- Intel’s 386 processor (1985) was an important advance in the x86 architecture, not only moving to a 32-bit processor but also switching to a CMOS implementation. I’ve been reverse-engineering parts of the 386 chip and came across two interesting and completely different circuits that the 386 uses to implement an XOR gate: one uses standard-cell logic while the other uses pass-transistor logic. In this article, I take a look at those circuits.
- Bering Strait (Wikipedia)
The Bering Strait (Russian: Берингов пролив, romanized: Beringov proliv) is a strait between the Pacific and Arctic oceans, separating the Chukchi Peninsula of the Russian Far East from the Seward Peninsula of Alaska. The present Russia-United States maritime boundary is at 168° 58’ 37" W longitude, slightly south of the Arctic Circle at about 65° 40’ N latitude. The Strait is named after Vitus Bering, a Danish explorer in the service of the Russian Empire.
