Virtual-Machine Driven Dynamic Voltage Scaling

In current DVS approaches, voltage scaling decisions are made statically at compile time, and/or dynamically at the OS level. While this has yielded excellent results for a wide range of applications, there is an even better solution for platform independent code (such as Java bytecode) that executes on virtual machines. Such virtual machines have finegrained execution information about the actual workloads that run on them, as opposed to static compilers that at best have off-line profiling data from previous workloads. Based on their high-level model of the actual workload, virtual machines can make DVS decisions with high precision.
