Early Energy Estimation of Networked Embedded Systems Executing Concurrent Software Components

Quanto: Tracking Energy in Networked Embedded Systems

We present Quanto, a network-wide time and energy profiler for embedded network devices. By combining well-defined interfaces for hardware power states, fast high-resolution energy metering, and causal tracking of programmer-defined activities, Quanto can map how energy and time are spent on nodes and across a network. Implementing Quanto on the TinyOS operating system required modifying under ...

Power/Energy Estimation and Optimization for Software-Oriented Embedded Systems

The importance of power reduction of embedded systems has continuously increased in the past years. Recently, reducing power dissipation and energy consumption of a program have become optimization goals in their own right, no longer considered a side-effect of traditional performance optimizations which mainly target program execution time and/or program size. Nowadays, there is an increasing ...

Modeling and visualizing networked multi-core embedded software energy consumption

In this report we present a network-level multi-core energy model and a software development process workflow that allows software developers to estimate the energy consumption of multi-core embedded programs. This work focuses on a high performance, cache-less and timing predictable embedded processor architecture, XS1. Prior modelling work is improved to increase accuracy, then extended to be...

Prototyping Networked Embedded Systems

Networked Embedded Systems

Ten years after the Internet revolution are we standing on the brink of another revolution: networked embedded systems that connect the physical world with the computers, enabling new applications ranging from environmental monitoring and wildlife tracking to improvements in health care and medicine. Only 2% of all microprocessors that are sold today are used in PCs; the remaining 98% of all mi...
