Abstract :
This paper demonstrates via use of realistic embedded program execution traces, the power and energy savings possible from a variety of dynamic power management techniques. This includes a new variable cluster microarchitecture that allows very dynamic control over its energy/performance characteristics. The traces employed were derived from testbed emulating a planned upcoming deep space mission under a variety of mission scenarios.
