- Moscow is the capital and largest city of Russia. The city stands on the Moskva River in Central Russia, with a population estimated at over 13 million residents within the city limits, over 18.8 million residents in the urban area, and over 21.5 million residents in its metropolitan area. The city covers an area of 2,511 square kilometers (970 sq mi), while the urban area covers 5,891 square kilometers (2,275 sq mi), and the metropolitan area covers over 26,000 square kilometers (10,000 sq mi). Moscow is among the world’s largest cities, being the most populous city in its entirety in Europe, the largest urban and metropolitan area in Europe, and the largest city by land area on the European continent.
- Inside the 8086 processor’s instruction prefetch circuitry (righto.com)
The groundbreaking 8086 microprocessor was introduced by Intel in 1978 and led to the x86 architecture that still dominates desktop and server computing. One way that the 8086 increased performance was by prefetching: the processor fetches instructions from memory before they are needed, so the processor can execute them without waiting on the (relatively slow) memory. I’ve been reverse-engineering the 8086 from die photos and this blog post discusses what I’ve uncovered about the prefetch circuitry.
