This is how FPU emulation worked back in the 8086-386 days. Any patents are long expired or invalidated with prior art.

- garmaine 6y agoNo, unfortunately not. Only if you implement it exactly as it was done back in the day for FPUs. Any deviation and you might run into a more recent patent that covers some aspect of a later implementation, maybe even something seemingly obvious or necessary. This is why it is called a patent “minefield.”
