- 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.
- Seattle Neighborhoods: West Seattle — Thumbnail History (historylink.org)
West Seattle – the oldest and the biggest of Seattle’s neighborhoods – is both a peninsula and a state of mind. The first Euro-American settlers arrived here (on Alki Point) in 1851, but left within a few months, moving to a more agreeable location on the other side of Elliott Bay (the site of present-day downtown Seattle). Orphaned at an early age, isolated by water on three sides, West Seattle has clung to its cultural independence, remaining determinedly aloof even while fighting tenaciously for the bridges, highways, and ferries that have brought it closer to its sprawling neighbor to the east.
