Energy Efficient Embedded Video Processing Systems

This book provides its readers with the means to implement energy-efficient video systems, by using different optimization approaches at multiple abstraction levels. The authors evaluate the complete video system with a motive to optimize its different software and hardware components in synergy, increase the throughput-per-watt, and address reliability issues. Subsequently, this book provides algorithmic and architectural enhancements, best practices and deployment models for new video systems, while considering new implementation paradigms of hardware accelerators, parallelism for heterogeneous multi- and many-core systems, and systems with long life-cycles. Particular emphasis is given to the current video encoding industry standard H.264/AVC, and one of the latest video encoders (High Efficiency Video Coding, HEVC).

Covers multiple aspects of the complete video processing system and provides a comprehensive guide for designing the system under throughput and energy constraints Highlights new paradigms of system design for embedded video processing, such as hardware accelerator scheduling, heterogeneous multi-cores and content-dependent memory degradation Analyzes video applications in depth, specifically the impact of parallelism on the output quality and investigation of workload variations at runtime Includes supplementary material: sn.pub/extras
