CSE591 Low Power Architecture

29 Jan 07 Presentation I

Instruction Level Power Dissipation in the Intel XScale Embedded Microprocessor

Tools for power analysis of microprocessors at the microarchitectural level:

• SimpleScalar computer architecture simulator

• Wattch: a framework for architectural-level power analysis and optimizations

This software is based on the SimpleScalar software

Download Wattch

• SimplePower "A cycle accurate energy simulator"
