HardwareSoftware Architectures for Low-Power Embedded Multimedia Systems

English | PDF,EPUB(Both True) | 2011 | 240 Pages | ISBN : 1441996915 | 19.2 MB


 

The extreme complexity/energy requirements and context-aware processing nature of muldia applications stimulate the need for adaptive low-power embedded muldia systems with high-performance. Run- adaptivity is required to react to the run- varying scenarios (e.g., quality and performance constraints, available energy, input data).

This book presents techniques for energy reduction in adaptive embedded muldia systems, based on dynamically reconfigurable processors. The approach described will enable designers to meet performance/area constraints, while minimizing video quality degradation, under various, run- scenarios. Emphasis is placed on implementing power/energy reduction at various abstraction levels. To enable this, novel techniques for adaptive energy management at both processor architecture and application architecture levels are presented, such that both hardware and software adapt together, minimizing overall energy consumption under unpredictable, design-/compile- scenarios.

Introduces general concepts and requirements of embedded muldia systems based on advanced video codecs, dynamically reconfigurable processors, and low-power techniques in reconfigurable computing;

Describes novel techniques and concepts for providing adaptivity and energy reduction jointly at processor and application architecture levels;

Provides techniques for enabling run- configurability for quality vs. energy consumption tradeoff at the application level
