DESCRIPTION:DVFS (Dynamic Voltage and Frequency Scaling) is a technique to 
 reduce energy consumption of a computer system. A CPUfreq governor scales 
 the frequency of system CPU\, which in turn affects CPU power performance.
  Each governor has its own unique behavior\, purpose\, and suitability in 
 terms of workload.\n\nComputer architecture researchers commonly use softw
 are simulation to prototype and evaluate their ideas. The Gem5 simulator i
 s a modular platform for computer-system architecture research\, encompass
 ing system-level architecture as well as processor microarchitecture. McPA
 T is the first integrated power\, area\, and timing modeling framework for
  multicore processors.\n\nIn this talk\, We examine the power consumption 
 of different Mibench benchmarks run under different CPUfreq governors\, us
 ing Gem5 with full-system DVFS modeling and McPAT. MiBench used in the exp
 eriment is a free\, commercially representative embedded benchmark suite\,
  consisting of six categories including: Automotive and Industrial Control
 \, Network\, Security\, Consumer Devices\, Office Automation\, and Telecom
 munications\, which are C applications targeting specific areas of the emb
 edded market. We chose one application from each of the six categories of 
 applications for our study.\n\nWe describe how to choose a CPUfreq governo
 r and run Mibench benchmark\, how to derive the power consumption of each 
 benchmark under each governor and discuss what kind of benchmark each gove
 rnor is suitable for.\n\nSpeaker(s): HL\, \n\nAntigonish\, NS\, Nova Scoti
