- Interesting BiCMOS circuits in the Pentium, reverse-engineered (righto.com)
Intel released the powerful Pentium processor in 1993, establishing a long-running brand of processors. Earlier, I wrote about the ROM in the Pentium’s floating point unit that holds constants such as π. In this post, I’ll look at some interesting circuits associated with this ROM. In particular, the circuitry is implemented in BiCMOS, a process that combines bipolar transistors with standard CMOS logic.
