I posted this to alt.msdos.programmer a while ago and though that someone
here might be able to help. I've been working (now and then) on writing a
software emulator for the 8087 chip. While I have found references to the
algorithms used by the chip to compute its transcendental functions, the
chip apparently uses some sort of partial CORDIC algorithm with an
interpolation to finish off the result. However, I have not found any of the
details that I need to actually implement these algorithms. If anyone knows
of these details, or where I can find out about them I would appreciate
a line to send me in the right direction. Thanks.
