Today’s Agenda • What is architecture? • Why is it important? • At the highest level, where is architecture today? Where is it going? • What’s in this class? 2

What is architecture? • How do you build a machine that computes? • Quickly, safely, cheaply, efficiently, in technology X, for application Y, etc. Civilization advances by extending the number of important operations which we can perform without thinking about them. -- Alfred North Whitehead

Why study architecture? • As CEs or CSs you should understand how computers work • Processors are the basis for everything in CS (except theory) • They are where the rubber meets the road. • Performance is important • Faster machines make applications cheaper • Understanding hardware is essential to understanding how systems behave • It’s cool! • Microprocessors are among the most sophisticated devices manufactured by people • How they work (and even that they work) as reliably and as quickly as they do is amazing. • Architecture is undergoing two simulatenous revolution -- Multicore and mobility • The future is uncertain • Opportunities for innovation abound. 11

Performance and You! • Live Demo 12

Building Microprocessors • Chips are made of silicon • Aka “sand” • The most abundant element in the earth’s crust. • Extremely pure (<1 part per billion) • This is the purest stuff people make

Building Blocks: Transistors

Building Blocks: Wires

State of the art CPU • 1-2 Billion xtrs • 32nm features • 3-4Ghz • Several 100 designers • >5 years • $3Billion fab • >150 GFLOPS 19

Current state of architecture

Since 1940

Since 1940 • Plug boards -> Java • Hand assembling -> GCC • No OS -> Windows Vista

Since 1940 • Plug boards -> Java • 50,000 x speedup • Hand assembling -> GCC • >1,000,000,000 x density • No OS -> Windows (Moore’s Law) Vista Flexible performance is a liquid asset

Moore’s Law: Raw transistors

The Importance of Architecture • We design smarter and smarter processors • Process technology gives us about 20% performance improvement per year • Until 2004, performance grew at about 40% per year. • Architecture is responsible for half the gains in CPU performance
