Yes, this article was 100% focused on the substrate bias generator, since I wanted to start with a self-contained piece. I realize it's a bit of a strange focus, but hopefully it was interesting.
As far as the microcode, I'm not sure I understand your question. The microcode is fixed firmware, stepping the 8087 through the procedure for complex operations such as logarithm. Essentially, the microcode has mini-programs that the 8087 runs to perform its functions. I'm still researching how the microcode is actually implemented.
