Using Virtual System Prototyping Technology to Optimize Real-time Systems for Power

This paper first introduces the concept of virtual prototypes (VPs) and virtual system prototypes (VSPs). Next, the paper discusses how VSPs can be used to model, analyze, and optimize real-time systems in the context of power. Finally, the paper presents results from some real-world experiments showing how small changes in the hardware architecture and software algorithms can significantly affect the power consumption of a system.
