Abstract
To improve power efficiency in JTRS radios, it is crucial to not only apply dynamic power management but also ensure the components are power managed coherently as a system, due to their extensive interactions. We propose a tool-based methodology called ImpacctPro to support modeling, mission-aware power optimization, simulation, and validation of JTRS radios. We have applied ImpacctPro to the Rockwell Collins Step 2B prototype JTRS radio. Experimental results from mission profiles ranging from 30 seconds up to 10 hours show 79% - 89% power reduction, thanks to the mission-aware power management that exploits new opportunities complementary to today's purely workload-driven techniques. ©2004 IEEE.
