It is generally desirable to reduce the power consumption of embedded systems. Dynamic Voltage and Frequency Scaling (DVFS) is a commonly applied technique to achieve power reduction at the cost of computational performance. Multiprocessor System on Chips (MPSoCs) can have multiple voltage and frequency domains, e.g. per-core. When DVFS is applied to real-time applications, the effects must be accounted...
Electronic devices are expected to accommodate evermore complex functionality. Portable devices, such as mobile phones, have experienced a rapid increase in functionality, while at the same time being constrained by the amount of energy that may be stored in their batteries. Dynamic Voltage and Frequency Scaling (DVFS) is a common technique that is used to trade processor speed for a reduction in...
Energy efficient execution of applications is important for many reasons, e.g. time between battery charges, device temperature. Voltage and Frequency Scaling (VFS) enables applications to be run at lower frequencies on hardware resources thereby consuming less power. Real-time applications have deadlines that must be met otherwise their output is devalued. Dataflow modelling of real-time applications...
