2 Moore’s Law, Dennard Scaling Dead, Dying, Will Die, …

3 More with Mo re More with Less A New Era ^ o Need new roadmap: A Less Law of Computing

4 More With Less Useful work Waste Hardware Software Abstraction Remove waste: Efficiency Focus on less: Specialization Cut corners: Approximate Less Law: Waste Will Decay Exponentially Hardware Software Abstraction (Architecture) OR …

5 Less is More Computers are everywhere Laps, hands, skin, clothes, things, … Limits for on-chip, but aggregate compute unlimited Unlimited opportunities, exponentials abound But no longer just the processor It’s the system stupid!

6 Recent Turing Awards in Architecture Chuck Thacker: Alto system (PC revolution) ─ Processor, Memory, Display, Mouse, Ethernet Fred Brooks: The definition of architecture (System 360)

7 What will be the next system? What will be the next architecture (abstraction)? Who here will win the Turing award? Exciting New Era
