CMOS End of the road?

• Is the end of the road in CMOS scaling really in
  sight? If so, is power dissipation the main
  show-stopper?
• Power is a major limiter at the system level
• Intelligent resource management clocks, wires,
  low- vs. high-leakage devices,
• Can mitigate many of the problems

3
Is Power a temporary research issue?

• Power is a metric
• not a research area
• Power-aware architecture research is lt10 years
  old
• Is performance a temporary research issue?
• Depends on application drivers
• Technology trends

4
What solutions at what levels?

• Device
• Circuit
• Logic
• Microarchitecture
• Compiler
• system architecture
• OS
• application

5
Yet another opportunity for Hardware/Software
interaction

• Need
• Clean abstractions
• Portable approaches
• Composable solutions
• Coordinated approaches

Applications
Compilers
Operating Systems
Architecture

Yet another opportunity for Hardware/Software
interaction

• Need
• Clean abstractions
• Portable approaches
• Composable solutions
• Coordinated approaches

Opportunity! Use modest power-management and
low-level system coordination as a distinguishing
feature
