Computer Architecture • Hot(-est) Topic • Multi-billion dollar industry • Intel - $40 billion • More than 100 International Conferences • A conference every 3 days (and lasts 3 days) • Extremely fast pace of innovation • Had transportation industry kept pace • We could keep car in our pockets • We could travel between any two points on earth in a fraction of a second • New car would cost less than a cent • “Not a dry and dreary field where progress is glacial and new ideas atrophy from neglect” • Patterson and Hennessy, “Computer Organization and Design” • Enabler of the Information Revolution in history for Civilization • After Agricultural Revolution, Industrial Revolution
Technology Trends: Moore’s Law • In 1965, Gordon Moore, co-founder of Intel predicted that the number of transistors on a chip will double every 1.5 years • True since since 1980! 8000X increase
How small is it? Cell processor contains more than 250 million transistors ENIAC had 18,000 vacuum tubes The original transistor built by Bell Labs in 1947 could be held in your hand, while hundreds 45nm transistors can fit on the surface of a single red blood cell.
Technology Trends: Processor Performance Year • How fast is it? • A 45nm transistor can switch on and off approximately 300 billion times a second. A beam of light travels less than a tenth of an inch during the time it takes a 45nm transistor to switch on and off.
