- Intel introduced the 8086 microprocessor in 1978, and its influence still remains through the popular x86 architecture. The 8086 was a fairly complex microprocessor for its time, implementing instructions in microcode with pipelining to improve performance. This blog post explains the microcode operations for a particular instruction, “ADD immediate”. As the 8086 documentation will tell you, this instruction takes four clock cycles to execute. But looking internally shows seven clock cycles of activity. How does the 8086 fit seven cycles of computation into four cycles? As I will show, the trick is pipelining.
- Seattle Neighborhoods: Denny-Blaine — Thumbnail History (historylink.org)
The Denny-Blaine neighborhood of Seattle is located on Lake Washington between Madison Park and Madrona. It was developed just after the turn of the century by Elbert F. Blaine, an attorney and former Seattle Parks Commissioner, and by Charles L. Denny, son of Seattle founders Arthur Denny and Mary (Boren) Denny. They designed the neighborhood to follow the contours of the land, and included a series of hillside parks. The lots intermingle with streets, lanes, parks, fountains, and cul-de-sacs, virtually all of which have views of Lake Washington.
