A detailed examination of the Pentium's ×3 circuit, explaining its purpose, implementation, and the advanced techniques used to maximize performance.
This webpage discusses the electronic publication of W. Ross Ashby's seminal work 'Introduction to Cybernetics', originally published in 1956. Principia Cybernetica has made this classic text available online, thanks to permissions from the Ashby estate, allowing for wide access. The book is praised for its clear, simple, yet profound insights into cybernetics and systems theory, introducing fundamental concepts like the homeostat, the law of requisite variety, and the principle of self-organization. It's formatted as a PDF for easy reading and printing.
