- The adder at the heart of Intel’s 8087 floating-point chip (righto.com)
In 1980, Intel released the Intel 8087 floating-point coprocessor, a chip that could make math up to 100 times faster. As well as arithmetic and square roots, the 8087 computed transcendental functions including tangent, exponentiation, and logarithms. But it all depended on a 69-bit adder: “The arithmetic heart of the floating-point execution unit is centered about a nanomachine comprised of the adder and its related registers, shifters and control circuitry,” as the patent describes it. In this article, I explain the circuitry of this adder.
- Joseph Goebbels (Wikipedia)
Paul Joseph Goebbels (German: [ˈpaʊ̯l ˈjoːzɛf ˈɡœbl̩s]; 29 October 1897 – 1 May 1945) was a German Nazi politician and philologist who was the Gauleiter (district leader) of Berlin, chief propagandist for the Nazi Party, and then Reich Minister of Propaganda from 1933 to 1945. He was one of Adolf Hitler’s closest and most devoted followers, known for his skills in public speaking and his virulent antisemitism which was evident in his publicly voiced views. He advocated progressively harsher discrimination, including the extermination of the Jews in the Holocaust.
