Minimizing the energy consumption and silicon area are usually two major challenges in the design of battery-powered embedded computing systems. Dynamic and Partial Reconfiguration (DPR) opens up promising prospects with the ability to reduce jointly performance and area of compute-intensive functions. However, partial reconfiguration...

Nowadays, System-on-Chip architectures are composed of several execution resources which support complex applications. As it shares silicon area and limits the cost of the global circuit, the embedding of a reconfigurable resource in these SoC provides flexibility to the hardware. In this case, several implementations of the same algorithm,...

Although fairly known for a long time, the vast potential of Dynamic and Partial Reconfigu-ration (DPR) for high energy efficiency is still difficult to exploit, for reasons that are more methodological than purely technical. This work addresses this problem and provides a contri-bution by seeking to improve energy efficient deployment and...

This paper exhaustively explores the potential energy efficiency improvements of Dynamic and Partial Reconfiguration (DPR) on the concrete implementation of a H.264/AVC video decoder. The methodology used to explore the different implementations is presented and formalized. This formalization is based on pragmatic power consumption models of...

In the context of embedded systems development, two important challenges are the efficient use of silicon area and the energy consumption minimization. Hardware accelerated tasks allow to reduce energy consumption of several orders of magnitude, compared to software execution, but these tasks require silicon area and consume power even when...

Designing low power complex embedded systems is a main challenge for corporations in a large number of electronic domains. There are multiple motivations which lead designers to consider low power design such as increasing lifetime, improving battery longevity, limited battery capacity, and temperature constraints, etc. Unfortunately, there is...

Designing low power complex embedded systems is now a critical challenge for a large number of electronic corporations. Low power is generally critical due to its impact on lifetime, battery longevity, battery capacity, temperature constraints, etc. Unfortunately, when a designer needs some power estimations about its design, the methods and...
