- John Milton Cage Jr. (September 5, 1912 – August 12, 1992) was an American composer and music theorist. A pioneer of indeterminacy in music, electroacoustic music, and non-standard use of musical instruments, Cage was one of the leading figures of the post-war avant-garde. Critics have lauded him as one of the most influential composers of the 20th century. He was also instrumental in the development of modern dance, mostly through his association with choreographer Merce Cunningham, who was also Cage’s romantic partner for most of their lives.
- 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.
