decades back, and despite having backups floating around on various hard-drives, I could not find them to save my life. I wish I'd accepted the good word of CVS/SVN back then!

  This is not an answer to your question as asked, but the direction it goes may prove interesting: https://lab.whitequark.org/notes/2020-04-06/synthesizing-optimal-8051-code/ https://lab.whitequark.org/notes/2020-04-06/synthesizing-opt... (Found this a while back, mild impostor syndrome moment much)

    whitequark is pretty genius. I think i saw that on her twitter previously but thanks for the trip down memory lane.
