- 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.

GAMMA PER (Gamma Persei). The naming of stars at times seems to have little to do with their brightnesses. All the first magnitude stars, and most of the second magnitude visible from classical lands, have names (an outstanding exception being Gamma Cassiopeiae), but from there on the naming is erratic.
- Gamma Persei (Wikipedia)
Gamma Persei (Gamma Per, γ Persei, γ Per) is a binary star system in the constellation Perseus. The combined apparent visual magnitude of the pair is +2.9, making it the fourth-brightest member of the constellation. The distance to this system is of roughly 221 light-years (68 parsecs) with a 1% margin of error. About 4° to the north of Gamma Persei is the radiance point for the annual Perseid meteor shower.
